Part I. GENERAL ASPECTS Food engineering Vocabulary of the text Food engineering – технология продуктов питания Food production – производство продуктов питания Agricultural engineering – технология в сельском хозяйстве Chemical engineering – химическая технология Genetic engineering – генная инженерия Implementation – осуществление, выполнение Emulsification - эмульгирование Comminution – дробление, превращение в порошок Raw materials – сырьё, сырые материалы Large-scale manufacture – крупномасштабное производство Dicing – нарезание в форме кубиков Fibril – тонкое нервное волокно Food engineering refers to the engineering aspects of food production and processing. Food engineering includes, but is not limited to, the application of agricultural engineering and chemical engineering principles to food materials. Genetic engineering of plants and animals is not normally the work of a food engineer. Food engineering is a very wide field of activities. Among its domain of knowledge and action are: Design of machinery and processes to produce foods Design and implementation of food safety and preservation measures in the production of foods Biotechnological processes of food production Choice and design of food packaging materials Quality control of food production Food engineering research is based on mathematical modelling of phenomena occurring in the food processing chain. Its scientific foundation is heat and mass transfer, fluid mechanics, biophysics, colloid science and physical chemistry, and understanding of compositional and structural complexities of foods and biomaterials. The unit operations studied include membrane separations, mixing, emulsification, cleaning, osmotic dehydration, pulsed electric field application and comminution. Chemical engineering is the branch of engineering that deals with the application of physical scienc (e.g. chemistry and physics), with mathematics, to the process of converting raw materials or chemicals into more useful or valuable forms. As well as producing useful materials, chemical engineering is also concerned with pioneering valuable new materials and techniques, an important form of research and development. A person employed in this field is called a chemical engineer. Chemical engineering largely involves the design and maintenance of chemical processes for large-scale manufacture. Chemical engineers in this branch are usually employed under the title of process engineer. The development of the large-scale processes characteristic of industrialized economies is a feat of chemical engineering, not chemistry. Indeed, chemical engineers are responsible for the availability of the modern high-quality materials that are essential for running an industrial economy. Dairy Engineering and Technology The group is working with education as well as research in dairy technology. The research program is focused towards process engineering and technology issues regarding milk and milk systems. Studies on structure and physico-chemical properties of caseins, whey proteins, peptides and milk lipid systems and effect of changes of environmental conditions and functionality are of principal interest. Further, effects of processing, processing parameters and fouling on individual milk components and dairy products like cheese and yoghurt are also main research activities. Experimental techniques involves studies by 2-D electrophoresis, light scattering techniques, DSC, ellipsometry, atomic force microscopy, Cryo-TEM, as well as fluid and solid rheology. Fluid dynamics and flow effects in processing equipment studies comprising effects of the flow field on heat and mass transfer and the fluid mechanical effects on components of the product. Examples are impinging jet heat transfer in ovens, transport of surfactants to interfaces in emulsification processes, adsorption of proteins on product contact surfaces, drop break-up in homogenisers and mixing processes. Used experimental methods are particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) in collaboration with Division of Fluid Mechanics. Numerical simulation using computational fluid dynamics (CFD) and the development of mathematical models are important activities. Meat- and fibre products The research in meat products, such as ham, beef burgers and emulsion sausages, and fibre products, for example tomato ketchup, is focused on the physical-chemical background of the quality of these products and how these properties vary in relation to processing. Relevant processes for meat products are marinating, salting, dicing, comminuting, mass- and heat transfer during cooking of the product. For tomato ketchup the micro-structural changes are followed on pumping and heating/cooling in heat exchangers. An important research area within meat research is to explain the relation between eating quality and water-holding of the meat product and its micro-structure on both a molecular and colloidal level. This approach is also imaged by the titles of the three latest PhD thesis: Waterand fat-holding in comminuted meat products, 2001, Factors controlling meat quality of pork in relation to breed and RN genotype, 2002 and The mechanisms controlling heat and mass transfer in comminuted meat products, 2004. The research in the fibre area is mainly focused on two approaches. The first one deals with tomato ketchup, which is a suspension of cell wall material, such as cellulose fibrils, hemi-cellulose and pectins. The rheological behaviour under flow (heating, cooling and pumping) and under gravity alone (serum-separation) is studied. The second one concerns dietary fibres as fat replacer in protein-rich foods, such as cheese, sausages, beef burgers and liver paté. The aim of these studies is to find out what physical-chemical properties of the fibres that from a sensory point of you make it substitute fat in protein-rich food. Membrane Technology research covers mainly nanofiltration, ultrafiltration, membrane emulsification, and pervaporation. Transport phenomena, membrane characterisation and fouling and cleaning as well as process and applications development and design are studied and modelled. EXERСISES 1.Answer the questions: 1.

Give the summary of the text. Biotechnology Vocabulary of the text Biotechnology - биотехнология Exploitation - эксплуатация To manipulate – манипулировать, воздействовать, влиять, управлять To manufature biological products – производить биологическую продукцию Drugs – лекарства, медикаменты Gene splicing – сращивание генов Hybrid - гибрид Livestock – живой инвентарь домашний скот Genetic disorder – генетическое расстройство Dairying – производство, хранение и продажа молочных продуктов To surpass – превосходить, превышать, перегонять Pasteurization - пастеризация To encompass – включать в себя Artificial selection – искусственный отбор Indigenous – природный, врождённый Bioremediation – биологическое лечение Biotechnology is technology based on biology especially when used in agriculture, food science, and medicine; the use of biological processes, as through the exploitation and manipulation of living organisms or biological systems, in the development or manufacture of a product or in the technological solution to a problem. As such, biotechnology is a general category that has applications in pharmacology, medicine, agriculture, and many other fields. The techniques of genetic engineering have been used to manipulate the DNA (genetic material) of bacteria and other organisms to manufacture biological products such as drugs (insulin, interferon, and growth hormones). A common technique involved in this process is gene splicing, in which a gene that produces a desired product can be inserted into bacterial DNA. Bacteria can then be grown in large quantities and processed to extract the desired substance; specially cultured plant and animal cells can be similarly grown and processed. Hybrids of cancer and antibody-producing cells (hybridomas) have been cloned in the laboratory to produce experimental monoclonal antibodies which are being studied for the treatment of cancer and other diseases. Bacteria have also been altered to break down oil slicks and industrial waste products. Plants and foods with such desired qualities as prolonged shelf life or increased resistance to diseases and pests have been created through genetic engineering; that is, by inserting DNA from other organisms. Much of the corn and soybeans grown in the United States, for example, are now genetically modified in some way. Livestock have also been genetically altered to produce medically useful substances. The field of biotechnology also includes gene therapy, in which attempts are made to insert normal or genetically altered genes into cells to treat genetic disorders and chronic diseases. Dairying is a business of producing, processing, and distributing milk and milk products. Ninety percent of the world's milk is obtained from cows; the remainder comes from goats, buffaloes, sheep, reindeer, yaks, and other ruminants. In the United States, dairy products account for nearly 16% of the food consumed annually. California, Wisconsin, New York, Pennsylvania, and Minnesota are the top five dairy states. About 17% of the milk produced is made into butter, 35%–40% is sold as beverage milk, and the remainder is devoted to farm uses and the making of cheese, concentrated milks, ice cream, dried milk solids (e.g. lactose and casein), yogurt and sour cream, and other processed products. About 60% of total beverage milk sold is low-fat or skim milk, which surpassed whole milk in sales in 1987. The development of modern dairying, which began around 1850, has been driven by the growth of urban markets and by scientific, technological, and economic factors: the invention of specialized machines, notably the cream separator; research in chemistry, physics, and bacteriology; the discovery of pasteriuzation; the introduction of the test devised by American agricultural chemist S. M. Babcock for determining the fat content of milk; improved refrigeration and transportation; the discovery of new uses for the byproducts of milk processing; and increased milk productivity. Traditional small-scale dairy farms have increasingly been replaced by larger operations with herds of 1,000 cows or more. Вiotechnology is often used to refer to genetic engineering technology of the 21st century, however the term encompasses a wider range and history of procedures for modifying biological organisms according to the needs of humanity, going back to the initial modifications of native plants into improved food crops through artificial selection and hybridization. Bioengineering is the science upon which all biotechnological applications are based. With the development of new approaches and modern techniques, traditional biotechnology industries are also acquiring new horizons enabling them to improve the quality of their products and increase the productivity of their systems. Before 1971, the term biotechnology was primarily used in the food processing and agriculture industries. Since the 1970s, it began to be used by the Western scientific establishment to refer to laboratory-based techniques being developed in biological research, such as recombinant DNA or tissue culture-based processes, or horizontal gene transfer in living plants, using vectors such as the Agrobacterium bacteria to transfer DNA into a host organism. In fact, the term should be used in a much broader sense to describe the whole range of methods, both ancient and modern, used to manipulate organic materials to reach the demands of food production. So the term could be defined as, "The application of indigenous and/or scientific knowledge to the management of (parts of) microorganisms, or of cells and tissues of higher organisms, so that these supply goods and services of use to the food industry and its consumers. Biotechnology combines disciplines like genetics, molecular biology, biochemistry, embryology and cell biology, which are in turn linked to practical disciplines like chemical engineering, information technology, and robotics. Patho-biotechnology describes the exploitation of pathogens or pathogen derived compounds for beneficial effect. Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non food (industrial) uses of crops and other products (e.g. biodegradable plastics, vegetable oil), and environmental uses. For example, one application of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer and milk products). Another example is using naturally present bacteria by the mining industry in bioleaching. Biotechnology is also used to recycle, clean up sites contaminated by industrial activities (bioremediation), and also to produce biological weapons.

The food processing industry utilizes these processes. Food processing often takes clean, harvested or slaughtered and butchered components and uses these to produce attractive and marketable food products. Similar processes are used to produce animal feed. Common food processing techniques include: Removal of unwanted outer layers, such as potato peeling or the skinning of peaches Chopping or slicing ,e.g. diced carrots. Mincing and macerating Liquefaction, such as to produce fruit juice Fermentation e.g. in beer breweries Emulsification Cooking, such as boiling, broiling, frying, steaming or grilling Deep frying Baking Mixing Addition of gas such as air entrainment for bread or gasification of soft drinks Proofing Spray drying Pasteurization Extreme examples of food processing include the delicate preparation of deadly fugu fish or preparing space food for consumption under zero gravity.

Retell the text. Food technology Vocabulary of the text Food technology – технология продуктов питания Packaging - упаковывание Wholesome food – полезная, здоровая пища Makeup of food – состав пищи Array – масса, множество Impact – влияние, воздействие Spoilage - порча Souring – прокисание, заквашивание Aseptically - асептически Solvent - растворитель Sophisticated – сложный, утончённый Food technology, or Food tech for short is the application of food science to the selection, preservation, processing, packaging, distribution, and use of safe, nutritious, and wholesome food. Food scientists and food technologists study the physical, microbiological, and chemical makeup of food. Depending on their area of specialization, food scientists may develop ways to process, preserve, package, or store food, according to industry and government specifications and regulations. Consumers seldom think of the vast array of foods and the research and development that has resulted in the means to deliver tasty, nutritious, safe, and convenient foods. In some schools, food technology is part of the curriculum and teaches, alongside how to cook, nutrition and the food manufacturing process. Research in the field now known as food technology has been conducted for decades. Nicolas Appert’s development in 1810 of the canning process was a decisive event. The process wasn’t called canning then and Appert did not really know the principle on which his process worked, but canning has had a major impact on food preservation techniques. Louis Pasteur's research on the spoilage of wine and his description of how to avoid spoilage in 1864 was an early attempt to put food technology on a scientific basis. Besides research into wine spoilage, Pasteur did research on the production of alcohol, vinegar, wines and beer, and the souring of milk. He developed pasteurization—the process of heating milk and milk products to destroy food spoilage and disease-producing organisms. In his research into food technology, Pasteur became the pioneer into bacteriology and of modern preventive medicine. By 1945, the original four departments that had taught the subject under different names (including those at the University of Massachusetts and the University of California) had been retitled "food science", "food science and technology", or a similar variant. The founding of the Institute of Food Technologists in 1939 has led to the general use of the term “food technologist.” Several companies in the food industry have played a role in the development of food technology. These developments have contributed greatly to the food supply. Some of these developments are: Instantized Milk Powder - D.D. Peebles (U.S. patent 2,835,586) developed the first instant milk powder, which has become the basis for a variety of new products that are rehydratable in cold water or milk. This process increases the surface area of the powdered product by partially rehydrating spray-dried milk powder. Freeze Drying - The first application of freeze drying was most likely in the pharmaceutical industry; however, a successful large-scale industrial application of the process was the development of continuous freeze drying of coffee. High-Temperature Short Time Processing - These processes for the most part are characterized by rapid heating and cooling, holding for a short time at a relatively high temperature and filling aseptically into sterilisation (microbiology) sterile containers. Decaffeination of Coffee and Tea - Decaffeinated coffee and tea was first developed on a commercial basis in Europe around 1900. The process is described in U.S. patent 897,763. Green coffee beans are treated with steam or water to around 20% moisture. The added water and heat separate the caffeine from the bean to its surface. Solvents are then used to remove the caffeine from the beans. In the 1980s, new non-organic solvent techniques have been developed for the decaffeination of coffee and tea. Carbon dioxide under supercritical conditions is one of these new techniques. U.S. patent 4,820,537 was issued to General Food Corp. for a CO2 decaffeination process. Process optimization- Food Technology now allows production of foods to be more efficient. Oil saving technologies are now available on different forms. Production methods and methodology have also become increasingly sophisticated. EXERCISES 1.

Give the summary of the text. Food chemistry Vocabulary of the text Food chemistry - химия продуктов питания Interaction - взаимодействие Poultry – домашняя птица Lettuce – салат-латук To enhance – увеличивать, повышать To encourage – поощрять, поддерживать Contamination – заражение Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavors, and colors. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut red delicious apples whether by hand or mechanical methods. Food chemistry's history dates back as far as the late 1700s when many famous chemists were involved in discovering chemicals important in foods, including Carl Wilhelm Scheele (isolated malic acid from apples in 1785), and Sir Humphry Davy (published the first ever book on agricultural and food chemistry in 1813 titled Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition. In 1874 the Society of Public Analysts was formed, with the aim of applying analytical methods to the benefit of the public. It's early experiments were based on bread, milk and wine. It was also out of concern for the quality of the food supply, mainly food adulteration and contamination issues that would first stem from intentional contamination to later with chemical food additives by the 1950s.

Food-Borne Illnesses Vocabulary of the text Food-Borne Illnesses – болезни, порождаемые пищей Harmful - вредный To cause - причинять, вызывать Mold – плесень, плесенный грибок Yeast – дрожжи, закваска Aerobe - аэроб Palatable – вкусный, аппетитный Manmade – искусственный, созданный руками человека Fungi – гриб, плесень Some microorganisms are harmful to the human body. Other microorganisms in food cause food to spoil. Three microorganisms that might cause food to spoil are bacteria, mold, and yeast. Growth of these organisms in food can be undesirable. Microorganisms, including bacteria, can be grouped according to their requirement for oxygen. Some grow only in the presence of oxygen (aerobes). Others grow only in the absence of oxygen (anaerobes). Some are able to grow with or without oxygen (facultative anaerobes). This is important in keeping food safe and palatable. Under natural conditions, anaerobes grow only in places protected from the air such as deep in the soil or under water. They can also grow under manmade anaerobic conditions, such as in canned or vacuum-packed foods which have not been processed or handled properly. Most bacteria can be killed with heat; therefore, boiling water will often make food safe to eat. Some strains, however, are so resistant to heat that they are only killed with very high temperatures. A food-borne illness is simply a sickness a person gets from eating contaminated food. Many contaminants are in the form of a harmful bacteria being present. Food intoxications are food- borne illnesses that come from consuming foods which contain toxins or poisons. Food infections are food-borne illnesses caused by eating food which has organisms that grow and cause illness after they enter the human body. Some of these are caused by molds and other fungi. EXERCISES 1. Answer the questions: 1) Can some microorganisms in food cause food to spoil? 2) What microorganisms cause food to spoil? 3) What are aerobes, anaerobes and facultative anaerobes? 4) Under what conditions can anaerobes grow? 5) How can bacteria be killed? 6) What is a food-borne illness? 7) What are food infections? 2.

Speak on the following topics: 1) Mold. 2) Fungi. 3) Yeast. Food additives Vocabulary of the text Food additives пищевые добавки To enhance увеличивать, усиливать, повышать, усугублять Flavouring приправа Abundance изобилие, избыток, множество Sweetener подсластитель Coloring краситель Dye краска, красящее вещество, краситель To hinder мешать, препятствовать, быть помехой Awareness сознание, знание, осведомлённость To be vocal высказывать открыто Food additives are substances added to foods by manufacturers to prevent spoilage or to enhance appearance, taste, texture, or nutritive value. By quantity, the most common food additives are flavorings, which include spices, vinegar, synthetic flavors, and, in the greatest abundance, sweeteners (e.g., sucrose, corn syrup, fructose, and dextrose). Colorings are another type of additive. Most colorings are synthetic dyes, but some (e.g., chlorophyll, beta carotene, and caramel) are naturally formed chemicals. Preservatives are divided into antioxidants, such as BHT, BHA, and ascorbic acid, which help prevent fats and oils from turning rancid or fruit from spoiling, and antimicrobial agents, which hinder the growth of mold and bacteria. Additives that help produce a desired texture include emulsifiers, which keep substances such as mayonnaise from separating, and stabilizers, including gelatin, pectin, and carrageenan, which prevent the formation of ice crystals in ice cream. Other food additives include nutrients, yeast and baking soda. Food additives comprise approximately 10% (about 150 lbs) of the food consumed by the average American adult. As nutritional awareness grows, many health experts and consumers have become more vocal in their criticism of the excessive and potentially dangerous use of food additives, particularly food colorings. EXERCISES 1. Answer the questions: 1. What are food additives? 2. Can you enumerate the most common food additives? 3. Most colorings are synthetic dyes, aren’t they? 4.

Find the information: 1. Flavorings. 2. Sweeteners. 3. Colorings. 4. Preservatives. 5. Emulsifiers. 6. Stabilizers. 7. Nutrients, yeast and baking soda. Food spoilage Vocabulary of the text Spoilage порча Unattractive непривлекательный Maturity зрелость, завершённость And so forth и так далее Perishable скоропортящийся Staple основной To lessen уменьшить Desirability желательность Tо alter изменить All foods are subjects to spoilage, the extent of which depends upon a number of factors. Among environmental factors affecting keeping quality are the temperature and humidity at which the food is held; whether the food has been frozen,heated or dried; and the particular nature of the food itself, its composition or structure. A food thought fit to eat by one person may be quite unattractive to another. In general, acceptability of food is determined by its state of development or maturity, absence of contamination in processing, and presence or absence of microbial or enzymatic action. Causes of spoilage may be microorganisms, insects, enzyme activity, natural metabolic reactions and environmental effects, such as freezing, burning, drying, oxidation and so forth. A three-part food-spoilage classification may be set up as follows: relatively stable, protectable and perishable. Staple foods are relatively stable: they do not perish or spoil unless handled carelessly. These foods include sugar, flour, cereal grains and dry beans. Protectable or semiperishable foods remain unspoiled for fairly long periods with proper care. These are potatoes, certain varieties of apples, onions, dried fruits and other dehydrated foods. Perishable foods spoil readily without special preservative methods. To this class belong meats, fish, most fruits, vegetables, poultry, eggs,milk and milk products. Spoilage is any change in the natural state of the food that lessens its desirability, either for aesthetic or health reasons. In general, these changes are of biological nature brought about by growth of microorganisms. In some cases changes result from oxidation. These factors may act alone or in combination. Microorganisms may synthesize compounds that alter the flavor, color, or odor of the food. EXERCISES 1. Answer the questions: 1. What does the extent of food spoilage depend upon? 2.

Food science Vocabulary of the text Food science – наука о пище Interdisciplinary - междисциплинарный Food safety – безопаснось пищи Sensory analysis – сенсорный анализ Molecular gastronomy – молекулярная гастрономия Food science is a discipline concerned with all technical aspects of food, beginning with harvesting or slaughtering, and ending with its cooking and consumption. Examples of the activities of food scientists include the development of new food products, design of processes to produce these foods, choice of packaging materials, shelf-life studies, sensory evaluation of the product with trained expert panels or potential consumers, as well as microbiological and chemical testing. Food scientists at universities may study more fundamental phenomena that are directly linked to the production of particular food product and its properties. Food science is a highly interdisciplinary applied science. It incorporates concepts from many different fields including microbiology, chemical engineering, biochemistry, and many others. Some of the subdisciplines of food science include: Food safety - the causes, prevention and communication dealing with food borne illness Food microbiology - the positive and negative interactions between micro-organisms and foods Food preservation - the causes and prevention of quality degradation Food engineering - the industrial processes used to manufacture food Product development - the invention of new food products Sensory analysis - the study of how food is perceived by the consumer's senses Food chemistry - the molecular composition of food and the involvement of these molecules in chemical reactions Food packaging - the study of how food is packaged to preserve the food after it has been processed. Molecular gastronomy - the scientific investigation of processes in cooking, social & gastronomical phenomena Food physics - the physical aspects of foods (such as viscosity, texture...) EXERCISES 1.

Food quality Vocabulary of the text Food quality – качество пищи Acceptable – приемлемый, допустимый External factors – внешние факторы Gloss – внешний блеск Susceptible – впечатлительный, восприимчивый To rely on – полагаться на Food quality is the quality characteristics of food that is acceptable to consumers. This includes external factors as appearance (size, shape, colour, gloss, and consistency), texture, and flavour; factors such as federal grade standards (e.g. of eggs) and internal (chemical, physical, microbial). Food quality is an important food manufacturing requirement, because food consumers are susceptible to any form of contamination that may occur during the manufacturing process. Many consumers also rely on manufacturing and processing standards, particularly to know what ingredients are present, due to dietary, nutritional requirements (vegetarian), or medical conditions (e.g., diabetes, or allergies). Besides ingredient quality, there are also sanitation requirements. It is important to ensure that the food-processing environment is as clean as possible in order to produce the safest possible food for the consumer. EXERCISES 1. Answer the questions: 1) What is food quality? 2) Do you know the external factors of characteristics of food? 3) Why is food quality an important food manufacturing requirement? 4) What do many consumers rely on? 2.

Food packaging Vocabulary of the text Food packaging – упаковывание продуктов питания Enclosing – окружение, заключение Containment - содержание Sealing system – система запечатывания Durability – прочность, стойкость, продолжительность срока службы Abrasion – стирание, снашивание Ultraviolet light – ультрафиолетовый свет Trauma - травма Wrapper - бандероль Flexibility - гибкость Throughput – пропускная способность, производительность Food packaging is the enclosing of food that requires protection from physical, chemical or biological influence. It also shows any nutrition information on the food being consumed. Food packaging's functions are as diverse as they are important. They are broken down as follows. Containment. For items that are granulated, paper-based packages are the best with a sealing system to prevent moisture infiltration of the product. Other products are packaged using metal cans, plastic bags and bottles. Another factor in containment is packaging durability, meaning the packaged food has to survive transport from the packaging at the food processing facility to the supermarket to the home for the consumer. Protection. The packaging must protect the food from biological agents in rats, insects, and microbes; from mechanical damage such as abrasion, compressive forces, and vibration; and from chemical degradation such as oxidation, moisture transfer, and ultraviolet light. Communication. Packaged food must be identified for consumer use mainly with label text and graphics. It can also be shown with the food package's shape such as the Coca-Cola bottle. Other well-known food package shapes include the potato chip bags and milk bottles. Functionality.The package must be easy to use for both manufacturers and consumers. These products can be purchased all at once such as frozen pizza. Another use may be to see if the package can go through a microwave process. Environmental issues. This means that we must reuse the packaging and reduce the size of the packaging. Package safety. Packing must be safe for products and the consumer. It should not render harmful influence on food and put traumas to the consumer. Food packaging types Packaging type Type container of Food examples Aseptic packages Primary whole eggs Plastic trays Primary Portion of fish Primary Potato chips Bags Boxes Cans Secondary Primary Box of Coca-Cola Can of Tomato soup. Flexible packaging Pallets Wrapper s Primary Bagged salad Tertiary A series of boxes on a single pallet used to transport from the manufacturing plant to a distribution center. Tertiary Serves to wrap the boxes on the pallet for transport Primary packaging is the main package that holds the food that is being processed. Secondary packaging combines the primary packages into one box being made. Tertiary packaging combines all of the secondary packages into one pallet. There are also special containers that combine different technologies for maximum durability: Bags-In-Boxes (used for soft drink syrup, other liquid products, and meat products) Wine box (used for wine) A choice of packaging machinery includes technical capabilities, labor requirements, worker safety, maintainability, serviceability, reliability, ability to integrate into the packaging line, capital cost, floor space, flexibility (change-over, materials, etc.), energy usage, quality of outgoing packages, qualifications (for food, pharmaceuticals, etc.), throughput, efficiency, productivity, ergonomics, etc. EXERCISES 1.

Food Substance Vocabulary of the text вещество To be composed of состоять из Item каждый отдельный предмет (в списке), пункт, вопрос Origin происхождение Ambient окружающий, обтекающий Gastronomy кулинария, гастрономия To diversify разнообразить To excrete выделять, извергать Spinach шпинат Inflorescence vegetables цветочные овощи Scarcity недостаток, нехватка, дефицит Civet виверра, циветта, цибетин Slaughter убой скота Evisceration потрошение Constraint принуждение, напряжение, скованность Myriad несметное число, десять тысяч, бесчисленный, несметный Pottery гончарные изделия, керамика, гончарное дело Food is any substance, usually composed primarily of carbohydrates, fats, water and/or proteins, that can be eaten or drunk by an animal or human being for nutrition or pleasure. Items considered food may be sourced from plants, animals or other categories such as fungus or fermented products like alcohol. Although many human cultures sought food items through hunting and gathering, today most cultures use farming, ranching, and fishing, with hunting, foraging and other methods of a local nature included but playing a minor role. Most traditions have a recognizable cuisine, a specific set of cooking traditions, preferences, and practices, the study of which is known as gastronomy. Many cultures have diversified their foods by means of preparation, cooking methods and manufacturing. This also includes a complex food trade which helps the cultures to economically survive by-way-of food, not just by consumption. Many cultures study the dietary analysis of food habits. While humans are omnivores, religion and social constructs such as morality often affect which foods they will consume. Food safety is also a concern with foodborne illness claiming many lives each year. In many languages, food is often used metaphorically or figuratively, as in "food for thought". Almost all foods are of plant or animal origin, although there are some exceptions. Foods not coming from animal or plant sources include various edible fungi, including mushrooms. Fungi and ambient bacteria are used in the preparation of fermented and pickled foods such as leavened bread, wine, beer, cheese, pickles, and yogurt. Many cultures eat seaweed, which is a protist, or blue-green algae (cyanobacteria) such as Spirulina. Additionally, salt is often eaten as a flavoring or preservative, and baking soda is used in food preparation. Both of these are inorganic substances, as is water, an important part of human diet. Many plants or plant parts are eaten as food. There are around 2,000 plant species which are cultivated for food, and many have several distinct cultivars. Plant-based foods can be classified as with the nutrients necessary for the plant's initial growth. Because of this, seeds are often packed with energy, and are good sources of food for animals, including humans. In fact, the majority of all foods consumed by human beings are seeds. These include cereals (such as maize, wheat, and rice), legumes (such as beans, peas, and lentils), and nuts. Oilseeds are often pressed to produce rich oils, including sunflower, rape (including canola oil), and sesame. Fruits are the ripened extensions of plants, including the seeds within. Fruits are made attractive to animals so that animals will eat the fruits and excrete the seeds over long distances. Fruits, therefore, make up a significant part of the diets of most cultures. Some fruits, such as pumpkin and eggplant, are eaten as vegetables. Vegetables are a second type of plant matter eaten as food. These include root vegetables (such as potatoes and carrots), leaf vegetables (such as spinach and lettuce), stem vegetables (such as bamboo shoots and asparagus), and inflorescence vegetables (such as globe artichokes and broccoli). Many herbs and spices are highly-flavorful vegetables. Animals can be used as food either directly, or indirectly by the products they produce. Meat is an example of a direct product taken from an animal, which comes from either muscle systems or from organs. Food products produced by animals include milk produced by mammals, which in many cultures is drunk or processed into dairy products such as cheese or butter. In addition birds and other animals lay eggs, which are often eaten, and bees produce honey, a popular sweetener in many cultures. Some cultures consume blood, some in the form of blood sausage, as a thickener for sauces, a cured salted form for times of food scarcity, and others use blood in stews such as civet. Food is traditionally obtained through farming, ranching, and fishing, with hunting, foraging and other methods of subsistence locally important. More recently, there has been a growing trend towards more sustainable agricultural practices. This approach, which is partly fueled by consumer demand, encourages biodiversity, local self-reliance and organic farming methods. Major influences on food production are international organizations, (e.g. the World Trade Organization and Common Agricultural Policy), national government policy (or law), and war. While some food can be eaten raw, many foods undergo some form of preparation for reasons of safety, palatability, or flavor. At the simplest level this may involve washing, cutting, trimming or adding other foods or ingredients, such as spices. It may also involve mixing, heating or cooling, pressure cooking, fermentation, or combination with other food. At home, most food preparation takes place in a kitchen. Some preparation is done to enhance the taste or aesthetic appeal; other preparation may help to preserve the food; and others may be involved in cultural identity. A meal is made up of food which is prepared to be eaten at a specific time and place. The preparation of animal-based food will usually involve slaughter, evisceration, hanging, portioning and rendering. In developed countries, this is usually done outside the home in slaughterhouses which are used to process animals en mass for meat production. Many countries regulate their slaughterhouses by law. For example the United States has established the Humane Slaughter Act of 1958, which requires that an animal be stunned before killing. This act, like those in many countries, exempts slaughter in accordance to religious law, such as kosher shechita and dhabiha halal. Strict interpretations of kashrut require the animal to be fully aware when its carotid artery is cut. On the local level a butcher may commonly break down larger animal meat into smaller manageable cuts and pre-wrapped for commercial sale or wrapped to order in butcher paper. In addition fish and seafood may be fabricated into smaller cuts by a fish monger at the local level. However fish butchery may be done on board a fishing vessel and quick-froze for preservation of quality. The term "cooking" encompasses a vast range of methods, tools and combinations of ingredients to improve the flavor or digestibility of food. Cooking technique, known as culinary art, generally requires the selection, measurement and combining of ingredients in an ordered procedure in an effort to achieve the desired result. Constraints on success include the variability of ingredients, ambient conditions, tools, and the skill of the individual cooking. The diversity of cooking worldwide is a reflection of the myriad nutritional, aesthetic, agricultural, economic, cultural and religious considerations that impact upon it. Cooking requires applying heat to a food which usually, though not always, chemically transforms it, thus changing its flavor, texture, appearance, and nutritional properties. Cooking proper, as opposed to roasting, requires the boiling of water in a container, and was practiced at least since the 10th millennium BC with the introduction of pottery. There is archaeological evidence of roasted foodstuffs at Homo erectus campsites dating from 420,000 years ago. EXERCISES 1. Answer the questions: 1. What is food? 2.

Fermentation is achieved by somewhat different chemical sequences in different species of organisms. Two closely related paths of fermentation predominate for glucose. When muscle tissue receives sufficient oxygen supply, it fully metabolizes its fuel glucose to water and carbon dioxide. However, at times of strenuous activity, muscle tissue uses oxygen faster than the blood can supply it. During this anaerobic condition, the six-carbon glucose molecule is only partly broken down to two molecules of the three-carbon sugar called lactic acid. This process, called lactic acid fermentation, also occurs in many microorganisms and in the cells of most higher animals. In alcoholic fermentation, such as occurs in brewer's yeast and some bacteria, the production of lactic acid is bypassed, and the glucose molecule is degraded to two molecules of the two-carbon alcohol, ethanol, and to two molecules of carbon dioxide. Many of the enzymes of lactic acid and alcoholic fermentation are identical to the enzymes that bring about the metabolic conversion known as glycolysis. Alcoholic fermentation is a process that was known to antiquity. Before 2000 B.C. the Egyptians apparently knew that crushed fruits stored in a warm place would produce a substance with a pleasant intoxicating power. By 1500 B.C. the production of beer from germinating cereals (malt) and the preparation of wines from crushed grapes were established arts in most of the Middle East. Aristotle believed that grape juice was an infantile form of wine and that fermentation was, therefore, the maturation of the grape extract. Interest in the process of fermentation has continued through the ages, and much of modern biochemistry, especially enzyme studies, has emerged directly from early studies on the fermentation process. One of the earliest laboratories established for the study of biological chemistry was founded in Copenhagen in 1875 and financed by the brewing family of Jacob Christian Jacobsen. EXERCISES 1.

Food adulteration Vocabulary of the text Аdulteration фальсификация, подделка, подмешивание To debase понижать качество, портить Admixture примесь Removal устранение, удаление Fraudulent обманный, мошеннический Standpoint точка зрения Welfare благосостояние, благоденствие To be superseded быть вытесненным, смещённым Rigorous строгий, точный, тщательный, скрупулёзный To be amended быть улучшенным, исправленным Food adulteration is the act of intentionally debasing the quality of food offered for sale either by the admixture or substitution of inferior substances or by the removal of some valuable ingredient. The Greek and Roman classics contain allusions to wine makers and dealers who colored and flavored their wine. In England as early as the 13th century, bakers cheapened their wares or scanted the weight, and lawmakers for the first time made an effort to prevent fraudulent dealings on the part of butchers and brewers. In Great Britain in the 18th and early 19th cent., coffee, tea, and cocoa were placed under protection laws by Parliament, passed not so much in the interest of the consumer as to keep up internal revenues. About the middle of the 19th cent. chemical and microscopal knowledge had reached the stage that food substances could be analyzed, and the subject of food adulteration began to be studied from the standpoint of the rights and welfare of the consumer. In 1860 the first food law framed in the interest of the purchaser was passed. That law, lacking sufficient means of enforcement, remained largely ineffective until 1872, when administrative officials were appointed and penalties for violation provided. In the United States the federal Food and Drug Act of 1906 was the result of a long and stormy campaign led by Dr. Harvey Washington Wiley. This law defined food adulteration and the misbranding of products; it provided regulations covering the interstate movement of food and penalties for violations. The act was superseded in 1938 by the more rigorous Food, Drug, and Cosmetic Act administered since 1940 by the Food and Drug Administration (now within the Dept. of Health and Human Services). It is charged with enforcing truthful and informative labeling of essential commodities, maintaining staff laboratories, and formulating definitions and standards promoting fair dealing in the interests of the consumer. The 1938 act broadened the definitions of adulteration, misbranding, and lack of informative labeling; it provided for factory inspections; and it increased the penalties for violations. It was amended in 1958 and 1962 to define and regulate food additives and food coloring. Imported goods that violate the provisions of the act may be denied admittance to the United States and if not removed within a given time may be destroyed. The federal law controls traffic from one state to another and is supplemented by local regulations that require food handlers to be licensed, thereby discouraging the spread of disease; it provides for the inspection by health officers of meat and other foods, of restaurants, and of dairies and cold storage methods.

PROTEINS Vocabulary of the text Protein - белок Organic compound – органическое соединение Amino acid - аминокислота Peptide bond- пептидная связь Enzyme - фермент Metabolism – обмен веществ Digestion - пищеварение Homogeneous – однородный, гомогенный Fibrous – волокнистый, жилистый, фиброзный Structural - структурный Functional - функциональный Tissue – ткань Gene- ген Genetic code- генетический код Nucleic acid- нуклеиновая кислота To catalyze-катализировать Axis- ось Helix- спираль, спиральная линия, винтовая линия Tertiary structure- третичная структура Ribosome- рибосома Chemical linkage- химическая связь Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups. The sequence of amino acids in a protein is defined by a gene and encoded in the genetic code. Proteins can also work together to achieve a particular function, and they often associate to form stable complexes. Like other biological macromolecules such as polysaccharides and nucleic acids, proteins are essential parts of organisms and participate in every process within cells. Many proteins are enzymes that catalyze biochemical reactions and are vital to metabolism. Proteins also have structural or mechanical functions, such as actin and myosin in muscle. Proteins are also necessary in animals' diets, since animals cannot synthesize all the amino acids they need and must obtain essential amino acids from food. Through the process of digestion, animals break down ingested protein into free amino acids that are then used in metabolism. The word protein comes from the Greek word πρώτα ("prota"), meaning "of primary importance." Proteins were first described and named by the Swedish chemist Jöns Jakob Berzelius in 1838. However, the central role of proteins in living organisms was not fully appreciated until 1926, when James B. Sumner showed that the enzyme urease was a protein. The first protein to be sequenced was insulin, by Frederick Sanger, who won the Nobel Prize for this achievement in 1958. The three-dimensional structures of both proteins were first determined by x-ray diffraction analysis; the structures of myoglobin and hemoglobin won the 1962 Nobel Prize in Chemistry for their discoverers. Protein is any of the group of highly complex organic compounds found in all living cells. Protein comprises approximately 50% of cellular dry weight. Hundreds of protein molecules have been isolated in pure, homogeneous form; many have been crystallized. All contain carbon, hydrogen, and oxygen, and nearly all contain sulfur as well. Some proteins also incorporate phosphorus, iron, zinc, and copper. Proteins are large molecules with high molecular weights (from about 10,000 for small ones [of 50–100 amino acids] to more than 1,000,000 for certain forms); they are composed of varying amounts of the same 20 amino acids, which in the intact protein are united through covalent chemical linkages called peptide bonds. The amino acids, linked together, form linear unbranched polymeric structures called polypeptide chains; such chains may contain hundreds of amino-acid residues; these are arranged in specific order for a given species of protein. Every protein molecule has a characteristic three-dimensional shape, or conformation. Fibrous proteins, such as collagen and keratin, consist of polypeptide chains arranged in roughly parallel fashion along a single linear axis, thus forming tough, usually water-insoluble, fibers or sheets. Globular proteins, e.g., many of the known enzymes, show a tightly folded structural geometry approximating the shape of an ellipsoid or sphere. Because the physiological activity of most proteins is closely linked to their three-dimensional architecture, specific terms are used to refer to different aspects of protein structure. The term “primary structure” denotes the precise linear sequence of amino acids that constitutes the polypeptide chain of the protein molecule. Automated techniques for amino-acid sequencing have made possible the determination of the primary structure of hundreds of proteins. The physical interaction of sequential amino-acid subunits results in a so-called secondary structure, which often can either be a twisting of the polypeptide chain approximating a linear helix (α-configuration), or a zigzag pattern (β-configuration). Most globular proteins also undergo extensive folding of the chain into a complex three-dimensional geometry designated as tertiary structure. Many globular protein molecules are easily crystallized and have been examined by X-ray diffraction, a technique that allows the visualization of the precise three-dimensional positioning of atoms in relation to each other in a crystal. The tertiary structure of several protein molecules has been determined from X-ray diffraction analysis. Two or more polypeptide chains that behave in many ways as a single structural and functional entity are said to exhibit quaternary structure. The separate chains are not linked through covalent chemical bonds but by weak forces of association. The precise three-dimensional structure of a protein molecule is referred to as its native state and appears, in almost all cases, to be required for proper biological function (especially for the enzymes). Structure of a protein is altered, e.g., by such physical factors as extremes of temperature, changes in pH, or variations in salt concentration, the protein is said to be denatured; it usually exhibits reduction or loss of biological activity. The cell's ability to synthesize protein is, in essence, the expression of its genetic makeup. Protein synthesis is a sequence of chemical reactions that occur in four distinct stages, i.e., activation of the amino acids that ultimately will be joined together by peptide bonds; initiation of the polypeptide chain at a cell organelle known as the ribosome; elongation of the polypeptide by stepwise addition of single amino acids to the chain; and termination of aminoacid additions and release of the completed protein from the ribosome. The information for the synthesis of specific amino-acid sequences is carried by a nucleic acid molecule called messenger RNA. Proteins are needed in the diet mainly for their amino acids. The mechanism of action of many widely used antibiotics, such as streptomycin, chloramphenicol, and tetracycline, can be understood in terms of their ability to interfere with some stage of protein synthesis in bacteria. Due to the chemical structure of the individual amino acids, the protein chain has directionality. The end of the protein with a free carboxyl group is known as the Cterminus or carboxyl terminus, whereas the end with a free amino group is known as the Nterminus or amino terminus. The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation. Structural proteins form most of the solid material in the human body. For example, the structural proteins keratin and collagen are the main component of your hair, muscles, tendons and skin. Functional proteins help carry out activities and functions in the human body. For example, hemoglobin is a functional protein that occurs in the red blood cells and helps to transport oxygen in the body. Myosin is a protein that occurs in muscle tissue and is responsible for the ability of muscles to contract. Insulin is a functional protein that helps regulate the storage of the sugar glucose in the human body. A subclass of the functional proteins is the group of polypeptides referred to as enzymes. Enzymes help to carry out specific chemical reactions in the body. Proteins are the building blocks of the body. That means every tissue is made of some form of protein. Even enzymes, antibodies, and hormones are proteins. Without a steady supply of new protein, we couldn't grow new cells. Our wounds would not heal. Worn-out cells could not be replaced. Protein can also be used for energy if the body doesn't get enough calories from carbohydrates and fats. Excess protein is changed to fat and stored. Meat, fish, poultry, dairy products, and eggs are good sources of protein. Grains, nuts, seeds, and legumes (dry peas and beans) also contain some protein. In food, proteins are essential for growth and survival and vary depending upon a person's age and physiology (e.g., pregnancy). Proteins in food are commonly found in peanuts, meat, poultry, and seafood. EXERCISES 1.

Fats are also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acids. The main purpose of fats in the body is to serve as a storage system and reserve supply of energy. During periods of low food consumption, fat reserves in the body can be mobilized and broken down to release energy. Fats serve as an insulation material to allow body heat to be conserved and fats line and protect delicate internal organs from physical damage. Fats in the diet can be converted to other lipids that serve as the main structural material in the membranes surrounding our cells. Fats are also used in the manufacture of some steroids and hormones that help regulate proper growth and maintenance of tissue in the body. Fats can be classified as either saturated or unsaturated depending on the structure of the long carbon-carbon chains in the fatty acids . Fats that contain no double bonds in their fatty acid chains are referred to as saturated fats. These fats tend to be solid at room temperature, such as butter or animal fat. The consumption of saturated fats carries some health risks in that they have been linked to atherosclerosis (hardening of the arteries) and heart disease. Some fatty acids have one or more double bonds between their carbon atoms. They are called unsaturated because they could hold more hydrogen atoms than they do. These fats are generally liquid at room temperature. Unsaturated fats can be either polyunsaturated (many double bonds) or monounsaturated fats (one or few double bonds). One system for naming unsaturated fatty acids is to indicate the position of the first double bond counting from the opposite end from the carboxyl group. That terminal carbon atom is called the omega carbon atom. Thus a monounsaturated fatty acid with its single double bond after carbon #3 is called an omega-3 fatty acid. Unsaturated fatty acids can exist in two different geometric forms. These are called the cis and trans forms. Unsaturated fatty acids exist naturally in the cis form. During food manufacturing processes these cis fatty acids may be changed to trans fatty acids. Hydrogenation of margarine causes this to occur. It has been suggested that trans fatty acids can increase the risk of heart disease. Free radicals are highly reactive molecules which have been linked to both heart disease and cancer. A number of factors, including alcohol, stress and environmental pollutants can increase the generation of free radicals in the body. Polyunsaturated fats can also generate free radicals, especially when exposed to heat or sunlight. Because of this it is suggested that vegetable oils should be stored out of direct sunlight. Mono-unsaturated olive oil is less vulnerable to free radical generation and so is a better choice for frying. Anti-oxidants such as vitamins A, C and E offer protection against free radicals. Fresh fruit and vegetables are rich in these anti-oxidants. Recent research suggests that the healthiest of the fats in the human diet are the monounsaturated fats, such as olive oil, because they appear to be beneficial in the fight against heart disease.Through their metabolism, plants generally produce triglycerides that contain unsaturated fatty acids such as peanut oil or olive oil, whereas animals generally produce triglycerides that contain saturated fatty acids which humans sometimes convert into butter and lard. Each fatty acid consists of a hydrocarbon chain with a carboxyl group at one end. The glycerol molecule has three hydroxyl groups, each able to interact with the carboxyl group of a fatty acid. Removal of a water molecule at each of the three positions forms a triglyceride. The three fatty acids in a single fat molecule may be all alike or they may be different. They may contain as few as 4 carbon atoms or as many as 24. Because fatty acids are synthesized from fragments containing two carbon atoms, the number of carbon atoms in the chain is almost always an even number. In animal fats, 16carbon (palmitic acid) and 18-carbon (stearic acid) fatty acids are the most common.Double bonds are rigid and those in natural fats introduce a kink in the molecule. This prevents the fatty acids from packing close together and as a result, unsaturated fats have a lower melting point than do saturated fats. Fats are the nutrients that supply the most energy-more than twice as much as carbohydrates. They also carry four important vitamins (A,D,E, and K) through the body and supply some fatty acids that are absolutely necessary for good health. The fat that is stored in the body protect us. Foods such as butter, margarine, oils, and salad dressings are easy to pick out as fats. But not all sources of fat are so obvious. Whole milk, cheeses, ice cream, meat, poultry, fish, nuts, seeds, avocados, olives, gravies, sauces, bakery foods, fried foods, and even some candies contain fats. The term lipid comprises a diverse range of molecules and to some extent is a catchall for relatively water-insoluble or nonpolar compounds of biological origin, including waxes, fatty acids (including essential fatty acids), fatty-acid derived phospholipids, sphingolipids, glycolipids and terpenoids, such as retinoids and steroids. Some lipids are linear aliphatic molecules, while others have ring structures. Some are aromatic, while others are not. Some are flexible, while others are rigid. Most lipids have some polar character in addition to being largely nonpolar. Generally, the bulk of their structure is nonpolar or hydrophobic ("water-fearing"), meaning that it does not interact well with polar solvents like water. Another part of their structure is polar or hydrophilic ("water-loving") and will tend to associate with polar solvents like water. This makes them amphiphilic molecules (having both hydrophobic and hydrophilic portions). Lipids in food include the oils of such grains as corn, soybean, from animal fats, and are parts of many foods such as milk, cheese, and meat. They also act as vitamin carriers. Waxes are similar to fats except that waxes are composed of only one long-chain fatty acid bonded to a long-chain alcohol group attached. Because of their long, nonpolar carbon chains, waxes are extremely hydrophobic ( they lack an affinity for water). Both plants and animals use this waterproofing characteristic as part of their composition. Plants most noticeably use waxes for a thin protective covering of stems and leaves to prevent water loss. Similarly, animals employ waxes for protective purposes; for instance, earwax in humans prevents foreign material from entering and possibly injuring the ear canal area. Phospholipids are similar to fats except they have two fatty acid chains bonded to a glycerol plus they contain the element phosphorus. Phospholipids are unique because they have a hydrophobic and a hydrophilic (water-soluble) end. Phospholipids are biologically important because they are the main structural components of cell membranes. The cell membrane is called a phospholipid bilayer because it consists of two phospholipid layers oriented so that the hydrophyllic “head” of both molecules face the exterior and the hydrophobic “tails” of both molecules create the interior of the membrane. Therefore, water and other cellular fluids are contained. The hydrophobic ends for both molecules face each other on the inside and allow for passage of acceptable, and some objectionable, materials through the cell membrane. Steroids are structurally different from the other lipids. The carbon skeleton of steroids is bent to form four fused rings that do not contain fatty acids. The most common steroid, cholesterol, is needed to make both the male (testosterone) and female (estrogen) sex hormones, and it is a component of cell membranes and is needed for the proper function of nerve cells. Excessive amounts of cholesterol, however, have been linked to heart disease. Another popular steroid group is the anabolic steroids that are man-made and mimic the effect of the male hormone, testosterone. Originally intended as a treatment for anemia and certain diseases that destroy muscle, athletes have recently been using them to increase muscle mass, stamina, and strength—which they will do. However, the performance-enhancement drugs come with a price. The anabolic steroids are linked to increased cholesterol levels, mood swings, reduced sex drive, possible infertility, and possible connections between liver damage and the resulting liver cancer. Certain beneficial fat-soluble hormones, such as cortisol, are also familiar steroids. EXERCISES 1. Answer the questions: 1. What are fats? 2.

Text B. Fat biological value Vocabulary of the text Cellular structure – клеточная структура Fat depot – жировое хранилище Availability – пригодность, наличие Irreplaceable –незаменимый, невосстановимый, невозместимый Daily consumption – суточное потребление To absorb energy – поглощать энергию Replenishment – повторное наполнение, пополнение To split - расщепляться Bile - жёлчь Digestibility - удобоваримость Combustion – горение, сгорание Ignition – воспламенение, вспышка Ghee – топлёное масло из молока буйволицы Lard – сало The role of fats in the diet is determined by their high calorie and protein together with the participation of plastic processes. Fat is a part of the cellular structures, often referred to as protoplazmatic or structural, as opposed to an emergency, or reserve, which accumulates in the body's so-called fat depots. In addition to the high caloric, fat biological value is determined by the availability of vitamins (A, D, E) and polyunsaturated fatty acids. Vitamins A and D are found in animal fat, especially a lot of them in the liver of fish and marine animals, vegetable oils prevail in vitamin E. Polyunsaturated fatty acids - linoleic and arachidonic - are irreplaceable because their synthesis in the body is severely limited. They serve an important role in the exchange of substances: lack of nutritional adversely affect the livelihood of the human body. Linoleic acid is up to 50% or more of all fatty acids in the vegetable oil. The most biologically useful fat content is 10% of polyunsaturated fatty acids, 30% of saturated fatty acids, 60% of oleic acid close to the bold-acid composition of pork lard, peanut and olive oil, and some margarine. The share of fats should account for about 30% of daily caloric diet rights, i.e., the daily consumption of fat with food should be 90-100 y. Given the needs of the organism in the polyunsaturated fatty acid 30% of fat should be consumed with vegetable oils and 70% of fatwith animal fats. Much attention is now being paid to fat substances - phospholipids, cholesterol and others which are actively involved in various vital body processes, The need for phospholipids is about 5 y. per day. in a significant number contained in fatty meats, egg yolks and other products. Cholesterol enters an organism with products of animal origin. By its calorie fat is almost 2 times better than carbohydrates. Fats should be used in quantities to fill most favorable energy costs. It is necessary, however, to note that the amount of fat in the diet is determined by different circumstances, which include the intensity of work, climatic conditions, and the age of people. Man taken by intense physical labor needs to eat more calorie foods, therefore, and the conditions in the north, requiring a large heat energy costs, also cause an increase in demand for fat. The more the body absorbs energy, the greater is the amount of fat needed for its replenishment. But we should not forget that excessive fat in the diet, even of a healthy person is harmful. Fats do not dissolve in water or in digestive juices. In the body, they split and emulsify, with the assistance of bile. Excess amount of fat violates the digestive process and raises the unpleasant feeling of heartburn. Excessive fat in the diet reduces its uptake, especially essential part of food - proteins. Nutritional value of various fats is not the same and depends largely on the digestibility of fat body. Digestible fat, in turn, depends on its melting temperature. Thus, the fat with low melting temperature not exceeding 370 (i.e., the temperature of the human body), has the potential to be the fullest and most rapidly emulsifying in the body and, therefore, most fully and easily digested. Fats with low melting temperature include butter, pork fat, goose fat, all kinds of margarines, and the liquid fat. Fats with a high melting point are learnt much worse. While butter is digested in the organism at 98.5%, sheep fat is digested only at 80-90%, beef fat, depending on the melting point, is at 80-94%. The value of fats in cooking is extremely high. One of the major cooking processes - hot – is usually conducted with the help of fats, the heat allows fat to fuel product to a high temperature without combustion and ignition. Forming a thin layer between the bottom and the roasted product, fat contributes to a more equitable warm. Thanks to the ability of dissolving some color and flavor substances derived from vegetables fat used to improve the appearance and smell of food. Choosing fat for cooking a dish, the chief must take into account not only the uptake of the body, which is especially important in the manufacture of dietary foods and baby food, but also how this fat reacts to strong heating. Not all fats can be warmed to a high temperature without decomposition, which is detected by the appearance of smoke. The temperature varies smoke. Butter, for example, can heat only until 2080. When it warms it decomposes and gives roast product unpleasant taste bitterness. Pork fat decomposition can be without heat until 2210, kitchen margarine until 2300. Kitchen margarine, moreover, contains a small amount of moisture, which makes them very convenient for frying different products. Ghee also does not withstand heat up to high temperatures. It can be used for frying only when there is no need to heat the product severely and the process of frying runs quickly. The choice of fat also depends on its consistency with the culinary flavoring product. All cooks know that the taste of food determine not only the basic product, but also fat used for cooking. Fat is not an appropriate dish to taste this, it can worsen. You can not, for example, produce sweet pancakes with preserve on beef or pork fat. Wrong selection of fat for cooking this dish is a violation of one of the basic laws of cooking, and only the inexperienced, inept cook uses fats outside their taste and conformity with the product. Butter is used mainly for sandwiches, as well as a number of ready-to jelly foods. You should not use butter for frying, especially because this oil contains up to 16% of moisture, so much shall be sprayed. Butter, in many cases, can change all kinds of table margarine. Animal fats - beef and pork fat - are used for hot meals and meat, roasting of certain types of flour product. Mutton's lard is successfully used in many dishes in Caucasian and Central Asian cuisine. Liquid fats, vegetable oils are used in all cases according to recipe calls for a fat. The use of different fat foods is often defined by its melting temperature For those foods that are served on a table, refractory fats are not suitable because they give unpleasant taste, as they say, "stay on lips." For these foods it is appropriate to use cow and vegetable oil, margarine, pork lard. Although margarine and pork lard are also firm, they quickly melt in the mouth and do not give dishes "tallow" taste. Currently it is believed that around 42% of energy in the typical British diet is from fat. Dietary advice is to reduce this. The COMA (Committee on Medical Aspects of Food Policy) reports that no more than 35% of daily energy requirement should come from fat while the NACNE (National Advisory Committee on Nutritional Education) paper recommends a reduction to no more than 30%. Special emphasis is placed on reducing the amount of saturated fat in the diet. Vegetarian diets tend to be lower in fat than omnivore diets. However, vegetarians consuming dairy products and processed foods high in fat may still be consuming too much. Advice to vegetarians is to keep fat intake to a minimum, avoid high fat dairy products and processed foods containing dairy fats and hydrogenated vegetable fats, and to use olive oil for cooking purposes.

Fats & Cholesterol Vocabulary of the text To keep tissues in good repair –сохранять ткани в хорошем состоянии Manufacture of hormones –производство гормонов Plant foods - продукты растительного происхождения Nerve function –нервная функция Arthritis - артрит Precursor – предшественник, предвестник Sunflower - подсолнечник Plaque – бляшка Too much fat is bad for us, but a little is necessary to keep our tissues in good repair, for the manufacture of hormones and to act as a carrier for some vitamins.Two of fatty acids, linoleic and linolenic acids, are termed essential as they must be provided in the diet. This is no problem as they are widely found in plant foods. Linoleic acid is converted into the body to arachidonic acid from which prostoglandins and other vital compounds are made. Because of this conversion, arachidonic acid is not an essential fatty acid as was once believed. ALinolenic acid is converted to eicosapentanoic acid (EPA) which is important in proper nerve function. EPA is present in fish oils and is claimed to be beneficial in reducing the symptoms of arthritis and the risk of heart disease. For this reason, fish oils are sometimes used therapeutically. Plant oils containing large amounts of a-linolenic acid can be used as an alternative by vegetarians. Linseeds and linseed oil are particularly rich sources of a-linolenic acid. A high intake of saturated fat can lead to a raised blood cholesterol level and this has been linked to heart disease. Vegetable fats tend to be more unsaturated and this is one of the benefits of a vegetarian diet. Mono-unsaturated fats, such as olive oil or peanut oil, are best used for frying as the poly-unsaturated fats, like sunflower or safflower oil are unstable at high temperatures. Animal fats (including butter and cheese) tend to be more saturated than vegetable fats, with the exception of palm oil and coconut oil. Cholesterol is present in animal foods but not plant foods. It is essential for metabolism but is not needed in the diet as our bodies can produce all that is needed. Raised blood cholesterol is associated with an increased risk of heart disease. Cholesterol belongs to the sterol group of fats. Cholesterol is essential as a component of cell membranes and a precursor of bile acids and certain hormones. The body can make its own cholesterol and so a dietary source is not required. Cholesterol is transported in to various proteins. These complex molecules are called lipoproteins. There are four main types of lipoprotein involved in cholesterol transport. The most commonly used types are low density lipoprotein (LDL) and high density lipoprotein (HDL). Cholesterol may form plaques on artery walls if levels in the blood are too high. This can lead to atherosclerosis. Because of this high blood cholesterol is linked with heart disease. It is the LDL cholesterol which has been linked to heart disease. HDL cholesterol may help protect against the risk of heart disease. The amount of dietary cholesterol is not clearly linked to levels of cholesterol in the blood. Blood cholesterol is more closely related to the amount of saturated fat in the diet, saturated fat raising blood cholesterol. Unsaturated fats are not thought to raise blood cholesterol and may indeed lower levels.

AMINO ACIDS Vocabulary of the text Organic compounds органические соединения Nourishment value питательная ценность To bind связывать, переплетать Release освобождение Intestinal tract пищеварительный тракт Bloodstream поток крови To suck from высасывать из Irreplaceable незаменимый, невосстановимый, невозместимый Array масса, множество Versatility многосторонность Aqueous водяной, водянистый Amino acids are organic compounds, which are fundamental component by the part of the proteins, and they contain carbon, hydrogen, oxygen, nitrogen. Amino acids determine the biological specificity of proteins and their food nourishment value. The disturbance of the exchange of amino acids is the reason for many illnesses. In nature more than 20 amino acids are discovered. Every amino acid except glycine can occur as either of two optically active stereoisomers, d or l; the more common isomer in nature is the l-form. When the carboxyl carbon atom of one amino acid covalently binds to the amino nitrogen atom of another amino acid with the release of a water molecule, a peptide bond is formed. Amino acids are released in the intestinal tract by the digestion of food proteins and are then carried in the bloodstream to the body cells, where they are used for growth, maintenance, and repair. Cellular catabolism breaks amino acids down into smaller fragments. Many of the amino acids necessary in metabolism can be synthesized in the human or animal body when needed; these are called nonessential. Others cannot be synthesized in sufficient quantities; these are termed essential and must be provided in the diet. Amino acids are sucked from the gastrointestinal tract and with the blood enter all organs and cloths, where they are used for the synthesis of proteins and undergo different changes. In the blood a constant concentration of amino acids is supported. In the muscles, the cloth of the brain and liver the content of free amino acids is many times higher than in the blood, and is less constant. Amino acid concentration in the blood makes it possible to judge the functional state of the liver and kidneys. The content of amino acids in the blood can noticeably increase with the disturbances of the function of kidneys, the feverish states, the diseases, connected with the increased content of protein. Amino acids are divided into 1) irreplaceable (valine, leucine, phenylalanine, isoleucine, methionine, tryptophan, threonine, lysine); 2) partially replaced (arginine and histidine); 3) replaced (alanine, asparagine, asparitic acid, glycine (glycocoll), serine, glutamine, proline, tyrosine, glutamic acid, cysteine (cystine). Irreplaceable amino acids are not synthesized in the human organism, but they are necessary for the normal vital activity. They must enter organism with the food. With a deficiency in the irreplaceable amino acids inhibits the growth itself and development of organism. The optimum content of irreplaceable amino acids in the food protein depends on the age, the profession of man, and also on other reasons. The replaceable amino acids are synthesized in the human organism. Amino acids are very small biomolecules with an average molecular weight of about 135 daltons. The 20 amino acids that are found within proteins convey a vast array of chemical versatility. Amino acid is a molecule that contains both amine and carboxyl functional groups. Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism. Protein substances make up the muscles, tendons, organs, glands, nails, and hair. Amino acid side chains can be polar, non-polar, or practically neutral. Polar side chains tend to be present on the surface of a protein where they can interact with the aqueous environment found in cells. On the other hand, non-polar amino acids tend to reside within the center of the protein where they can interact with similar non-polar neighbors. EXERCISES 1) 1) 2) 3) isn’t it?

Various pesticides are known as insecticides, fungicides, herbicides, and rodenticides, i.e., agents primarily effective against insects, nematodes (or roundworms), fungi, weeds, and rodents, respectively. Pesticides can be derived from plants (e.g., pyrethrin, neem) or minerals, or they can be chemically manufactured (e.g., DDT, 2,4-D). Natural predators and other biological methods are also used. Among the biological agents, parasites and predators feed on pests, pathogens sicken them, and pheromones interfere with insect mating. There are also genetically engineered pesticides, such as the toxin-producing Bacillus thuringiensis strain used against moth larvae. Chemical pesticides are usually contact, stomach, or fumigant poisons. Contact poisons may have immediate or delayed effects after physical contact with a pest. Fumigants, which may initially have the form of a solid, liquid, or gas, kill pests while in a gaseous state. Some insecticides and fungicides are systemic, i.e., they are translocated by a plant from the area of application to other plant parts, where they affect only pests that feed on the crop. Nonselective pesticides can affect both the targeted pest and other organisms; selective pesticides affect only the target pest. Persistent pesticides are those that remain in the environment for a long time. In the environment, the biological concentration of chemical pesticides (the amount retained in an organism through direct contact or consumption of affected plants or animals) tends to increase the higher the animal is in the food chain. DDT, for example, severely reduced the rate of reproduction in many fish and birds. Chemical pesticides now undergo exhaustive and expensive trials prior to government registration and release. The carcinogenicity of some pesticide components, however, is a vigorously debated topic. Government testing often uses massive amounts of such substances on laboratory animals, creating what some critics feel is an exaggerated assessment of their danger. Humans are heavily exposed to pesticides usually as a result of acute exposure, such as accidental inhalation, on the job. Potential dangers from pesticide use must be weighed against improved crop quality and yield and greatly improved human health around the world, as well as the availability of fresh fruits and vegetables that the use of pesticides has made possible. Nevertheless, many consumers are concerned about the effects of pesticide residues in foods, especially for infants, whose systems may not be able to convert toxic chemicals into harmless substances as readily as adult systems can.

Carbohydrates Vocabulary of the text Carbohydrate - углевод Starch - крахмал Cellulose -целлюлоза To supply energy – снабжать энергией Polymeric compound – полимерное соединение To yield – производить, поддаваться Energy source – источник энергии Organic molecule – органическая молекула Ratio – отношение, пропорция, коэффициент, соотношение Photosynthesis - фотосинтез Soluble -растворимый Hydroxyl group –гидроксильная группа Refined sugar – сахар-рафинад Lollilop – леденец на палочке To store glucose – запасать глюкозу Seeds – семена, зёрна Bean – боб, фасоль Salive - слюна Intestines - кишки Bloodstream – поток крови Stiff – жёсткий, густой Fiber – волокно, фибра Digestive system – пищеварительная система To overeat - переедать Carbohydrate is any member of a large class of chemical compounds that includes sugars, starches, cellulose, and related compounds. These compounds are produced naturally by green plants from carbon dioxide and water. Carbohydrates are important as foods; they supply energy and are used in the production of fats. They are also used in various forms in industry and commerce. There are three main classes of carbohydrates. Monosaccharides are the simple sugars, e.g., fructose and glucose; they have the general formula (CH2O)n, in which n is an integer larger than 2. Dissaccharides include lactose, maltose, and sucrose. Upon hydrolysis, a disaccharide molecule yields two monosaccharide molecules. Most disaccharides have the general formula Cn(H2O)n-1, with n larger than 5. Polysaccharides include such substances as cellulose, dextrin, glycogen, and starch; they are polymeric compounds made up of the simple sugars and can be hydrolyzed to yield simple sugars. The disaccharides are sometimes grouped with the simpler polysaccharides (usually those made up of three or four simple sugar units) to form a class of carbohydrates called the oligosaccharides. Carbohydrates are the main energy source for the human body. Chemically, carbohydrates are organic molecules in which carbon, hydrogen, and oxygen bond together in the ratio: Cx(H2O)y, where x and y are whole numbers that differ depending on the specific carbohydrate to which we are referring. Animals (including humans) break down carbohydrates during the process of metabolism to release energy. For example, the chemical metabolism of the sugar glucose is shown below C6H12O6 + 6 O2 6 CO2 + 6 H2O +energy Animals obtain carbohydrates by eating foods that contain them, for example potatoes, rice, breads, and so on. These carbohydrates are manufactured by plants during the process of photosynthesis. Plants harvest energy from sunlight to run the reaction just described in reverse: 6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2 A potato, for example, is primarily a chemical storage system containing glucose molecules manufactured during photosynthesis. In a potato, however, those glucose molecules are bound together in a long chain. As it turns out, there are two types of carbohydrates, the simple sugars and those carbohydrates that are made of long chains of sugars - the complex carbohydrates. All carbohydrates are made up of units of sugar (also called saccharide units). Carbohydrates that contain only one sugar unit (monosaccharides) or two sugar units (disaccharides) are referred to as simple sugars. Simple sugars are sweet in taste and are broken down quickly in the body to release energy. Two of the most common monosaccharides are glucose and fructose. Glucose is the primary form of sugar stored in the human body for energy. Fructose is the main sugar found in most fruits. Both glucose and fructose have the same chemical formula (C6H12O6); however, they have different structures, as shown (note: the carbon atoms that sit in the "corners" of the rings are not labeled): Glucose Fructose Disaccharides have two sugar units bonded together. For example, common table sugar is sucrose, a disaccharide that consists of a glucose unit bonded to a fructose unit. Glucose, galactose, and fructose are "single" sugars or monosaccharides. Two monosaccharides can be linked together to form a "double" sugar or disaccharide. There are three common disaccharides: sucrose — common table sugar = glucose + fructose lactose — major sugar in milk = glucose + galactose maltose — product of starch digestion = glucose + glucose Although the process of linking the two monomers is rather complex, the end result in each case is the loss of a hydrogen atom (H) from one of the monosaccharides and a hydroxyl group (OH) from the other. The resulting linkage between the sugars is called a glycosidic bond. The molecular formula of each of these disaccharides is C12H22O11 = 2 C6H12O6 − H2O .All sugars are very soluble in water because of their many hydroxyl groups. Sugars are the most important source of energy for many cells. Carbohydrates provide the bulk of the calories (4 kcal/gram) in most diets, and starches provide the bulk of that. Starches are polysaccharides. Simple carbohydrates are also called simple sugars. Simple sugars are found in refined sugars, like the white sugar you'd find in a sugar bowl. If you have a lollipop, you're eating simple carbohydrates. But you'll also find simple sugars in more nutritious foods, such as fruit and milk. It's better to get your simple sugars from food like fruit and milk. Why? Because they contain vitamins, fiber, and important nutrients like calcium. A lollipop does not. Complex carbohydrates are polymers of the simple sugars. In other words, the complex carbohydrates are long chains of simple sugar units bonded together (for this reason the complex carbohydrates are often referred to as polysaccharides). The potato we discussed earlier actually contains the complex carbohydrate starch. Starch is a polymer of the monosaccharide glucose: Starch is the principal polysaccharide used by plants to store glucose for later use as energy. Plants often store starch in seeds or other specialized organs; for example, common sources of starch include rice, beans, wheat, corn, potatoes, and so on. When humans eat starch, an enzyme that occurs in saliva and in the intestines called amylase breaks the bonds between the repeating glucose units, thus allowing the sugar to be absorbed into the bloodstream. Once absorbed into the bloodstream, the human body distributes glucose to the areas where it is needed for energy or stores it as its own special polymer - glycogen. Glycogen, another polymer of glucose, is the polysaccharide used by animals to store energy. Excess glucose is bonded together to form glycogen molecules, which the animal stores in the liver and muscle tissue as an "instant" source of energy. Both starch and glycogen are polymers of glucose; however, starch is a long, straight chain of glucose units, whereas glycogen is a branched chain of glucose units, as seen in the illustrations linked below: Another important polysaccharide is cellulose. Cellulose is yet a third polymer of the monosaccharide glucose. Cellulose differs from starch and glycogen because the glucose units form a two-dimensional structure, with hydrogen bonds holding together nearby polymers, thus giving the molecule added stability. Cellulose, also known as plant fiber, cannot be digested by human beings, therefore cellulose passes through the digestive tract without being absorbed into the body. Some animals, such as cows and termites, contain bacteria in their digestive tract that help them to digest cellulose. Cellulose is a relatively stiff material, and in plants cellulose is used as a structural molecule to add support to the leaves, stem, and other plant parts. Despite the fact that it cannot be used as an energy source in most animals, cellulose fiber is essential in the diet because it helps exercise the digestive track and keep it clean and healthy. Fiber is the complex carbohydrate that forms the tough cell walls in plants. Even though humans can't digest fiber, it is important because it helps keep food moving though the digestive tract. Fiber may also help keep the intestines in good working order. All plants supply some fiber, but whole grains, fruits, and vegetables are especially good sources. As with simple sugars, some complex carbohydrate foods are better choices than others. Refined grains, such as white flour and white rice, have been processed, which removes nutrients and fiber. But unrefined grains still contain these vitamins and minerals. Unrefined grains also are rich in fiber, which helps your digestive system work well. Fiber helps you feel full, so you are less likely to overeat these foods. That explains why a bowl of oatmeal fills you up better than sugary candy that has the same amount of calories as the oatmeal.So which type of carbs should you eat? Both can be part of a healthy diet. When you eat carbohydrates, the body breaks them down into simple sugars. These sugars are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy. When this process goes fast - as with simple sugars - you're more likely to feel hungry again soon. When it occurs more slowly, as with a whole-grain food, you'll be satisfied longer. These types of complex carbohydrates give you energy over a longer period of time. The carbohydrates in some foods (mostly those that contain a lot of simple sugars) cause the blood sugar level to rise more quickly than others. Scientists have been studying whether eating foods that cause big jumps in blood sugar may be related to health problems like diabetes and heart disease. You're probably already on the right track if you are limiting simple sugars (such as candy) and eating more complex carbohydrates (like vegetables, oatmeal, and whole-grain wheat bread). In many ways, our bodies can be thought of as chemical processing plants. Chemicals are taken in, processed through various types of reactions, and then distributed throughout the body to be used immediately or stored for later use. The chemicals used by the body can be divided into two broad categories: macronutrients, those substances that we need to eat regularly in fairly large quantities, and micronutrients, those substances that we need only in small amounts. Three major classes of macronutrients are essential to living organisms: carbohydrates, fats, and proteins. The main function of carbohydrates is to supply energy. That's a tall order because all 100 trillion cells in the body need a constant supply of fuel. Even when you don't think you are doing a thing, your heart is beating and your lungs are working. In fact, every organ is busy doing something. Approximately a pound of carbohydrate is stored in the liver in a form called glycogen. This glycogen is used when the body needs quick energy. Any other excess carbohydrate is converted to fat and stored as fatty tissue. EXERCISES 1.

Once considered a part of the plant kingdom, bacteria were eventually placed in a separate kingdom. Monera Bacteria fall into one of two groups, Archaebacteria (ancient forms thought to have evolved separately from other bacteria) and Eubacteria. A recently proposed system classifies the Archaebacteria, or archaea, and the Eubacteria as major groupings (sometimes called domains) above the kingdom level. Bacteria were the only form of life on earth for 2 billion years. They were first observed by Antony van Leeuwenhoek in the 17th cent.; bacteriology as an applied science began to develop in the late 19th cent. as a result of research in medicine and in fermentation processes, especially by Louis Pasteur and Robert Koch. Bacteria are remarkably adaptable to diverse environmental conditions: they are found in the bodies of all living organisms and on all parts of the earth—in land terrains and ocean depths, in arctic ice and glaciers, in hot springs, and even in the stratosphere. Our understanding of bacteria and their metabolic processes has been expanded by the discovery of species that can live only deep below the earth's surface and by species that thrive without sunlight in the high temperature and pressure near hydrothermal vents on the ocean floor. There are more bacteria, as separate individuals, than any other type of organism; there can be as many as 2.5 billion bacteria in one gram of fertile soil. EXERCISES 1. Answer the questions: 1.

Methods of food preservation Benign bacteria Rancidity Discolouration Pickling Sultanas Millet Rye Smoke-house To saponify Lye Vocabulary of the text благотворные бактерии прогорклость потеря цвета маринование кишмиш просо рожь коптильня омылять(ся) щёлок Food preservation is the process of treating and handling food in a way that preserves its value as food. The main effort is to stop or greatly slow down spoilage to prevent foodborne illness (e.g. salting, cooling, cooking). However some methods utilise benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g. cheese, wine). While maintaining or creating nutritional value, texture and flavour is important in preserving its value as food; this is a culturally dependent determinant as what qualifies as food fit for humans in one culture may not qualify in another culture. Preservation usually involves preventing the growth of bacteria, fungi and other microorganisms, as well as retarding the oxidation of fats which cause rancidity. It also includes processes to inhibit natural ageing and discolouration that can occur during food preparation such as the enzymatic browning reaction in apples which causes browning when apples are cut. Some preservation methods require the food to be sealed after treatment to prevent recontamination with microbes; others, such as drying, allow food to be stored without any special containment for long periods. Common methods of applying these processes include drying, spray drying, freeze drying, freezing,vacuum-packing, canning, preserving in syrup, sugar crystallisation, food irradiation, adding preservatives or inert gases such as carbon dioxide. Other methods that not only help to preserve food, but also add flavour, include pickling, salting, smoking, preserving in syrup or alcohol, sugar crystallisation and curing. Preservation processes include: Heating to kill or denature organisms (e.g. boiling) Oxidation (e.g use of sulphur dioxide) Toxic inhibition (e.g. smoking, use of carbon dioxide, vinegar, alcohol etc) Dehydration (drying) Osmotic inhibition ( e.g use of syrups) Low temperature inactivation (e.g. freezing) Ultra high water pressure (e.g. fresherized, a kind of “cold” pasteurization, the pressure kills naturally occurring pathogens, which cause food deterioration and affect food safety.) Chelation Drying One of the oldest methods of food preservation is by drying, which reduces water activity sufficiently to delay or prevent bacterial growth. Most types of meat can be dried. This is especially valuable in the case of pork, since it is difficult to keep without preservation. Many fruits can also be dried; for example, the process is often applied to apples, pears, bananas, mangoes, papaya, apricot, and coconut. Zante currants, sultanas and raisins are all forms of dried grapes. Drying is also the normal means of preservation for cereal grains such as wheat, maize, oats, barley, rice, millet and rye. Smoking Meat, fish and some other foods may be both preserved and flavoured through the use of smoke, typically in a smoke-house. The combination of heat to dry the food without cooking it, and the addition of the aromatic hydrocarbons from the smoke preserves the food. Freezing Freezing is also one of the most commonly used processes commercially and domestically for preserving a very wide range of food stuffs including prepared food stuffs which would not have required freezing in their unprepared state. For example, potato waffles are stored in the freezer, but potatoes themselves require only a cool dark place to ensure many months' storage. Cold stores provide large volume, long-term storage for strategic food stocks held in case of national emergency in many countries. Vacuum packing Vacuum packing stores food in a vacuum environment, usually in an air-tight bag or bottle. The vacuum environment strips bacteria of oxygen needed for survival, hence preventing the food from spoiling. Vacuum packing is commonly used for storing nuts. Salt Salting is curing draws moisture from the meat through a process of osmosis. Meat is cured with salt or sugar, or a combination of the two. Nitrates and nitrites are also often used to cure meat. Sugar Sugar is used to preserve fruits, either in syrup with fruit such as apples, pears, peaches, apricots, plums or in crystallized form where the preserved material is cooked in sugar to the point of crystallization and the resultant product is then stored dry. This method is used for the skins of citrus fruit (candied peel), angelica and ginger. A modification of this process produces glacé fruit such as glacé cherries where the fruit is preserved in sugar but is then extracted from the syrup and sold, the preservation is being maintained by the sugar content of the fruit and the superficial coating of syrup. The use of sugar is often combined with alcohol for preservation of luxury products such as fruit in brandy or other spirits. These should not be confused with fruit flavored spirits such as Cherry Brandy or Sloe gin. Pickling Pickling is a method of preserving food by placing it or cooking it in a substance that inhibits or kills bacteria and other microorganisms. This material must also be fit for human consumption. Typical pickling agents include brine (high in salt), vinegar, ethanol, and vegetable oil, especially olive oil but also many other oils. Most pickling processes also involve heating or boiling so that the food being preserved becomes saturated with the pickling agent. Frequently pickled items include vegetables such as cabbage (to make sauerkraut and curtido), peppers, and some animal products such as corned beef and eggs. EDTA may also be added to chelate calcium. Calcium is essential for bacterial growth. Lye Sodium hydroxide (lye) makes food too alkaline for bacterial growth. Lye will saponify fats in the food, which will change its flavor and texture. Lutefisk and hominy use lye in their preparation, as do some olive recipes. Canning and bottling Canning involves cooking fruits or vegetables, sealing them in sterile cans or jars, and boiling the containers to kill or weaken any remaining bacteria as a form of pasteurization. Various foods have varying degrees of natural protection against spoilage and may require that the final step occur in a pressure cooker. High-acid fruits like strawberries require no preservatives to can and only a short boiling cycle, whereas marginal fruits such as tomatoes require longer boiling and addition of other acidic elements. Many vegetables require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or microorganisms. Most such failures are rapidly detected as decomposition within the can causes gas production and the can will swell or burst. However, there have been examples of poor manufacture and poor hygiene allowing contamination of canned food by the obligate , Clostridium botulinum which produces an acute toxin within the food leading to severe illness or death. This organism produces no gas or obvious taste and remains undetected by taste or smell. Food contaminated in this way has included Corned beef and Tuna. Jellying Food may be preserved by cooking in a material that solidifies to form a gel. Such materials include gelatine, agar, maize flour and arrowroot flour. Some foods naturally form a protein gel when cooked such as eels and elvers, and sipunculid worms which are a delicacy in the town of Xiamen in Fujian province of the People's Republic of China. Jellied eels are a delicacy in the East End of London where they are eaten with mashed potatoes. Potted meats in aspic, (a gel made from gelatine and clarified meat broth) were a common way of serving meat off-cuts in the UK until the 1950s Jugging Meat can be preserved by jugging, the process of stewing the meat (commonly game or fish) in a covered earthenware jug or casserole. The animal to be jugged is usually cut into pieces, placed into a tightly-sealed jug with brine or gravy, and stewed. Red wine and/or the animal's own blood is sometimes added to the cooking liquid. Jugging was a popular method of preserving meat up until the middle of the 20th century. Irradiation Irradiation of food is the exposure of food to ionizing radiation; either high-energy electrons or X-rays from accelerators, or by gamma rays (emitted from radioactive sources as Cobalt-60 or Caesium-137). The treatment has a range of effects, including killing bacteria, molds and insect pests, reducing the ripening and spoiling of fruits, and at higher doses inducing sterility. The technology may be compared to pasteurization; it is sometimes called 'cold pasteurization', as the product is not heated. Irradiation is not effective against viruses or prions, it cannot eliminate toxins already formed by microorganisms, and is only useful for food of high initial quality. The radiation process is unrelated to nuclear energy, but it may use the radiation emitted from radioactive nuclides produced in nuclear reactors. Ionizing radiation is hazardous to life; for this reason irradiation facilities have a heavily shielded irradiation room where the process takes place. Radiation safety procedures ensure that neither the workers in such facility nor the environment receive any radiation dose from the facility. Irradiated food does not become radioactive, and national and international expert bodies have declared food irradiation as wholesome. However, opponents and consumer organizations dispute the wholesomeness of consuming such food. [3] National and international expert bodies have declared food irradiation as 'wholesome'; UN-organizations as WHO and FAO are endorsing to utilize food irradiation. International legislature’s opinion of whether food may be irradiated or not varies worldwide from no regulation to full banning. It is estimated that about 500,000 tons of food items are irradiated per year world-wide in over 40 countries. These are mainly spices and condiments with an increasing segment of fresh fruit irradiated for fruit fly quarantine. Modified atmosphere Modified atmosphere is a way to preserve food by operating on the atmosphere around it. Salad crops which are notoriously difficult to preserve are now being packaged in sealed bags with an atmosphere modified to reduce the oxygen (O2) concentration and increase the carbon dioxide (CO2) concentration. There is concern that although salad vegetables retain their appearance and texture in such conditions, this method of preservation may not retain nutrients, especially vitamins. Grains may be preserved using carbon dioxide. A block of dry ice is placed in the bottom and the can is filled with grain. The can is then "burped" of excess gas. The carbon dioxide from the sublimation of the dry ice prevents insects, mold, and oxidation from damaging the grain. Grain stored in this way can remain edible for five years. Nitrogen gas (N2) at concentrations of 98% or higher is also used effectively to kill insects in grain through hypoxia. However, carbon dioxide has an advantage in this respect as it kills organisms through both hypoxia and hypercarbia, requiring concentrations of only 80%, or so. This makes carbon dioxide preferable for fumigation in situations where an hermetic seal cannot be maintained. Burial in the ground Burial of food can preserve it due to a variety of factors: lack of light, lack of oxygen, cool temperatures, pH level, or desiccants in the soil. Many root vegetables are very resistant to spoilage and require no other preservation other than storage in cool dark conditions, for example by burial in the ground, such as in a storage clamp. Century eggs are created by placing eggs in alkaline mud (or other alkaline substance) resulting in their "inorganic" fermentation through raised pH instead of spoiling. The fermentation preserves them and breaks down some of the complex, less flavorful proteins and fats into simpler more flavorful ones. Most foods can be preserved in soil that is very dry and salty (thus a desiccant), or soil that is frozen. Cabbage was traditionally buried in the fall in northern farms in the USA for preservation. Some methods keep it crispy while other methods produce sauerkraut Sometimes meat is buried under conditions, which cause preservation. If buried on hot coals or ashes, the heat can kill pathogens, the dry ash can desiccate, and the earth can block oxygen and further contamination. If buried where the earth is very cold, the earth acts like a refrigerator. Fish (e.g. Gravlax) has been buried to preserve by fermentation. Controlled use of micro-organism Some foods, such as many cheeses, wines, and beers will keep for a long time because their production uses specific micro-organisms that combat spoilage from other less benign organisms. These micro-organisms keep pathogens in check by creating an environment toxic for themselves and other micro-organisms by producing acid or alcohol. Starter microorganisms, salt, hops, controlled (usually cool) temperatures, controlled (usually low) levels of oxygen and/or other methods are used to create the specific controlled conditions that will support the desirable organisms that produce food fit for human consumption. High pressure food preservation High pressure food preservation refers to high pressure used for food preservation. Pressed inside a vessel exerting 70,000 pounds per square inch or more, food can be processed so that it retains its fresh appearance, flavour, texture and nutrients while disabling harmful microorganisms and slowing spoilage. By 2001, adequate commercial equipment was developed so that by 2005 the process was being used for products ranging from orange juice to guacamole to deli meats and widely sold. EXERCISES 1.

The early American settlers dried foods such as corn, apple slices, currants, grapes, and meat. Compared with other methods, drying is quite simple. Dried foods keep well because the moisture content is so low that spoilage organisms cannot grow. Drying will never replace canning and freezing because these methods do a better job of retaining the taste, appearance, and nutritive value of fresh food. But drying is an excellent way to preserve foods that can add variety to meals and provide delicious, nutritious snacks. Recommended methods for canning and freezing have been determined by research and widespread experience. Food can be dried in several ways, for example, by the sun if the air is hot and dry enough, or in an oven or dryer if the climate is humid. Drying is not difficult, but it does take time and a lot of attention. Although there are different drying methods, the guidelines remain the same. Although solar drying is a popular and very inexpensive method. Dependable solar dehydration of foods requires 3 to 5 consecutive days when the temperature is 95 degrees. Speed For a good-quality product, vegetables and fruits must be prepared for drying as soon as possible after harvesting. They should be blanched, cooled, and laid out to dry without delay. Foods should be dried rapidly, but not so fast that the outside becomes hard before the moisture inside has a chance to evaporate. Drying must not be interrupted. Once you start drying the food, don't let it cool down in order to start drying again later. Mold and other spoilage organisms can grow on partly dried food. Temperature During the first part of the drying process, the air temperature can be relatively high, that is, 150 degrees to 160 degrees F. (65 degrees to 70 degrees C.), so that moisture can evaporate quickly from the food. Because food loses heat during rapid evaporation, the air temperature can be high without increasing the temperature of the food. But as soon as surface moisture is lost (the outside begins to feel dry) and the rate of evaporation slows down, the food warms up. The air temperature must then be reduced to about 140 degrees F. (60 degrees C.). Toward the end of the drying process the food can scorch easily, so you must watch it carefully. Each fruit and vegetable has a critical temperature above which a scorched taste develops. The temperature should be high enough to evaporate moisture from the food, but not high enough to cook the food. Carefully follow directions for regulating temperatures. Humidity and Ventilation Rapid dehydration is desirable. The higher the temperature and the lower the humidity, the more rapid the rate of dehydration will be. Humid air slows down evaporation. If drying takes place too fast, this means that the cells on the outside of the pieces of food give up moisture faster than the cells on the inside. Nutritive value Dried fruits are a good source of energy because they contain concentrated fruit sugars. Fruits also contain a rather large amount of vitamins and minerals. The drying process, however, destroys some of the vitamins, especially A and C. Exposing fruit to sulfur before drying helps retain vitamins A and C. Sulfur destroys thiamine, one of the B vitamins, but fruit is not an important source of thiamine anyway. Many dried fruits are rich in riboflavin and iron. Vegetables are a good source of minerals and the B vitamins thiamine, riboflavin, and niacin. Both fruits and vegetables provide useful amounts of the fiber (bulk) we need. Types of food to dry Many kinds of fresh fruits, vegetables, herbs, meat, and fish can be dried. If you have never tried drying food before, though, it's a good idea to experiment first by drying a small quantity in the oven. At the same time, you can become familiar with the drying process. Blanching Almost all vegetables need to be blanched (scalded in boiling water a short time before drying. Blanching stops the enzyme action, which drying cannot stop. If vegetables are not blanched, enzymes will destroy the color and flavor during drying and storage. A few vegetables such as mushrooms and onions do not need to be blanched before drying. Blanching also protects certain nutrients. Some nutrients however, are lost during blanching in boiling water bеcause they dissolve into the water. Steam blanching takes more time, but fewer water-soluble nutrients are lost. To minimize the loss of nutrients, blanch only the required length of time. But don't underblanch; the enzymes will not be inactivated, and the quality of the dried vegetables will be inferior. Testing for dryness Many factors affect the length of time needed for drying foods: temperature, air circulation, humidity, the kind of food being dried, the amount of food on a tray, the size of the pieces of food, and the total amount of food in the oven or dryer. Pieces on the edges of the trays will dry faster than pieces in the center. If slices are not all the same thickness, thin pieces will dry before the others. For these reasons you must test samples of the food from each batch you dry. You should test only a few pieces at a time. Be sure to let the pieces cool before testing. Warm food will feel soft and moist even when it is dry. Remove the pieces of food from the tray when they test dry. Return the rest of the food to the oven or dryer until drying is complete. When you think the food is dry, there are several ways you can test it to be sure. Test fruit by squeezing a handful. If the pieces of fruit spring apart and there is no moisture left on your hand when you open it, then drying is complete. To double check, cut through a piece of fruit; there should be no moisture on the inside. Dried fruit should be pliable and leathery. When you use an oven, drying takes as little as 6 hours to more than 10 hours. Most vegetables will be hard and brittle when completely dry. A dried piece will shatter when hit with a hammer. Exceptions are mushrooms, green peppers, and squash; they will be pliable and leathery. Vegetables usually dry in 4 to 12 hours. Herbs require 2 to 3 days' drying time when air dried and 2 to 3 hours if dried in the oven. You know herbs are dried when they are brittle and the leaves can be easily crushed. Dried jerky is dark brown to black. To test for dryness, bend a piece. It should bend like a green twig, not break apart completely like a dry stick. There should be no moisture inside. Conditioning It is very hard to dry all the pieces of food evenly. Depending on the size of the pieces and the location on the tray, some pieces will be too dry and others will be not quite dry enough. But you can condition food so that the whole batch will be uniformly dry. After the food is dried, cool it on the tray, then put the pieces of food in a large closed container such as a crock, a plastic jar, or a coffee can. Make sure the food is cool, because it will sweat if it is put into the container while still warm. Keep the container covered in a warm, dry, airy room. Stir the food once a day for a week to 10 days. Then package the pieces of food in smaller airtight containers and store. This conditioning allows the moisture from the underdried pieces to be absorbed by the overdried pieces. If drops of moisture appear on the sides or lid of the container, the food is not dry enough. Return it to the dryer and dry it some more. Pasteurizing Dried food is sometimes contaminated by insects or molds, which can cause spoilage. Sulfuring fruit usually prevents this type of contamination. After meat and vegetables have been dried, they can be pasteurized to make them safe. It is especially important to pasteurize food dried outdoors, where it was probably contaminated. To pasteurize, heat the oven to 175 degrees F. (80 C.). Set the pieces of dried food in a single layer on a tray or cookie sheet. Heat in the oven with the door closed for 15 minutes. Remove from the oven and allow the food to cool before packaging. Alternatively, the dried food can be pasteurized by freezing it for 1 to 2 weeks and then storing it. EXERCISES 1.

STORING Vocabulary of the text Vaporproof паронепроницаемый To deteriorate ухудшаться, портиться, разрушаться tight-fitting lid плотно облегающая крышка pint-sized container сосуд, вмещающий одну пинту After the food has been thoroughly dried, cooled, conditioned, and pasteurized, you can be sure of its quality and safety if you store it properly. Place dried food in moisture- and vaporproof containers with tight-fitting lids. Glass jars, coffee cans, and plastic freezer bags or cartons may be used. Containers that keep out light are best. If you use a coffee can, place sulfured fruit in a plastic bag first to prevent contact of the fruit with the metal. The sulfur can react with the metal and give an off-flavor to the fruit. It is best to package food in small quantities. Use pint-sized containers or small plastic bags. The bags should then be put into a large can or jar. If food is stored in large quantities, the unused portion may become contaminated each time you open the container. Be sure to pack the food tightly. Force out as much air as possible from the package before closing it. But take care not to crush the food. All dried food deteriorates over a period of time, but storing it in a cool, dry, dark place will help to preserve the color and flavor. Kitchen cupboards or a pantry are good places if they don't get too hot. A dry basement or a closet on the north side of the house is also suitable. You may store dried food in the refrigerator or freezer if you have the space. Once a package of dried food is opened, it should be resealed tightly and if possible stored in the refrigerator to prevent contamination and mold growth. Properly dried and stored, vegetables and jerky will keep about 6 months, fruits and herbs about a year. As a safety measure, examine stored food occasionally. If you find signs of a little moisture but no spoilage, pasteurize the food. If the food appears quite moist, repeat the drying process until thoroughly dry. Remember to cool the pieces before repackaging. If you see any mold growth on the food, throw away the entire batch. It's not safe! EXERCISES 1. Answer the questions: 1) How can a person be sure of quality and safety of food? 2) What types of containers do you know? 3) Why is it best to package food in small quantities? 4) What should be done to preserve the color and flavor of food? 5) Stored food should be examined occasionally, should’t it? 2. Give the summary of the text. Part II. FISH PROCESSING SOME IMPORTANT COMMERCIAL FISHES Fishes are cool-blooded, backboned animals adapted to live in water, breathing by means of gills and having limbs represented by fins or rudiments of fins. The skin is usually covered with scales, but these may be replaced by bony plates or rough tubercles and rarely the skin is entirely naked. The scales vary greatly in size and structure among the species. Whatever the nature of the diet of fish it is essential that it should contain the following ingredients: water, minerals, fats or carbohydrates, proteins and vitamins; water makes up about 75 per cent of the body weight of fish. Nearly all fishes are catholic in their choice of food, and many alter their habits as they age and with the seasons. For convenience fishes are classified according to their main methods of feeding in the adult age: 1) plancton feeders, 2) weed eaters, 3) mud feeders, 4) feeders on insects, crustaceas, worms and molluscs, 5) fish eaters, 6) parasites. All fishes have their definite spawning seasons. The majority of fishes spawn in spring or at the beginning of summer, but there are also fishes which spawn in other seasons. Approximately 12000 distinct species have been ascertained by scientists, yet about 15 per cent of these are regarded as fishes of commerce. And among the common commercial fishes the following species may be mentioned as the most important commercial fishes, on account of their abundance, high productiveness and high food qualities. The herring family. In productiveness none exceed those of the hering family numbering more than 150 species distributed over the greater part of the earth in both salt and fresh water, which contribute more to the support of the human race than any other family of fishes. The cod family (cod, haddock, hake and others) include about 140 species. They are distributed chiefly in the north temperate zone. These fishes are marketed largely in the fresh state and preserved by salting both dry salted and pickled. The family Salmonidae includes salmon, charr, trout (lake trout, brook trout, rainbow trout) and others. Some of them are anadromous. The most important members of the family are five species of salmon belonging to genus Onchorinchus, the more detailed description of which will be given below. The mackerels and mackerel- like fishes (including tunas) numbering 60 species are widely distributed. They are highly praixed for food in fresh, salted and canned state.

Characteristics of fish as raw material for industry Fish as food is one of our main sources of protein. But fish not only give a wide range of foodstuffs, they are also used as a source of valuable medicinal, feeding and technjcal products. That such full use can be made of fish is explained by the various histological structure and chemical composition of their different parts. The size, chemical composition and food value of fish depend on their species, age, sex, physiological state and on the conditions in which they live (the hydrology of water and the nourishment they are able to obtain from it). To be able to use fish properly and process them efficiently it is necessary to know their properties: their body structure, the size-to-weight ratio of their different parts and organs, their physical properties and chemical composition and the properties of proteins, fat, vitamins and other substances they contain. Since fish is highly perishable product, it is also important to know the nature and causes of the changes that take place in fish after death. In addition to the scientific, biological classification of fish into families and species, they are also divided, for practical purposes according to their size (whether large, medium or small); sex (male or female); season of catch; physiological state (whether hunting for food, laying down fat, in pick condition, filling or spent); according to fat content (fatty, medium or lean); according to manner of feeding (whether predatory on other fish, or feeding on plancton, benthos or vegetable matter); according to the region where they are found and caught (for example, Caspian bream, Aral bream, Azov bream) and according to the method of capture (trawled, netted or seined). All these classifications help to characterize the food value of fish, in some measure, and to show whether they can be preserved or are suitable for processig into various products. Notes on the text the size-to-weight ratio – соотношение размера и веса highly perishable product – скоропортящийся продукт laying down fat – жирующая (рыба) pick condition – нагульная (рыба) filling or spent – нерестующая или отнерестовавшая (рыба) according to fat content – по упитанности fatty – хорошо упитанная (рыба) medium – средней упитанности (рыба) predatory on other fish – хищная, поедающая других рыб vegetable matter – растительная пища trawled – траловая (рыба, выловленная тралом) netted – сетная (рыба, выловленная сетью) seined – неводная (рыба, выловленная неводом) Words to be memorized Histological, chemical, composition, hydrology, nourishment, properties, cause, classification, purpose, fatty, lean, benthos, vegetable, bream, capture, suitable EXERCISES 1) Give nouns or adjectives of which the following verbs are formed: characterize, realize, crystallize, metallize, theorize, organize 2) Answer the follwing questions: 1) What do the size and chemical composition of fish depend on? 2) Is it necessary to know the properties of fish to be able to use them properly? 3) Why is it important to know the nature and cause of changes that take place in fish after death? 4) What products may be obtained in processing fish? 5) What kinds of fishing gear do you know? 3) Translate the following sentences into Russian.

The chum salmon is of dirty silver colour. 3. Students have come to our ship to have their practice. 4. Some fish feed on plancton. 5. Herring is pelagic fish. The food value of fish The food value of fish depends first and foremost on whether it contains a large proportion of high grade proteins with all the (nonconvertible) amino acids essential for health. The other nutrients in fish – fat, vitamins and minerals are likewise important. When proteins are digested, they break up giving amino acids which eventually serve to build up the specific protein substances, enzymes and hormones peculiar to man. At the same time the amino acids taking part in metabolism, go through a series of changes which are accompanied by the evolution of eergy as vital heat. Hence proteins play the dual role of building and heat generating material. The end products of their breakdown in the body are urea, creatine, ammonia, carbon dioxide and water. The small amount of non-protein (extractive) nitrogenous substances in fish plays an important part in the digestive process, stimulating gastric juices and appetite. The role of fat is mainly to produce heat. Being transformed into carbon dioxide and water as a result of hydrolysis and oxidation, fat becomes the main source of the body heat essential for physical and mental work. The vitamins in fish are assimilated by man and serve to regulate metabolism. Vitamins A and D are particularly valuable. Minerals help to build up the bones, brain, nervous system, muscles and covering tissues of man. If man is deprived of an adequate supply of vitamins and minerals, his metabolism is upset, and serious illnesses result. The whole fish is not usually used for food, but only such edible parts as the body muscles (and sometimes milts, roes, liver and head muscle). To make a proper assessment of fish as food it is necessary to know its relative content of edible material as well as proportion and quality of the nitrogenous compounds, fat, vitamins and mineral salts. Not all fishes are edible. Some and some parts of others are unfit for food because they contain certain peculiar compounds with toxic properties. Poisonous material occurs comparatively rarely in the muscular tissue, but is more frequently present in the internal organs (gonads, liver, peritoneum) and in the head. The toxic matter is sometimes present at certain times (usually during the breeding period), and then disappears. Poisonous fishes live mainly in tropical waters and include the following: globefish, surgeon fishes, puffers, ilisha, some types of mullet, barracuda and other species. The poisonous fishes in the Russian waters are the Balkhash marinka, Issyk Kul osman (poisonous roe and peritoneum) and the barbel and khramula (poisonous roe).

Heinvented a process of heating foods sealed in glass cans, which caused them to keep indefinitely. Canning has advantages over some of the more ancient method of food preservation such as drying, salting, freezing and cold storage. Fish canning comprises the following steps: cleaning and trimming, salting, cooking or drying, packing into cans, exhausting, sterilizing or processing by heat and then sealing. Cleaning and trimming. In the canning of fish products cleaning and trimming generally consist of the removal of the head, viscera and tail fin, the washing of the viscerated fish to remove blood, and the trimming of the fish into pieces of proper size to pack into cans. Brining and pickling. In order to draw out the blood from the tissues, to give the flesh a proper degree of firmness and the desired flavour, it is practice to hold many kinds of fish before or after trimming in brine for a varied length of time. The time of holding and the strength of the brine depend largely upon the size and fatness of the fish, the nature of subsequent operation. Cooking. Many kinds of fish are subjected to some cooking or drying process before being packed in cans. This removes excess moisture and supplements the cooking of the fish in the can during the subsequent sterilizing process. The fish may be steamed and dried before packing or they are dried first and then cooked by a frying process. Filling {packing]. Filling may b accomplished mechanically or by hand. Mechanical filling is faster and gives a more accurate control of the net weight or volume of liquid. Exhausting. The objective of the exhausting is to remove air and gas from the can that the contents will be in a vacuum after processing and cooling. But the disadvantage of heat exhausting are as follows: non-uniformity and insufficiency of vacuum, protein denaturation and deterioration of flavour. That’s why exhausting is widely replaced by vacuum-sealing devices. These devicesensure more uniform vacuum, lessen the development of oxidizd flavours and lessen destruction of vitamins. Sealing (seaming). Seaming is the step in which the cans are passed through a sealing machine that rolls the curl of the cover and the flange or the can with the gasket or sealing compound into air-tight double seam. Sterilization. The canning of food products being based on the principle of sterilizingby heat, the final cooking or “process” is the most vital process and important step in the canning procedure. The term ‘process” as used in the canning industry, is synonymous with cook, anddesignates, in terms of temperature and time, the heat treatment given to the preliminary sealed container. The minimum requirement for the process of any product is that it be adequate to destroy the most heat-resistant organisms. In order to secure adequate sterilization within a reasonable time it is cusomary to sterilize cans in continuous rotary sterilizers where the cans are processed by steam under pressure. Testing. After the cans have ben cooled, it is customary to test them for leaks or defective seams before they are lacquered in an automatic machine, labelled and finally packed. EXERCISES №2.Answer the following questions: 1) By whom was the process of canning invented and when? 2) What is the main principle of canning? 3) What steps of canning do you know? 4) Can you name some advantages of canning? 5) What operations does cleaning consist of? 6) What is the purpose of brining? 7) What is the process of cooking necessary for? 8) In what way may filling be accomplished? 9) What are the main disadvantages of heat exhausting? 10) By what innovation is heat exhausting replaced? 11) What operations does a sealing machine perform? 12) What is the sterilization process necessary for? №3.

Translate the sentences into Russian: Процесс производства стерилизованных консервов был впервые разработан французским изобретателем Аппером в 1795 году. Затем новый метод стал применяться для изготовления рыбных консервов. Консервы изготовляются из рыбы высокого качества. Рыбу сортируют, моют, удаляют чешую, разделывают (удаляют голову, плавники, хвост, внутренности) и порционируют, если рыба большая. Затем куски рыбы солят в насыщенном солевом растворе. Продолжительность посола зависит от концентрации тузлука, размеров кусков, содержания жира в мясе. Введение соли в банки с заливкой позволяет обеспечить однородное содержание соли в готовых консервах. №6. Change the statements to questions supplying short answers: Enzyme activity is almost entirely halted by the heat treatment. The removal of water resulted in a shrinkage which permitted close packing. The cans are usually labeled by automatic machinery. The vacuum inhibits the aerobic bacteria from developing. The warm air moving about the fish removes the water and toughens the skin. Sterilization of the contents of the cans is necessary to ensure their keeping qualities. The cans are then placed in temporary storage for a few days, after which they are labeled. Quick freezing was first devised to improve the quality of frozen fish. №7. Change the following sentences according to the pattern: A. The increase in sodium concentration was a little greater in the partially frozen fish than it was in the fish stored at 30,5 C. The increase in sodium concentration was a little greater in the partially frozen fish than it was in those stored at 30,5 C. The period allowed fordrip to escape was greater than the period likely to occur in practice between cutting the fish and placing them into cans. The duration of the storage period is its duration from the time of the commencement of the experiment. The odours accompanying lipid oxidation under these conditions may be quite different form the odours associated with the oxidation or the three oils alone. The cooking method used in the determination or cooking losses is the cooking method or oven-baking. Further experiments were conducted in which the development of rancidity in trout stored at 25 C in open tanks was compared withthe development of rancidity in fish stored in sealed jars. B. Canning is a comparatively modern method of preserving fish and its origin dates from the discoveries of the French inventor N. Appert. Canning is a comparatively modern method of preserving fish, its origin dating from the discoveries of the French inventor N. Appert. The hot cans are then passed to the closing machine and the tops of the cans are rolled firmly. Smoked fish are produced by a combination of brining, drying and smoking and the two conventional types of smoke treatment are known as “cold-smoke” and “hot-smoke”. Hot smoking involves starting smoke treament of dressed fish or fish fillets at the temperature of 120 C and the temperature increases to 180 C. When the liquid is heated, then portion which is warmer becomes less dense and rises and the heat is distributed throughout the product. There are two methods of heat tranfer and convection is more rapid of them. C. The workers of the smoking department were given anincentive to because they had completed the production plan ahead of shedule. The workers of the smoking department were given an incentive to for their having completed the production plan ahead of shedule. The foreman is angry with them because they have not dressed the fish properly. They were reprimanded because they had roughly handled that lot of fish. The students were commended because they had designed a new fish filleting machine. Our foreman is not satisfied with us because we didn’t eviscerate the fish. He won the first prize as he had submitted a very interesting report. №8. Correct the following statements using the following phrases: I can’t agree with you I am afraid you are mistaken On the contrary To my mind In my opinion The hermetically sealed containers in which all commercially sterilized foods are packed are not proof against the entrance of microorganisms. Canning was discovered by Pasteur. Canning is the most ancient method of preserving fish. Most of the air is not eliminated form the cans before sealing. The hermetic sealing does not halt evaporation, humidity and most other chemical and physical causes of spoilage. The most serious effects of physical actions are : 1. corrosion of the can and solution of the tin in the food, 2. blackening of the interior of the can. The fish are represented by lobster, shrimp, crabs, cysters and clams of various species. The shell-fish are represented by salmon, sturgeon, herring, sardines and tuna. Glass containers are less difficult to sterilize and inexpensive. Paper lined cans are universally adopted for canning salmon and sturgeon. №9.Give the English equivalents of the following words and phrases: производство консервов, в меньшей степени, мясо ракообразных, моллюски, киты, водоросли, охлаждённая и мороженая рыба, сырец, разделять по видам (размерам), чистая проточная вода, освобождать от загрязнений, разделка рыбы, удаление чешуи, клей, укладывать в банку, насыщенный солевой раствор, слизь, бланширование паром, бланширование в кипящей воде, обжаривание в растительном масле, заливка, предварительная закатка, сортировка, покрытие лаком, этикетировка. №10.Render the text in English: В рыбной промышленности для производства консервов в основном используют рыбу и в меньшей степени мясо ракообразных, моллюсков, китов, а также водоросли. На изготовление любого вида консервов направляют безупречную по качеству рыбу. Кроме свежей и охлаждённой, используют мороженую рыбу. Процесс подготовки сырца состоит из таких операций, как сортировка, мойка, удаление чешуи, порционирование, окончательная мойка, посол рыбы. При работе с мороженой рыбой первая операция – размораживание (дефростация). При сортировке смешанные партии рыбы разделяются по видам и по размерам. При мойке вчистой проточной воде рыба освобождается от микроорганизмов и загрязнений (слизь, кровь, содержимое кишечника). Чешую удаляют до разделки рыбы. Снятую с рыбы чешую собирают и заготавливают в качестве сырья для получения клея. Технологическая цель разделки – отделить малоценные или несъедобные части тела рыбы. Порционируют рыбу в том случае, если тушки по своим размерам не могут быть уложены целиком в банку. Затем рыба подвергается тепловой обработке. Существует несколько способов тепловой обработки: Бланширование паром, в кипящей воде, солевом растворе или растительном масле при температуре 120-140 С. Обжаривание в растительном масле при температуре не ниже 160 С. Подсушивание при температуре 100С. Пропекание горячим воздухом при температуре 120-140 С. Заливка. После заливки банки предварительно закатывают, эксгаустируют, окончательно закатывают, стерилизуют. После стерилизации банки моют и охлаждают. Затем банки сортируют, покрывают лаком, этикетируют и упаковывают в тару. №11.Compose a dialogue using the expressions given below: Fish processing industry, to be organized, to be steadily expanding, nutritious, health-giving, canned goods, to improve appetite, to stimulate metabolism, to be explained by, high content of, proteins, carbohydrates, mineral salts, vitamins, to be used for, different culinary products, the former, the latter, to be canned in oil, to be canned in tomato sauce, to be particularly delicious. №12.

Fish oils are liquid fats andconsist chiefly of various proportions of glycerides and saturated and unsaturated fatty acids. Fish oils are obtained from oil parts of fish , whereas the fish liver oils are prepared from the livers only. Increasing interest in fresh liver oils as concentrated sources of vitamins A and D has led to a rather general use of many types of fish livers for this purpose. Although many liver oils have been examined from time to time the only one that is of commercial importance is that of the cod, of which enormous quantities are produced. The great importance of cod liver oil lies in its value as a curative agent in those diseases which are caused either directly or indirectly by malnutrition. Since the nutritive and therapeutic properties of cod liver oil is due to its content of the vitamins A and D, it is necessary to use special precautions not to destroy these components during the preparation, refining and storage of the oil. Seal oil is obtained from the blubber of various species of seal. Whale oil is extracted from the blubber of various species of whale. The first operation consists in stripping the blubbers from the dead whale; huge pieces are put through the chopping machine, taken up by an elevator and dropped into the cooker. Steam is turned on and after a sufficient period, generally six to eight hours, the oil runs off through a system of separating tanks to get rid of the free water, then into the store tanks. Fish meal is highly concentrated, nutritious feed supplement consisting principally of high-quality proteins, minerals and B-complex vitamins. It is obtained through the fish reduction process which consists essentially of grinding, cooking, pressing and druing of fish scrap obtained from filleting or canning operation or by processing whole fish as herring, capelin and pilchards. The moisture content of the resultant scrap must be 50-60 %. In the continuous drying drum the moisture content is reduced to 8-10 %. From the drying drum the material is fed to the hacking device then for sieving, and to the magnetic trapping device. Fish meal possesses exceptionally good nutritional values. It furnishes, in concentrated form, high quality proteins which contain all of the essential amino acids and it isparticularly high in lysine. It furnishes some of the B-complex vitamins, namely, riboflavin, niacin. pentothetic acid, choline and B12. Fish meal is high in mineral content ranging about 12% for a high protein meal to about 33% for a low protein meal. It is particularly high in bone and tooth building materials (calcium and phosphorus). It also contains most of the minerals that are necessary for building up and maintaining the animal body, namely, copper, and some trace elements. Practically all of the glue manufactured today are made from the waste products of fish especially from the sounds (bladders) and scale. The glue stock must be freed from salt or freshened before being made into glue. And then after special treatment with alkali and saline acid is cooked at 70-80 degrees C. Isinglass is an excellent raw material for producing fish gelain. The word “isinglass” is derived from a similarly sounding word in Dutch and German meaning surgeon air bladder or swimming bladder.

Chilled fish Vocabulary of the text Freezing point – точка замерзания To prolong – продлевать, отсрочить, продолжать, протягивать дальше To expose – подвергать действию ( солнца, ветра и т.д.) Merely – только, просто, единственно Raw fish – сырая рыба Cellular - клеточный Fluid - жидкость Complex – сложный, комплексный, трудный To grade - сортировать To conform – сообразовать(ся), согласоваться (to-с), соответствовать (to или with – чему-либо), приспособлять(ся) Fillet - филе Consumer - потребитель To entail – влечь за собой, вызывать что-либо Viscosity- вязкость, липкость, клейкость, тягучесть Moisture – влажность, сырость, влага Desication – высушивание, сушка, десикация To subject – подвергать воздействию, влиянию Dehydration - обезвоживание Subcutaneous - подкожный To impede – препятствовать, мешать, задерживать, затруднять Hygroscopic - гигроскопический Heterogeneous – гетерогенный, разнородный Appearance – появление, внешний вид Immersion – погружение, осадка Brine-spraying – обрызгивание рассолом The chilling of fish is a process by which the temperature of fish is reduced close to (but not below) freezing point. It delays the biochemical and bacteriological processes in fish and consequently prolongs the storage life of fish products. Fresh fish or fish products that have been exposed to cold until they are near freezing point are called chilled. The biochemical and bacteriological processes in them are merely delayed and not stopped; their storage life is therefore prolonged and will last so long as spoilage has not become sufficiently far advanced to impair their value as food. The storage life of a chilled product depends mainly on the quality of the raw fish, on the method and duration of chilling, and the conditions of storage. The freezing point for fish is between -0.6 degrees and -2 degrees, depending on the species and on the concentration of intercellular fluid. It is usually taken as -1 degrees. During chilling the heat transfer between the food product and the coolant is often accompanied by weight transfer (e.g. through evaporation from the surface with air chilling); chilling must therefore be regarded as a complex process of heat and mass transfer. The important considerations in preparing good quality chilled fish products are the biochemical and physical changes in the fish during chilling time, the temperature conditions, the chilling time and the equipment and technology used. Before chilling the fish are graded for species and size, their quality must conform to the technical requirements and is determined both by organoleptic signs and by physical and chemical information derived from laboratory analysis of specimens or by other means. Fish to be processed into frozen fillets or to be delivered in ice to the consumer may be live or dead, but must be absolutely fresh. During chilling important physical and biochemical changes take place in the product. The physical changes generally entail an increase in the density of tissues and in the viscosity of tissue juices and blood, and a loss in the weight due to partial evaporation of moisture from the surface dessication during air chilling. The extent of dessication depends on the properties of the product and coolant and on the conditions of chilling. The main properties of the product on which dessication depends are its specific gravity, the size of the individual fish, and the type of packaging during chilling and storage. The more water there is in the product, the more moisture will evaporate from the fish; lean fish consequently is more subject to dehydration than fatty, which contains relatively less water. The subcutaneous layer of fat offers protection against evaporation from the tissues. Products with a higher specific gravity contain more organic matter and therefore relatively less water. The evaporation surface depends on the size of the individual fish. Depending on its properties the packaging may offer complete protection against evaporation, or may impede and delay the process; but if it is hygroscopic, it will absorb moisture from the fish. The chilling time of fish and other marine products depends on their properties, the properties of the coolant, and the conditions under which the process takes place (cross-section of the product, thermal efficiency, specific gravity, temperature of the coolant, type of motion and velocity of the coolant, humidity, heat transfer coefficient from product to coolant). The methods employed for chilling fish and other fishery products are very varied, but may be divided into two groups according to the type of coolant: a) methods of chilling in a homogeneous coolant (as when fish are chilled in cold air or in a cold liquid, for example), and b) methods of chilling in heterogeneous coolant (for instance in ice). Fish are very seldom air-cooled at a temperature of -2 degrees to -3 degrees, because they chill slowly in air and deteriorate in appearance both while being chilled and during subsequent storage. The most used commercial methods of chilling are by immersion in a cold liquid, by spraying with cold brine, or by packing in crushed ice. Og these three methods tle least used is brine-spraying, and the most used is chilling in crushed ice. The method of chilling in liquid is to immerse the raw fish in the cold liquid (fresh water, brine or sea water). Fresh water which freezes at 0 degrees can only be used if the fish are to be lightly chilled. To chill fish thoroughly down to 0 degrees or -1 degrees, it is necessary to use either brine (for example a 2 per cent solution of sodium chloride) or sea water, both of which have a freezing point below 0 degrees, and can be kept at a temperature within -3 degrees and -4 degrees throughout the chilling process. It goes without saying that, since the fish are in direct contact with the liquid during chilling, the solution must be perfectly harmless to man. Notes on the text That have been exposed to cold until they are near freezing point- которые охлаждены почти до точки замерзания storage life – продолжительность хранения to impair their value- ухудшить их пищевые качества intercellular fluid – внутриклеточный сок heat transfer- теплообмен weight transfer - массообмен by spraying with cold brine – орошением холодным рассолом EXERCISES 1)Answer the following questions: 1) What is the chilling of fish? 2) What is the freezing point of fish? 3) How can you characterize changes occurring during chilling? 4) What does the chilling time of fish depend on? 5) Do you know the methods employed for chilling fish? 6) What measures should be taken to retain the freshness of fish after they have been captured? 7) What is to be done if we want to hold fish in good edible conditions for a long time? 8) Have you ever seen the process of refrigeration?

PRODUCTION OF FROZEN FISH Vocabulary of the text The eutetic point of food products –эвтетическая температура пищевых продуктов Powerconsumption – расход энергии Tubular rack – трубчатый стеллаж Ice-and-salt freezing – льдо-солевое замораживание Layer by layer - послойно Latent heat – теплота испарения Assembly – агрегат Perishable food products may be kept much longer by freezing, provided that two conditions are observed: a) the product must be frozen to as low a temperature as possible; and b) most of the fluid in the product must be converted into ice. The second factor is particularly significant for fish, since the fluid in it constitutes a solvent for many organic and mineral substances and flavours the growth of microorganisms and the development of biochemical reactions. Freezing is a process by which the temperature of the raw fish is reduced from the initial level to between -16 degrees and -18 degrees, and most of the fluid in it is converted to ice. The euteric point of food products, that is the minimum temperature at which all the fluid in it is turned to ice, is -55 degrees to -65 degrees C, but such a low remperature cannot generally be reached in the food industry. Heat transfer during freezing is accompanied by mass transfer. Consequently, freezing must be regarded as a complex process of both heat and mass transfer. The biochemical and physical changes in the fish during freezing, the refrigeration conditions (speed, duration, final temperature of the frozen fish), power consumption, and the peculiarities of the refrigeration method used – all are very significant factors in preparing high quality frozen fish. Only live and perfectly fresh fish should be taken for freezing. It is also essential that they be graded by species and size. The freezing of fish is accompanied by important biological and chemical changes. The biological changes include the inhibition of microorganisms at the surface and in the interior of the fish, and even a reduction in the number of bacteria at the surface immediately after freezing. Owing to the low temperatures and the changes that result in the state of aggregation in the product, freezing is more lethal to microorganisms than chilling, and frozen fish therefore will keep for a long time. Biochemical reactions take place more slowly at low temperatures, but are not arrested even when the product is frozen. Glycogen breaks down during freezing, and lactic acid forms. The maximum accumulation of lactic acid occurs in the temperature range between -2.5 degrees C and – 3.7 degrees C known as the critical range. With slow freezing, that is, at a comparatively high temperature, glycogen breaks down quickly. During refrigeration substantial protein changes occur – the protein becomes denatured, as a result of which solubility changes drastically ang the capacity of the product to swell and retain tissue juices is reduced. All this detracts from the food quality of fish, the flesh becomes dry and hard and loses certain properties essential for further processing particularly for canning. Methods of fish refrigeration. The methods and equipment for commercial freezing are very varied. Freezing in a cold air medium, for example, may be carried out in natural conditions, or in a freezing chamber where low air temperature is maintained by artificial means, or in a special freezer in which cold air is circulated fairly rapidly. If a cold liquid medium (brine) is used as coolant, the fish may either be placed in direct contact with the brine, or may be separated from it by heat-conducting surface. Both ice and brine may sometimes be used for either contact, or indirect freezing. Lastly, new methods of freezing with a boiling coolant are being developed. Freezing by natural frost is used in very cold climates, where fish are caught under ice and immediately laid out alive on the ice in a single layer, so as to expose as much of their surface as possible to heat transfer with the atmosphere and ice. Blast freezing. In old-style freezers fish are frozen on tubular racks in a refrigerating chamber. In these conditions in which part of the fish is in contact with metal, and part with slowly circulating air, freezing is slow and uneven. In modern freezers the rack method has been replaced by a blast of cold air. Various apparatus and installations have been developed not only ensuring high heat transfer coefficient, but also providing mechanical means for loading and unloading the fish. Ice-and-salt freezing uses the principle of spontaneous cooling of a mixture of ice and salt (NaCl). The process taking place simultaneously in the mixture are ice melting and saltmelting, both of which absorb heat. For a complete interaction between the constituents of the mixture the contact surface between them should be as large as possible. The technology of this method of freezing is simple: fish are placed in the mixture layer by layer and are either kept in direct contact with it (contact freezing) or are separated from it by a heat conducting wall (indirect contact freezing). Freezing in a boiling refrigerant. The principle of freezing products by immersion in a non-toxic evaporating refrigerant is probably better and more efficient than any other. It offers the most favourable heat transfer conditions: fullest use, is made of the latent heat" of evaporation of the refrigerant, and the product, which is in direct contact with it, is quickly frozen. The ix frigerant is admitted directly to the freezer through control valve and is evaporated in it at a very low temperature through the heat transfer from the product. The functions of the evaporator and of the freezer are here combined in the same assembly."

SALTING Vocabulary of the text To the daintiest spiced delicatessen – до самых нежных деликатесов Marinaded items – маринованные продукты Allowed to become permeated by it – способствуют проникновению соли (в рыбу) Is forced out of the tissues – вытесняется из тканей (влага) The salt has struck – соль пропитала рыбу Preservative action manifests itself – консервирующее свойство обуславливается This time is conditioned by two factors – это время зависит от двух факторов Through being very coarse – из-за того, что была применена слишком крупная соль Which are levelled out with a rake – которые выравниваются граблями With split fish – при посоле распластованной рыбы Salting is both a method of preserving fish and a preliminary operation to smoking, drying, and marinading. Many types of salted fish in which a pleasant flavour and aroma are produced by salting, make tasty snacks and appetizers — herrings, sprats, anchovies, salmon, whitefish, etc. The products made from them are varied — from salted fish proper to the daintiest spiced delicatessen and marinaded items — and the range and quality are being constantly extended and improved. In a narrow sense, salting is a combination of operations by which fish is placed in contact with salt (whether as crystals or in solution) and allowed to become permeated by it. These operations include mixing the fish with salt, laying and keeping the fish in the container in which it is salted, restocking, etc. Salting may also be taken to mean the combination of physico-chemical processes by which salt penetrates the fish, and moisture is forced out of the tissues, producing a change in weight. When this is implied, it is better to say that (he salt has "struck". Salt solutions are known as brine. Brine that has formed as a result of salt reacting on the fish (i.e. the aqueous salt solution released by the fish) is called natural brine, and brine prepared by dissolving salt in water — artificial. The feature of the natural brine is that it contains certain proportion of dissolved or suspended organic matter. The amount of salt used is sometimes more than can be dissolved in the water contained in the fish. Some undissolved salt (known as excess salt) then remains in the vat after the fish arc removed, and there is also a sediment of skin, coagulated proteins, fragments of fins, etc. Preservative action of salt. When common salt is introduced into fish in sufficient quantity it arrests autolysis and spoilage. The common salt not only causes plasmo-lysis in the bacterial cell but also blocks the protein nuclei which are effected by enzimes. Its preservative action manifests ifself by altering the state of the proteins and enzymes in such a way that proteins become impervious to the action of enzymes, and the latter lose their efficacy. Common salt has a bacteriostatic and bactericidal action, that is, it both delays the growth of bacteria and kills them. The growth of many putrefactive rod bacteria in artificial media is arrested by a 10 per cent salt concentration that of putrefactive cocci by a 15 per cent concentration. But a higher concentration than this is required if fish is to be protected from spoilage. Salted fish with a concentration not exceeding 15 per cent can be kept in the cold room at a temperature of 0°C or lower. Only heavily salted fish with a concentration close to a saturation will tolerate prolonged storage at a temperature of 10°C. The salting process. Successful preservation depends a great deal on the time taken for the salt concentration inside the fish to reach the minimum level to arrest autolysis and the growth of micro flora. This time is conditioned by two factors:(a) the rate at which salt is dissolved, forming brine, and (b) the rate at which it penetrates the fish, and water is extracted. Provided that the fish and salt are thoroughly mixed, and the salt is of the right quality, the latter dissolves more quickly than the fish become salted. Salting is therefore delayed if the salt dissolves too slowly through being very coarse. Successive salting consequently depends basically on the speed of penetration of the salt, i.e. on the time taken for its concentration to increase in the fish fluid. With equal permeability of tissues the amount of salt penetrating fish in unit time will depend on the surface area of the fish and on the area to thickness ratio, that is on the specific area of the fish. Brining may be carried out in several ways which fall basically in two groups: a) in which the fish are salted in the same brine from start to finish, and b) in which the brine is replaced by a fresh, stronger solution after it has weakened. There is also the method of mixed salting which is carried out as follows: a small amount of strong brine is poured into the bottom of the tank (barrel or vat) and fish put into it until a fairly thick mixture forms, and the fish are entirely covered by brine. They are then spread with salt, and more fish are fed in the shallow layers interspersed with layers of salt which are levelled out with a rake. If herring are salted in barrels, they are first mixed with salt. Larger fish are placed in raws dry, and brine is admitted to the tank from a reservoir placed in one corner. With split fish the gills and belly cavity of each fish are stuffed with salt.

MARINADING OF FISH All marinades may be divided into two groups: (a) cold or salt, and (b) warm marinades prepared from pre-fried, pre-cooked, or pre-smoked fish. Cold marinades are extensively used, because they keep well and are easier to prepare. Warm marinades are in fact made-up cooked dishes, and they will not be discussed here. The preservative action of vinegar and vinegar-salt solution. The development of putrefactive micro-organisms is greatly delayed in an acid medium with a vinegar concentration of 1 to 2 per cent. With a higher proportion of acid, a number of bacteria die. The various micro-organisms react differently to being kept in an acid medium; some, like yeasts and mould, for example, will even thrive. Mould develops readily in an acid medium, and we know from experience that marinades are frequently affected by them. Moulds gradually decompose the acetic acid and thereby create favourable conditions for development of putrefactive bacteria. Marinades are prepared from edible acetic acid (essence or vinegar) at a strength of 80 per cent. The acid is obtained either by dry distillation of wood or synthetically from acetylene. Its basic requirements are that it must be colourless and transparent, with no resinous odour, and contain no mineral acids or salts of heavy metals. Acetic acid is completely miscible with water Sometimes wine vinegar obtained by fermenting wine or diluted alcohol is used for marinades. Wine vinegar has a beеter taste and flavour, but as it contains only 3 to 5 percent of acetic acid, it cannot be used unless it is produced on spot. Marinading technique. Cold marinades may be prepared from both fresh and salted fish. It is usually considered that fresh fish gives a pleasanter taste, but the better opportunities offered today for processing light salted intermediate products have led to the bulk of marinades being prepared from lightly cured fish. Fish used for marinading include herrings, whitefish, and sardines, i.e. mainly those types that mature through salting. Marinades may be prepared from whole fish3 or from dressed ones.4 The dressing of the fish gives a good quality product and is also economically profitable. Gutted fish5 keep better, and some methods of dressing give the fish an attractive appearance. Defects due to mechanical damage are eliminated through dressing. Fish for marinading are gutted, gibbed, or cut up into trunks, pieces, or fillets. Processing fresh fish. If fish are marinaded fresh, they are dressed and washed, and then placed in a vat with a vinegar and salt solution. As a result, they are preserved and acquire a salty-sour taste. The salt and acid are chosen according to the season and to the type of flavour required. The marinades preferred in the Soviet Union are more salty than sour; the salt concentration in the vat therefore varies from 12 per cent to 18 per cent. In Western Europe, on the other hand, solutions contain 6 per cent to 12 per cent salt and up to 6 per cent vinegar. Packing fish in containers. The usual container for cold marinading fish is a wooden cask or a keg. Since marinades are fairly perishable, casks should be scrupulously clean. Wooden barrels can be a source of mould infection for fish, so they must be made of good quality wood and be thoroughly washed before use. The best method of treating them is with live steam. Small-sized fish, or fish cut up into small pieces, are poured into the barrel and merely spread out in it. The fish may be fixed with condiments either on tables or during filling of the barrel. Large-sized fish (herrings) are packed in rows, and each row sprinkled with the condiment mixture.

Even a slightly acid salt solution makes fish flesh firmer and reduces swelling. 6. In warm weather the vat holding the solution of salt should be kept cold. 7. The readiness of the fish for further processing is determined by chemical analysis. DRYING Drying after salting is one of the oldest ways of preserving fish. It is simple, does not require complicated equipment, and gives a product a long storage life. Both mechanical and natural drying are utilized. Dried products include dehydrated fish which needs to be soaked and cooked before use. Fish that is dried naturally becomes desiccated and undergoes complicated biochemical protein changes as a result of which it loses its raw flavour, loses moisture from the flesh, and becomes permeated with fat. It can then he eaten as it is, without cooking. Naturally-dried salted Caspian roach has a wide market in Russia; and naturally-dried salted sturgeon and salmon fillets ("balyk") are unsurpassed for flavour. The curing of smelt and other small fish by hot drying is a widespread and commercially important method of processing. In recent years vacuum drying has been used more and more, and this form of dehydration has become a method of preservation and treatment of great economic importance. Drying under natural conditions. Fish dried under natural conditions at a temperature not exceeding 35°C, give a tasty and valuable product. The fish are usually hung on rack in the open air in warm and dry weather, or are dried in special chambers with artificially ventilated warm air. Thermal conditions of this kind do not expose the flesh to heat denaturation, and the proteins suffer little change. The enzymes in the cells and tissues do not break down and so are able to catalyse changes in the proteins and fat, and conditions are right for the fish to mature. The drying process consists, in effect, of a gradual loss of weight moisture evaporation. At the same time, complex biochemical processes take place that considerably alter the taste and external appearance of the fish, and make it readily consumable as it is, in uncooked form. Drying Caspian roach. Caspian roach are usually dried in the spring (middle of March to middle of May), hung on racks in the open air. During this period the weather in the area is dry, cool, and sunny, with easterly winds — all fa vouring drying. The roach are either delivered to the drying sheds alive in well-boats or in fresh, chilled, or lightly salted for). Live fish are kept from six to twelve hours afloat on special grids to let all the slime accumulate on their surface; with fresh fish the slime is easily washed off. To insure uniform salting and drying the roach are first graded for size, only fish of one size being fed into the salting vat if fish are salted before drying. Natural 20 per cent brine is poured into the bottom of the vat to a depth of 20 centimetres before the fish are added. Each row of fish is sprinkled with salt. Salt requirements are 12 to 14 per cent of the weight of fish, plus 1 per cent for sprinkling. The top layer of fish is covered with a layer from 1.0 to 1.5 centimetres thick. Salting time depends on the size and temperature of the fish. After being removed from the vat the salted roach are threaded on strings (four to six fish to a string with large specimens, eight to ten with medium-sized ones, and fifteen with small ones) and washed in three tanks (being scrubbed with a fibre brush in the first tank, and rinsed in the other two). The washed fish are hung on racks, with their backs to the bars and their bellies exposed (eight strings of fish per metre of bar on average). The fish are removed from the racks as they are ready, i.e. when they have lost sufficient moisture and their flesh has acquired the peculiar flavour of matured fish. There should be no taste of raw fish. The gonads should be pinkyyellow and firm, and the flesh should be firm and elastic. Pacific salmon cured fillets are processed only from the highest quality fresh fish — large chum salmon, chinook salmon, and large or medium-sized red (sokeye) salmon. The fish are dressed by cutting the belly away from the back. The cut is made from the shoulder bone, 1.5 cm. below and parallel to the lateral line as far as the anal fin; the belly together with the anal fin are severed by a turn of the knife. The head and dorsal fin are then cut off and the viscera removed. The back is freed from the kidneys and blood by means of special scraper. The fish is then washed, and slime and other impurities1 scrubbed away with a brush. After gutting and washing, the pieces are graded according to the size, and then they are salted in cold premises, the backs being rubbed with salt from tail to head and put in the vats with the cut sides uppermost. At a fish temperature between 7°C and 15°C each row of fillets is sprinkled first with 18 per cent of salt, then with 15 per cent of ice, then again with 6 per cent of salt. Total requirements in relation to fish weight are 24 per cent salt and 15 per cent ice. After five or six days, when the fish have a salt content of 8 per cent, they are immersed for four or six hours in a tank with fresh water in order to prevent a salt crust forming on the product during open-air drying. After soaking and washing in clean water the fish are hung on racks in an open shed, protected from the sun and rain. In dry weather they take about a month to dry. The finished, dried product has a salt content of 6 to 14 per cent and 45 to 55 per cent of moisture.

FISH SMOKING Smoked fish is a nourishing and delicious product ready for consumption as it is, that is to say uncooked, and naturally, therefore has a large demand. Two methods of smoking are to be distinguished: cold and hot. The flesh of hot-smoked fish is delicate, succulent, and tasty, but the product does not travel or store well; consequently it is mainly processed at fish factories in large cities where a good market is assured. Cold-smoked fish is more stable and is noted for its pleasant odour. Hot smoking. Fish may be hot-smoked either in batch kilns or in continuous ones. The former are of two types: chamber kilns in which the fish are loaded and unloaded at one end, and tunnel kilns in which the fish are loaded and unloaded at opposite ends. Chamber kilns (small).The smaller types of chamber kiln are cabinets with an area of 1.8 ni.Xl.3 m., and height of 2.2 m. Fish are loaded on racks in four to six tiers. Chamber kilns (large). The traditional kiln has an area of 2.5 m.X4 m. and a height of 2.3 m. The fish are charged rnanualh/ on poles; and the fires are lit on the floor of the kiln. In a kiln of recent design the fish are put into the smokehouse in cages along a monorail. The fuel is burnt on trolleys which move through the smokehouse on rails. As the rails are laid in two tiers it is possible to heat the fish even-I all round. The smokehouse has an exhaust pipe with a damper to regulate the draught, the damper being controlled by a lever outside the door of the smokehouse. The hearths are accommodated in a cellar beneath the smokehouse. The ground floor consists of a chamber holding three fish cages, each 1.7 ra.Xl m.Xl-6 ni. Steam radiators7 are fitted along the walls of the kiln. Productivity is increased by the use of the steam and artificial ventilation. The smoking process. Fish selected for hot smoking must be first- or top-grade, chilled or frozen while still fresh. The sequence of operations is as follows: defrosting+washing + dressing + washing + salting -|- rinsing -|- binding + drying + cooking + smoking + cooling + grading +packing. Cold smoking. Fish intended for cold-smoking are first salted, after preliminary grading for size and quality, which makes it possible to market a uniform product with a definite moisture and salt content. Smoking chambers for cold-srnoking are of several kinds. The Astrakhan type is made of wood, with an area of 30 to 60 square metres and height of 2.5 to 3.0 metres, is lined with bricks to a height of 0. 8 metre, and has a beaten clay floor. Each chamber has a door, two to four ventilation windows 25x40 cm. near the top, and four exhaust pipes. Fish are hung in one, two, or three tiers. Four to twenty chambers may be fitted in the same sheds in a single or double row. Smoking. During smoking fish dry and absorb the aromatic substances of the smoke. Once the relative humidity of the smoke is above 75 to 80 per cent drying is drastically slowed. The higher the temperature of the smoke, the more moisture it can absorb, and the more water it is capable to extract from the fish. To keep relative humidity in the smoke from rising too high the smoking chamber should be fitted with flues ensuring a good draught, and should be ventilated quickly and at the right moment. When fish are charged in the chamber, attention is paid to ensuring that they do not touch. The fish are usually charged in three to eight tiers 25 to 30 centimetres apart. The tails of the fish in the bottom tier should be 1.5 metres above the floor of the chamber. At fish factories of the Caspian basin the only fuel burned for smoking is sawdust, which is strewn on the floor of the chamber in oblong or round heaps — one for each 2.5 square metres of the chamber area. An improved and accelerated method of smoking fish has been proposed by the staff of the Leningrad Fish-packing Plant. Wood is burned as a mixture of shavings and sawdust in a 2:1 ratio; every 1.5 — 2.0 hours a fresh measured quantity is added, and the combustion process is regulated continually. No fuel may be used for smoking if the substances generated during its combustion are likely to give fresh and unpleasant odour or taste. The only fuel suitable is wood (logs, shavings, or sawdust). Pine and fir give smoke, containing a great deal of tar, which imparts flavour to the smoked fish; if coniferous wood shavings,therefore, are used, they are first seasoned and their aromatic substances allowed to evaporate for several months. The best woods for smoking are alder, beech, oak, poplar, and birch (stripped of bark).

Read and translate the text: Roman Cuisine in the Imperial Age The Romans in the Imperial Age had two main daily meals, but they often added a breakfast of bread soaked in wine, grapes, olives, milk, and eggs. The midday meal was a light affair of cold dishes. Dinner was the main meal: a feast of hoer d'oeuvres (mixed seafood) followed by game, pork, veal, goat, fowl, fish, and sweets with a honey base, fresh and dried fruit. Meals were accompanied by sweets and aromatic wines. Cuisine in the Middle Ages The cuisine of the Barbarians who invaded Italy from the 5th century AD was considerably different from that of the Romans; it was based on roast meats, stuffed pastries, and oven-baked pies. For the Italian population reduced to poverty and servitude, food was rather poor and consisted of cereals, milk, cheese, and vegetables. Gradually, culinary art began a revival, especially after 1000 AD, in the agricultural centers around the monasteries where the famished and terrorized population had taken refuge. The general tendency was to make food healthier, more appetizing and digestible, eliminating elaborate preparation and introducing more fresh fruit and vegetables. 4. Answer the following questions: 1. Did the Romans in the Imperial Age add a breakfast of bread soaked in wine or a breakfast of bread and butter? 2. When was the general tendency to make food healthier? 3. Did culinary art begin a revival after 1000 AD? 4. Were meals accompanied by sweets or aromatic wines? 5. What was the main meal? 5.

Read the text and define the meaning of new words. Translate the text. Gastronomical Revival in the Feudal Courts Around 1200 AD, life in the courts became less difficult, commerce and social life resumed, and the feudal lords organized frequent celebrations, feasts, and tournaments. However, important meals had no variety or cohesion. Endless dishes of roast meats were seasoned with a sauce made of garlic, herbs, sweetmeats, and almonds. The dinner ended with cheese and fruit. There was little change from the Roman cuisine; however, spices made their appearance from the East in greater quantity. Their exotic aroma was used to scent the food - a prelude to future cuisine refinements. 2. Read the micro text and define the main idea of the text. Although there had been a spice trade during the Early Middle Ages, it really intensified after the Crusades with the direct contact of Europeans in the Arab world. Spices were very much in demand for cooking and medicine. They had other more practical and important qualities: the preservation of meat and fish, and the flavoring of otherwise bland foods.

The Culinary Discoveries of Great Explorers Among the many goods brought to Europe and Italy by the explorers there were some foods whose importance was understood only in later times. Maize was widespread in North Italy. At the time of the great famines of the 17th century, became the base for the most common dish. Other imported foods were potatoes, tomatoes, and beans. Rice, imported from Asia, was an instant success and joined the pasta as the nation's first course. Venetian merchants imported sugar from the Orient, which initially was used in medicine; only later it was added to cooking. Coffee, of Turkish origin, was also initially used as a medicine. 4.

Cuisine in the Renaissance The 15th and 16th centuries were a particularly fortunate time for Italian cuisine. A greater variety became available in the preparation of foods: soups, grilled, roasted, and boiled meats; meat pastries, fish, vegetables, olive oil, refined salads, almond-based sweets, pinenuts, and candied fruits; cane sugar began to replace honey. Renaissance court banquets were famous for their grandiose variety and refinement. The food of the common people remained rather simple: beans, lentils, chickpeas, buckwheat (used to prepare soups and porridges), eggs, cheese, and mutton. Culinary Art and Etiquette in the Renaissance Italian cuisine reigned supreme from the end of the Middle Ages to the 17th century and had a notable influence abroad. In particular, Catherine de' Medici popularized Italian recipes (especially sweets and ice cream) in France when she married King Henry II. It was also in this period that the first menus and table manners were established. Italians were the educators of Europe, and the famous 'Galateo' by Monsignor Della Casa was quickly translated and distributed throughout Europe. The principal innovation was the use of individual cutlery. Lesson 7 1. a) Cover the right column and read the English words.

Read and translate the text. Cuisine in the 17th, 18th, and 19th centuries In the 17th, 18th, and 19th centuries, the upper classes enjoyed a refined cuisine. Every official event became a pretext for sumptuous feasts. Meals were abundant, hors d'oeuvres and delicate French-style soups were followed by numerous meat and fish dishes, vegetable purees, intricate sweets and fruit - all presented with the utmost care, particularly in the restaurants. Still, the food of the common people remained frugal and monotonous, based on bread and vegetable soups, beans, cabbages, and potatoes. Cheese and eggs were very much used, as were polenta and pasta, which were made of flour and eggs. Foreign influence and the spread of new foods From the 17th to the 19th century many new dishes arrived from France: consommés‚ crepes, purees, jellies, gravies, and delicate, tasty sauces such as mayonnaise and béchamel. The presentation of food was very important, and its execution was of great refinement. Even English cooking became accepted with such typical dishes as roast beef, pudding and, above all, tea, although it was less popular than coffee and chocolate. In fact, coffee became as popular as to give rise to the coffeehouses, or cafés. 8. Pair work. Put the questions given below to your group-mate and ask him/her to answer them.

The involvements of industry in the food sector, and subsequent improvements in preparation, conservation, and distribution of foods, have increased the production of foods worldwide. However, Italian cooking has preserved its quality, and Italy is still a country of noble culinary tradition. Italian cooking is very difficult to pin down -- almost every city and town has its specialties, and there are regional trends too; the end result is a huge number of local cuisines rather than a single national cuisine. However, there are some dishes that you will find almost everywhere, and that are now standards among the many Italian communities scattered across the globe. Lesson 9 1.

Read and translate the text: Pizza and pizza-like creations are common throughout Italy, and a number of regions claim the honor of having invented it in the first place. Not that the invention could ever be proven -- the idea of slipping a flattened disk of dough graced with a topping into a hot oven and baking it quickly is amazingly simple, and many people must have come up with it independently. Indeed, in a post to It.Hobby.Cucina, the Italian general cooking newsgroup, RoDante da Fano traces its origins from Ancient Egypt to Imperial Rome, where there were a number of different kinds of flat baked breads with a variety of sweet or salty toppings, and goes on to say that the descendents of these proto-pizzas were common throughout the peninsula in the 1700s. In 1835, he continues, Alexandre Dumas noted in his diary that "in Naples pizzas are flavored with oil, lard, tallow, cheese, tomato, or anchovies…" Other chroniclers listed other common toppings, also noting that pizza was a cheap food that Neapolitans ate for breakfast or lunch; in the 1870s things stabilized to a degree, when a Neapolitan pizzaiolo created the Margherita, which he named after Italy's beautiful queen, by sprinkling a few fresh basil leaves over a pizza topped with mozzarella and tomato -- red, white and green, the national colors. The Margherita is still the most popular pizza today, perhaps because it's simple, light and tasty. It's also, in some ways, a better foil for the pizzaiolo's skill than some of the pizzas with more elaborate toppings, because what little there is has to be perfect: Well-risen wellturned dough; mozzarella di bufala, made from the milk of the water buffaloes that are raised around Naples; good light tomato sauce; good extra virgin olive oil; and fresh basil. Ideally it should be baked in a wood-fired oven, whose hot floor will rapidly crisp the dough. At home, a pizza stone can take the place of the terracotta floor of the wood-fired oven, and one can substitute the mozzarella di bufala with mozzarella fiordilatte made from cow's milk (as do most Italian pizzerias). The important thing is that you use good quality ingredients, and make your pizza with care. 7. Answer the following questions: 1. Must many people have come up with it independently? 2.

Read and translate the text. At home, a pizza stone can take the place of the terracotta floor of the wood-fired oven. The important thing is that you use good quality ingredients, and make your pizza with care. To begin, the dough, for 2 12-inch crusts, you'll need: 1 package (2 1/4 teaspoons) active dry yeast 1 1/3 cups warm (105-115 F, or 42-45 C) water 3 1/2 -3 3/4 cups all purpose flour 2 tablespoons olive oil A healthy pinch of salt Begin by dissolving the yeast in the water, in a large mixing bowl; let it stand for 5 minutes. Add the remaining ingredients and mix, either by hand or with a mixer set to low speed, until the ingredients are blended. Now hand-knead the dough or mix it with a dough hook setting the speed to low for about 10 minutes, or until the dough is smooth and elastic. Coat the insides of another bowl with olive oil and turn the dough in it to coat it too, then cover with plastic wrap and set it in a warm place to rise for an hour, or until it doubles in volume. For the baking, if you have a wood-fired pizza oven, fire it up. If you are instead using your kitchen oven, preheat it to 475 F (250 C) -- if you are using a baking stone it should heat for at least 45 minutes. Otherwise grease and dust two flat baking tins with corn meal. Divide the dough in half, shape each half into a ball and let them sit for 15 minutes. Then shape them into disks, stretching them out from the center on a floured surface. Do not roll them, because rolling toughens the dough. Ladle and spread a half cup or so of tomato sauce or chopped canned tomatoes over them, leaving an inch of sauce-free rim, add the toppings (see next page), and bake. If you're using a baking stone and have a baker's peel (a thin metal disk with a handle), lightly flour it, slide the pizza onto it, and transfer it to the stone with a deft yank -- the flour will keep the dough from sticking. If you don't have a peel, use a flat cookie sheet instead, lightly flouring it, to transfer the pizza from the work surface to the stone. If you're using a metal baking pan you should bake the pizza towards the bottom of the oven. In a recent post to Rec.Foods.Cooking Karen suggested baking on the bottom rack for about 4 minutes or until the pizza is firm enough to slide off the pan, and then slide it from the pan straight onto the rack to finish cooking. The pizza will in any case be done when the crust is browned and the toppings are cooked; this takes 3 minutes in a wood-fired oven and about 15 at home. If you discover that the mozzarella begins to brown before the other ingredients are cooked to your satisfaction, the next time, add it after the pizza (with the other toppings) has baked for abоut 5 minutes. Having said all this, once you have your dough, what to do with it? The standard topping combinations one encounters in Italy differ somewhat from those I have encountered elsewhere. The quantities given on the next page will be sufficient for one pizza each, so if you make the dough given above you will need to double the amounts, or select two. 8.Pair work.

Pizza Margherita: To honor the Queen You'll want 1/2 cup tomato sauce or chopped canned tomatoes, about a quarter pound of shredded mozzarella, and 3-4 fresh basil leaves. Spread the tomato sauce on the dough, sprinkle with the mozzarella, drizzle with a few drops olive oil, add the basil and bake. Pizza Marinara: The garlic-lover's delight You'll want two cloves (or more or less to taste) finely sliced garlic, and 1/2 cup tomato sauce or chopped canned tomatoes. Spread the sauce over the pizza, sprinkle the garlic, drizzle with a few drops olive oil and bake. Pizza al Prosciutto: A standby You'll want 2-3 ounces finely sliced cooked ham, shredded, 1/2 cup tomato sauce or chopped canned tomatoes, and 1/4 pound shredded mozzarella. Spread the tomato sauce, sprinkle with the mozzarella and ham, drizzle with a few drops olive oil and bake. Pizza Prosciutto e Funghi: Another standby you’ll want about a cup finely sliced Champignon mushrooms, 1/2 cup tomato sauce or chopped canned tomatoes, 2-3 ounces finely sliced ham, and 1/4 pound shredded mozzarella. Spread the tomato sauce, sprinkle the other toppings over it, drizzle with a few drops olive oil and bake. La Napoletana: Yet another standby 1/2 cup tomato sauce or chopped canned tomatoes, 1/4 pound shredded mozzarella, 3-4 anchovy filets or more to taste, 1 tablespoon or so rinsed salted or pickled capers, a dusting of oregano. Spread the tomato sauce over the pizza, dot it with the remaining ingredients, drizzle with a few drops olive oil and bake. L'Atomica: A fiery wonder though the one constant is a healthy jolt of crumbled red pepper; the other ingredients vary considerably from pizzaiolo to pizzaiolo. Variation 1: 1/2 cup tomato sauce or chopped canned tomatoes, a tablespoon or to taste salted or pickled capers (rinsed), 3-4 anchovy fillets, boned, a dusting of oregano, and crumbled red pepper, to taste. 1/4 pound shredded mozzarella is optional. Assemble the pizza, drizzle with a few drops olive oil and bake. Variation 2: 1/2 cup tomato sauce or chopped canned tomatoes, 3/4 cup finely sliced mushrooms, a dusting of oregano, crumbled red pepper to taste, and 1/4 pound shredded mozzarella (optional). Assemble the pizza, drizzle with a few drops olive oil and bake. Pizza Quattro Stagioni: The four seasons 1/2 cup tomato sauce or chopped canned tomatoes, 3-4 canned artichoke hearts, quartered, 5-6 black olives packed in brine (you'll want the sweet variety), 1/2 cup finely sliced mushrooms, 2 ounces finely sliced ham, shredded, and 1/4 pound shredded mozzarella. Spread the tomato and the mozzarella, arrange the other four toppings each in its quarter of the pizza; drizzle with a few drops olive oil and bake. Pizza Capricciosa: Everything in the house Not really, but it seems like that. It's usually the richest pizza offered, and every pizzaiolo makes it differently. This is based on the Pizzaria Giancarlo, outside Florence's Porta San Frediano. 1/2 cup tomato sauce or chopped canned tomatoes, 1/4 pound shredded mozzarella, 1 finely sliced hot dog, 1 link sweet Italian sausage (about 2 inches long), skinned and shredded, 8 thin slices salamino piccante (pepperoni in the AngloSaxon world) 2 ounces thinly sliced ham, shredded, 2 canned artichoke hearts, quartered. Spread the tomato sauce over the pizza, sprinkle the remaining ingredients over the sauce, drizzle with a few drops olive oil and bake. Pizza ai Quattro Formaggi: Cheese Galore! 1/2 cup tomato sauce or chopped canned tomatoes, 1/4 pound shredded mozzarella, 1/3 cup (each) shredded pecorino, gorgonzola, groviera (Swiss Cheese), and fontina or asiago, one black olive. Spread the tomato, and sprinkle it with the cheeses; the pizza will look almost white. Dot it with the olive and bake. Pizza alla Bismark: For reasons unknown to me a pizza with an egg cracked over it so it emerges from the oven sunny-side-up is called a Bismark. Excactly what else goes onto the pizza is up to the pizzaiolo, but ham goes quite well. So: 1/2 cup tomato sauce or chopped canned tomatoes, 2-3 ounces thinly sliced ham, shredded, and an egg. Spread the tomato sauce over the pizza, sprinkle the remaining ingredients over the sauce, crack the egg over the middle of the pizza, drizzle with a few drops olive oil and bake. Pizza Vegetariana: Again lots of variability, though the vegetables used are almost always cooked: stewed peppers, stewed eggplant, artichoke hearts, spinach, and what have you Begin with the standard 1/2 cup tomato sauce or chopped canned tomatoes and 1/4 pound shredded mozzarella, and go from there, adding the cooked vegetables you prefer. Drizzle with a few drops olive oil and bake. 5.Pair work. Find your own recipe of an Italian pizza. Make a project. Share your recipe with your group-mates. Part IV. COOKING. NATIONAL QUISINE Cooking equipment and methods Vocabulary of the text Clay oven – глиняная печь Cook tops – кухонные крышки Vessel – сосуд Frying pan - сковорода Sauté pan –чайник для соте Sauce pot -соусник Pressure cooker –кастрюля-скороварка Steaming – выпаривание Simmering – кипячение на медленном огне Poaching- варка а)яиц без скорлупы в кипятке, б) рыбы и т.д. в небольшом количестве воды Pan frying – обжаривание в миске ( кастрюле, сковороде) Metal grid – металлическая решетка Liquid propane - жидкий пропан Pit – яма, впадина There are many types of cooking equipment used for cooking. Ovens are one type of cooking equipment which can be used for baking or roasting and offer a dry-heat cooking method. Different cuisines will use different types of ovens, for example Indian culture uses a Tandoor oven is a cylindrical clay oven which operates at a single high temperature, while western kitchens will use variable temperature convection ovens, conventional ovens, toaster ovens in addition to non-radiant heat ovens like the microwave oven. Ovens may be woodfired, coal-fired, gas, electric, or oil-fired. Various types of cook-tops are used as well. They carry the same variations of fuel types as the ovens mentioned above. cook-tops are used to heat vessels placed on top of the heat source, such as a sauté pan, sauce pot, frying pan, pressure cooker, etc. These pieces of equipment can use either a moist or dry cooking method and include methods such as steaming, simmering, boiling, and poaching for moist methods; while the dry methods include sautéing, pan frying, or deep-frying. In addition, many cultures use grills for cooking. A grilloperates with a radiant heat source from below, usually covered with a metal grid and sometimes a cover. An open bit barbecue in the American south is one example along with the American style outdoor grill fueled by wood, liquid propane or charcoal along with soaked wood chips for smoking. A Mexican style of barbecue is called barbacoa, which involves the cooking of meats and whole sheep over open fire. In Argentina, asado is prepared on a grill held over an open pit or fire made upon the ground, on which a whole animal is grilled or in other cases smaller cuts of the animal.

Read it and put thew sentences 1-10 below in the correct order to make a summary of the process. Chocolate comes from cocoa beans, which are the seeds of the cacao tree. The cacao tree was originally cultivated by the Mayas and Aztecs over 3000 years ago. It was brought to Europe by Cortez, who had been introduced to the drink in Mexico, at the court of the Aztec ruler Montezuma. The word “chocolate” comes from the south American word “xocoatl” which means “bitter water”. It was prepared similarly to the way in which we process cocoa beans today. After being harvested, the cocoa pods were left to ferment and split open. Next, the beans were removed and left to dry in the sun. The dried, shelled beans were roasted in clay pots and then ground to a paste with a stone called a metate over a small fire. The paste was mixed with spices, then shaped into small cakes or loaves before being dried in the sun. the dried cakes were broken up, melted with hot water and maize, then beaten with a small wooden beater or molinet until frothy. The chocolate was then ready to drink. 1. The paste was made into small cakes. 2. The pods were left until they burst open. 3. The chocolate was drunk. 4. The cakes were mixed with water. 5. Flavourings were added to the paste. 6. The beans were left to dry in the sun. 7. The cakes were left to dry in the sun. 8. The roasted beans were ground to a paste. 9. The pods were collected. 10.The dissolved chocolate was beaten. Japanese Cuisine Clear broth with three cubes of tofu, shitake mushrooms and two rings of scallion green; a few slices of raw fish beautifully garnished and standing alone on a plate; a small dish of pickled cabbage, spare and clean to the palate; this is the uncluttered art of Japanese cooking. Zen Buddhism, Japan’s predominant religion, frames Japanese cuisine through Kaisek, the Zen way of cooking, which embraces nature, harmony and restraint. Flavors are celebrated in their simplicity, unencumbered by heavy sauces or complex mixtures. Sashimi, thinly sliced raw fish, epitomizes this. As fish meets tongue, its cool texture and light flavors create a sensuous culinary experience. In order to produce dishes that harmonize with their environment, a meal’s primary ingredients are always seasonal and local. Many foods are left raw or only slightly cooked to maintain and highlight their freshness. The spare and elegant presentation of food in many different types of dishware, and the ambiance of a classic Japanese restaurant, all conspire to create an oasis of calm. As in Korean cooking, rice, fish and pickles provide the base of most meals. The Japanese diet gets the bulk of its protein from soybeans and seafood, and so is perhaps one of the healthiest of national cuisines. Though red meat is a relative newcomer to the cuisine and outrageously expensive, beef, and the more reasonably priced pork, has been integrated creatively into Japanese cuisine. Compared with the West and other parts of Asia, are light and cooked with very little oil. The Japanese eat with chopsticks and drink soup directly from the bowl. A main course, say a grilled fish and a salad is filled out with rice, soup, pickles and tea. The Japanese are very particular about their rice, eating only native born medium- grained rice. However, this standard is becoming harder and harder to maintain as the population increases. Noodles are extremely popular as well, with entire restaurants specializing in them. Full-course Japanese cuisine has three traditional types, “honzen ryori”, an assortment of dishes served on legged trays at formal banquets, “chakaiseki ryori”, served before the tea ceremony and “kaiseki ryori”, party dishes, often served at “ryotei (high-class Japanese restaurants)”. Also “osechi ryori”, served on important feast days like New Year and “shojin ryori”, Buddhist vegetarian dishes. The main ingredients in Japanese cooking are seafood, vegetables and rice. Raw seafood cut with a very sharp knife has long been a distinguishing feature of native cuisine. Principalsonizgsre fermented soybean and rice products, such as “shoyu (soy sauce)”, “miso (soybean paste)”, “sake”, vinegar and “mirin (sweet sake)”. To preserve the natural flavors of ingredients, strong spices are avoided in favor of milder herbs and spices, such as “kinome (aromatic sprigs of the tree known as sansho)”, “yuzu (citron)”, “wasabi (Japanese horseradish)”, “myoga (ginger)”, and dried and ground “sansho” seeds. Food is arranged on plates or in bowls in a manner that harmonizes colors and textures that accord with the season of the year, for example, glass and bamboo are considered appropriate for summer.Contrasting shapes, sizes and patterns are used to achieve an aesthetic balance between food and receptacles in order to please the eye and stimulate the appetite. Japanese cooking characteristically tends to assimilate foreign recipes. Selection and rejection of ingredients has resulted in Japanese style Western and Chinese cooking. “Dashi (a soup stock)”, made with “kombu (seaweed known as sea tangle)” and “katsuobushi (dried bonitofillet)” shavings, is the basis of all Japanese cooking. First, about 30 grams (1 oz) of “kombu” in a liter of water is brought to the boil over a medium flame. The “komubu” is removed just before it boils and a small amount of water and about 30 grams (1 oz) of bonito shavings are added. When it boils the pot is removed from the flame and the surface is skimmed off. After the bonito shavings have sunk to the bottom, the contents are strained through cheesecloth. Stocks made from fish or chicken bones, “niboshi (dried sardines)”, or “kombu” and dried mushrooms are also used. Powdered instant stock is also widely utilized. Once known in the west either in the form of “sukiyald” or the more exotic “sushi,” Japanese cuisine has in recent years become much more familiar and appreciated around the world. Many visitors to Japan will have already sampled the pleasures of raw fish or batter-fried shrimp. But few first-time visitors to Japan are prepared for the variety and sumptuousness of Japanese food, as it is traditionally prepared. Eating in Japan is an experience to be enjoyed and remembered fondly for the rest of your life. Sukiyaki is prepared right at the table by cooking thinly sliced beef together with various vegetables, tofu and vermicelli. Tempura is food deep-fried in vegetable oil, after being coated with a mixture of egg, water and wheat flour. Among the ingredients used are prawns, fish in season and vegetables. Sushi is a small piece of raw seafood placed on a ball of vinegared rice. The most common ingredients are tuna, squid and prawn. Cucumber, pickled radish and sweet egg omelet are also served. Sashimi is sliced raw fish eaten with soy sauce. Kaiseki Ryori is regarded as the most exquisite culinary refinement in Japan. The dishes are mainly composed of vegetables and fish with seaweed and mushrooms as the seasoning base and are characterized by their refined savor. Yakitori is made up of small pieces of chicken meat, liver and vegetables skewered on a bamboo stick and grilled over hot coals. Tonkatsu is a deep-fried pork cutlet rolled in breadcrumbs. Soba and Udon are two kinds of Japanese noodle. Soba is made from buckwheat flour and Udon from wheat flour. They are served either in a broth or dipped in a sauce, and are available in hundreds of delicious variations. Ukrainian cuisine Ukrainian dishes show a sophisticated simplicity based on pleasing combinations of fresh, pickled, and smoked ingredients. While cooking techniques are not complicated, dishes may contain a great number of ingredients and unusual combinations, such as shuba salad which combines pickled herring and beets. Food is neither highly spiced nor bland, but skillfully seasoned to perfection. Bread, is of course the mainstay of the Ukrainian diet. The country’s reputation as the “breadbasket of Europe” is well deserved. The French writer Honore de Balzac, who lived in Ukraine for four years, counted 77 different ways of preparing bread. It is such a central part of the diet here that there is a custom to give honored guests and departing or arriving travelers the gift of a loaf of bread and salt. This tradition is still used in welcoming ceremonies for dignitaries and other important persons. Another staple of Ukrainian diet is kasha or what would be called “mush” in America and “porridge” in Britain. Borshch is certainly the national dish of Ukraine, even making its appearance on the menus of Chinese and Italian restaurants in Kyiv. This uniquely Ukrainian soup has been adopted by other countries in the region, but as recently as 45 years ago it could not even be found in restaurants in other Soviet republics. The many versions of borshch served throughout the country reflect the individuality of Ukrainians as well as their ingenuity. The beet-based soup can contain as many as 20 different ingredients, depending on the season, region, and of course, personal preference of the cook. It can be meatless or prepared from a rich meat stock and contain either beef or smoked pork. The availability of ingredients for traditional cooking are often dependent on the season, so most varieties of vegetables sometimes make their appearance in certain dishes in their pickled form. You also might find that certain dishes listed on a menu might not be available at certain times of year. Salads are very common, but rather than being lettuce-based, combinations of fresh, cooked, and preserved vegetables may be mixed with meat, cheese, or fish. With so many different recipes, the only constant of Ukrainian salads are the presence of vinegar or mayonnaise. Varenyky are dumplings made from boiled or fried dough, resembling ravioli without red sauce. They can be filled with meat, potatoes, cabbage, and sometimes mushrooms for as an entrée, or sour cherries or sweetened cottage cheese and raisins as a dessert. Any kind can be accompanied by butter or sour crčme. The word holubtsi can be translated into “little pigeons,” but really has nothing to do with fowl of any kind. They are cabbage rolls stuffed with meat and rice or buckwheat and often covered with a thin tomato sauce. There are many different kinds of pastries and cakes, usually less sweet than they are made outside of continental Europe. A tort Kyivskiy is a local specialty, made of layers of crumbly raised wafers, hazelnuts, and it even comes in its own special green box. For a uniquely Ukrainian drink, try kvas, a slightly sweet non-alcoholic beverage with a wheat-like taste sold from giant tanks on wheels in the summer throughout the city.

The United Kingdom Cooking Most meals would have been some form of stew, soup or pottage cooked in a cauldron over the central hearth of the house. Bread, baked in a clay oven or on a griddle, would also be a daily foodstuff. Flour could be ground at a water mill although more usually it would be done in the home using a hand quern. Wealthier people would have been able to afford an imported rotary quern from the Rhineland. When the flour is freshly querned from recently cut grain, little yeast is necessary to be added to the dough as there is a reasonable yeast content in fresh grain. Most of the time, especially amongst the poor, meat would only be used in small quantities to give extra flavour. This did not mean that Saxons were vegetarians, in fact they would eat as much meat as they could afford to. The wealthier a person was, the more often meat would figure in their diets. The vegetables used in cooking would have been those that were in season at the time, although some may have been preserved by drying or pickling. Similarly, meat would have been used more in summer and autumn when domestic animals were killed and game was more readily available, although pigs, sheep and cattle were killed during the winter to provide fresh meat and save too much depletion of winter fodder. When the animals, especially pigs, were killed the blood was probably collected to make a form of black pudding. This is made by stirring the blood until it is cool to stop it congealing and then adding flour and herbs. The animal fat was used both for cooking and to make tallow for lamps and dubbin. Meat was preserved by salting and smoking and some may have been dried. No doubt herbs and spices were used to disguise the unpleasant taste that these may have had. Fish as was said earlier could be preserved by salting, smoking, pickling or simply drying. Milk would have been used to make butter and cheese, especially sheep's and goat's milk. Eggs from chickens, ducks and geese would also have been eaten although the fowl of the period would not have laid as often as their modern counterparts. One of the most important foodstuffs was honey as this was the only sweetener available. A good hive could produce about 100lbs of honey in a year. (A family of 6 would require about 1/2lb honey per day.) Sweet foods like honey and almond cakes were popular, but usually not an everyday foodstuff. There is some suggestion that gingerbread and cheeseckes may have been fare on the Anglo-Saxon table, but the only references that still exist imply that these are introductions that occur later in our history. Sugar, whilst used in North Africa, was not much used in Europe. If it ever found it's way to Britain, it makes one wonder what it may have looked like by the time it reached our damp shores....... Other methods of cooking used included; frying in a frying pan or griddle (similar to a chestnut roaster), baking in a clay or turf oven, grilling on a spiral griddle, hanging griddle or on a 'barbecue' (similar to that shown on the Bayeux Tapestry). Spit roasting was done on a large rotary spit or using small skewers like a kebab skewer or food could even be baked in the embers of a fire usually wrapped in leaves and clay. By and large though, food was almost always boiled in a cauldron or baked in the embers of a fire usually wrapped in leaves and clay, as it was a more economic way of providing well cooked nutritious meals. Specific evidence for banquets and feasts comes from the court of Charlemagne where he is described as being served 'in four courses only, exclusive of the roast, which hunters brought in on spits' (Eginhard 'Early Lives of Charlemagne' Ed A J Grant). As to whether Charlemagne was being deliberately restrained is unknown. Some experts believe that later in the period, banquets and religious feasts held by the nobility (and sometimes the lower ranks too), would have as many as ten or twelve courses/dishes, although each course was fairly small. Fish and meat would make up several of the courses, although some courses would be purely vegetable. Much alcoholic drink was also served at banquets. There is some suggestion that the finds of large cauldrons from a variety of sites were almost always used for brewing beer, and not for cooking porridge etc; indicating the status of such beverages in their society. An honoured guest would be served drink by the banquet giver's wife and/or daughter or the banquet host if they happened to be a woman. Food was eaten from wooden or clay bowls using only a knife and spoon (forks do not seem to have been used for eating until much later in the medieval period). There are however Scandinavian finds of pointed 'food sticks' made of wood or bone which may have been used for picking up pieces of meat and larger vegetables. Wooden plates were used for some food although pottery ones are very rare. Drinking vessels were made from a variety of materials in a number of styles. The commonest would have been wooden or pottery cups and mugs. Horns (often highly decorated) were also used and conical glass vessels were used in the early period, but were rare, giving way to glass vessels shaped more like beakers that we have today. Small wooden cups were used for very strong drinks. Leather was also used for drinking vessels although there is little evidence of this other than a passage in Ælfrics Colloquy. There is no evidence for drinking vessels with handles ever being used. Drinks were served from pottery jugs and pitchers or from bottles made of wood, clay or leather. Wooden tubs and ladles were probably used for serving drinks, some of which were served hot. English Food English food seems to have two distinct faces in the American culinary imagination. The first is the decidedly grey image of boiled meat. Indeed, boiled meat may be the paradigmatic emblem of loathed English blandness. The other face of British food, is perhaps best described as the great British flair for the pageant of the meal. High tea served in an oak-paneled room, where rich fabric, antique porcelain, and mountains of cakes and clotted cream sparkle in reflection from the mirror-polished side of a sterling silver tea pot; the picnic by the bank of the Thames; the white cravatted public school boys on their way to an evening meal in some Gothic-vaulted dining hall. Still, the stuff of the meal itself, the food of England, is not nearly as awful as some make it out to be. With its double creams, rich puddings and straightforward flavors, it can be quite marvelous. One point must be made clear: for centuries the English aristocracy ate French food, and their menus are peppered with accents graves and circumflexes. To compare boeuf à la bourguignonne to the Scottish haggis is to compare apples and oranges, haute cuisine to the invention of necessity. This is not to say that there aren't distinctly British tastes that cross class lines. There are. One is a love for the first meal of the day, another is a taste for meat. The British butcher wears a white smock and a straw boater. Perhaps his most important job has been to prepare the great roast beefs that anchor the traditional Sunday lunch feast. Roast beef is the national culinary pride. It is called a "joint," and is served at midday on Sunday with roasted potatoes, Yorkshire pudding, two vegetables, a good strong horseradish, gravy, and mustard. The leftover joint could feed the family until Friday (traditionally fish day), recooked in a curry, pie, stew, or fried with cabbage, onions, and potatoes into the onomatopoeic "bubble and squeak." Beef is big industry in England, and the Aberdeen Angus is one of her famous beef-producing breeds. Dairy cattle are also farmed extensively -England is famous for its creams and butters and for its sturdy and delicious cheeses: Stilton, Cheshire and its rare cousin blue Cheshire, double Gloucester, red Leicester, sage Derby, and of course cheddar. Lamb and mutton are the second most-widely consumed meats followed by pork, farmed mostly in Ireland, at a distant third. Game has always had a central role in the British diet. This reflects both the abundant richness of the forests and streams and an old aristocratic prejudice against butchered meats. Formal feasts were built around venison, rabbit, and game birds. This preference can still be seen today on the menus of good English restaurants. Being an island makes fishing easy for the Brits. Fish are central to the English diet. Many species swim in those cold waters: sole, haddock, hake, plaice, cod (the most popular choice for fish and chips), turbot, halibut, mullet, John Dory. Oily fishes also abound (mackerel, pilchards, and herring) as do crustaceans like lobster and oysters. Eel, also common, is cooked into a wonderful pie with lemon, parsley, and shallots, all topped with puff pastry. The English are justifiably famous for their gardens, and the kitchen garden has long been a source for herbs and vegetables. But much of the flavoring in British cooking comes from further horizons than the garden out the back door. The Brits have long incorporated exotic spices. When the Frankish Normans invaded, they brought with them the spices of the east: cinnamon, saffron, mace, nutmeg, pepper, ginger. Sugar came to England at that time, and was considered a spice -- rare and expensive. Before the arrival of cane sugars, honey and fruit juices were the only sweeteners. The few Medieval cookery books that remain record dishes that use every spice in the larder, and chefs across Europe saw their task to be the almost alchemical transformation of raw ingredients into something entirely new. Throughout northern Europe, elaborate concoctions of mixed meats and offal (almond flour thickeners), spices, raisins, and other dried fruits were the result...and to the credit of the successful chef, there was often no chance that any of the discrete, original flavors could be recognized. Spices were of course a handy way to mask slightly off meat. There is, in fact, a rule of Victorian etiquette that deems it less than polite to sniff at meat when it is on the fork. The affair with the spices of the East has continued, even to this day, and can be seen preserved in the tastes of the early American colonists, and in the caraway-, ginger-, and mace-laced cakes that grace the tea table. In this vein, the Brits have proven exceptionally good at condiments: strong mustards, horseradish, chutneys, vinegars, marmalades and jams, curries, even Worcestershire sauce. Now, the cynical may still say it's a good thing the English have worked so hard at that which covers food. But, for a moment, imagine the perfect cup of tea accompanied by scones, with clotted cream and strawberry jam, a juicy slice of beef with a dollop of strong horseradish, or the perfect piece of Scottish smoked salmon, and you just may find your mouth watering at the thought of what the British have brought to the table. Fruit and Vegetables When we visit the shops in England today, we are presented with a wealth of fruit and vegetables from all corners of the planet from which to choose. For people in this country in the tenth and eleventh century this could not happen. They had only such foods as could be cultivated seasonally or found wild. Exotic foods such as potatoes, tomatoes, bananas, pineapples - fruits and vegetables of the New World, were unknown here. Mediterranean fruits, such as lemons and oranges were, as far as we know, not imported, although we have documentary proof for the importation of such things as figs and grapes (Viking Age England, Julian Richards, p94). We know that they grew wheat, rye, oats and barley. Wheat for bread, barley for brewing and oats for animal fodder and porridge. Along with these crops grew various weeds of cultivation - some of them poisonous. The harvesting methods made it difficult to separate the cereal from the weed, and many illnesses must have been caused in this way. It is known that they had carrots, but these were not the large, orange coloured vegetables that we are used to today. They were much closer to their wild ancestors - purplish red and small. 'Welsh carrots'; or parsnips were also availablae (S Pollington - 'Leechdom'). Cabbages were also of a wild variety, with smaller tougher leaves. They cultivated legumes such as peas and beans. Various 'wild'; roots were probably collected, such as burdock and rape. Onions and leeks were cultivated as flavourings and wild garlic may have been used. One way in which the people made up for the poor quality of these vegetables would have been to flavour them with native and imported herbs and spices. In Aelfric's Colloquy, the merchant speaks of importing spices, and in the Leechbooks, some imported spices are mentioned. Among them may have been ginger, cinnamon, cloves mace and pepper. We have no way of knowing how these spices were used , as the earliest recipe book only dates from the 14th century. Home grown herbs would have included coriander, dill, thyme, opium poppy and summer savoury. (Eighth-Eleventh Century Economy and Environment in York in J Rackham Environment and Economy in A/S England. CBA Res Rep 89.) Many fruits were eaten and seeds from excavations tell us that they also had small apples (crab apples) plums, cherries and sloes. A large deposit of apple pips, from a pit in Gloucester probably points to the making of cider. These would have been sweetened with honey. Sugar was virtually unknown in the West of Europe, and at this period was used only as a medicine, as a laxative and for bladder disorders, for the kidneys and for eye disorders. (Dangerous Tastes, the Story of Spices. Andrew Dalby). It does not. however, appear in any Anglo-Saxon Leechbooks. Honey was used to make a sweet alcoholic drink called mead, which was usually flavoured with some form of herb such as meadowsweet (O.E. meduwyrt - meaning mead plant). However, even today it is still not clear whether the mead they knew was no more than honey beer that we may encounter occasionally today. The confusion here lies with the fact that they refer to 'frothing horns of mead', and mead as we make it does not have a head to it. Barley was used to make beer which may have been flavoured with wild hops. Whether these were wild or cultivated is not known, but the Graveney boat, a 10th Century clinker built inshore trading boat may have been carrying a cargo which included hops up the Thames Estuary. (The GraveneyBoat: a tenth century find from Kent. V Fenwick ed Brit Archaeol Re Brit Ser 53 Oxford 1978). Wine was drunk, but this was generally imported although fruit wines may have been home-produced. There are also written references to 'apple-wine', probably a form of cider. Many fruit juices including apple, pear and plum were drunk as were herbal 'teas' and infusions. Whilst acorns are plentiful most years, they can only be eaten with sufficient preparation. There is no mention in the Anglo-Saxon record of them ever being used as a food stuff - with the closest instances of Oak 'products' being the leaves as a remedy in the Ormont fragment and the bark as an astringent in Bald's Leechbook. There may have been many instances where a needs must approach may have occurred which was not normal practice when food was in short supply. Evidence of such practices has been observed at sites where grain was used for bread production, but the bulk inclusion of random grass seeds suggests that the flour was being padded out - either to make it stretch further because there was actually little wheat, or simply because someone was being ripped off. Spirits and fortified wines were not known although the apple wine may have had quite a high alcohol content. Christmas Cake Recipe 225 grams / 8 oz of butter 280 grams / 10 oz of soft brown sugar 6 eggs 350 grams / 12 oz of flour 2 teaspoons of baking powder 1 tablespoon of mixed spice 2 teaspoons of cinnamon 1 teaspoon of nutmeg 225 grams / 8 oz of raisins 225 grams / 8 oz of currants 450 grams / 1 lb of sultanas 115 grams / 4 oz of mixed peel 115 grams / 4 oz of whole almonds 115 grams / 4 oz of glacé cherries (red and green) grated rind (zest) of 1 lemon or orange 4 teaspoons of sherry or brandy Preheat the oven to 120°C, 250°F or gas mark ½. Line a large cake tin with a layer of tinfoil followed by a layer of cooking paper. Weigh and measure all the dried fruit into a large bowl and mix thoroughly. In another large bowl cream the butterand sugar, add the eggs beating through one at a time. Sift the dry ingredients into the creamed mixture. Add the dried fruit and zest (rind) and lastly add the sherry or brandy. Pour into the lined cake tin and bake for 3½ to 4 hours. To test if the cake is cooked, poke a cake tester or skewer into the middle of the cake. If it comes out clean the cake is cooked. Leave one hour before removing from the tin. The alcoholic content of the sherry or brandy will evaporate during baking, but you may prefer to use fruit juice instead. Once the cake has cooled, ice with Almond Icing or Marzipan and Royal Icing. The cake is best made a month or more in advance to let the flavours develop and should be stored in an airtight container. Sponge Cake Recipe 4 eggs ¾ cup of castor sugar 2/3 cup of plain flour 1/3 cup of cornflour 1 teaspoon of baking powder Preheat oven to 170°C, 340°F or gas mark 3½. Break the eggs into a mixing bowl and beat with an electric beater until thick and creamy (around 5 to 8 minutes). When you run a spoon through the mixture, the mark shouldn't disappear. Gradually beat in the sugar until fully dissolved. Sift the dry ingredients repeatedly into a separate bowl to ensure that they are thoroughly mixed. Lightly and quickly fold the dry ingredients in with the eggs and sugar using a metal spoon ensuring that the airy sponge mixture is not broken down, but also that the flour is properly mixed in. Pour evenly into two well-greased and lined 20 cm / 8 inch round cake tins. Bake for 20 to 25 minutes. The cake is cooked when it shrinks slightly away from the side of the tins. Turn out of each tin onto a cake rack immediately. Fill with cream, or buttercream icing, and top with your favourite fruits, and/or grated chocolate. Variations: Chocolate - take out 2 tablespoons of flour and add 2 tablespoons of cocoa. Coffee - add 3 teaspoons of instant coffee dissolved in a little hot water.

Russian dishes are easy to cook and they do not demand much skill and special ingredients, they do not need exotic equipment and tool and everybody who knows how to hold a cooking knife and how to peel potatoes can cook delicious Russian dishes. A few words about Russian cooking traditions. In old Russ, grain - that is rye, barley, oats, millet and wheat - was always the main food product. Since days of old the Russians have been known as landtiller. That is why bread remains their major national food. Pies have always been a par of the holiday fare. The pies are customarily filled with different kinds of meat, fish, and berries. As for the groats, millet was most often used since it was the main agricultural product. They also made various kinds of kashas (cereals), round loaves, baked puddings, and krupenik. 4. Put down the nouns. Translate the words.

Read the microtext and define the main idea of the text. Russians have always eaten vegetables. In old times it was the turnip, cabbage, radish, and cucumbers. Since the 18th century the potato began to play an ever more important part as one of the most loved ingredients of the Russian board. The abundance of berries, mushroom, and honey in Russian cuisine is accounted for by the country's vast expanses, especially in the north. One more important thing should be mentioned for better understanding of Russian cooking traditions. Russia is an Orthodox country and all the feasts were always strictly followed. Totally there are more than 200 days in a year in which the Orthodox Christians should avoid eating meat, milk and milk products (including butter), eggs. That is why Russian cuisine widely uses vegetables, fish, berries, and mushrooms. In order to cook tasty dishes using just vegetables it is necessary to use different spice, Russians used dill, parsley, celery, later they used spidery which were delivered from other countries - pepper, cinnamon, cardamom, cloves. Nearly all dishes include onion. 7. Arrange the words in the order of appearance in the text. abundance feasts two hundred dill berries century 8. Complete the sentences. In old times….

Author tested all these recipes and some of them are often used in everyday cooking. In general each cuisine roughly can be divided into two groups of dishes official dishes and every-day dishes. The same is with Russian cuisine. Official dishes demand much time for cooking, often they include many different products. So in the end these recipes are Russian only by name, something like "Pork with Russian sauce", "Russian cutlets" etc. In opposite the every-day dishes that are cooked of common products and in limited time range reflect the real Russian cuisine and they give the real impression about Russian cuisine. Here are recipes of so-called every-day Russian cuisine.

The rivers, lakes and seas by which Russian people settled always gave them this tasty and accessible food. Apart from fresh-water fish our ancestors also ate sea fish like cod, navaga. However, especially valued were sturgeon, salmon and other fishes of this kind. Most often fish dished are served with potatoes and boiled buckwheat. There is one explanation why in past Russians used to cook fish dishes. It was not allowed to eat any kind of meat and any kind of milk food in duration of long fasts but fish dishes were permitted (except time of the Lent). 11.

Geographically it is situated at the intersection of the European and Asian civilizations. Despite frequent invasions by enemies, Georgian people have managed to preserve their distinctive culture. From the earliest times Georgia was divided into various provinces that today are called economic regions: they are the Central-Eastern, Eastern, Southern, and Central-Western regions. Georgians themselves divide their country into Eastern Georgia and Western Georgia. Homes, way of life, customs, and culinary traditions of cooking some national dishes are quite different in these two regions of the country. However a most fertile and original Georgian cuisine has kept its national peculiarity, but with some distinct differences in the art of cooking between Eastern and Western Georgia. Their common feature is the utilization of wine and spices. These two ingredients are part and parcel of any meal. As for the rest of the ingredients they differ considerably. For example in Western Georgia, bread and various round flat cakes made from maize flour (“mchadi”) are widespread. In Eastern Georgia they prefer bread made of wheat flour. In some parts of Western Georgia such as Megrellin and Abkhazia, they use a sort of millet (“chumiza”) as bread. They put millet into a pan and cook gruel (“gomi”), after which they eat it with soups, meat, and vegetable dishes. In the eastern region of Georgia, along with traditional beef, people eat mouton and lots of fat. At the same time in the west of Georgia they eat less meat and prefer poultry. Nevertheless all these differences are not sufficient to mark the border between Eastern and Western Georgian cuisines. It is important to mention that Georgian cuisine can be distinguished by its simplicity of cooking technology. Further, there are not any religious or cultural restrictions imposed on choosing a type of meat because for long time the Georgian nation developed at the intersection of many cultures and traditions. In general Georgian cuisine does not favor one kind of meat over another. Georgian meat courses can be cooked from pork (“muzhuzhi”), mouton (“chanakhi”), beef (“kharcho”), and poultry (“chakhokhbili”). Yet this tolerance of all types of meat yields to beef and poultry. For example “kharcho” soup is made only from beef, rice, and walnuts as the basis of its special sour broth (“tklapi”) prepared from plum, and it looks like a thick cream soup. A combination of soft beef broth, neutral rice with a natural sour “tkapi” taste, herbal spices, and the peculiar aroma of nuts provides for the specific flavor and smell of “kharcho” soup. As for “khash”, it is made from pig legs. They drink this broth with garlic and black pepper in the morning before daybreak. As Georgians say “khash” is an especially good “medicine against a hangover”. In general Georgian soups are very thick because of added egg yolks and they are cooked without vegetables. Various sorts of meat are also widely used for cooking main courses. In Georgia they often grill meat on a spit (“mtsvadi” is the equivalent of Russian shashlyk or barbeque). They take a washed piece of meat, put it length-wise on a spit, then grill it over charcoal and keep it turning. Only 10 minutes before it is ready they sprinkle it with salt, pepper and spices. Poultry is usually cooked in its plumage. They take a cleaned bird, salt it inside and coat it with soft clay. In that way the bird is cooked in its own juices. After 40 minutes they break down the clay and remove it together with the plumage. Very broad metal pans (“tapa”) are typical of the Georgian way of cooking, which are used for the preparation of meat dishes especially for frying poultry under pressure. This method was borrowed from the Armenian cuisine, and its usage became even more wide spread in Georgian cuisine. This technology as many other methods contribute to the national culinary art of Georgian cuisine. In Georgia, fish takes a considerably inferior place in comparison with meat. The majority of fish courses are cooked from the barbell, carp, and trout species inhabiting only some parts of the country. Mainly Georgian’s consume boiled or stewed fish. Vegetable dishes have a significant place in Georgian cuisine. The majority of these dishes are made from haricot beans, eggplants, cabbage, beetroot, and tomatoes. In addition, they eat nettle, mallow, and young leafy tops of root vegetables such as cauliflower. Vegetables can be eaten raw, boiled, roasted, fried, stewed, salted, and marinated. One more peculiarity of the Georgian table is its various, and plentiful consumption of cheeses. Cheese is part and parcel of Georgian cuisine. The content of cheeses is very specific here. In general it is salt cheese prepared in a jug or in a water-skin. We must mention the differences of tastes in Western and Eastern Georgia. The West specializes in producing plain, tasteless cheeses with a sour milk flavor (“suluguni” and “imeretinskiy”). Suliguni is a layered sort of cheese in the shape of a round cake, “imeretinskiy” cheese is similar to the latter but without layers. Eastern Georgia specializes in producing salty and spicy cheeses such as “kobiyskiy”, “tushinskiy”, “georgian”, “guda”, “chanakh”, and “osetinskiy”. In Georgia the way cheese is consumed is also very peculiar. It is not used as an ingredient which is typical of European cuisine. It is generally used as the main ingredient for hot, main courses. In Georgian they prepare cheese by boiling, boiling in milk, charcoaling on a spit, frying, baking in pastry, soaking, mashing, and by flavoring with oil and spices. This tradition of cheese preparation is connected with the fact that Caucasian cheeses do not go through a complete process and very often represent only a half-finished product. The number of Georgian dishes which contain cheese as an ingredient exceeds several hundreds. But, perhaps, one of the most favorite and universally recognized dishes for all Georgians is “khachapuri”, which is a type of a pie prepared with various kinds of cheese. Quite often this national cuisine uses such nuts as filbert, almonds, hazel nuts, beechnuts, and most frequently walnuts. A walnut is an invariable component in different seasonings and sauces. Nuts are perfectly suited for meat dishes as well as for vegetable and fish dishes. Nuts are added to soups, confectionary, salads, and main courses. On the whole it is impossible to imagine a Georgian table without nuts. Spicy herbs play a significant role in Georgia. They use spices all year round. They serve them for breakfast, lunch and dinner. Depending on the season it can be parsley, dill, damsons, mint, basilica, savory, or many other greens growing in Georgia. Foetus, leaves, stems, bark, roots, and inflorescence can be used as spices. All spices can be either freshly made or dried. Further, the aroma spices contain great amounts of wholesome substances, for example, minerals, salts, iron, phosphorus, volatile oils, aminoacids, fructose, and many others. Who knows, maybe herbs in particular, hold the secret of health and longevity for Georgians. One of the most essential and distinguished culinary traditions in Georgian cuisine is the appliance of sauces in order to enrich and diversify the main course. One and the same dish served under different sauces is distinguished from the alike in regards to its appearance, flavor and aroma. Bright-colored sauces decorate and complete the dish. Georgian sauces fundamentally differ from the sauces used in other national cuisines regarding both their composition and cooking technology. In Georgia sour berry and fruit juices are used as a foundation for making sauces. The base is usually made of pomegranate, blackberry, and tomatoes. Sauces made with a foundation of ground nuts are also very popular. Then the base is flavored with a range of spices and herbs. The tradition and culture of wine manufacturing is inseparably linked to the history of Georgia. Viticulture is one of the oldest and most respected branches of agriculture of Georgia. From generation to generation Georgians cultivate vineyards keeping family recipes. That is why Georgia has kept its great diversity of wines. Nowadays Georgian vineyards breed over 500 grape species. The culture of wine making, which entered family lives of Georgians many years ago, imprinted the culture of consuming strong drinks. Every lunch is accompanied with wine. During the working days Georgians usually drink 2 or 3 glasses, which is quite moderate. In Georgia nobody, including poor people, can resist the opportunity to have a glass of wine before dinner. Genuine Georgian wine contains a lot of wholesome elements, which is why it is allowed for children. During holidays they drink more wine of better quality, during all big family gatherings around the table, or when guests pay their visits. However it is important to mention not only the quantity of wine consumed, but the quality and the culture of drinking. Strict order reins at the Georgian table. They choose a master of ceremonies (a toastmaster). Nobody has a right to propose a toast without the permission of the toastmaster. Normally the master of ceremonies proposes 25 toasts (250 grams each) to every guest during the ceremony that lasts for 5 hours. The record is 45 glasses and a 3-liter horn-shaped vessel consumed during one ceremony. The last glass of wine should be emptied because you “must not leave tears” to the owner of the house. There is a special holiday in Georgia devoted to vintage, which is called “Rtveli” and is celebrated in September. Everyone, even children gather grapes in special wicker baskets. Walls of houses are decorated with grape bunches. They make sweet foamy “madzhari” out of the first grade grapes. This wine is not aged but drunk as soon as it is ready. Must, which is left after making “madzhari”, and maize flour is used for cooking “pilamushi”. They also make “churchkhela” of grape juice and nuts. In the basement of every country house there is an area for wine storage (“marami”) containing several huge cone-shaped jugs (“kveri”) that are dug in the earth up to the neck. On the basis of manufactured wines Georgia can be divided into two zones: East and West. Kakhetia and Kartli belong to the Eastern zone. In Kakhetia they mostly cultivate white grapes such as rkatsiteli, and hikhvi. As for red grapes they produce saperavi and cabernet. Kartli specializes in such sorts of grapes as chinuri, aligaute, tavkveri, and gorouli. On the basis of this wine material they produce the mild wine “Tsinandali”; a rough, thick, strong wine “Saperavi”; a wine unsurpassed in regards to flavor and aroma called “Kindzmarauli”; an original wine, “Tesmani”; and a peculiar wine “Gurdgaani”. Imeretia, Megrelia, Guria, Adgaria, Racha-Pekhchumi, and Abkhazia belong to the western zone. In these districts they cultivate such grapes as tsitska, tsalikouri, krakhuna, alexanderum and others. Along with specific table wines they produce the material for champagne manufacturing, and wines such as “Khvanchkara” and “Tvischi”, which have gained a success similar to the table Kakhetian wines. In general they produce over 50 brands of table wine in Georgia. There are three methods of making white table wine: they are Kakhetian-Eastern (fermentation of must together with the pulp of grape skins and pits), Imeretinian-Western (fermentation of must partially adding the pulp), and European (fermentation of pure grape juice must without pulp). In Georgia, in compliance with the European method of fermentation they produce “Tsinandali”#1, “Gudgaani” #3, “Tsamkodri” #7, “Mikhranuli” #9, and “Napereuli” #27 as well as ordinary table wines such as #6.23. These wines have a soft, light, fresh taste with fruit flavor, 10-12.5% alcohol content, and are aged 2-3 years. On the basis of Kakhetian fermentation they produce wine “Kakhetinskoye” #8 and “Tibaani” #12. Their taste is full, soft, and harmonic. It is aged for 1 year and is 11.5-13% alcohol. On the basis of the Imeritian fermentation process they produce the “Sviri” wine. It has a harmonic and subtle flavor. When it is 2 years old, it is bottled. The ready- made wine is 1112.5% in alcohol content. Wines are divided into the sorted and blended catagories. Sorted wines are made from one kind of grape. Blended wines are made from different sorts of grapes. It is necessary to mention that Georgian wines are numbered and named after the territory from where they are produced, or numbered and named after the grape sort from which they are made. In addition to this in Georgia they produce table wines, semi-sweet wines, sweet wines, dessert wines, sparkling wines, vintage wines, and ordinary cognacs. It is remarkable of Georgia that people consume only limited amounts of strong drinks such as sweet liqueur or “chacha”. Liqueur is made of fermenting jam or different fruit, which are usually a little spoiled and are not good for eating. “Chacha” is a fruit home-brew, which is sometimes called vine vodka. Chacha is made of cake (grape residual left after making wine), fig, tangerine, orange, and mulberry. The method for producing chacha is the same as that for making Russian home-brew. Traditionally they drink chacha in small cups (25-30 grams). In Western Georgia chacha is accompanied with a sweet snack, in Eastern Georgia chacha is followed with a salted snack. Cognac manufacturing appeared in Georgia not long ago, in the second half of the 19th century. Despite its short history, Georgian cognacs have gained wide popularity. Georgian cognac is produced on the basis of cognac spirits (65-70% alcohol), in oak barrels where cognac gets its golden color, soft flavor, and aroma. Depending on its age and the grade of maturity they produce cognacs of 6 to 10 year old spirits and ordinary cognacs of 3 to 5 year old spirits. EXERCISES 1.

Cereal crops or grains are mostly grasses cultivated for their edible grains or fruit seeds (i.e., botanically a type of fruit called a caryopsis). Cereal grains are grown in greater quantities and provide more energy worldwide than any other type of crop; they are therefore staple crops. They are also a rich source of carbohydrate. In some developing nations, grain constitutes practically the entire diet of poor people. In developed nations, cereal consumption is more moderate but still substantial. The word 'cereal' derives from 'Ceres', the name of the pre-Roman goddess of harvest and agriculture. Grains are traditionally called corn in the United Kingdom and Ireland, though that word became specified for maize in the United States, Canada, New Zealand, and Australia. 7.

Other grains that are important in some places, but that have little production globally, include: Teff, popular in Ethiopia but scarcely known elsewhere. This ancient grain is a staple in Ethiopia. It is high in fiber and protein. Its flour is often used to make injera. It can also be eaten as a warm breakfast cereal similar to farina with a chocolate or nutty flavor.

Read and translate the text. Food value Cereal grains supply most of their food energy as starch. They are also a significant source of protein, though the amino acid balance, with exceptions as noted below, is not optimal. Whole grains (see below) are good sources of dietary fiber, essential fatty acids, and other important nutrients. Rice is eaten as cooked entire grains, although rice flour is also produced. Oats are rolled, ground, or cut into bits (steel-cut oats) and cooked into porridge. Most other cereals are ground into flour or meal, which is milled. The outer layers of bran and germ are removed. This lessens the nutritional value but makes the grain more resistant to degradation and makes the grain more appealing to many palates. Health-conscious people tend to prefer whole grains, which are not milled. Over consumption of milled cereals is sometimes blamed for obesity. Milled grains do keep better because the outer layers of the grains are rich in rancidity-prone fats. The waste from milling is sometimes mixed into a prepared animal feed. Once (optionally) milled and ground, the resulting flour is made into bread, pasta, desserts, dumplings, and many other products. Besides cereals, flour is sometimes made from potatoes, chestnuts and pulses (especially chickpea, which is known as bean). Cereals are the main source of energy providing about 350 kcal per 100 grams. Cereal proteins are typically poor in nutritive quality, being deficient in essential amino acid lysine. The proteins of maize are particularly poor, being deficient in lysine and tryptophan (a precursor of niacin). Rice proteins are richer in lysine than other common cereal proteins and for this reason, rice protein is considered to be of better quality. Rice is a good source of B group vitamins, especially thiamine. It is devoid of vitamins A, D, C and is a poor source of calcium and iron. Certain grains, including quinoa, buckwheat, and grain amaranth (Pseudo cereal, nongrasses), are exceptionally nutrious. Quinoa was classified as a "supercrop" by the United Nations because of its high protein content (12-18%). Quinoa contains a balanced set of essential amino acids for humans, making it an unusually complete source of protein in plants. In English, cold breakfast cereals, as opposed to cooked porridges such as oatmeal, are simply called cereal. 9. Pair work. Have a talk on the problems of food value and cereal value. Lesson 4 1.

All too often, cereal products are thought of as nothing more than starchy fillers, and indeed, when you consider how some commercial products like cakes and biscuits and breakfast cereals are made from over-refined grains with nearly all the nutrients except the starch extracted, and then loaded with fat, sugar, artificial flavourings etc., you might be forgiven for thinking that's true. But go back to the original, unrefined grains and you have a wealth of nutrients in a small package. Grains have been the staple foods of many civilizations for thousands of years. Wheat, barley, oats and rye in Europe, maize in America, quinoa in South America, rice in the East, and millet in Africa. Storage. Keep in airtight containers in a cool, dark, dry place. Whole grains can be stored for up to 2 years; flaked, cracked grains and flours should be used within 2-3 months of purchase. Sprouting. Whole grains can be sprouted, which greatly enhances their nutritional value, e.g. wheat grains, raw buckwheat and barley. 6. Word formation. Form words adding prefixes over-, un-.

What cereal products are grown in different countries? 5. How long can grains be stored? Lesson 5 1. Read the text and define the meaning of new words. Translate the text. Cooking Cereals can be used in other ways, besides being ground into flour for bread, cakes etc. Whole grains can be added to stews and casseroles, or cooked until soft. Cracked or kibbled grains are cut or broken pieces of whole grains e.g. kibbled wheat and bulgur wheat. Meal, a coarse kind of flour, can be used to make porridge, thicken soups or mixed with wheat flour to add interesting flavours and textures to ordinary breads, biscuits, muffins etc. Whole grains should be washed thoroughly. Boil the required amount of water, add the washed grain, stir once, put a tight-fitting lid on the pan and simmer for the required cooking time or until the liquid is absorbed. Turn off the heat and leave to stand for 5 minutes before removing the lid. 2. a) Cover the right column and read the English words.

Read the micro text and define the main idea of the text. Cereals are seeds of plants, usually members of the grass family but there are a few exceptions. They are annuals that are they have to be planted every year and at the end of the summer, when they have produced ripe seeds, they die down. Like all seeds, cereals are very nutritious because they contain all the nutrients the embryo plant needs to start growing. Unrefined cereals are valuable sources of proteins, carbohydrates, B vitamins and also contain some fat, iron, vitamin E and trace minerals and are a very good source of fibre in the diet. Some cereals (wheat, barley, rye and oats) contain the protein gluten, which is essential for leavened bread-making. Without sufficient gluten, bread will not rise. People suffering from gluten intolerance or coeliac disease must avoid any cereal containing gluten. In some parts of the world unleavened (unrisen) bread is eaten or the staple cereal is made into noodles or pasta. They are usually cheap to buy and are a valuable source of variety in the vegetarian diet. 4.

Read and translate the text: Barley Barley grows in a wider variety of climatic conditions than any other cereal. It used to be a very important source of direct human food, but its use has diminished over the last 250 years, replaced by wheat, and it is now used almost exclusively as animal feed or for making beer and whisky. It contains gluten, so barley flour can be made into bread. More usually found in the shops as whole or pot barley, or polished pearl barley, it is also possible to buy barley flakes or kernels. The whole barley is more nutritious with 100g providing 10.5g protein, 2.1g fat, 69.3g carbohydrate, 4g fibre, 50mg folic acid, 6mg iron and 50mg calcium. It can be cooked on its own (1:3 parts water for 45-60 minutes) as a pleasant alternative to rice, pasta or potatoes, or added to stews. Malt extract is made from sprouted barley grains. Buckwheat (gluten free) Buckwheat is not a true cereal as it is not a member of the grass family, instead being related to sorrels and docks. If you look at docks closely, you can see that the seeds, though smaller, have the same distinctive triangular shape. Buckwheat, a native of central Asia, is now grown in Europe, N America and the former USSR countries, but it is still not widely used in Britain. 100g of buckwheat provides 11.7g protein, 3.9mg iron and it is very high in calcium with 114mg per 100g. Available raw the seeds are greenish-pink, or roasted (known as kasha) the seeds are darker reddish-brown. It can be cooked (1:2 parts water for 6 minutes, leave to stand for 6 minutes) and served like rice or you can add it to stews and casseroles. Buckwheat flour can be added to cakes, muffins, pancakes etc. where it imparts a distinctive flavour. Look out too for buckwheat spaghetti, soba. Corn or Maize (gluten free) Maize is the principal food plant of America and was unknown in other parts of the world until Columbus reached America in 1492. It was grown by the Maya, Inca and Aztec civilizations, and by various North American Indian tribes and now has spread to Canada, USSR, Italy, Spain, Egypt, India and South Africa. It is used for human food, animal feed and as a source of raw materials for industry. 100g maize gives 9g protein. Fresh maize is often available (sweet corn, corn on the cob) but remember that nutritional values will be lower because less concentrated. We most often see maize as cornflakes or popcorn, but cornmeal or polenta is available and can be added to soup, pancakes, muffins etc. Tortillas are made from maize meal, as are quite a lot of snack foods. Do not confuse cornmeal with highly refined corn starch/flour, used for thickening. Millet (gluten free) Millet is the name applied to a variety of grasses first cultivated in Asia or Africa. It is a staple crop in Africa because it is drought resistant and keeps well. 100g millet provides 9.9g protein, and 6.8mg iron (higher than other cereals). Millet makes a delicious alternative to rice but the tiny seeds need to be cracked before they will absorb water easily, so they should be first sautéed with a little vegetable oil for 2-3 minutes until some are seen to crack, then add water with care (1:3 parts), bring to the boil and simmer for 15-20 minutes until fluffy. Millet flakes can be made into porridge or added to muesli and millet flour is available, sometimes also made into pasta. Oats Oats are thought to have originated in Western Europe and may originally have appeared as a weed in barley and so got spread with the barley. They're now grown in many parts of the world including N W Europe, the former USSR countries, North America, Canada, Australia and China. Used mostly as animal feed, they are very nutritious. In fact, as they are usually inexpensive to buy, they can be a real boon to people trying to get a good diet on a low budget. 100g oats gives 13g protein, 55mg calcium (more than any other cereal except buckwheat), and 4.6mg iron. Available as groats (whole grains with the husks removed) but more usually as various grades of oatmeal, rolled oats or jumbo oat flakes. Oat groats need cooking for 45 minutes in 1:3 parts water. All forms can be used to make porridge, combined with ground nuts to make a roast or added to stews. Oatmeal is low in gluten so can't be used to make a loaf, but can be mixed with wheat flour to add flavour and texture to bread, muffins, pancakes etc. Quinoa (gluten free) Quinoa is an ancient crop which fed the Central American Aztec Indians for thousands of years, and which has recently been cultivated in Britain. Unlike most grains, it does not belong to the grass family, but is a relative of the garden weed called Fat Hen. It is very nutritious, containing between 13-14% protein with a good amino acid composition but has no gluten so it cannot be used for bread making. Instead, it is cooked for 15 minutes in 1:3 parts water and served as a side dish or may be used in risotto, pilaf, vegetable stuffing etc. Rice (gluten-free) Rice is one of the world's most important crops. It originated in Asia but is now grown throughout the humid, sub-tropical regions. It differs from most other cereals in requiring land that is submerged in water to grow, though some varieties do grow in upland areas. Rice is a good source of carbohydrate but doesn't have quite as much protein as some other cereals (6.5g per 100g). Unpolished rice (i.e. wholegrain/brown rice) is a good source of B vitamins too. There are three basic kinds in culinary terms: long, medium and short grain. Long used traditionally in savory dishes, short in dessert cooking, although this varies across the globe and it is really a matter of personal preference. Long wholegrain rice needs to cook in 1:2 parts water for 35-40 minutes. Rice flour is available but because of the lack of gluten, it cannot be used to make a yeasted loaf but can be used for cakes, biscuits and pancakes. Rice flakes (brown and white) can be added to muesli or made into a milk pudding or porridge. Wild Rice Wild rice is not rice at all but an American grass used as an important food by the Indians and early settlers. Difficulty in harvesting makes it expensive, but the colour, a purplish black and its subtly nutty flavour make it a good base for a special dish and it can be economically mixed with other rices, but may need pre-cooking as it takes 45-50 minutes to cook in 1:3 parts of water. 4. Answer the following questions: 1. Quinoa is an ancient crop, isn’t it? 2. Why is wild rice expensive? 3. How long should wild rice be cooked? 4. Is whole or pot barley more nutritious? 5.

Put down the Russian for: granary-type loaves yeasted loaf wheat and barley soil fertility grain allergies wheat seem 7. Read the micro text and define the main idea of the text. Rye is the least important cereal crop and is usually only grown where conditions are relatively unfavorable and other cereals don't do well. It probably originated in S W Asia, but the name occurs in Northern European languages, which suggest early cultivation in that area. It is very hardy and so grows in temperate and cool regions and at high altitudes, and is very tolerant of poor soil fertility. It is the only cereal apart from wheat and barley that has enough gluten to make a yeasted loaf, but it has less gluten than wheat, so rye bread is denser. It is more usual to mix rye flour with wheat flour. Rye grains should be cooked in 1:3 parts water for 45-60 minutes. Kibbled rye is often added to granary-type loaves. You can also add rye to stews and rye flakes are available, which can be used in muesli. 100g of rye gives 9.4g protein. 8. Read and translate the text. Spelt Spelt is closely related to common wheat, originating in the Middle East, and has been popular for decades in Eastern Europe. Higher in protein than wheat, it appears to have a different molecular structure, appearing to cause fewer problems than wheat for some sufferers of grain allergies. It has an intense nutty, wheaty flavor. The flour is excellent for bread making and spelt pasta is becoming more widely available. Wheat This is the most familiar cereal used in Britain today; it is used for bread, cakes, biscuits, pastry, breakfast cereals and pasta. All the present varieties of wheat seem to be derived from hybrid wild wheat that grew in the Middle East 10,000 years ago. Over 30,000 varieties are said to be in cultivation. Wheat can be grown in a very wide range of climatic conditions but is most successful in temperate zones including the UK, North America, Southern Russia and South West Australia. Nutritionally, 100g whole wheat provides 14g protein, 2.2g fat, 69.1g carbohydrate, 2.3g fibre, 3.1mg iron, 36mg calcium. Wheat grains, also called wheat berries, can be eaten whole, cooked in 1:3 parts of water for 40-60 minutes; they have a satisfying, chewy texture. Cracked or kibbled wheat is the dried whole grains cut by steel blades. Bulgur wheat, made from the whole grains steamed before cracking, only needs rehydrating by soaking in boiling water or stock. Couscous is the steamed, dried and cracked grains of durum wheat and is more refined than bulgur. Soak in 2 parts of water/stock to rehydrate, traditionally it is steamed after soaking. Strong wheat flour (high gluten content) is required for yeasted breadmaking and puff pastry. Plain flour is used for general cooking including cakes and short crust pastry. Wheat flakes are used for porridge, muesli and flapjacks. Wheat germ is an excellent source of nutrients, especially vitamin E. 9. Arrange the words in the order of appearance in the text.

KINDS OF FOOD. FRUIT PRODUCTS Vocabulary of the text Spoilage Non-heat-resistant Canning Sterilization Sealed container Freezing Syrup Oxidation Dehydration Sun-drying Solution Moisture contents To mold Inedible Pickling Evaporation Pectin To clarify To pasteurize Clarification порча (гниение) нетеплоустойчивые консервирование стерилизация герметичный корпус замораживание сироп окисление обезвоживание (дегидратация) воздушно-солнечная сушка раствор содержание влаги плесневеть несъедобный маринование испарение пектин очищать пастеризовать осветление The term fruit generally refers to fruits and berries. Being acid, fruits lend themselves to conventional methods of preservation and manufacture. Canning. Because the main spoilage agents in fruits are non-heat-resistant microorganisms, canning preservation is functional. Exposure of prepared fruit products to temperatures near 93.3 degrees is generally adequate for their sterilization. The process involves the heating of manufactured fruit products in sealed containers of glass, tin, or plastic, in boiling water, or steam at atmospheric pressure. Freezing. The generally delicate nature of fruits requires rapid freezing techniques for best results, followed by storage of frozen products at -17 degrees or below. Sugar is usually a part of the packing medium, either mixed in dry or added as a syrup. Vitamin C (ascorbic acid) may be added to avoid color changes due to oxidation in ruptured tissues exposed to air. Dehydration. Sun drying is a very widely used method of preserving fruits. Dehydration, or artificial drying of fruits, yields greatly improved products but is more expensive. Successful dehydration involves washing, sorting, trimming, slicing, exposure to burning sulfur fumes, or dipping into sulfite solutions, followed by the removal of the water in the tissues with dry hot air. The sulfur treatment is useful in protecting the delicate nature of fruit flavors and preventing discoloration due to oxidation. Dried fruits with moisture contents of less than 20% will usually keep for several years if protected from the elements and insects. Dried fruits with more than 26% moisture will mold and become inedible if not highly sulfured. Drying may be accomplished by exposing the prepared, sulfured fruit to the sun or to drying in tunnels, in vacuum dryers, or in freeze dryers. Pickling. Fruits may be pickled by boiling in water until tender and placing in a spiced sugar syrup. The fruits are packaged into glass or tinned containers, filled with hot syrup, and sealed. If fruit and syrup are above 82.2 degrees when packaged, no further processing is required. Filled containers should be inverted to sterilize the lids. Jams, jellies and preserves. The manufacture of fruit into jellies and preserves is one of the oldest and most important means of using large amounts of sound fruits which may not be well shaped or which for other reasons are unsuited for fresh market outlets. Jellies are prepared by boiling the fruit, extracting the juice, filtering the juice, adding sugar, concentrating, packaging and sterilizing. The requirements of a fruit jelly are that the proper combination of acid, pectin and sugar in water be reached so that a gel will form. Too high a sugar content results in a sticky gel. Acid, pectin and sugar concentrations are independent; each must be in balance with the other variables to have acceptable gel formation. Jams, jellies, preserves, marmelades and fruit butters are products prepared from fruit juices or fruit with added sugar. After concentration by evaporation to a point where microbial spoilage cannot occur, the prepared products can be safely stored. Commercially, the prepared fruit products are filled into containers, usually glass, allowing the mass to set in the container. Fruits vary in jelly-making ability. Crab apples, sour apple varietes which are not overly mature, sour berries, citrus fruits, grapes, sour cherries, and cranberries contain sufficient pectin and acid to yield good jelly naturally. Sweet cherries and melons are rich in pectin but low in acid. Strawberries and apricots contain sufficient acid but are low in pectin. Commercially available pectin and edible acids permit a manufacturer to correct these deficiences in fruits. Juices. Juices are made from fruit usually lacking good market quality, but of sound character otherwise. Fruits are washed, sorted, pulped and extracted. Some fruit juices are improved in appearance if clarified. This does not apply to juices of citrus, apricot, pineapple and others which are more popular when cloudy. Apple, cranberry, cherry and grape juices are examples of clarified juices which have good acceptance. These fruits may be preserved by canning, freezing, dehydration or chemical additives. Grape fruit is made from mature grapes which are washed, crushed and pressed. The juice is pasteurized by heating to above 79.4, then stored to permit separation of suspended solids at temperatures below 0. The settled juice is separated from the sediment, then filtered, bottled and sterilized. Apple juice is made from washed apples which are crushed and pressed. The juice is filtered and bottled, with or without clarification. EXERCISES 1. Answer the questions: 1) What is dehydration ? 2) What fruits are used in the production of jams and juices? 3) What do citrus fruits, grapes, sour cherries, and cranberries contain? 4) What is grape fruit made from? 5) Why do fruits preserved by canning, freezing lose amount of vitamins? 2.

BEVERAGES Beverages To appreciate Nutritive value Potassium Sodium Therapeutic Vehicle Brewery Riboflavin To acquire Toxic manifestation Potable Distilled spirits Subsequently Molasses Essential oil Cognac Distinct Stone To pronounce Rye whisky Juniper berry Vocabulary of the text напитки оценивать питательная ценность калий натрий лечебный растворитель, связующее звено пивоваренный завод рибофлавин, витамин Б2 приобретать токсичное проявление питьевой очищенные (дистиллированные) спирты впоследствии меласса ( черная патока) эфирное масло коньяк особенный косточка резко выражать хлебная водка можжевельник Although most adults drink one or two litres of water a day, much of this is in the form of coffee, tea, fruit juices, soft drinks, beer, wines or spirits, or other liquids. In general, these are appreciated more for their taste and the substances they contain, or, for their effects, than for their nutritive value. Fruit juices are, of course, useful for vitamin C content and being rich in potassium and low in sodium are valuable in therapeutic diets. Coffee and tea by themselves are of no nutritive value, but may be a vehicle for large intakes of sugar, milk or lemon. The alcohol in beer, wines and spirits can serve as a source of energy. Beer contains two to six percent alcohol, natural wines 10 percent, and most spirits just over 30 percent. Since ethyl alcohol has an energy value of seven kilocalories per gram, very significant amounts of energy can be obtained from alcoholic drinks. With one or two exceptions, they contain no nutrients and are only a source of empty calories. One exception, so-called country beer may be an important source of the B vitamin group. The only vitamin present in significant amounts in beer from a brewery is riboflavin. Wines are devoid of vitamins, but sometimes contain large amounts of iron, probably acquired from iron vessels used in preparation, especially of cheap wine. It is possibly for excess iron to be absorbed and stored in the liver where it may contribute to toxic manifestations. Potable alcoholic beverages are obtained by distilling an alcohol-containing liquid and further treating the distillates to obtain beverages of specific character. The various distilled spirits are classified according to the raw material which has been fermented and subsequently distilled, such as grain, molasses and fruit, and the further treatment given the distillate to add specific flavors and aroma. These are referred to as compounded or flavored spirits. Examples of beverages made from grain are whiskies, vodka and gin. Some types of vodka and gin are made from potatoes. The so-called compounded or flavored spirits are made from distilled spirits by the addition of sugar, essential oils, herbs or other ingredients. Brandies. Brandy is a spirit obtained from the distillation of wine or a fermented fruit juice, usually after aging of the wine in wooden casks. Cognac is a brandy distilled from wines made of grapes grown within the legal limits of Charente Department, the Cognac region of France. American brandies are primarily products of California and have a flavor different from the European brandies. Apple brandy is distilled from completely fermented apple juice and aged in oak barrels for 5-10 years, it has a distinct apple flavor. Other fruits from which brandy is made include black, wild cherries, plums, blackberries and apricots. When stone fruits are used, some of the stones are broken or crushed and a small amount of the oil distilled over with the spirit, giving the brandy a more or less pronounced and distinctive bitter almond flavor. Whiskies are spirits made by distilling fermented grain mashes and aging the distillate in wood, usually oak. Examples are Scotch whisky, Irish whisky, Canadian whisky and rye whisky. In all types of whiskies the type and quality of water used in the plant is an important factor in tha quality of the finished product. Gins consist essentially of a pure grade of alcohol which has been flavored with an extract of the juniper berry as the chief flavoring agent. There are two principal types of gin: English, or London dry gin, and Dutch gin. Rum. The alcoholic distillate from fermented sugar cane juice or molasses is known as rum. Vodka is a product originally produced in Russia but now popular in many countries. It is usually made from wheat. It is highly rectified during distillation and thus is a very pure neutral spirit without a pronounced taste. It is not aged. EXERCISES 1. Answer the questions: 1) What kinds of beverages does a person consume during the day? 2) Why are fruit juices useful? 3) What are alcoholic beverages for people? 4) What vitamins may wine and beer contain? 5) What processes occur during the production of alcoholic beverages? 6) What is brandy? 7) What is the difference between whiskey and rum? 8) Why is Russian vodka considered to be special? 9) What is the consequence of drinking too much alcoholic beverages? 2.

The beer… Frozen foods Frozen foods are products of the food preservation process of freezing. This process has been employed by people in the Arctic from prehistoric times. Eskimos throw fresh-caught fish on the ice to freeze, and naturally frozen fish have been a trade staple of the Great Lakes region of North America since the mid-19th cent. Brine and cold-room convection methods were in use in Europe and the United States from about 1860 for freezing meat, fish, poultry, and eggs. In the early part of the 20th cent. small fruits were frozen for manufacturers of preserves, bakery products, and ice cream. Freezing prevents food spoilage by inhibiting microorganic and enzyme action. Deterioration is rapid after thawing, since reactivated organisms attack cells injured by ice crystals. Earlier methods involved inserting the food into chilled brine or an ice and salt mixture. In flash freezing, commercially begun in Germany in the early 20th cent., rapid chilling gives less time for the diffusion of salts and water for microorganic action. Methods of quick freezing include direct contact with refrigeration, indirect cooling by contact of the product with refrigerated shelves, cold blasts, or a combination of these methods. The frozen food industry has expanded rapidly because of the labor-saving and space-saving advantages of frozen foods and because the freezing process generally involves less loss of taste, flavor, and appearance than do other methods; it has been paralleled by the development of suitable containers and of specialized methods of transportation, storage, and retailing. Organic food Organic food is food raised without chemicals and processed without additives. Under standards synthetic fertilizers and pesticides and antibiotics may not be used in raising organic foods, and the use of irradiation, biotechnology, and sewer-sludge fertilizer is also banned. Food whose ingredients are at least 95% organic by weight may carry the “USDA ORGANIC” label; products containing only organic ingredients are labeled 100% organic. Proponents of organic food claim that it is more nutritious, safer to eat, and usually tastes better because it contains no synthetically compounded fertilizers, pesticides, herbicides, hormones, medicated feed, or antibiotics or chemicals used in food processing; these claims are disputed by conventional-food growers and processors. Organic foods have become steadily more popular as the public has become more concerned about health risks associated with chemicals in food products. Organic produce is now available in many food outlets, including major supermarket chains. Organic food is generally more expensive because organic farming requires more manual labor and attention. Nuts and Seeds Lesson 1 1. Read the words: conveniently vegetarian flavouring rancidity phosphorous 2. Master the active vocabulary. Cover the left column and translate the Russian words back into English. Nut орех seeds семечко, семя shell оболочка, корка potassium калий excess чрезмерность, неумеренность 3. Word formation. Analyze the meaning of the suffixes: -ly, -less, -able. Find words formed with these suffixes in the text and translate them. Give your own examples. Nuts are seeds that are covered with a hard shell. Most are the seeds of trees, but the seeds of a few other plants that are not strictly nuts will also be considered here as they can be conveniently classified with nuts for culinary purposes. Nuts can be used in many ways. Whole, flaked and ground nuts and nut butters are widely available. A classic vegetarian savoury is nut roast and many vegetarian cook books give a recipe for one, which can be endlessly varied with different herbs and flavourings and different combinations of nuts and cereals. Nuts can be added to sweet dishes, cakes and biscuits, and nut butters can be added to soups and stews to thicken them. Nuts in general are very nutritious, providing protein and many essential vitamins, such as A and E, minerals, such as phosphorous and potassium, and fibre. Nuts are also high in carbohydrate and oils, so shouldn't be eaten in excess. Whereas pulses all belong to the legume group of plants, nuts come from a variety of different plant groups, so the nutritional content is more varied too. A brief description of individual varieties is given below, together with the main nutrients they contain. Nuts should be stored in cool, dry conditions in airtight containers away from the light. Because of their high fat content, many of them benefit from storage in the fridge or freezer to deter rancidity. 4. Put down the nouns. Translate the words. Find a word different from others.

The nuts grow inside a hard, woody fruit rather like a coconut shell which has to be broken open to expose the 12-24 nuts inside. Brazils are high in fat, which causes them to go rancid very quickly, and protein. 100g of brazils contain 12g protein, 61g fat, 2.8mg iron, 180mg calcium, 4.2mg zinc. 8. Define the main idea of the text. Cashews are native to America but now grown extensively in India and East Africa. It will withstand rather drier conditions than most other nuts. The nut grows in a curious way on the tree, hanging below a fleshy, apple-like fruit. It is related to the mango, pistachio and poison ivy. High in protein and carbohydrate, 100g cashews contain 17.2g protein, 60 micrograms vitamin A, 3.8mg iron. 9. Read the text. Write out the description of chestnuts. Chestnuts The sweet chestnut is a native of South Europe but is planted elsewhere extensively for both nuts and timber. The nuts can be used in soups, fritters, porridges, stuffings and stews, as well as being roasted or boiled whole. Available fresh (in autumn), dried, canned - whole or pureed, or ground into flour. Dried chestnuts need soaking for at least 1-2 hours and boiling for 45-60 minutes, fresh need boiling for 40 minutes before being peeled. Preserved in syrup they become the famous delicacy, Marron-glace. High in starch, but low in protein and fat, 100g chestnuts contain 36.6g carbohydrate, only 2g protein (the lowest of all nuts) and 2.7g fat. Lesson 3 1.

Unripe nuts contain coconut milk. The nutmeat can be eaten fresh or dried (desiccated or flaked coconut) and is also available in blocks of creamed coconut. Valuable oil is also extracted from the nut meat and used for cooking (although it is very high in saturated fat), margarines, soaps and detergents. 100g fresh coconut contains 3.2g protein and 36g fat, desiccated contains 5.6g protein and 62g fat. 6. Read the micro text and define the main idea of the text. Peanuts are also known as groundnuts or monkey nuts, peanuts are actually legumes. Of South American origin, it's now an important crop all over the tropics and southern USA. It gets its name groundnut because as the pods ripen, they are actually forced underground. Peanuts are high in protein and contain 40-50% oil. The oil is used in cooking, as salad oil, in margarines and the residue is fed to animals. Whole peanuts can be eaten raw or roasted or made into peanut butter (look out for brands which do not contain hydrogenated oils, which are highly saturated).

Soya The soya bean is the seed of the leguminous soya bean plant. Soya foods have been a staple part of the Chinese diet for over 4000 years but have only been widely consumed in Western countries since the 1960's. Soya foods include tofu, tempeh, textured vegetable protein (chunks, mince etc), miso, soya sauces, soya oil and margarine, and soya dairy alternatives. Soya is an excellent source of high quality protein, is low in saturated fats and is cholesterol free. Recent research has indicated soya has several beneficial effects on health in addition to its nutritional benefits. Soya beans contain high concentrations of several compounds which have demonstrated anti-carcinogenic activity. These include isoflavonoids, protease inhibitors and phytic acid. The low incidence of breast and colon cancer in China and Japan has been partially attributed to the high consumption of soya products. The low incidence of menopausal symptoms in Japanese women has also been attributed to high consumption of soya. Soya diets have also been shown to reduce levels of serum cholesterol. 9.

Read and translate the text. Textured Vegetable Protein Textured vegetable protein is basically defatted soya flour which has been processed and dried to give a substance with a sponge-like texture which may be flavoured to resemble meat. Soya beans are dehulled and their oil extracted before being ground into flour. This flour is then mixed with water to remove soluble carbohydrate and the residue is textured by either spinning or extrusion. Extrusion involves passing heated soya residue from a high pressure area to a reduced pressure area through a nozzle resulting in the soya protein expanding. The soya protein is then dehydrated and may be either cut into small chunks or ground into granules. Textured vegetable protein may be purchased either unflavoured or flavoured to resemble meat. It is prepared simply by mixing with water or stock and leaving to stand for a few minutes, after which it may be incorporated into recipes as a meat substitute. Soya protein is also available incorporated into various vegetarian burgers, sausages, canned foods etc. As well as being a good source of fibre and high quality protein. Textured vegetable protein is fortified with vitamin-B12. Tofu Tofu is soya bean curd made from coagulated soya milk. Soya beans are soaked, crushed and heated to produce soya milk to which a coagulating agent such as calcium sulphate or calcium chloride is added. The resulting soya curd is then pressed to give tofu. Tofu is sometimes known as soya cheese, and is sold as blocks packaged in water. It can be bought as silken tofu, which is soft and creamy in texture, or as a denser, firmer version. The firmer kind may also be purchased smoked or marinated. Tofu tends be fairly bland tasting and is best used in recipes where flavour is imparted by other ingredients. Firm tofu may be marinated, fried, stir-fried, deep-fried, sauteed, diced and added to salads or casseroles. Silken tofu can be used for dips, spreads, sauces and sweet dishes. As well as having high protein content, tofu also contains calcium, iron, and vitamins B1, B2 and B3. 7. Make sentences of the following words. 1.

Tempeh Tempeh is a fermented soya bean paste made by inoculating cooked soya beans with the mould Rhizopus oligosporous. This mould forms a mycelium holding the soya beans together and is responsible for the black specks in tempeh. Tempeh has a chewy texture and distinctive flavour and can be used as a meat substitute in recipes. It may be deep-fried, shallow-fried, baked or steamed. Miso Miso is a fermented condiment made from soya beans, grain (rice or barley), salt and water. Miso production involves steaming polished rice which is then inoculated with the fungus Aspergillus oryzae and left to ferment to give an end product called koji. Koji is then mixed with soya beans which have been heated and extruded to form strands, together with salt and water. This is then left to ferment in large vats. Miso varies widely in flavour, colour, texture and aroma. It is used to give flavour to soups, stews, casseroles, and sauces. 6. Fill in the proper prepositions.

It is most commonly made by soaking soya beans in water which are then strained to remove the fibre. It can also be made from soya protein isolate or soya flour. Compared to full fat cow's milk, soya milk has a lower fat content, a lower proportion of saturated fat, and no cholesterol. It is low in carbohydrate and provides a good source of protein. Some brands may be fortified with calcium, vitamin-D2, vitamin-B12 and vitamin-B2. Soya milk provides an alternative to cow's milk for people with cow's milk protein and lactose intolerance. Cow's milk allergy is most common in infants, and specially formulated soya milks are available for babies. Other soya milks are not suitable as sole foods for young infants. Previously, the media has linked soya milk with having a high aluminium content. However, the aluminium content of soya milks is generally lower than cow's milk, and falls well within acceptable limits dictated by the World Health Organisation. Aluminium in soya milks can be regarded as negligible. Certain infant formulas (both cow's milk and soya milk based) produced from concentrates have been reported as having high levels of aluminium and their suitability for infants has been questioned. A number of different brands of soya milk may be purchased. These may be sweetened or unsweetened and vary in flavour. Market leaders are Provamel, Granose and Plamil. Some supermarkets also sell own-brand soya milk. In addition to soya milk, a range of flavoured soya desert and soya yoghurt products are available. 7. Finish the following sentences. 1.

The fungus is grown in a large fermentation tower to which oxygen, nitrogen, glucose, minerals, and vitamins are continually added. After harvesting, the fungus is heat treated to reduce its RNA content to World Health Organisation recommended levels before being filtered and drained. The resulting sheet of fungal mycelia is mixed with free range egg albumen which acts a binder. Flavouring and colouring may also be added. The mycoprotein is then textured to resemble meat, before being sliced, diced or shredded. Mycoprotein is a source of protein, fibre, biotin, iron and zinc, and is low in saturated fat. Mycoprotein was developed by Rank Hovis McDougall, and is marketed under the name of Quorn by Marlow Foods Ltd (now owned by Premier Foods). A wide range of Quorn ready meals are available including curries, pies, and casseroles, and it may also be purchased as chunks, mince, sausages, burgers, fillets etc. Since January 2005 the entire Quorn range have been approved by the Vegetarian Society (previously the manufacturers had not been able to source enough free range eggs to use accross whole product range). 7.

Think of eight questions covering the text. Put them to your group-mates. 5. To be translated in written. Pulses Peas, beans and lentils are known as pulses. They are the seeds of plants belonging to the family Leguminosae, which gets its name from the characteristic pod or legume that protects the seeds while they are forming and ripening. With approximately 13,000 species, the family Leguminosae is the second largest in the plant kingdom and it is very important economically. Different kinds of legumes provide us with food, medicines, oils, chemicals, timber, dyes and ornamental garden plants. Legume products include carob, senna, gum arabic, balsam, indigo and licorice. Pulses are valuable because they contain a higher percentage of protein than most other plant foods. Pulses have been used as food for thousands of years. The lentil was probably one of the first plants ever to be domesticated by humans. Most pulses prefer warm climates but there are varieties which grow in temperate regions. They can be eaten fresh or dried and come in a great number of varieties with a range of colours, flavours, and textures. In spite of its common name, the peanut or groundnut is also a legume rather than a nut. All pulses, except for soya beans, are very similar in nutritional content. They are rich in protein, carbohydrate and fibre, and low in fat which is mostly of the unsaturated kind. They are also important sources of some B vitamins. Fresh pulses contain vitamin C, but this declines after harvesting and virtually all is lost from dried pulses. Canned pulses however, retain about half their vitamin C except for canned, processed peas which have been dried before canning. Canning doesn't affect the protein content, eliminates the need for soaking and considerably reduces the cooking time compared with dried pulses. Frozen peas will have also lost about a quarter of their vitamin C content. Pulses are usually eaten for their high protein content. A typical nutritional breakdown is that for haricot beans which are used to make baked beans, contain, per 100g dried beans: 21.4g protein, 1.6g fat, 45.5g carbohydrate, 25.4g fibre, 6.7mg iron and 180mg calcium. The nutritional quality of the soya bean is superior to that of other pulses. It contains more protein and is also a good source of iron and calcium. The nutritional breakdown of soya is per 100g of dried beans: 34.1g protein, 17.7g fat, 28.6g carbohydrate, 8.4mg iron and 226mg calcium. Dried soya beans are lengthy to prepare because they need at least 12 hours soaking and 4 hours cooking time, boiling for the first hour, but nowadays a large number of soya based foods including tofu, tempeh and textured vegetable protein (soya mince or chunks) are available. One advantage of dried pulses is that they will store very well for long periods if kept in a dry, airtight container away from the light. However it is best to eat them as fresh as possible. Pulses toughen on storage and older ones will take longer to cook. Allow about 55g dried weight per person, once soaked and cooked they will at least double in weight. Most dried pulses need soaking for several hours before they can be cooked, exceptions are all lentils, green and yellow split peas, blackeye and mung beans. Soaking times vary from 4-12 hours, it is usually most convenient to soak pulses overnight. Always discard the soaking water, rinse and cook in fresh water without any salt, which toughens the skins and makes for longer cooking. Changing the water will help to reduce the flatulence some people suffer when eating pulses, also reputed to help is the addition of a pinch of aniseeds, caraway, dill or fennel seeds. Consumers should be aware that it is not safe to eat raw or undercooked kidney and soya beans. There is no need to avoid them as long as they are thoroughly cooked. 6. Write out words from the text.

Word formation. Analyze the meaning of the suffixes: -ly, -less, -able. Find words formed with these suffixes in the text and translate them. Give your own examples. Cheese is made by coagulating milk to give curds which are then separated from the liquid, whey, after which they can be processed and matured to produce a wide variety of cheeses. Milk is coagulated by the addition of rennet. The active ingredient of rennet is the enzyme, chymosin (also known as rennin). The usual source of rennet is the stomach of slaughtered newly-born calves. Vegetarian cheeses are manufactured using rennet from either fungal or bacterial sources. Advances in genetic engineering processes means they may now also be made using chymosin produced by genetically altered micro-organisms The exact processes in the making of cheese varies between different varieties. However, all cheeses are made by essentially the same method. Initially, the milk is usually pasteurised by heating at 72°C for 15 seconds to destroy potentially harmful bacteria. The milk is then cooled to around 30°C and a starter culture of lactic acid bacteria is added to help souring. These convert lactose into lactic acid and help in the coagulation process. In addition, they also have a beneficial effect on the eventual quality, taste and consistency of the cheese. Some cheeses are coagulated entirely by lactic acid bacteria and are known as lactic-curd or acid-curd cheeses. However, some cheeses sold as lactic-curd cheese may have had rennet added. The next stage is the addition of rennet, containing the enzyme chymosin. Rennet is usually sourced from the abomasum (fourth stomach) of newly-born calves. Here, chymosin aids the digestion and absorption of milk. Adult cows do not have this enzyme. Chymosin is extracted by washing and drying the stomach lining, which is then cut into small pieces and macerated in a solution of boric acid or brine at 30°C for 4-5 days. Pepsin may sometimes be used instead of chymosin. This is usually derived from the abomasum of grown calves or heifers, or less commonly pigs. Pepsin may be mixed with calf rennin. Rennet coagulates the milk, separating it into curds and whey. This is called curdling. Chymosin breaks down the milk protein casein to paracasein which combines with calcium to form calcium paracaseinate, which separates out. Milk fat and some water also becomes incorporated into this mass, forming curds. The remaining liquid is the whey. The strength of different rennets can vary, though usual strength varies between 1:10,000 and 1:15,000 i.e. one part rennin can coagulate 10-15,000 parts milk. Other substances may also be added during the cheese making process. Calcium chloride is added to improve the curdling process, and potassium nitrate is added to inhibit contaminating bacteria. Dyes (e.g. annatto, beta-carotene), Penicillium roquefortii mould spores to promote blue veining, or propionic acid bacteria to encourage hole formation may be added. Following curdling, the curds are cut and drained. The size of the cut and the methods used vary for different cheese varieties. For soft cheeses, the curds are sparingly cut and allowed to drain naturally. For hard cheeses, the curds are heated and more whey is drained off. The curds are then cut into small pieces, placed in vats and pressed. After pressing, the curds may be treated in a number of ways. They may be moulded into different shapes, soaked in a saltwater solution, be sprayed with mould forming spores or bacteria, washed in alcohol, or covered in herbs. The final stage is ripening, or maturation. This can vary in length from 4 weeks to 2-3 years, depending on the type of cheese. During ripening flavours develop, the cheese becomes firmer and drier, and special characteristics such as holes, blue veining and crust formation occurs. 4. Put down the nouns. Translate the words.

In the past, fig leaves, melon, wild thistle and safflower have all supplied plant rennets for cheese making. However, most widely available vegetarian cheeses are made using rennet produced by fermentation of the fungus Mucor miehei. Vegetarian cheese may also be made using rennet from the bacteria Bacillus subtilis or Bacillus prodigiosum. 5. Which of the following words are nouns? verbs? adjectives? adverbs? Why? genetic material introduce further need calf cells alternatively chymosin can bio-synthesized laboratory 6. Read and translate the text in written. Vegetarian Cheeses Advances in genetic engineering techniques mean that some vegetarian cheeses may now be made using chymosin produced by genetically engineered micro-organisms. The genetic material (DNA) which encodes for chymosin is introduced into a micro-organism which can then be cultured to produce commercial quantities of chymosin. This is done by extracting genetic material from calf stomach cells which acts as a template for producing the chymosin encoding DNA. This can then be introduced into the micro-organism. Once the genetic material is introduced there is no further need for calf cells. Alternatively, the chymosin encoding DNA can be bio-synthesized in the laboratory without the use of calf cells. The chymosin produced is identical to that produced by calf stomach cells. The development of genetically engineered chymosin has been encouraged by shortages and fluctuations in cost of rennet from calves. Its manufacturers claim that genetically engineered chymosin will end the cheese making industry's reliance on the slaughter of calves. Chymosin encoding DNA has been introduced into three different micro-organisms. These are the yeast Kluyveromyces lactis, the fungus Aspergillus niger var awamori, and a strain of the bacteria Escherichia coli. All of these have now been approved and cleared for use by the Ministry of Agriculture, Fisheries & Food. There is no legal requirement for manufacturers to state whether genetically engineered rennet has been used in the cheese making process. Vegetarian cheeses are widely available in supermarkets and health food stores. A wide variety of cheeses are now made with non-animal rennet and labeled as suitable for vegetarians. No particular type of cheese is exclusively vegetarian. Soft cheeses are as likely to be non-vegetarian as hard cheese. 7. Answer the following questions: 1. How can some vegetarian cheeses be made? 2. What may be made using chymosin produced by genetically engineered microorganisms? 3. What encouraged the development of genetically engineered chymosin? 4. Where can one get Vegetarian cheeses? 5. How do Vegetarian cheeses look like? 8. Define the main idea of the text. Cheese is a good source of protein, calcium, zinc, and vitamin B12. However, full fat cheese is a major source of saturated fat which can lead to raised serum cholesterol levels. Also, it contains no carbohydrate or fibre, and is a very poor source of iron. Vegetarians, particularly new vegetarians, should be wary of too high a consumption of cheese. 9. Read the text.

Read the words and put down their Russian equivalents: Camembert __________________________________________ Wensleydale _________________________________________ Cheddar _____________________________________________ Parmesan ____________________________________________ 4. Read the text and define the main idea of the text. The type of cheese produced depends on the milk used and the cheese making process. The milk used may be full fat, semi-skimmed or fully skimmed, this affecting the fat content of the cheese. It may be pasteurised or unpasteurised. Milk from different animals and different breeds is important in determining the final flavour. As well as cow's milk, cheese may be made from sheep or goat's milk. Soft cheeses may be fresh or ripened. Fresh cheeses include quark, cottage cheese and cream cheese. Ripened soft cheeses include Brie and Camembert. Semi-soft cheeses include Stilton, Wensleydale and Gorgonzola. Hard cheeses include Cheddar, Cheshire, and Gruyere. Parmesan is a strongly pressed, very hard, dry cheese ripened for 2-3 years and then grated. Whey cheeses such as Ricotta are made as a by-product of other cheeses from the whey removed during pressing. Processed cheeses are either made with trimmings that are left over from the manufacture of other cheeses, or from dried milk powder. Flavourings, colourings and other additives are used. 5.

These restaurants often have trained chefs who prepare the food, while trained waitstaff serve the customers. The term restaurant is credited to the French from the 19th century, as it relates to the restorative nature of the bullions that were once served in them. However, the concept predates the naming of these establishments, as evidence suggests commercial food preparation may have existed during the age of the city of Pompeii, as well as urban sales of prepared foods in China during the Son Dynasty. The coffee shops or cafes of 17th century Europe may also be considered an early version of the restaurant. In 2005 the United States spent $496 billion annually for out-of-home dining. Expenditures by type of out-of-home dining was as follows, 40% in full-service restaurants, 37.2% in limited service restaurants (fast food), 4.7% in hotels and motels, 6.6% in schools or colleges, 5.4% in bars and vending machines, 4.0% in recreational places, and 2.2% in other which includes military bases. Discuss the following questions: What does the term restaurant relate to? Is it profitable to produce food for sale in restaurants nowdays? What may be considered an early version of the restaurants? Why is a system of “out-of-home dining” so popular in the USA? What type of out-of-home dining is the most popular in the USA? Why does the government of the USA support the system of “out-of-home dining”? What do you think about fast food? Do you often visit restaurants? Why? Food manufacture Vocabulary of the text Pickling – соление,маринование Curing – консервирование, заготовка Curdling – свертывание, застывание Milling – измельчение, дробление Labeling – наклеивание этикетки Butcher – мясник Packaged foods are manufactured outside the home for purchase. This can be as simple as a butcher preparing meat, or as complex as a modern international food industry. Early food processing techniques were limited by available food preservation, packaging and transportation. This mainly involved salting, curing, curdling, drying, pickling, fermentation and smoking. During the industrialization era in the 19th century, food manufacturing arose. This development took advantage of new mass markets and emerging new technology, such as milling, preservation, packaging and labeling and transportation. It brought the advantages of pre-prepared time saving food to the bulk of ordinary people who did not employ domestic servants. At the start of the 21st century, a two-tier structure has arisen, with a few international food processing giants controlling a wide range of well-known food brands. There also exists a wide array of small local or national food processing companies. Advanced technologies have also come to change food manufacture. Computer-based control systems, sophisticated processing and packaging methods, and logistics and distribution advances, can enhance product quality, improve food safety, and reduce costs.

Food is now traded and marketed on a global basis. The variety and availability of food is no longer restricted by the diversity of locally grown food or the limitations of the local growing season. Between 1961 and 1999 there has been a 400% increase in worldwide food exports. Some countries are now economically dependent on food exports, which in some cases account for over 80% of all exports. In 1994 over 100 countries became signatories to the Uruguay Round of the General Agreement on Tariffs and Trade in a dramatic increase in trade liberalization. This included an agreement to reduce subsidies paid to farmers, underpinned by the WTO enforcement of agricultural subsidy, tariffs, import quotas and settlement of trade disputes that cannot be bilaterally resolved. Where trade barriers are raised on the disputed grounds of public health and safety, the WTO refer the dispute to the Codex Alimentarius Commission, which was founded in 1962 by the United Nations Food and Agriculture Organization and the World Health Organization. Trade liberalization has greatly affected world food trade.

Texts for reading 1. Read the text. Translate it using a dictionary. Red kidney beans: Incidents of food poisoning have been reported associated with the consumption of raw or undercooked red kidney beans. Symptoms may develop after eating only four raw beans and include nausea, vomiting and abdominal pain followed by diarrhoea. A naturally occurring haemaglutin is responsible for the illness, but can be destroyed by high temperature cooking, making the beans completely safe to eat. For this reason, kidney beans must not be sprouted. Kidney beans should be soaked for at least 8 hours in enough cold water to keep them covered. After soaking, drain and rinse the beans, discarding the soaking water. Put them into a pan with cold water to cover and bring to the boil. The beans must now boil for 10 minutes to destroy the toxin. After this the beans should be simmered until cooked (approximately 45-60 minutes) and they should have an even creamy texture throughout - if the centre is still hard and white, they require longer cooking. Soya beans: Contain an anti-trypsin factor (or trypsin inhibitor) which prevents the assimilation of the amino acid methionine. Soya beans also require careful cooking to ensure destruction of this factor. They should be soaked for at least 12 hours, drained and rinsed then covered with fresh water and brought to the boil. Soya beans should be boiled for the first hour of cooking. They can then be simmered for the remaining 2-3 hours that it takes to cook them. Soya flour should state heat treated on its packaging. Other soya products (e.g. tofu, tempeh, soya milk, soya sauces and miso) are quite safe to use. Soya beans can be sprouted, but the sprouts should be quickly blanched in boiling water to inactivate the trypsin inhibitor. Pressure cooking: The temperatures achieved in pressure cooking are adequate to destroy both haemaglutins and the trypsin inhibitor. Pressure cooking also considerably reduces cooking times - kidney beans 10-20 minutes, soya beans 1 hour. Canning: The temperature achieved in the canning process also renders pulses quite safe. Slow cookers: Pulses must be soaked and boiled for 10 minutes before being added to a slow cooker, as they do not reach sufficiently high temperatures to destroy the toxins. As beans and peas are all very similar nutritionally, with the exception of soya, they can be interchanged in most recipes if you want to experiment or have run out of one kind, as long as you take into account the different cooking times. If the beans are likely to need a lot longer to cook than the other ingredients, try pre-cooking them in a separate pan before adding to the other ingredients or using canned beans. 2. Read the text “Alcohol”. Say what recipes you know. The use of animal derived products in the production of alcoholic beverages is fairly widespread not because no alternatives exist, but because they always have been used and there is little demand from the consumer for an alternative. The main obstacle when trying to judge the acceptability to vegetarians of any given product is a clause in the 1984 Food Labelling Regulations (UK) which exclude from the 1984 Food Act all drinks with an alcohol content exceeding 1.2% by volume (ABV), leaving only very low or non-alcoholic beers, wines and ciders being required to list all ingredients. The main appearance of animal derived products is in the fining or clearing process, though others may be used as colorants or anti-foaming agents. It must be pointed out that alcohol is routinely tested on thousands of animals each year (though this is not usually done directly by any individual company). Beer Cask-conditioned ales need fining to clear the material (especially the yeast) held in suspension in the liquid. This is invariably done by adding isinglass, derived from the swim bladders of certain tropical fish especially the Chinese sturgeon, which acts as a falling suspension. If you were to hold a pint of real ale up to the light and see cloudy lumps swirling around that would suggest that the cask had been recently disturbed and the isinglass shaken up from the bottom. Bottled naturally conditioned beers will not always have been treated with isinglass. Keg Beers and Lagers are pasteurised and usually passed through Chill Filters, as are canned beers and some bottled beers, however a considerable number of breweries still use isinglass to clear their pasturised beers, though sometimes only to rescue selected batches which are considered too hazey. Also occasionally the sometimes animal derived additive Glyceryl Monostearate is used in place of 900 Dimethylpolysiloxane as a foam-control agent in the production of keg beers. It is sometimes possible to buy barrels of cask-conditioned beer from a brewery before it has been fined. The beer would then have to be left for a considerable time to stand before consumption. To our knowledge, only one pub in England sells unfined real ale on draught: The Cumberland Arms in Byker, Newcastle on Tyne. Cider Most of the main brands of cider will have been fined using gelatine. Scrumpy type ciders are less likely to have been fined. Wine With wine, it is again in the fining process that animal derived ingredients make an appearance. Finings can be isinglass, gelatin, egg albumen, modified casein (from milk), chitin (derived from the shells of crabs or lobsters) or ox blood (rarely used today). But alternatives do exist in the form of bentonite, kieselguhr, kaolin and silica gel or solution. Also newer methods such as centrefuging and filtering are becoming more popular. The majority of organic wines do not use animal derived finings - but some do, Thorson's Organic Wine Guide by Jerry Lockspeiser and Jackie Gear, lists those wines which are suitable. You might like to note that the Wine Development Board claim that the fining agents are removed at the end of the process with the possible exception of very minute quantities. Spirits Most spirits appear to be acceptable to vegetarians, with the possible exception of Malt Whisky, some blended whiskies and Spanish Brandies which have been conditioned in casks which had previously held sherry which may have been treated with animal derived finings. (Brandy itself is not produced from wine which has undergone any fining processes). Also some imported Vodkas may have been passed through a bone charcoal filter. Fortified Wines All ports except crusted port are fined using gelatin. Sherry should be treated in a similar way to wine. Colorants E120 cochineal produced by extracting the red body material from pregnant scale insects of the species Dactilopius Coccus is used as a colorant in a small number of red wines, soft drinks and Campari. 3.

For the largest part fruit consists of water just like the human body does Like 80% of our body is water so does 80% of fruit consist of water! If you think about it, it's logical for the human body to consume food that contains as much water as the body itself. The nutrition that meets that requirement is fruit. There is no other food than fruit on this planet that contains on average 80% water. Vegetables also contain a lot of water and are therefore second best. Fruit is 100% bad-cholesterol free . No doubt about this argument. Too much bad-cholesterol is not good for our bodies and fruit doesn't contain bad-cholesterol. Animal products like meat and dairy contain a lot of badcholesterol. Fruit stimulates the memory. If you didn’t know yet: fruit is the ultimate brain fuel. Fruit has a positive effect on our brains. The way this works still has to be found out and many scientists are looking into it as we speak. What we do know is that if you consume fruit effectively, your brains can recall information faster and more easily. This is very useful information for people who are preparing for an exam. The idea that fruit is an expensive nutrition. Did you always think that fruit was an expensive product? Take a good look at how much money you spend on other food. It could be worth something to replace some of those expenses with fruit. We think that fruit is the healthiest food on earth and therefore it is well worth spending our money on. The miraculous healing effects of fruit. Spectacular stories about people that cured from uncurable diseases by a strict diet of raw fruits and/or vegetables are well known but do we want to believe them? We still don't know that much about fruit and its contents. Fibers We do know now that a diet with plenty of fibers helps against corpulence, high blood pressure, and other factors that increase the chance for a heart disease. The consumed amounts of fibers maybe even a more important factor than the amount of fat that is consumed by people! The food that contains these healthy (natural) fibers is.... right: fruit! (Vegetables as well). The American Heart Association advises to consume 25 to 30 grams of fibers out of fresh fruits and/or vegetables. In practice this means: have five to nine portions of fresh fruits or vegetables a day. 4. To be translated in writing. Fruit makes you feel better Several stories have told us about people that were frequently depressed and how they got out of their depression slowly but surely after consuming substantial amounts of fresh fruit on a regular basis. Eating much fruit can have a mysterious healing effect on human beings. Even better is to drink a lot of freshly squeezed fruit drinks on a regular basis. It will take approximately 30 days until you start to notice the effects. Don't forget to drink these smoothies 20 minutes before the consumption of other meals. This way the fruit will not ferment in the stomach and the nutritious elements can be absorbed by the blood effectively. Ethical reasons to eat fruit Fruit doesn't have to be killed and slaughtered before you can eat it. The fruits are just hanging there waiting to be picked by you! This ethical argument (often used by vegetarians and vegans to not eat meat) claims that fruit is a non-animal food. Many people see animals, especially mammals, as living creatures just like humans. There are religions that say that animals have souls like us. The native Americans first asked the animal's spirit if they could kill it before they did so. Fruit has never been said to have a soul and thus can be eaten without causing any harm. Ethical or religious arguments aside, we think it's a shame that we as human beings don't eat much fruit when there is such an abundant assortment of fruits and vegetables available. 5. Find more proverbs proving the text. Fruit is the most natural food When you see a piece of fruit hanging from a tree that tree is telling you something: "Eat my fruits and help me spread my seeds." That’s how nature works. Humans eat vegetables and fruits and consequently help the plants to spread. Humans use animals to work the land to grow the plants and trees that produce these fruits and vegetables. In more and more people's opinion this is the way it was all meant to be. 6. Say if you follow the rules. A human diet A healthy diet should consist for a great deal of freshly squeezed fruit juices, raw fruits and vegetables. Some tips: A good start is to eat and drink more fresh fruits; it’s as simple as that. Before you know it you will feel much better; Don't forget to eat fruit on an empty stomach, not after other meals and; inform yourself about the substances that our 'modern' food contains. Fruit juices, go squeeze! Fruit juices taste the best. 7. Read the text. Make ten questions to the text. Fruit and the memory Fruit has a very positive effect on the brains just like carrots. So if you want to stimulate your brain functions you have to eat much fresh fruit and carrots (raw). One of the substances that fruit contains are natural sugars. They stimulate the brain so we can think faster and recall information more quickly. There are many other substances that fruit contains which scientists think they stimulate the brain. How this works and which substance is responsible for which effect is still unknown as of yet and research is done at this very moment. We would like to tell you more about how students can improve their results by changing their eating habits before they have an exam. Fruit is the ultimate brain fuel! You can actually improve your test results simply by changing your eating habits between waking up and doing the exam. The big trick is to consume fruit effectively. Have only fruit but as much as you want before you do your test and avoid the brain blocking foods white flour, refined white sugar, meat and dairy. Check it out yourself once and you'll notice that you can think much more clear and faster if you have only eaten the right and light stuff before the exam. Afterwards you can have whatever you want! The effect fruit has on your brain is that it makes you think faster and recall information more easily. This is only an example. There is much more to learn about nutrition. There is also nutrition that has a negative effect on your brains. Here is a list of things that have a negative effect on the functioning of the brains: White flour, especially in combination with cheese. This forms a sticky substance in the intestines that costs much energy to digest. Much blood has to be sent to the digestive system so it cannot be sent to your head; Refined white sugar; Turkey; it contains a toxic element that has a strong tiring effect, it makes you sleepy; The combination of proteins (meat) and starch (potatoes). These two foods are burnt in a different way. It will cost your body more energy to burn them together than apart from each other. 8. Read the text. Find answers to the questions. 1. There is plenty of evidence that people who eat a lot of fruits and vegetables stay healthier, isn’t there? 2. Who recommend an intake of six portions of fruits or vegetables each day? 3. What are the main compounds of fruit? Fruits and vegetables are good for us - what is the evidence? It is widely accepted that fruits and vegetables are good for us and many national governments run promotions aimed at encouraging increased consumption. There is plenty of evidence that people who eat a lot of fruits and vegetables stay healthier than those who do not. It is also difficult to link particular compounds to specific protective effects in humans but this is an area of intense study and relevant papers appear in the scientific literature all the time. Cardiovascular disease (CVD) remains a major cause of premature death in all western countries. In 1994 the UK Department of Health published a comprehensive review of the evidence linking eating habits to the risk of CVD and stroke. 414 references are cited. The report concludes that there is sufficient evidence about the protective effects of fruits and vegetables to recommend an intake of six portions of fruits or vegetables each day. This advice is linked to recommendations to eat two portions of pasta, rice or potatoes plus four slices of bread each day and to reduce fat intake. Ness and Powles carried out a systematic review of reports on the protective effects of fruits and vegetables as regards CVD, stroke and general circulatory diseases. They conclude that the evidence supports claims that eating fruits and vegetables lowers the risk of these diseases. Fruits and vegetables provide a range of antioxidants which have been shown to help to reduce the risk of CVD and stroke and they give us potassium which is needed for healthy heart function. In a far reaching review of the evidence for the relationship between what we eat and the risk of developing cancer, a recent UK Department of Health publication looked at all food groups and a range of cancers. A scoring system was developed to help judge the scientific quality of information from relevant studies. 937 references are quoted. Hopefully, the conclusions of the report and the advice given are the most reliable currently available. Overall, the evidence is consistent that a high level of consumption of fruits and vegetables reduces cancer risk. Looking more carefully at specific cancers, the report concludes that for cancer of the bladder, breast, cervix, larynx, oesophagus, pancreas, prostate and stomach(gastric) there is strong evidence for the combined protective effects of higher consumption or both fruits and vegetables. With cancer of the colon and rectum, the report states that there is evidence that higher intake of vegetables lowers the risk of colo-rectal cancer. For cancer of the mouth and pharynx, the report states that there is some evidence that a higher level of fruit intake protects against these cancers but that there is no consistent evidence about vegetables. At the Food & Cancer Prevention III Symposium held in Norwich, UK in September 1999, the chairman of the European Cancer Prevention Organisation, Dr Michael Hill, made the following statements. He said there is such strong evidence that adequate consumption of fruits and vegetables gives protection against the risk of developing cancer that it cannot be ignored. The observations must be regarded as proven because the data are so strong and unanimous. In addition, there is no evidence at all that eating fruits and vegetables does any harm - except in gross excess. Many of the compounds from fruits and vegetables have more than one role in helping to keep us healthy and are involved both with immediate good health and with protection against longer-term illnesses. Synergy has a role to play, many compounds require co-factors and will only be effective when all the necessary components are present. Vitamin C is a good example of a compound, present in fruits and vegetables, which is essential for immediate good health. Its role is well-defined, a lot is known about how it fulfils that particular role in the human body and there is information on recommended daily intakes. Scurvy was the scourge of sailors in the days of long ocean voyages. In the early stages of the disease sufferers experienced swelling and bleeding of the gums and bleeding of the skin. Complications and death frequently followed. In 1754, a Scottish naval doctor showed that scurvy can be treated and prevented by the use of orange or lemon juice. It was not until 1932 that vitamin C, chemical name ascorbic acid, was identified as the curative agent for scurvy. It is possible to show the causal relationship between vitamin C deficiency and scurvy and to monitor recovery when consumption of the vitamin is increased. Vitamin C is also a good example of a compound which has more than one function. It is involved in collagen synthesis, enhances iron absorption and is a potent anti-oxidant which protects our cells from oxidative damage. Not so dramatic as the life-threatening deficiency illnesses but very much a health issue is the more common situation where there is less-than-optimum intake of vitamins and minerals. We need sufficiently high intake of the important vitamins and minerals which are involved in metabolic and other body functions to remain fit and well and enjoy a good quality of life. Ideally, we should get enough of these by eating a mixed, balanced diet rich in fruits and vegetables. An exception is the B vitamin, folate. Women who intend to become pregnant are advised to take folate supplements as well as eating lots of green vegetables and fruits. A balanced diet is important for health and fitness. Make a list of the foods you eat regularly. Compare your list with other students. 1) Who has the healthiest diet? 2) What advice would you give to the others? Examples: if I were you, I would cut out…They’re very high in salt, and too much salt is bad for you. You should really eat more green vegetables. You;re not getting enough vitamins. 9. Read the text. Define what vitamins correspond to the parts of the text. Vitamin A Vitamin E Vitamin K Vitamin B Vitamin C Vitamins, carotenoids and minerals from fruits and vegetables. Vitamins are essential dietary substances which the human body cannot synthesize. They are needed in small amounts for metabolic processes and they may be either water-soluble or fatsoluble. Vitamin deficiency can have profound ill effects on body metabolism and general health. The fat soluble vitamins, A, D (not found in fruits and vegetables) and vitamins E and K are stored by the body so we do not necessarily have to eat all of them everyday. Fruits and vegetables are primary sources of provitamin A carotenoids. Red, orange and yellow fruits and vegetables get their bright colours from chemicals known as carotenoids. The carotenoids, a-carotene, b-carotene and b-cryptoxanthin have provitamin A activity and are converted into vitamin A in the human body. The non-provitamin A carotenoids, lycopene, lutein and and zeaxanthin are also important for health. It is essential for growth and normal function of the retina of the eye and deficiency results in eye malfunction, night blindness and xerophthalmia (a lesion of the conjunctiva and cornea). More recently, lutein (found in yellow/green vegetables) has been found to be concentrated in the eye and may perform an important protective role. Vitamin A has a role in the maintenance of normal epithelial tissue, the maintenance of bone growth and overall growth and reproduction. Irrespective of their provitamin A role, carotenoids have diverse biological functions, not all of which are present in each carotenoid. It is thought that the most effective overall protection comes from eating a mix of these compounds in the form of carotenoid-rich fruits and vegetables. Carrots and pumpkins are sources of a-carotene and carrots, spinach, peaches and apricots are sources of b-carotene. The most common source of lycopene is tomatoes. Lutein and zeaxanthin are found in broccoli, spinach and other green vegetables and in peas, red peppers and celery. Cyptoxanthin occurs in oranges and some other fruits. Eight tocopherols and tocotrienols with vitamin E activity are known, the tocopherols are the more potent. a-tocopherol is the most active form with b- and c-tocopherol and b-tocotrienol being less so. Vitamin E acts as an antioxidant and free radical scavenger in the lipid membranes of human cells and tissues. Vitamin E also has a function in the formation of red blood cells, muscle and other tissue and is needed for general good health. It is found primarily in vegetable oils, seed oils, cereals and avocado pears. It occurs as vitamin K1 (phylloquinone) and as vitamin K2 (menaquinone). It is necessary for normal blood clotting and deficiency leads to increased clotting time. Vitamin K1 is found in fresh green vegetables and in liver. Small amounts occur in cereals and fruit. Vitamin K2 is also produced by the intestinal bacteria. The water-soluble vitamins are not stored in the body and must be eaten regularly to maintain good health. It comprises vitamin B1(thiamine), vitamin B2 (riboflavin), vitamin B6 (pyridoxine), vitamin B12 (not found in fruits and vegetables), folate, vitamin B3 (niacin), panothenic acid and biotin. Folate has attracted a lot of attention in recent years. It is important in the formation of cells, particularly red blood cells and helps to maintain the functions of the intestinal tract and to prevent some forms of anaemia. Maternal deficiency during the first few weeks of pregnancy can lead to the birth of infants with neural tube defects, including spina bifida, in which the spinal cord is not completely formed and anencephaly, in which a major part of the brain never develops. Large-scale studies have proved that most cases of neural tube defects can be prevented by increasing folate for at least one month before conception and during pregnancy. Folate, along with B6 and B12 can lower levels of an amino acid called homocysteine in the blood. Recent work has linked high levels of homocysteine to increased risk of heart attack and stroke. High levels of homocysteine can lead to damage in blood vessels similar to high levels of cholesterol. Folate is found in vegetables, particularly the green, leafy ones and in some fruits, these items are excellent natural sources and should be eaten regularly. Of the other vitamins of the B-complex, thiamine is needed for energy metabolism and nervous system function. Deficiency results in beri-beri, a disease which causes inflammation of nerves all over the body. Amounts in vegetable material are low. Riboflavin is involved in energy metabolism and maintenance of eye tissue. It is found in low amounts in leafy green vegetables. Niacin helps in energy-producing reactions in cells and aids the nervous system. It is partially synthesised in the body and is found in meat, cereals, diary products and vegetables. Pantothenic acid is required for protein, fats and carbohydrate metabolism and for the formation of certain nerve-regulating substances. It occurs in most foods including fruits and vegetables. Pyridoxine plays a role in protein and fatty acid metabolism and is needed for red blood cell production. Low-ish amounts are found in vegetables and fruits, the best ones being legumes and bananas. Biotin is essential for many of the chemical systems in the body and is involved in the formation of fatty acids and energy production from glucose, it occurs in small amounts in fruits and vegetables. It is an important antioxidant, protecting cells from oxidative damage and reducing the risk of cancer and cardiovascular disease. It has a role in the regeneration of the oxidised form of vitamin E and in enhancing the absorption of iron. Vitamin C is needed for healthy gums, teeth and bones and it helps to speed up wound healing. Deficiency leads to scurvy. With a few exceptions, animals can synthesise vitamin C from D-glucose but primates, including humans, cannot and we must get ours from dietary sources. R.S.D.Read gives a reliable account of the chemistry, physiological functions and metabolism of vitamin C. Vitamin C may have a role in the prevention of cataract, probably through its antioxidative mechanism. Recent work suggests that the amount of vitamin C required to prevent scurvy is not sufficient to protect against other chronic diseases. This additional vitamin C should come from foods, supplements are not recommended. Vitamin C occurs in nearly all fruits and vegetables, good sources are citrus fruits, berries, black currants capsicum and green leafy vegetables. Weight for weight, potatoes is not rich in vitamin C but they are a useful source of the vitamin as some EU populations eat them frequently and in fairly large portions. 10. Read the text. Define the main idea of the text. Antioxidants Fruits and vegetables are sources of a range of antioxidants, the so-called ACE vitamins, vitamins A, C and E, carotenoids and phytochemicals such as flavonoids. Antioxidants have been suggested to help reduce the risk of cancer, heart attack and stroke. The development of cancer is usually a relatively slow process which requires a substantial proportion of the lifetime of an individual. The cancers of childhood which often affect growing tissues such as the brain or bones are important exceptions to this rule and these diseases are often associated with the presence of mutations (defective genes) inherited from one or both parents. Inherited mutations are also known to be important in the development of cancers of later life but, generally speaking, tumour cells are found to contain a large number of mutations which have been acquired during life. These so-called somatic mutations may occur because of exposure to environmental chemicals which damage the body's blueprint for life, DNA. Molecules which damage DNA can be generated by the body itself. For example, molecules containing oxygen often briefly acquire a special chemical structure enabling them to interact strongly with DNA. These 'free radicals' are generated during normal respiration. Antioxidant substances scavenge free radicals and protect cells from excessive DNA damage. Antioxidants from fruits and vegetables may also help to protect against heart disease. Cardiovascular disease (CVD) is relatively common in industrialised societies. Problems occur when blocked arteries cause restriction of the blood supply to heart muscle. The most common cause of blockage is the development of complex atheromatous plaques , composed of inflamed tissues and fatty deposits on the inner surface of the artery. These plaques develop slowly over time and may cause chronic restriction of blood flow leading to pain on exertion (angina) or acute blockage. This most often occurs when the irregular, inflamed surface of the plaque leads to the formation of a blood clot. When this occurs a region of heart muscle is suddenly deprived of blood and is damaged. This is what is known as a heart attack. If the damage is relatively limited the heart can recover but major damage can lead to death. Similar degeneration of arteries in the brain leads to loss of blood supply and stroke or death. Smoking and high levels of blood cholesterol, associated with high intakes of saturated fat, are both major risk factors for CVD and stroke. The accumulation of cholesterol as deposits within atheromateous plaques may be accelerated by oxidative damage to the low density lipoproteins (LDL). Such damage might be prevented by high intakes of antioxidants. 11. Read and translate the text. Other factors in fruits and vegetables Amounts of minerals and other micro-nutrients contained in fruits and vegetables depends on variety, climate, cultivation and soil type. The standard health advice is to eat a wide variety of different foods, thus making sure that we get all the components necessary for good health. Dietary fibre is the complex carbohydrate component of plant food which is not digested by enzymes in the digestive tract and which finds its way to the large bowel. There are several categories of fibre, some of which occur in fruit and vegetables. One example of soluble fibre, pectin, occurs in fruit, particularly citrus fruit and apples. Pectin slows down sugar absorption, decreases blood lipids and can bind some toxins. Insoluble fibre, found in many fruits and vegetables, has a high water retention capacity and acts as a bulking agent in the bowel and aids transit time. Research shows that eating fibre helps to protect against a number of disorders of the digestive tract including bowel cancer (6,8). Most of the fibre we eat comes from cereals. Fibre associated with low glycaemic index foods is important in the management of diabetes, sources include beans and lentils. Very young infants should not be given fibre. Fruits, vegetables and cereals must be introduced carefully as part of a proper weaning programme. 12. Define the meaning of new words. Flavonoids and other pigments. Pigments provide colour to food and make it more attractive. There are thousands of known plant pigments, including flavonoids, carotenoids and anthocyanins. Flavonoids are phenolic compounds which occur in all fruits and vegetables. Cherries, red grapes, green beans, red and yellow onions, apples, broccoli and tea are major sources. Flavonoids have known antioxidant activities in vitro and their potential role as antioxidants in vivo is being studied extensively. Anthocyanins are found in berries and cherries, they may help to reduce the risk of heart disease by inhibiting cholesterol formation. Protective factors in green vegetables. Green vegetables contain a mix of antioxidant vitamins, flavonoids and other compounds which give protection against cancer and heart disease. The phytochemicals, sinigrin and sulphoraphane are amongst the best studied. Brussels sprouts contain a chemical called sinigrin which suppresses the development of pre-cancerous cells. The breakdown product of sinigrin, allyl isothiocyanate, is responsible for the characteristic smell of sprouts and is the active ingredient. It works by persuading precancerous cells to commit suicide by a natural process called apoptosis. The effect is very powerful, just an occasional meal with sprouts could destroy all pre-cancerous cells in the colon. Broccoli contains sulphoraphane which also has powerful anti-cancer effects but, unlike sinigrin, it works by blocking cancer rather than suppressing it. Sulphoraphane works by stimulating part of the body's own detoxification system known as phase II enzymes. Other vegetables of the brassica family, including cabbage, cauliflower and kale have useful amounts of protective phytochemicals. 13. Make a plan of the text written above. In conclusion The action of protective factors in fruits and vegetables is complex. It is thought that the components reinforce one another and that we get best overall protection by eating a wide range of fruits and vegetables. In addition to the different composition of various types of fruits and vegetables we also have to consider other factors. These include, whether the compounds are in a form which the body can use (bioavailabilty) and the effects of normal methods of food storage, preparation and cooking. For example, vitamin C is easily destroyed by heat in cooking whereas the absorption of carotenoids is helped by the softening effects of cooking. What we eat does affect our health, we need to eat some foods from each of four main groups every day. These groups are, starchy foods which include bread, pasta, rice, breakfast cereals and potatoes, dairy products which include milk, cheese and yogurt, meat and fish and fruits and vegetables. Eat plenty of fruit and vegetables. Try to eat at least five portions of fruits and vegetables every day. Fruits and vegetables contain a lot of different compounds which help to keep us fit and well. Eat a wide range of fruits and vegetables to get maximum benefit. 14. Read the text. Define meaning of new words. A vegetarian is someone living on a diet of grains, pulses, nuts, seeds, vegetables and fruits with or without the use of dairy products and eggs. A vegetarian does not eat any meat, poultry, game, fish, shellfish or crustacea, or slaughter by-products. Types of Vegetarian Lacto-ovo-vegetarian. Eats both dairy products and eggs. This is the most common type of vegetarian diet. Lacto-vegetarian. Eats dairy products but not eggs. Vegan. Does not eat dairy products, eggs, or any other animal product. Stumbling Blocks Many foods contain ingredients derived from the slaughter of animals. Gelatine is made from animal ligaments, tendons, bones etc which have been boiled in water. It is often found in confectionery, low fat spreads and desserts, and other dairy products. The term animal fat refers to carcass fat and may be present in a wide range of foods, including biscuits, cakes, and margarines. Suet and lard are types of animal fats. Certain food additives (E numbers) may be derived from animal sources. Cheese is often made with rennet extracted from the stomach lining of slaughtered calves. Vegetarian cheese is made with rennet from a microbial source. The Vegetarian Society has an information sheet listing ingredients which may be unsuitable for vegetarians. Many vegetarians that eat eggs will eat only free-range eggs. This is due to moral objections to the battery farming of hens. The Vegetarian Society only endorses products containing eggs if the eggs are certified as free-range. Practices in catering Vegetarians dining out will expect work surfaces and chopping boards, utensils and all other kitchen equipment and facilities to be either kept separate from those used for nonvegetarian food preparation, or cleaned thoroughly before vegetarian food preparation. Caterers should also ensure that fryers, grills and griddles used for preparing nonvegetarian products are thoroughly cleaned. Fryers must be filled with fresh, uncontaminated oil before vegetarian food is cooked. The Society recommend that caterers keep a separate set of utensils for the preparation and serving of vegetarian meals. 15. Read and make summary. The Gluten-Free Diet A gluten-free diet is essential for people who have coeliac disease or dermatitis herpetiformis (a gluten induced skin sensitivity). Some people may choose to follow a glutenfree diet for other reasons, although these two diseases are the only ones where a gluten-free diet is considered medically imperative. Gluten is a mixture of proteins found in some cereals, particularly wheat. It is the gliadin component of gluten which is responsible for coeliac disease. A gluten-free diet is not the same as a wheat-free diet, and some gluten-free foods are not wheat free. Despite a good deal of research, it is unknown how or exactly why gluten harms the gut. It is now considered likely that coeliac disease involves an abnormal immunologic response, rather than an enzyme deficiency as was suggested in the past. The Vegetarian Society believes that a gluten-free diet is compatible with vegetarianism. Some doctors and The Coeliac Society advise against a vegetarian or vegan diet for coeliacs because they believe it may make your diet too complicated and this could mean it is difficult to comply with. There are no known medical or nutritional reasons why you should not be a vegetarian or vegan coeliac, although the gluten-free aspects of your diet must be the priority for your own health and well-being. It is possible to follow a gluten-free vegan diet, although you must be extra careful to ensure that your diet is nutritionally adequate. It is essential that you seek the advice of a sympathetic dietitian if you want to follow a vegan gluten-free diet. Vegetarians may initially find it difficult to establish what foods they can and cannot have. This Information Sheet is designed to help. A gluten-free diet involves the complete avoidance of all foods made from or containing wheat, rye, barley and usually, oats. Some doctors say oats may be permitted, although The Coeliac Society advise against the inclusion of oats in a gluten-free diet. The Coeliac Society publishes a list of gluten-free manufactured products in a booklet which is updated every year. You can check with The Vegetarian Society if you are unsure whether any particular foods on this list are suitable for vegetarians or vegans. Some manufacturers use the gluten-free symbol on their label. A wide range of specially manufactured gluten-free foods such as, bread, bread mix, pasta, biscuits, cakes, crispbread and flour are prescribable under the NHS. Some groups of people are exempt from prescription charges, children, pregnant women and pensioners in particular. If you are not exempt, it works out economical to buy a "season ticket" type prescription. Some gluten-free products, such as chocolate biscuits, are considered luxuries and are not prescribable, although they can be bought from the chemist. Coeliac disease leads to severe damage of the gut surface, which can be completely reversed by following a gluten-free diet. Shortly after the diagnosis of coeliac disease, you need to be extra careful to ensure you have a nutritionally adequate diet, as you may have been suffering from malabsorption of nutrients. 16. Read and fill in the table according to the content. Protein Some gluten-free flours are low in protein, because they have had the gluten removed, which is itself a protein. Specially manufactured, prescribed gluten-free flours usually have milk protein added. Vegetarians can get protein from nuts & seeds, pulses, the non-gluten containing cereals, soya products, milk, cheese and free range eggs. Make sure some protein is included in each meal, and practice protein complementation with the vegetable proteins, for example, combine a nut or pulse dish with a suitable cereal. Protein is especially important to a growing child, it is essential to seek the advice of your dietitian if you are bringing up a child on a gluten-free vegetarian or vegan diet. Anaemia Following diagnosis, many coeliacs sufferers are anaemic. This is usually due to iron deficiency, although it could also be due to folic acid or vitamin B12 deficiency. Your doctor may prescribe an iron supplement for you until your digestive system is back to normal and can absorb iron again. To ensure a good intake of iron include pulses, lentils, nuts and green vegetables daily in your diet. Avoid drinking tea with meals and instead have fruit juice, which helps the absorption of iron because it contains vitamin C. Going vegetarian If you are already a vegetarian or vegan and are advised to follow a gluten-free diet, you do not need to abandon your vegetarianism. If you are recently diagnosed and would like to become vegetarian or vegan, do give your digestive system time to recover before making major changes to your diet, after all, you have a lot to think about in getting used to a glutenfree diet. When you have stabilised, you can gradually change to a vegetarian diet. Do contact The Vegetarian Society if you have any problems, when making the change to a vegetarian way of living. Also, do contact us if you have any difficulties with health professionals, who are sceptical about your following a vegetarian diet. Once coeliac disease has been diagnosed, it is recommended that you follow a glutenfree diet for life. 17. Read the text. Translate and write out new words. A vegan is a strict vegetarian who does not eat any dairy products or eggs. Most vegans do not eat honey. A well balanced vegan diet can provide all the essential nutrients you require and shares the same health advantages as a vegetarian diet. Nutritional guidelines for vegans are essentially similar to those for vegetarians. However, vegetarians gain certain nutrients from dairy products and eggs. Vegans need to ensure their diets contain plant food sources of these nutrients, the main ones of which are discussed below. Protein Obtaining adequate protein on a vegan diet is not a problem. Nuts & seeds, pulses, wholegrain and grain products and soya products all supply protein. Previously, it has been thought that plant proteins are of a lower quality than animal proteins in terms of their essential amino acid content. However, this is no longer regarded as a problem and eating a balanced diet of plant foods will provide all the essential amino acids in adequate amounts. Essential Fatty Acids There are two essential fatty acids which must be supplied by the diet. These are linoleic acid and a-linolenic acid. Essential fatty acids are important for cell membrane function, cholesterol metabolism and the synthesis of various metabolites. Good sources of essential fatty acids are vegetable oils. It is important to have the correct balance between linoleic acid and a-linolenic acid. It has been suggested that vegans should use soyabean or rapeseed oils rather than sunflower or corn oils as these help give a better dietary balance. Vitamin B2 (Riboflavin) Certain studies have found vegans to have a low intake of the vitamin, riboflavin. Riboflavin is important in converting protein, fats and carbohydrates into energy, and the synthesis and repair of body tissues. Good sources of riboflavin include whole grains, mushrooms, almonds, leafy green vegetables and yeast extracts. Vitamin B12 Vitamin B12 is found primarily in meat, dairy products and eggs and is absent from plant foods. Considerable research has been carried out into possible plant sources of B12. Fermented soya products, seaweeds and algae such as spirulina have all been proposed as containing significant amounts of B12. However, the present consensus is that any B12 present in plant foods is likely to be in a form unavailable to humans and so these foods should not be relied upon as safe sources. Vitamin B12 is important in the formation of red blood cells and the maintenence of a healthy nervous system. When deficiency does occur it is more likely to be due to a failure to absorb B12 from the intestine than a dietary deficiency. Vegans can obtain B12 from a wide range of foods which have been fortified with the vitamin. These include certain yeast extracts, veggieburger mixes, breakfast cereals, vegetable margarines and soya milks. You should check the packaging to see which individual products are fortified with B12. Vitamin D Vitamin D is present in oily fish, eggs and dairy products in variable amounts. It is not found in plant foods. However, vegans can obtain vitamin D from vegetable margarines, some soya milks and certain other foods which are fortified with the vitamin. Vitamin D is also synthesised by the skin when exposed to sunlight. Synthesis of vitamin D in this way is usually adequate to supply all the body's requirements. Most vegans will obtain sufficient vitamin D providing they spend time outdoors on bright days. Fortified foods further ensure adequate amounts. Vegans who may be confined indoors may be recommended a vitamin D supplement. Also, infants who are seldom oudoors or who are dark-skinned may require supplements. Asian vegans may also be at risk of deficiency, particularly Asian women who may be required to keep their skin covered for cultural reasons. Calcium The major source of calcium in British diets is generally milk and dairy products. Vegans can obtain adequate calcium from plant foods. Good sources include tofu, leafy green vegetables, watercress, dried fruit, seeds and nuts. Also, white bread is fortified with calcium, as are some soya milks. Hard water can also provide significant amounts of calcium. Iodine Milk is the primary source of iodine in the British diet and studies have indicated some vegans may have a low iodine intake. Seaweeds are a good source of iodine, and vegetables and grains can contain iodine depending on the amounts in the soil. Infants It is perfectly possible to bring up a child on a vegan diet. Vegan children should be given plenty of nutrient rich foods and need good sources of protein, calcium, vitamin B12 and vitamin D. High fibre foods can fill up a child without filling their nutritional needs as well as interfering with mineral absorption from the intestine. For these reasons, foods high in fibre shouldn't be overused. Vegan Storecupboard Dairy products can largely be replaced with various soya products. There are several brands of soya milk. It can be purchased either sweetened or unsweetened, plain or flavoured. Different brands may be fortified with vitamin B12, vitamin D and calcium. Soya cheeses, yoghurts and cream are all available from health food stores. Eggs can be replaced in recipes by commercial egg replacer products, also available from health food stores. The Vegan Society's Animal-Free Shopper is a useful guide for vegan shoppers and includes suitable cosmetics, supplements, clothing and various household goods as well as food products. Food industry The food industry is the complex, global collective of diverse businesses that together supply much of the food energy consumed by the world population. Only subsistence farmers, those who survive on what they grow, can be considered outside of the scope of the modern food industry. The food industry includes: Regulation: local, regional, national and international rules and regulations for food production and sale, including food quality and food safety, and industry lobbying activities Education: academic, vocational, consultancy Research and development: food technology Financial services insurance, credit Manufacturing: agrichemicals, seed, farm machinery and supplies, agricultural construction, etc. Agriculture: raising of crops and livestock, seafood Food processing: preparation of fresh products for market, manufacture of prepared food products Marketing: promotion of generic products (e.g. milk board), new products, public opinion, through advertising, packaging, public relations, etc Wholesale and distribution: warehousing, transportation, logistics Retail: supermarket chains and independent food stores, direct-to-consumer, restaurant, food services Essentially, the food industry involves the commercial movement of food from field to fork. The modern food industry is the result of technological and cultural changes that have occurred over the last 150 years. Traditionally, over thousands of years, food production was centered around two activities: Labor-intensive agricultural activities, the farming of grain, produce and livestock; Personal food preparation, where individuals and families acquire raw and minimally processed ingredients, and prepare them for their own consumption. A significant percentage of the population was directly involved in farming, and in the process, many people actually fed themselves, from field to table. By contrast, the modern food industry relies far more on technology, particularly on mechanization and biochemistry, than on human and animal labor. In this way, food is raised, manipulated, preserved and moved around, resulting in a food industry that is to a great degree global in nature, with food and related resources travelling great distances. For example, farm machinery and parts from Europe and agrichemicals from the US may routinely travel to farms in South America, where farm products are raised and shipped to North America for fresh market consumption, or for use in processed foods which may then travel to further points around the world. The point at which foods are gathered and prepared has also become fragmented: much of what we eat has already been assembled for consumption. This modern food system relies heavily on technology, transportation, management and logistics for physical fulfillment, and on marketing and government regulation for maintaining an efficient consumer market. An incredibly wide range of businesses and individuals are employed by and profit from all aspects of this huge and complex system. A tremendous amount of governmental regulation and administration is also involved in this continual flow of materials, food products, and related information. Food industry is not a formally defined term, however, it is usually used in a broadly inclusive way to cover all aspects of food production and sale. The Food Standards Agency, a government body in the UK, describes it thus: "...the whole food industry – from farming and food production, packaging and distribution, to retail and catering." The Economic Research Service of the USDA uses the term food system to describe the same thing: "The U.S. food system is a complex network of farmers and the industries that link to them. Those links include makers of farm equipment and chemicals as well as firms that provide services to agribusinesses, such as providers of transportation and financial services. The system also includes the food marketing industries that link farms to consumers, and which include food and fiber processors, wholesalers, retailers, and foodservice establishments." Processed food sales worldwide are approximately US$3.2 trillion (2004). In the U.S., consumers spend approximately US$1 trillion annually for food, or nearly 10 percent of the Gross Domestic Product (GDP). Over 16.5 million people are employed in the food industry. Agriculture is the process of producing food, feed, fiber and other desired products by the cultivation of certain plants and the raising of domesticated animals (livestock). The practice of agriculture is also known as "farming", while scientists, inventors and others devoted to improving farming methods and implements are also said to be engaged in agriculture. More people in the world are involved in agriculture as their primary economic activity than in any other, yet it only accounts for four percent of the world's GDP. A vast global transportation network is required by the food industry in order to connect its numerous parts. These include suppliers, manufacturers, warehousing, retailers and the end consumers. With populations around the world concentrating in urban areas, food buying is increasingly removed from all aspects food production. This is a relatively recent development, taking place mainly over the last 50 years. The supermarket is a defining retail element of the food industry, where tens of thousands of products are gathered in one location, in continuous, year-round supply. Food preparation is another area where change in recent decades has been dramatic. Today, two food industry sectors are in apparent competition for the retail food dollar. The grocery industry sell fresh and largely raw products for consumers to use as ingredients in home cooking. The food service industry offers prepared food, either as finished products, or as partially prepared components for final "assembly". Sophisticated technologies define modern food production. They include many areas. Agricultural machinery, originally led by the tractor, has practically eliminated human labor in many areas of production. Biotechnology is driving much change, in areas as diverse as agrichemicals, plant breeding and food processing. Many other areas of technology are also involved, to the point where it is hard to find an area that does not have a direct impact on the food industry. Computer technology is also a central force, with computer networks and specialized software providing the support infrastructure to allow global movement of the myriad components involved. As consumers grow increasingly removed from food production, the role of product creation, advertising, publicity become the primary vehicles for information about food. With processed food as the dominant category, marketers have almost infinite possibilities in product creation. The smooth flow of international trade is critical to the functioning of the modern food industry. Government regulations have to be synchronized to some greater degree to allow this. Until the last 100 years, agriculture was labor intensive. Farming was a common occupation. Food production flowed from millions of farms. Farmers, largely trained from generation to generation, carried on the family business. That situation has changed dramatically. In North America, over 50% of the population were farm families only a few decades ago; now, that figure is around 1-2%, and some 80% of the population lives in cities. The food industry as a complex whole requires an incredibly wide range of skills. Several hundred occupation types exist within the food industry. Research in agricultural and food processing technologies happens in great part in university research environments. Projects are often funded by companies from the food industry. There is therefore a direct relationship between the academic and commercial sectors, as far as scientific research. The Food Worldis the biggest directory for food, beverage and agriculture industries, worldwide. Monsanto is a leading producer of pesticide, seeds, and other farming products. Both Archer Daniels Midland and Cargill process grain into animal feed and a diverse group of products. ADM also provides agricultural storage and transportation services, while Cargill operates a finance wing. Bunge is a global soybean exporter and is also involved in food processing, grain trading, and fertilizer. Dole Food Company is the world's largest fruit company.

Food Technology (magazine) Food Technology is a monthly food science and technology magazine published by the Institute of Food Technologists (IFT) in Chicago, Illinois. The magazine addresses current issues related to food science and technology, including research, education, food engineering, food packaging, nutraceuticals, laboratory issues, and other items related to IFT. The magazine is free to IFT members as part of their annual dues. Its current editor-in-chief is Bob Swientek, a position he has held since 2004. Before 1946, IFT would publish occasional newsletters and proceedings of papers presented at the annual IFT Meetings from 1940 to 1945. By 1946, the IFT Council (its governing body) decided to publish a monthly journal on the proceedings of the 1946 Annual Meeting. The first issue of Food Technology magazine was published in January 1947 with C. Olin Ball as its editor-in-chief. This journal published both information regarding the food industry along with research papers. The journal would become a monthly publication beginning in 1949, carrying magazine advertisements for the first time. Ball would remain as editor-in-chief until June 1950. Zoltan I. Kertesz would succeed Ball as editor-in-chief in 1950 and hold that position until July 1952. While Kertesz served as editor, IFT would purchase Food Research in 1951 from Garand Press. Martin S. Peterson would succeed Kertesz as editor-in-chief that year and continue in that position until December 1960. During Peterson's tenure, Food Technology would undergo two new logo and cover designs, occurring in June 1953 and August 1957, respectively. During this time, both Kertesz and Peterson would also be Editor-In-Chief of Food Research. George F. Stewart succeeded Peterson as editor of Food Technology in January 1961. It was also the time that Calvert L. Willey took over as Executive Secretary of IFT. During this time, Stewart and Willey worked together to shift the basic research to the Journal of Food Science (changed from Food Research in 1961). The formatting of Food Technology was changed to publish more feature articles, news, and applied research. Stewart would remain as Executive Editor until July 1966. By this time, Willey had centralized the publications office in Chicago, establishing a Director of Publications with Karl O. Herz. Stewart would be succeeded by Walter M. Urbain as Scientific Editor of Food Technology in May 1966. The magazine would also have a new logo and cover design in June 1969. The final transitions would occur in 1970 and 1971 when John B. Klis succeeded Herz as Publications Director and Editor of Food Technology in April 1970, and when Ernest J. Briskey succeeded Urbain as Scientific Editor in June 1970. Applied research of food science would transfer fully from Food Technology to the Journal of Food Science in January 1971 where they have remained ever since. During this time, Stewart, Urbain, and Briskey would also remain as Editor-InChief of the Journal of Food Science as well until 1971. Klis saw the magazine's greatest change from 1971 until he stepped down in March 1996. During this time, Food Technology would change its logo and cover design twice, first in January 1977 and then in June 1985. The 1977 change would also show an overview being introduced that highlighted outstanding symposia in food science and technology from the IFT Annual Meeting, a trend that would continue until 1997. Klis would serve until 1996 and would be succeeded by Frances R. Katz in September of that year. Katz would serve as editor from September 1996 to March 2001 when she was succeeded by Neil H. Mermelstein, a member of the Food Technology staff since 1971. In October 2004, Mermelstein took a new position as Executive Editor, and Bob Swientek became Editor-In-Chief. The magazine has since undergone two changes in its publishing logo and format, the first in June 1997 and the most recent change occurring in July 2005, winning awards for the redesign. Today the magazine presents two to three featured articles, including education, foodservice, product development, and pet food in the most recent issues, and standard articles on laboratory, ingredients, nutraceuticals, food processing, food packaging, and items related to IFT. Such topics covered by Food Technology since 1947 include quality, food safety, regulation, food law, sensory analysis, food chemistry, food microbiology, food additive, food allergy, education, food labeling regulations, bioterrorism, and obesity. DAIRY PRODUCTS IN HUMAN NUTRITION Milk and dairy products are accepted in many countries as basic foods, some of which persons of all ages should have every day. The precise role of the milk components- protein, fat, lactose or carbohydrate, and minerals- in human nutrition is still incompletely understood. But these essential elements of a balanced diet are combined in the proportions and amounts needed for the growth of infants and children and for the dietary well-being of an adult. One pint of summer milk contributes about 90 percent of the calcium, 30 to 40 percent of the riboflavin, 25 to 30 percent of the protein, 10 to 20 percent of the calories and vitamins A and D, and up to 10 percent of the iron and vitamine D needed by an adult. Milk protein is of high nutritional value, since it contains all the essential amino acids, those that cannot be synthesized in quantity. The nutritional value of milk fat is still unclear. It is the most complex of natural fats, containing at least 142 fatty acids. The exact nutritional function of lactose, or milk sugar, is not known. Lactose is hydrolysed in the body to glycose and galactose. A deficiency of these is thought to lead to diseases of structural and nervous tissue in latter life. The mineral content of milk includes calcium and phosphorus adequate for normal skeletal development. The dietary essential minerals that occur in major amounts in milk are, in grams per quart, chlorine 0.97, phosphorus 0.91, sulfur 0.28, and magnesium 0.11. Milk contains all of the vitamins known to be required by man. Food irradiation Food irradiation is the process of exposing food to ionizing radiation in order to destroy microorganisms, bacteria, viruses, or insects that might be present in the food. Further applications include sprout inhibition, delay of ripening, increase of juice yield, improvement of re-hydration. Irradiation is a more general term of deliberate exposure of materials to radiation to achieve a technical goal. As such it is also used on non-food items, such as medical hardware, plastics, tubes for gas-pipelines, tires, and even gemstones. Food irradiation is sometimes referred to as cold pasteurization or electronic pasteurization because ionizing radiation used to sterilize the food does not heat the food to high temperatures during the process, as in heat-pasteurization (at a typical dose of 10 kGy, food that is physically equivalent to water would warm by about 2.5 °C). The treatment of solid food by ionizing radiation can provide an effect similar to heat pasteurization of liquids, such as milk. However, the use of the term, cold pasteurization, to describe irradiated foods is controversial, because pasteurization and irradiation are fundamentally different processes, although the intended end results can in some cases be similar. Food irradiation is currently permitted by over 40 countries and volumes are estimated to exceed 500 000 metric tons annually world wide. By irradiating food, depending on the dose, some or all of the harmful bacteria and other pathogens present are killed. This prolongs the shelf-life of the food in cases where microbial spoilage is the limiting factor. Some foods (e.g., herbs and spices) are irradiated at sufficient doses (five kilograys or more) to reduce the microbial counts by several orders of magnitude; such ingredients will not carry over spoilage or pathogen microorganisms into the final product. It has also been shown that irradiation can delay the ripening of fruits or the sprouting of vegetables. The United States Department of Agriculture has approved the use of low-level irradiation as an alternative treatment to pesticides for fruits and vegetables that are considered hosts to a number of insect pests, including fruit flies and seed weevils; US FDA has cleared among a number of other applications the treatment of hamburger patties to eliminate the residual risk of a contamination by a virulent E. coli. The United Nations Food and Agricultural Organization (FAO) has passed a motion to commit member states to implement irradiation technology for their national phytosanitary programs; the General assembly of the International Atomic Energy Agency (IAEA) has urged to make wider use of the irradiation technology; the World Health Organization (WHO) has complained that food irradiation is not available to those who need it most because of reluctance and opposition in some developed countries. And the USDA has made a number of bi-lateral agreements with developing countries to facilitate the imports of exotic fruits and to simplify the quarantine procedures. Currently, the European Union has regulated processing of food by ionizing radiation in specific directives since 1999; the situation is easily explored and the several documents and reports are accessible. The 'implementing' directive contains a 'positive list' only permitting irradiation of dried aromatic herbs, spices, and vegetable seasonings. However, any Member State is permitted to maintain previously granted clearances or to add new clearance as granted in other Member States, in the case the EC's Scientific Committee on Food (SCF) has given a positive vote for the respective application. Presently, six Member States (Belgium, France, Italy, Netherlands, Poland, United Kingdom) have adopted such provisions. Because of the 'Single Market' of the EC, any food--even if irradiated--must be allowed to be marketed in any other Member State even if a general ban of food irradiation prevails, under the condition that the food has been irradiated legally in the state of origin. Furthermore, imports into the EC are possible from third countries if the irradiation facility had been inspected and licensed by the EC and the treatment is legal within the EC or some Member state . The Scientific Committee on Food (SCF) of the EC has given a positive vote on eight categories of food to be irradiated. However, in a compromise between the European Parliament and the European Commission, only dried aromatic herbs, spices, and vegetable seasonings can be found in the positive list. The European Commission was due to provide a final draft for the positive list by the end of 2000; however, this failed because of a veto from Germany and a few other Member States. In 1992 and in 1998 the SCF voted positive on a number of irradiation applications which had been allowed in some Member States before the EC Directives came into force, in order to enable those Member States to maintain the national authorizations. In 2003 (at the occasion when Codex Alimentarius was about to remove any upper dose limit for food irradiation) the SCF adopted a 'revised opinion which in fact is just a re-confirmation and endorsement of the 1986-opinion. The cancellation of the upper dose limit is denied, and before the actual list of individual items or food classes (as in the opinions expressed in 1986, 1992 and 1998) is expanded, new individual studies into the toxicology of each of such food and for each of the proposed dose ranges is requested. After 2003 the SCF has been replaced by the new European Food Safety Authority (EFSA), which not yet has voted on processing food by ionizing radiation. Other countries including New Zealand, Australia, Thailand, India, and Mexico have permitted the irradiation of fresh fruits for fruit fly quarantine purposes amongst others. Other countries as Pakistan and Brazil have adopted the Codex Alimentarius Standard on Irradiated Food without any reservation or restriction, ie. any food to any dose. The dose of radiation is measured in the SI unit known as Gray (Gy). One Gray (Gy) dose of radiation is equal to 1 joule of energy absorbed per kg of food material. In radiation processing of foods, the doses are generally measured in kGy (1000 Gy). The measurement of radiation dose is referred to as dosimetry and it involves exposing dosimeters jointly with the treated food item. Dosimeters are small components attached to the irradiated product made of materials that when exposed to ionizing radiation change specific measureable physical attributes to a degree that can be correllated to the dose received. Modern dosimeters are made of a range of materials such as alanine pellets, perspex blocks, radiochromic films, as well as special solutions. These dosimeters are used in combination with specialized read out devices. Standards that describe calibration and operation for radiation dosimetry are maintained by the American Society for Testing and Materials (ASTM international) and are also available as ISO/ASTM standards. On the basis of the dose of radiation the application is generally divided into three main categories as detailed under: Low Dose Applications (up to 1 kGy) Sprout inhibition in bulbs and tubers 0.03-0.15 kGy Delay in fruit ripening 0.25-0.75 kGy Insect disinfestation including, quarantine treatment and elimination of food borne parasites 0.07-1.00 kGy Medium Dose Applications (1 kGy to 10 kGy) Reduction of spoilage microbes to improve shelf-life of meat, poultry and seafoods under refrigeration 1.50-3.00 kGy Elimination of pathogenic microbes in fresh and frozen meat, poultry and seafoods 3.007.00 kGy Reducing number of microorganisms in spices to improve hygenic quality 10.00 kGy High Dose Applications (above 10 kGy) Sterilisation of packaged meat, poultry and their products which are shelf stable without refrigeration. 25.00-70.00 kGy Sterilisation of Hospital diets 25.00-70.00 kGy Product improvement as increased juice yield or improved re-hydration It is important to note that these doses are above those currently permitted for these food items by the FDA and other regulators around the world. The Codex Alimentarius Standard on Irradiated Food does not specify any upper dose limit. NASA is authorized to sterilize food for Astronauts at doses of 44 kGy as a notable exception. Irradiation treatments are also sometimes classified as radappertization,radicidation and radurization. Electron irradiation uses electrons accelerated in an electric field to a velocity close to the speed of light. Electrons are particulate radiation and have cross section many times larger than photons, so that they do not penetrate the product beyond a few inches depending on product density. Electron facilities rely on substantial concrete shields to protect workers and the environment from radiation exposure. Gamma radiation is radiation of photons in the gamma part of the spectrum. The radiation is obtained through the use of radioisotopes, generally Cobalt-60 or, in theory, Caesium-137. Caesium-137 is recovered during the refinement of spent nuclear fuel. Because this technology - except for military applications - is not commercially available, insufficient quantities of it are available on the global isotope markets for use in large scale, commercial irradiators. Presently, Caesium-137 is used only in small hospital units to treat blood before transfusion to prevent Graft-versus-host disease. Food irradiation using Cobalt-60 is the preferred method by most processors, because the better penetration enables administering treatment to entire industrial pallets or totes, reducing the need for material handling. A pallet or tote is typically exposed for several minutes depending on dose. Radioactive material must be monitored and carefully stored to shield workers and the environment from its gamma rays. With most designs the radioisotope can be lowered into a water-filled source storage pool to allow maintenance personnel to enter the radiation shield. In this mode the water in the pool absorbs the radiation. Other uncommonly used designs feature dry storage by providing movable shields that reduce radiation levels in areas of the irradiation chamber. One variant of gamma irradiators keeps the Cobalt-60 under water at all times and lowers the product to be irradiated under water in hermetic bells. No further shielding is required for such designs. Similar to gamma radiation, X-rays are photon radiation of a wide energy spectrum and an alternative to isotope based irradiation systems. X-rays are generated by colliding accelerated electrons with a dense material such as Tantalum in a process known as bremsstrahlung-conversion. X-ray irradiators are scalable and have good penetration, with the added benefit of using an electronic source that stops radiating when switched off. They also permit very good dose uniformity. However, these systems generally have low energetic efficiency during the conversion of electron energy to photon radiation requiring much more electrical energy than other systems and longer exposure times than those required by gamma rays or electron beams. Like most other types of facilities, X-ray systems rely on concrete shields to protect the environment and workers from radiation. Many U.S. supermarkets carry irradiated food products today ranging from fresh tropical fruit from Hawaii or Florida, dehydrated spices and ground meat products. Certain supermarkets like Whole Foods Market prefer not carry the product for reasons of consumer perception. Some older studies suggest that majority of the public questions the safety of irradiated foods, and if given a choice, will not buy foods that have been irradiated. More recent consumer attitude and markets studies worldwide, however, indicate consumers today will tend to accept irradiated food. Major studies in the United States indicate the number of consumers concerned about the safety of irradiated food has decreased in the last 10 years and continues to be less than the number of those concerned about pesticide residues, microbiological contamination, and other food-related concerns. Where ever irradiated food has reached the market, it has found a sufficient number of consumers to buy it. A number of marketing tests has proven, that consumers as soon as they are allowed to try the real irradiated food item and are informed about the technology and the purpose of the treatment are willing to buy. The number of people reporting no concerns about irradiated food is among the lowest for food issues, comparable to that of people with no concern about food additives and preservatives. Opponents of food irradiation sometimes state that large-scale irradiation would increase processing, transportation, and handling times for fruits and vegetables thus contributing to a negative ecological balance compared to locally grown foods. Labeling laws differ from country to country. While Codex Alimentarius represents the global standard in particular under the WTO-agreement, member states are free to convert those standards into national regulations. With regard to labelling of irradiated food detailed rules are published at CODEX-STAN - 1 (2005) labelling of prepacked food. The provisions are that any 'first generation' product must be labelled 'irradiated' as any product derived directly from an irradiated raw material; for ingredients the provisions is that even the last molecule of an irradiated ingredient must be listed with the ingredients even in cases where the unirradiated ingredient will not appear on the label. The RADURA-logo is optional; several countries use a graphical version which differs from the Codex-version. In the US as in many other countries irradiated food must be labeled as "Treated with irradiation" or "Treated by radiation" and require the usage of the Radura symbol at the point of sale. However, the meaning of the label is not consistent. The amount of irradiation used can vary and since there are no published standards, the amount of pathogens affected by irradiation can be variable as well. In addition, there are no regulations regarding the levels of pathogen reduction that must be achieved. Food that is processed as an ingredient by a restaurant or food processor is exempt from the labeling requirement. FDA is currently proposing a rule that in some cases would allow certain irradiated foods to be marketed without any labeling at all. Under the new rules, only those irradiated foods in which the irradiation causes a material change in the food, or a material change in the consequences that may result from the use of the food, would bear the Radura symbol and the term "irradiated", or a derivative thereof, in conjunction with explicit language describing the change in the food or its conditions of use. In the same rule FDA is proposing to permit a firm to use the terms "electronically pasteurized" or "cold pasteurized" in lieu of "irradiated", provided it notifies the agency that the irradiation process being used meets the criteria specified for use of the term "pasteurized". There are analytical methods available to detect the usage of irradiation on food items in the marketplace. This is understood as a tool for government authorities to enforce existing labeling standards and to bolster consumer confidence. The European Union is particularly strict in enforcing irradiation labeling requiring its member countries to perform tests on a cross section of food items in the market-place and to report to the European Commission; the results are published annually in the OJ of the European Communities. Hundreds of animal feeding studies of irradiated food, including multigenerational studies, have been performed since 1950. Endpoints investigated have included subchronic and chronic changes in metabolism, histopathology, and function of most systems; reproductive effects; growth; teratogenicity; and mutagenicity. Because a large number of studies has been performed, some have demonstrated adverse effects of irradiation, but no consistent pattern has emerged. Independent reviews of the scientific evidence by a series of expert committees, involving the UN Food and Agriculture Organization (FAO), the International Atomic Energy Agency (IAEA), the World Health Organization (WHO) and the International Consultative Group on Food Irradiation (ICGFI), as well as the FDA have concluded that irradiation of foods under specified conditions is safe. Some consumer advocacy groups like Public Citizen or Food and Water Watch maintain that the safety of irradiated food is not proven and strongly oppose the use of the technology. Concerns have sometimes been expressed by public interest groups and public health experts that irradiation, as a non-preventive measure, might disguise or otherwise divert attention away from poor working conditions, sanitation, and poor food-handling procedures that lead to contamination in the first place. Processors of irradiated food are subject to all existing regulations, inspections, and potential penalties regarding plant safety and sanitization; including fines, recalls, and criminal prosecutions. Furthermore, while food irradiation can in some cases maintain the quality of certain perishable food for a longer period of time, it can not undo spoilage effects that occur prior to irradiation. Irradiation can therefore not be successfully used to mask quality issues other than pathogens. Under a HACCP-conzept Hazard Analysis and Critical Control Point radiation processing can serve and contribute as an ultimate CCP (Critical Control Point). Experience over more than 40 years in the field of radiation processing has shown that such technology is generally safely used. The steady improvement in the design of such facilities and careful selection and training of operators have contributed to a very good safety record. Nevertheless, there have been instances, as in Italy in 1975, in Norway in 1982 and in El Salvador in 1989, when safety systems have been circumvented and serious radiological accidents involving workers at the facilities have ensued. The safety of irradiation facilities is regulated by the United Nations International Atomic Energy Agency and monitored by the different national Nuclear Regulatory Commissions. The incidents that have occurred in the past are documented by the agency and thoroughly analyzed to determine root cause and improvement potential. Such improvements are then mandated to retrofit existing facilities and future design. National and international regulations on the levels and types of energy used to irradiate food generally set standards that prevent the possibility of inducing radioactivity in treated foods. Care must be taken not to expose the operators and the environment to radiation. Interlocks and safeguards are mandated to minimize this risk. Nevertheless there have been radiation related deaths and injury amongst workers of such facilities, many of them caused by the operators themselves overriding the interlocks. An incident in Decatur, Georgia where water soluble caesium-137 leaked into the source storage pool requiring NRC intervention has led to near elimination of this radioisotope; it has been replaced by the more costly, non-water soluble cobalt-60. Some foods, particularly fruits and vegetables, are naturally restricted from sale on the global market, unless they are irradiated to prolong quality for transportation. Less spoilage at the receiving end means fewer discards, lowering the unit cost. Irradiation has also been used to reduce bacteria counts in seafood that is shipped over long distances. Because irradiation can reduce pest infestations, it has opened the markets for previously prohibited items, such as mangoes from India that otherwise have a risk of carrying certain insects and pathogens with them into the importing country. Insect pests can have a devastating effect on crop production. They can also transmit diseases that destroy crops and kill livestock and people. Heavy reliance on pesticides raises environmental concerns and problems of pest adaptation and resistance. As a result, many countries are seeking to minimize insecticide use through irradiation techniques. Such benefits are offset by the cost of this rather capital intensive technology. The actual cost of food irradiation is influenced by dose requirements, the food's tolerance of radiation, handling conditions (i.e., packaging and stacking requirements), construction costs, financing arrangements, and other variables particular to the situation. Irradiation is a capital-intensive technology requiring a substantial initial investment, ranging from $1 million to $5 million. In the case of large research or contract irradiation facilities, major capital costs include a radiation source (cobalt-60), hardware (irradiator, totes and conveyors, control systems, and other auxiliary equipment), land (1 to 1.5 acres), radiation shield, and warehouse. Operating costs include salaries (for fixed and variable labor), utilities, maintenance, taxes/insurance, cobalt-60 replenishment, general utilities, and miscellaneous operating costs. Treatment costs vary as a function of dose and facility usage. Low dose applications such as desinfestation of fruit range between $US 0.01/lbs and $US 0.08/lbs while higher dose applications can cost as much as $US 0.20 / lbs. Other methods to reduce different pathogens in food include pasteurization, Ultra-high temperature processing, UV radiation, Ozone or fumigation with ethylene oxide. Insect pests can also be eliminated fumigation with methyl bromide or aluminum phosphine, vapour heat, forced hot air, hot water dipping, or cold treatment. However, the Mango weevil sitting in the stone of the fruit can only be reached by ionizing radiation. Other methods to extend shelf life of food items include modified atmosphere packaging, carbon monixide, dehydration, vacuum packaging, freezing and flash freezing as well as chemical additives. However, such methods are not effective for products already deep-frozen where only ionizing radiation can penetrate the product (without re-thawing). Some people argue that the best alternative to food irradiation to reduce pathogens is in good agricultural practices. For example, farmers and processing plants should improve sanitation practices, water used for irrigation and processing should be regularly tested for E. coli, and production plants should be routinely inspected. concentrated animal feeding operations near farmland where produce is grown should be regulated. However, such methods as also practised in organic farming can only reduce the extend of the load with microorganisms of all kind; a residual flora including pathogen germs will always persist; and processing by ionizing radiation could be the ultimate measure (as a CCP under a HACCPconcept) to practically eliminate such risks. The main organization in the United States regarding food science and food technology is the Institute of Food Technologists (IFT), headquarted in Chicago, Illinois, which is the US member organisation of the International Union of Food Science and Technology (IUFoST). The European national organisations are organised into the European Federation of Food Science and Technology (EFFoST). Some popular books on some aspects of food science or kitchen science have been written by Harold McGee and Howard Hillman. In the October 2006 issue of Food Technology, IFT President Dennis R. Heldman noted that the IFT Committee on Higher Education stated that the current definition the "Food Science is the discipline in which the engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public." Food and Agriculture Organization The Food and Agriculture Organization of the United Nations (FAO) is a specialized agency of the United Nations that leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information, and helps developing countries and countries in transition modernize and improve agriculture, forestry and fisheries practices, ensuring good nutrition and food security for all. Its Latin motto, fiat panis, translates into English as "let there be bread!". FAO was founded on 16 October 1945 in Quebec City, Quebec, Canada. In 1951 its headquarters were moved from Washington, D.C., United States, to Rome, Italy. As of 11 April, 2006, it had 190 members (189 states and the European Community, List of FAO members). FAO's mandate is to raise levels of nutrition, improve agricultural productivity, better the lives of rural populations and contribute to the growth of the world economy. Achieving food security for all is at the heart of FAO's efforts – to make sure people have regular access to enough high-quality food to lead active lives. FAO is governed by the Conference of Member Nations, which meets every two years to review the work carried out by the organization and approve a Programme of Work and Budget for the next biennium. The conference elects a council of 49 Member Nations to act as an interim governing body. Members serve three-year, rotating terms. The conference also elects the Director-General to head the agency. FAO is composed of eight departments: Administration and Finance, Agriculture, Economic and Social, Fisheries, Forestry, General Affairs and Information, Sustainable Development and Technical Cooperation. Since 1994, FAO has undergone the most significant restructuring since its founding, to decentralize operations, streamline procedures and reduce costs. Savings of $50 million a year have been realized. FAO's Regular Programme budget is funded by its members, through contributions set at the FAO Conference. This budget covers core technical work, cooperation and partnerships including the Technical Cooperation Programme, information and general policy, direction and administration. Member states froze FAO's budget from 1994 through 2001 at $650 million per biennium. The budget was raised slightly to $651.8 million for 2002-03 and jumped to $749 million for 2004-05, but this nominal increase was seen as a decline in real terms. In November 2005, the FAO governing Conference voted for a two-year budget appropriation of $765.7 million for 2006–2007; once again, the increase only partially offset rising costs due to inflation. The Special Program for Food Security (SPFS) is FAO's flagship initiative for reaching the goal of halving the number of hungry in the world by 2015 (presently 852 million people), as part of its commitment to the Millennium Development Goals. Through projects in over 100 countries worldwide, the SPFS promotes effective, tangible solutions to the elimination of hunger, undernourishment and poverty. Currently 102 countries are engaged in the SPFS and of these approximately 30 are operating or developing comprehensive National Food Security Programmes. To maximize the impact of its work, the SPFS strongly promotes national ownership and local empowerment in the countries in which it operates. During the 1990s, FAO took a leading role in the promotion of integrated pest management for rice production in Asia. Hundreds of thousands of farmers were trained using an approach known as the Farmer Field School (FFS)]. Like many of the programmes managed by FAO, the funds for Farmer Field Schools came from bilateral Trust Funds, with Australia, Netherlands, Norway and Switzerland acting as the leading donors. FAO's efforts in this area have drawn praise from NGOs that have otherwise criticized much of the work of the organization. The FAO Statistical Division produces FAOSTAT, an on-line multilingual database currently containing over 3 million time-series records from over 210 countries and territories covering statistics on agriculture, nutrition, fisheries, forestry, food aid, land use and population. The Statistical Division also produces data on World Agricultural Trade Flows. Raising awareness about the problem of hunger mobilizes energy to find a solution. In 1997, FAO launched TeleFood, a campaign of concerts, sporting events and other activities to harness the power of media, celebrities and concerned citizens to help fight hunger. Since its start, the campaign has generated close to US$14 million in donations. Money raised through TeleFood pays for small, sustainable projects that help small-scale farmers produce more food for their families and communities. FAO's Strategic Framework 2000-2015 stipulates that the organization is expected to take into full account "progress made in further developing a rights-based approach to food security" in carrying out its mission "helping to build a food-secure world for present and future generations." When the Council adopted the Voluntary Guidelines in November 2004, it also called for adequate follow up to the Guidelines through mainstreaming and the preparation of information, communication and training material. In June 2002, during the World Food Summit, world leaders reviewed progress made towards meeting the 1996 Summit goal of halving the number of the world's hungry by 2015; their final declaration called for the creation of an International Alliance against Hunger (IAAH) to join forces in efforts to eradicate hunger. Launched on World Food Day, 16 October 2003, the IAAH works to generate political will and concrete actions through partnerships between intergovernmental and non-governmental organizations and national alliances. The IAAH is a voluntary association of international organizations, national alliances against hunger, civil society organizations, social and religious organizations and the private sector. The global activities of the IAAH focus on four major themes: advocacy, accountability, resource mobilization and coordination. The International Alliance is made up of the Rome-based UN food organizations – FAO, the International Fund for Agricultural Development (IFAD) and the World Food Programme (WFP) – and representatives of other intergovernmental and non-governmental organizations. Individuals cannot directly join the IAAH, though they can work with national alliances against hunger. In less than two years, 36 countries have established national alliances, some of them already very active like those in Brazil, Burkina Faso, France, India and the United States. The FAO Goodwill Ambassadors Programme was initiated in 1999. The main purpose of the programme is to attract public and media attention to the unacceptable situation that some 800 million people continue to suffer from chronic hunger and malnutrition in a time of unprecedented plenty. These people lead a life of misery and are denied the most basic of human rights: the right to food. Governments alone cannot end hunger and undernourishment. Mobilization of the public and private sectors, the involvement of civil society and the pooling of collective and individual resources are all needed if people are to break out of the vicious circle of chronic hunger and undernourishment. Each of FAO’s Goodwill Ambassadors – celebrities from the arts, entertainment, sport and academia such as Nobel Prize winner Rita Levi Montalcini, actress Gong Li, singer Miriam Makeba, and soccer player Roberto Baggio, to name a few – has made a personal and professional commitment to FAO’s vision: a foodsecure world for present and future generations. Using their talents and influence, the Goodwill Ambassadors draw the old and the young, the rich and the poor into the campaign against world hunger. They aim to make Food for All a reality in the 21st century and beyond. See also FAO Goodwill Ambassadors There has been public criticism of FAO for at least 30 years. Dissatisfaction with the organization's performance was among the reasons for the creation of two new organizations after the World Food Conference in 1974, namely the World Food Council and the International Fund for Agricultural Development; by the early eighties there was intense rivalry among these organizations. At the same time, the World Food Programme, which started as an experimental 3-year programme under FAO, was growing in size and independence, with the Directors of FAO and WFP struggling for power. Edoaurd Saouma, the Director General of FAO, was heavily criticised in Graham Hancock's book 'Lords of Poverty, published in 1989. Mention is made of Saouma's 'fat pay packet', his 'autocratic' management style, and his 'control over the flow of public information'. Hancock concluded that "One gets the sense from all of this of an institution that has lost its way, departed from its purely humanitarian and developmental mandate, become confused about its place in the world - about exactly what it is doing, and why". In 1990, the US State Department expressed the view that "The Food and Agriculture Organization has lagged behind other UN organizations in responding to US desires for improvements in program and budget processes to enhance value for money spent". A year later, in 1991, The Ecologist magazine produced a special issue under the heading "The UN Food and Agriculture Organization: Promoting World Hunger". The magazine included articles that questioned FAO's policies and practices in forestry, fisheries, aquaculture, and pest control. The articles were written by experts such as Helena NorbergHodge, Vandana Shiva, Edward Goldsmith, Miguel A. Altieri and Barbara Dinham. Also included was an article by 'Khalil Sesmou', the pseudonym of a senior FAO official. Sesmou's article started with the following summary of the criticism FAO was facing at the time: "FAO, set up to develop world agriculture so as to enable the world to feed itself has disastrously failed in its task. It has ignored and even derided traditional agricultural methods and permits no international criticism of its policy of promoting Western-style intensive farming and the export of cash crops. FAO's performance is judged on the amount of money it spends, not on the effectiveness of its projects, it ignores the voices of the people it is supposed to be helping and it has close links with agribusiness internationals, whose products it actively promotes. The organization's Director-General has been much criticized by FAO staff and others for his autocratic style, and the political manoeuvring he has engaged in to ensure his re-election. A massive overhaul of FAO's basic philosophy, structure and function is urgently needed". In 1996, FAO organised the World Food Summit, attended by 112 Heads or Deputy Heads of State and Government. The Summit concluded with the signing of the Rome Declaration, which established the goal of halving the number of people who suffer from hunger by the year 2015. At the same time, 1,200 Civil Society Organisations (CSOs) from 80 countries participated in an NGO Forum. The Forum was critical of the growing industrialisation of agriculture and called upon Governments - and FAO - to do more to protect the 'Right to Food' of the poor, rather that protecting the profits of companies involved in agribusiness. The next Food Summit organised by FAO in 2002 was considered to be a waste of time by many of the official participants. Social movements, farmers, fisherfolk, pastoralists, indigenous peoples, environmentalists, women's organizations, trade unions and NGOs expressed their collective disappointment in, and rejection of the official Declaration of the Summit. In 2004, FAO produced a controversial report called 'Agricultural Biotechnology: meeting the needs of the poor?'. The report claimed that "agricultural biotechnology has real potential as a new tool in the war on hunger". In response to the report, more than 650 organisations from around the world signed an open letter in which they said "FAO has broken its commitment to civil society and peasants' organisations". The letter complained that organisations representing the interests of farmers had not been consulted, that FAO was siding with the biotechnology industry and, consequently, that the report "raises serious questions about the independence and intellectual integrity of an important United Nations agency". The Director General of FAO responded immediately, stating that decisions on biotechnology must "be taken at the international level by competent bodies" (in other words, not by non-government organisations). He acknowledged, however, that "biotechnology research is essentially driven by the world's top ten transnational corporations" and "the private sector protects its results with patents in order to earn from its investment and it concentrates on products that have no relevance to food in developing countries". In May 2006, a British newspaper published the resignation letter of Louise Fresco, the Assistant Director General of FAO. In her letter, the widely respected Dr Fresco stated that "the Organization has been unable to adapt to a new era", that "our contribution and reputation have declined steadily" and "its leadership has not proposed bold options to overcome this crisis". October 2006 saw delegates from 120 countries arrive in Rome for the 32nd Session of FAO's Committee on World Food Security. The event was widely criticized by Non- Government Organizations, but largely ignored by the mainstream media. Oxfam called for an end to the talk-fests while Via Campesina issued a statement that criticized FAO's policy of Food Security. Food marketing brings together the producer and the consumer. It is the chain of activities that brings food from "farm gate to plate." The marketing of even a single food product can be a complicated process involving many producers and companies. For example, fifty-six companies are involved in making one can of chicken noodle soup. These businesses include not only chicken and vegetable processors but also the companies that transport the ingredients and those who print labels and manufacture cans. The food marketing system is the largest direct and indirect non-government employer in the United States. In the pre-modern era, the sale of surplus food took place once a week when farmers took their wares on market day, into the local village market place. Here food was sold to grocers for sale in their local shops for purchase by local consumers. With the onset of industrialization, and the development of the food processing industry, a wider range of food could be sold and distributed in distant locations. Typically early grocery shops would be counter-based shops, in which purchasers told the shop-keeper what they wanted, so that the shop-keeper could get it for them. In the 20th century supermarkets were born. Supermarkets brought with them a self service approach to shopping using shopping carts, and were able to offer quality food at lower cost through economies of scale and reduced staffing costs. In the latter part of the 20th century, this has been further revolutionized by the development of vast warehouse-sized outof-town supermarkets, selling a wide range of food from around the world. Unlike food processors, food retailing is a two-tier market in which a small number of very large companies control a large proportion of supermarkets. The supermarket giants wield great purchasing power over farmers and processors, and strong influence over consumers. Nevertheless, less than ten percent of consumer spending on food goes to farmers, with larger percentages going to advertising, transportation, and intermediate corporations. Food deprivation leads to malnutrition and ultimately starvation. This is often connected with famine, which involves the absence of food in entire communities. This can have a devastating and widespread effect on human health and mortality. Rationing is sometimes used to distribute food in times of shortage, most notably during times of war. Starvation is a significant international problem. Approximately 815 million people are undernourished, and over 16,000 children die per day from hunger-related causes. Food deprivation is regarded as a deficit need in Maslow's hierarchy of needs and is measured using famine scales. Food aid can benefit people suffering from a shortage of food. It can be used to improve peoples' lives in the short term, so that a society can increase its standard of living to the point that food aid is no longer required. Conversely, badly managed food aid can create problems by disrupting local markets, depressing crop prices, and discouraging food production. Sometimes a cycle of food aid dependence can develop. Its provision, or threatened withdrawal, is sometimes used as a political tool to influence the policies of the destination country, a strategy known as food politics. Sometimes, food aid provisions will require certain types of food be purchased from certain sellers, and food aid can be misused to enhance the markets of donor countries. International efforts to distribute food to the neediest countries are often co-ordinated by the World Food Programme. Foodborne illness, commonly called "food poisoning," is caused by bacteria, toxins, viruses, parasites, and prions. Roughly 7 million people die of food poisoning each year, with about 10 times as many suffering from a non-fatal version. The two most common factors leading to cases of bacterial foodborne illness are cross-contamination of ready-to-eat food from other uncooked foods and improper temperature control. Less commonly, acute adverse reactions can also occur if chemical contamination of food occurs, for example from improper storage, or use of non-food grade soaps and disinfectants. Food can also be adulterated by a very wide range of articles (known as 'foreign bodies') during farming, manufacture, cooking, packaging, distribution or sale. These foreign bodies can include pests or their droppings, hairs, cigarette butts, wood chips, and all manner of other contaminants. It is possible for certain types of food to become contaminated if stored or presented in an unsafe container, such as a ceramic pot with lead-based glaze. Food poisoning has been recognized as a disease of man since as early as Hippocrates. The sale of rancid, contaminated or adulterated food was commonplace until introduction of hygiene, refrigeration, and vermin controls in the 19th century. Discovery of techniques for killing bacteria using heat and other microbiological studies by scientists such as Louis Pasteur contributed to the modern sanitation standards that are ubiquitous in developed nations today. This was further underpinned by the work of Justus von Liebig, which led to the development of modern food storage and food preservation methods. In more recent years, a greater understanding of the causes of food-borne illnesses has led to the development of more systematic approaches such as the Hazard Analysis and Critical Control Points (HACCP), which can identify and eliminate many risks. Some people have allergies or sensitivities to foods which are not problematic to most people. This occurs when a person's immune system mistakes a certain food protein for a harmful foreign agent and attacks it. About 2% of adults and 8% of children have a food allergy. The amount of the food substance required to provoke a reaction in a particularly susceptible individual can be quite small. In some instances, traces of food in the air, too minute to be perceived through smell, have been known to provoke lethal reactions in extremely sensitive individuals. Common food allergens are gluten, corn, shellfish (mollusks), peanuts, and soy. Allergens frequently produce symptoms such as diarrhea, rashes, bloating, vomiting, and regurgitation. The digestive complaints usually develop within half an hour of ingesting the allergen. Rarely, food allergies can lead to a medical emergency, such as anaphylactic shock, hypotension (low blood pressure), and loss of consciousness. An allergen associated with this type of reaction is peanut, although latex products can induce similar reactions. Initial treatment is with epinephrine (adrenaline), often carried by known patients in the form of an Epi-pen. Dietary habits are the habitual decisions a person or culture makes when choosing what foods to eat. Although humans are omnivores, many cultures hold some food preferences and some food taboos. Dietary choices can also define cultures and play a role in religion. For example, only kosher foods are permitted by Judaism, and halal/haram foods by Islam, in the diet of believers. In addition, the dietary choices of different countries or regions have different characteristics. This is highly related to a culture's cuisine. Dietary habits play a significant role in the health and mortality of all humans. Imbalances between the consumed fuels and expended energy results in either starvation or excessive reserves of adipose tissue, known as body fat. Poor intake of various vitamins and minerals can lead to diseases which can have far-reaching effects on health. For instance, 30% of the world's population either has, or is at risk for developing, Iodine deficiency. It is estimated that at least 3 million children are blind due to vitamin A deficiency. Vitamin C deficiency results in scurvy. Calcium, Vitamin D and phosphorus are inter-related; the consumption of each may affect the absorption of the others. Kwashiorkor and marasmus are childhood disorders caused by lack of dietary protein. Many individuals limit what foods they eat for reasons of morality, or other habit. For instance vegetarians choose to forgo food from animal sources to varying degrees. Others choose a healthier diet, avoiding sugars or animal fats and increasing consumption of dietary fiber and antioxidants. Obesity, a serious problem in the western world, leads to higher chances of developing heart disease, diabetes, and many other diseases. More recently, dietary habits have been influenced by the concerns that some people have about possible impacts on health or the environment from genetically modified food. Further concerns about the impact of industrial farming on animal welfare, human health and the environment are also having an effect on contemporary human dietary habits. This has led to the emergence of a counterculture with a preference for organic and local food. Between the extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as scurvy, obesity or osteoporosis, as well as psychological and behavioral problems. The science of nutrition attempts to understand how and why specific dietary aspects influence health. Nutrients in food are grouped into several categories. Macronutrients means fat, protein, and carbohydrates. Micronutrients are the minerals and vitamins. Additionally food contains water and dietary fiber. Some countries list a legal definition of food. These countries list food as any item that is to be processed, partially processed or unprocessed for consumption. The listing of items included as foodstuffs include any substance, intended to be, or reasonably expected to be, ingested by humans. In addition to these foodstuffs drink, chewing gum, water or other items processed into said food items are part of the legal definition of food. Items not included in the legal definition of food include animal feed, live animals unless being prepared for sale in a market, plants prior to harvesting, medicinal products, cosmetics, tobacco and tobacco products, narcotic or psychotropic substances, and residues and contaminants. Enzymes are biochemical catalysts used in converting processes from one substance to another. They are also involved in reducing the amount of time and energy required to complete a chemical process. Many aspects of the food industry use catalysts, including baking, brewing, dairy, and fruit juices, to make cheese, beer, and bread. Dried fruits make tasty snacks and are very handy for taking on camping or hiking trips. Dried fruits can also be chopped up and used dry with breakfast cereal, granola, or cookies. Fruit can be reconstituted for use in recipes by pouring just enough boiling water over it to cover and simmering it for 15 minutes. Or pour cool water over it to cover, then soak for a few hours. Soak only until the fruit is plump because soaking too long makes the fruit mushy and less flavorful. To retain nutrients, cook the fruit in the same water used for soaking. Most dried fruit needs no extra sugar because some of the starch in the fruit turns to sugar during the drying process. If you wish to sweeten the fruit, do so after cooking; otherwise the fruit will become mushy. Reconstituted fruit is especially good in cakes, pies, and other desserts. If the recipe calls for water, use the water in which the fruit was soaked. When you reconstitute pieces of vegetables, they should become nearly the same size they were when fresh. Add 1 to 2 cups of water to 1 cup of dried vegetables. Add more water later if necessary. Blanched dried vegetables should be soaked about 2 hours before cooking. Unblanched vegetables will take longer. Dried beans and peas can be soaked overnight or boiled 2 minutes and then soaked 1 hour before cooking. Dried vegetables taste best if used in soups, stews, or other dishes cooked with liquid and seasonings. The seasonings help to enhance the natural flavor of the vegetables. To become a successful, creative cook, start using some of the fine herbs such as sweet basil, marjoram, or summer savory. But be miserly in your measure; herbs can easily overpower the flavor of the food they are used to season. You can make your own favorite blend of herbs for a variety of uses. A combination of marjoram, oregano, basil, and thyme used in equal parts is a good basic blend for soups, stews, sauces, casseroles, and salads. Sage, savory, and rosemary may be added to the blend for use with poultry, Italian dishes, or other spicy foods. You can adjust the amounts to suit your taste. You do not need to reconstitute herbs before you use them. To substitute dried herbs for fresh herbs, use 1/4 teaspoon of dried herbs for 1 teaspoon of fresh More and more people live in the cities and are far away from the production areas of food. In many families both husband and wife are working and therefore there is little time for the preparation of food based on fresh ingredients. The food industry offers products that fulfill many different needs: From peeled potatoes that only have to be boiled at home to fully prepared ready meals that can be heated up in the microwave oven within a few minutes. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks. In addition, it increases seasonal availability of many foods, enables transportation of delicate perishable foods across long distances. Modern food processing also improves the quality of life for allergists and other people who cannot consume some common food elements. Food processing can also add extra nutrients such as vitamins Processed foods are often less susceptible to early spoilage than fresh foods, and are better suited for long distance transportation from the source to the consumer .Fresh materials, such as raw meats, are more likely to harbour pathogenic micro-organisms (e.g. Salmonella) capable of causing serious illnesses. Water may not seem like a nutrient, but it is, and probably our most important one. Humans can live several weeks without food but only a few days without water. Water makes up almost two- thirds of the body. It is part of every cell. Water carries all of the other nutrients to the cells and takes wastes away. It also helps regulate body temperature. Every food has some water in it. Scientists knew there was something else in food besides water, carbohydrates, protein, and fat long before they could isolate the mystery ingredient in the laboratory. The mystery remained unsolved until 1913 when the unknown ingredient was finally discovered. As it turned out, it wasn't just one ingredient but several similar chemicals that we now call vitamins. Although each has a scientific name, we know them best by their letter names A,B,C,D,E, and K. (There are eight different B vitamins and some other vitamins such as niacin that don't have letter names.) Vitamins probably eluded scientists for so long because foods contain such tiny amounts of them. Nevertheless, without even these tiny amounts, the cells couldn't do their jobs. Vitamins are responsible for helping to form the material that holds cells together, for helping bones and teeth to use calcium, for helping the body use energy, and for many other critical life-support activities. Vitamins are nutrients required in small amounts for essential metabolic reactions in the body. An adequate supply of vitamins can prevent such diseases as beriberi, anemia, and scurvy while an overdose of vitamins can produce nausea and vomiting or even death. Dietary minerals in foods are large and diverse with many required to function while other trace elements can be hazardous if consumed in excessive amounts. Food coloring is added to change the color of any food substance. It can be used to simulate the natural color of a product as perceived by the customer, such as red dye like FD&C Red No.40 to ketchup or to add unnatural colors to a product. Caramel is a natural food dye; the industrial form, caramel coloring, is the most widely-used food coloring and is found in foods from soft drinks to soy sauce, bread, and pickles. Flavor in food is important in how food smells and tastes to the consumer. Some of these products occur naturally like salt and sugar. Artificial flavors include methyl salicylate which creates the wintergreen odor and lactic acid which gives milk a tart taste. Food additives are substances added to food for preserving flavors, or improving taste or appearance. These processes are as old as adding vinegar for pickling or as an emulsifier for emulsion mixtures like mayonnaise. These are generally listed by "E number" in the European Union or GRAS ("Generally recognized as safe") by the United States Food and Drug Administration. It would be impossible to feed the populations of large cities of the world if there were no industries capable of taking in bulk food from the farms and of preserving and processing it for distribution through wholesale and retail outlets. In all the technically developed countries the food industries employ chemists and nutritionists to see that nutritive value of the raw food is retained as much as possible. In general, canned and frozen foods purchased in a supermarket may be of higher nutritive value than corresponding “fresh” foods in an open small-town market: the latter may have been on sale many days after harvesting. It would also be impossible to preserve and maintain the flavour of foods for the feeding of large populations without the addition, during processing, of chemicals which act as preservatives, emulsifiers, flour improvers, sweeteners, and flavouring agents. People in large cities may ingest small amounts daily of 100 such food additives, all of which could be potentionally poisonous. The addition of vitamins, minerals, or amino acids can increase the nutritive value of foods. Margarines are enriched with vitamins A and D and, in general have a nutritive value similar to that of good quality butter. Many infant foods are enriched with vitamin D and other nutrients. Most nutritionists agree that in certain circumstances enrichment is beneficial, for example, in the manufacture of margarines. There is, however, considerable disagreement about the value of widespread enrichment. FERMENTATION AND PICKLING Although microorganisms are usually thought of as causing spoilage, they are capable under certain conditions of producing desirable effects, including oxidative-alcoholic fermentation. The microorganisms that grow in a food product, and the changes they produce, are determined by acidity, available carbohydrates, oxygen and temperature. Untreated meat, for example, molds and putrifies. The addition of brine or salt causes different organisms to grow. An important food preservation method combines salting to control microorganisms selectively and fermentation to stabilize the treated tissues. The process for cucumbers is called pickling and is also applied to many other food commodities. Fresh fruits and vegetables soften under 24 hours in a watery solution and begin a slow, mixed fermentation-put-refaction. The addition of salt suppresses undesirable microbial activity, creating a favourable environment for the desired fermentation. Most green vegetables and fruits may be preserved by pickling. Sauerkraut is made by bacterial fermentation of cabbage controlled by the use of salt. The acid that develops during fermentation acts as a preservative and develops the flavour. Fermented foods and pickled products require protection against molds, metabolize the acid developed and allow the advance of other microorganisms. Fermented and pickled food products placed in cool storage can be expected to remain stable for several months. Longer storage periods demand more complete protection, such as canning. Nutrient retention in fermented and pickled products is about equal to retention for products preserved by other methods. Carbohydrates usually undergo conversion to acid or to alcohol, but these are also of nutritive value. In some instances, nutrient levels are increased because of the presence of yeasts. A History of Soul Food Every ethnic group has what it calls "soul food" - soothing, comfort food that brings back warm memories of family dinners. Today, in America, the term "soul food" simply means African-American cuisine. To fully understand the concept of "soul food," you must learn the traditional foods of Africa. Many common American foods are indigenous to Africa. Grains, legumes, yams, sorghum, watermelon, pumpkin, okra, and leafy greens could be found as early as 4000 BC on the African continent. Eggplant, cucumber, onion and garlic are believed to be African in origin, while only a small number of fruits are grown on the continent: wild lemons, oranges, dates and figs. Many culinary historians believe that in the beginning of the 14th century, around the time of early African exploration, European explorers brought their own food supplies and introduced them into the African diet. Foods such as turnips from Morocco and cabbage from Spain would play an important part in the history of African American cuisine. As meat was used sparingly, the average African ate mostly a vegetarian diet, though seafood showed up often in stews served with a starch. Okra and native peppers were used as seasoning and salt as a preservative. Research scientist William Bascom found that a large portion of tribal Africans shared basic cooking techniques. Simplicity was the trademark in African cooking. Utensils for cooking and eating were made from earthenware or prepared gourds or other squashes. Africans cooked in boiling water and steamed food using leaves as a steamer. They often fried foods in palm oil or vegetable butters, toasted and roasted using fire and baked in ashes. Some ingredients were smoked for flavoring and others thickened with nuts and seeds. Africans also made rice dishes and created fritters. A common African meal consisted of rice, chicken and milk while the poorest Africans ate a type of couscous with leafy vegetables. This made the African diet healthy and satisfying. The tradition of communal living with shared meals was the perfect environment for conversation and the reciting of oral history and storytelling. When slave trading began in the early 1400s, the diet of newly enslaved Africans changed on the long journeys from their homeland. On these terrible voyages across the Atlantic Ocean, small portions of rice and beans, with the occasional vegetable or piece of fruit, replaced their normally healthy diet. A "slabber" sauce, made from old beef and rotten fish and salt, was poured over the rice and beans in an attempt to fill the slave's stomachs. It was during this time that surprisingly some of the indigenous crops of Africa began showing up in the slaves new home in the Americas. Tall tales of seeds from watermelons, okras and sesame being transported in the slave's ears, hair or clothing could be true. The more likely idea would be that the European slave traders, urged by the African slave traders themselves, brought the food over for trade. Whatever the case, these familiar foods would soon become part of America's southern crops. African slaves actually had a better diet than their owners did. The owners ate mostly fatty foods, with little or no vegetables and lots of sweets and alcohol that left them lethargic. The slaves needed to be strong and energetic to work the fields, so large vegetarian meals were encouraged and drinking discouraged. Ice tea and lemonade became typical drinks. As the Africans began to assimilate into the American slave society, they "made do" with the ingredients at hand. The fresh vegetables found in Africa were replaced by the throwaway foods from the plantation house. Their vegetables were the tops of turnips and beets and dandelions. Soon they were cooking with new types of greens: collards, kale, cress, mustard and pokeweed. With a lot of lard for flavor from the slaughtered hog and cracklin' from it's skin, they made a filling meal. Weekly rations were given out from the smokehouse of corn meal, a few pounds of meat and black molasses. The women would use these ingredients, with onions, garlic, thyme and bay leaf, to create a variety of dishes. The cornmeal was turned into a bread. The meat (pig's feet, ham hocks, chitterlings, pig ears, hog jowl, tripe, and crackling) became the main dish with generous portions of greens, and the molasses and cornmeal would be mixed to become a dessert. The slave diet began to evolve when slaves entered the plantation houses as cooks. With an array of new ingredients at their fingertips and a well-tuned African palate, the cooks would make delectable foods for their masters. Suddenly southern cooking took on new meaning. Fried chicken began to appear on the tables, sweet potatoes (which had replaced the African yam) sat next to the boiled white potato. Regional foods like apples, peaches and berries, nuts and grains, soon became puddings and pies. Possum was the meat of choice among slaves since hunting was done during the only free hours a slave had, after all the work for their master was complete, in the wee hours of the night. Soon the slave's cuisine became knows as "good times" food. After long hours working in the fields or up at the house, the evening meal was a time for families to get together. The big pots became a meal for both body and soul. It was during the meal that the oral history was re-told, forbidden religious ceremonies held and family and friends visited. Some slaves tried to escape from captivity and Native Americans took in many. From the Native Americans they learned to use the ground green sassafras leaves as a new spice. Sadly, many escaped slaves were re-captured and returned to their plantations. No doubt the ground sassafras went with them and was called "file'" by Lousiana slaves. Because each state had its own cultural influences, the African dishes began to take on the qualities from that region. Rich and saucy dishes with a French accent came from Louisiana, while the Carolina's Spanish culture introduced dishes like jambalaya and a strange food called sausage into the cooking pots that sat over open fires in the slave's quarters. It could be surmised that from a bouillabaisse or a cassoulet found in the French cuisine, the slaves changed it into a gumbo using the shellfish from the bayou and the okra and file' to make a dish more to the liking of African taste bud. Unlike the dishes from other countries with names that usually told what the ingredients were, black cuisine had names that did not necessarily give you a clue to the ingredients, but did tell you a little history of how it came about. It is said that the hushpuppy got its name from the dredging of the catfish that would have been thrown out. Being thrifty, the cook from the house would send this down to the slave quarters and the women added a little milk, egg and onion and fried it up. It is said they were tossed at the dogs to keep them quiet while the food was being transferred from the pot to the table, i.e., "hush puppy! hush puppy!." Hoecakes are a dish said to have been a corn bread batter that was heaped onto the spade or hoe which was held over the open fire to make a quick bread. Ashcakes are a corn meal mixture baked in an open fire, and the baked bread is washed after cooking then served. A "gut strut" is another name for a big pot of chittlin's. No matter the stories, good, black cuisine was wholesome food that used everything available. Nothing was ever wasted in the black kitchen. Leftover fish became croquettes (by adding an egg, cornmeal or flour, seasonings and breaded then deep-fried). Stale bread became bread pudding, and each part of the pig had its own special dish. Even the liquid from the boiled vegetables was turned into "pot likker" which was used as a type of gravy or as a drink in and of itself. While the master would have an apple, peach or cherry baked pie, slaves were ingenious and produced fried pies that could be tucked into a pocket for a sweet pick-me-up in the fields. When the emancipation came in 1863, slaves soon scattered from the confines of the plantation into other parts of the United States. Black cowboys could be found in Texas, domestics in Illinois and Michigan, porters worked the railroad stations up and down the eastern seaboard. As the railroad tracks expanded across the middle of the country, black cooks could be found working in train kitchens too. Wealthy and middle class whites and blacks in large cities hired black cooks. This brought southern black cuisine into the homes of many Americans. So as not to lose contact with family members scattered far and wide, Sunday dinners became a common time for families to get together. It was common for a son or daughter to travel some distance just for a good home cooked meal. Aunts, uncles, cousins (both real and pretend) would converge, not to the largest home, but to the house with the best cook for a meal. Occasionally there would be a potluck where everyone brought their "best" dish, but the normal pattern was for the women to get in the kitchen and cook up a storm. Men seldom took part, unless there was ‘cueing (barbecue). In the mid 1960s, when the Civil Rights Movement was just beginning, terms like "soul man" "soulful" and just "soul" were used in connection with blacks themselves. It caught on with mainstream America and someone coined the term "soul food" for black cuisine and it stuck. Today when most people think of soul food, it is a table heavy with trays of watermelon, ribs, candied sweet potatoes or yams, greens and fried chicken. Each black family, however, has its own idea of what black cuisine is. Hogshead cheese sliced on saltine crackers with hot sauce and beer is one such dish. Crab cakes. Carrot and Raisin salad. Fried corn. Hush puppies. Corn pone. Red beans and rice. Greens. Liver and onions. Lima beans with ham hocks. Stewed okra and tomatoes. Cornbread dipped in buttermilk. Fried catfish. Smothered chicken. Pickled pig's feet. Fried cabbage. Neckbones. Tongue. Chittlin's. Tripe. Gumbo. Breaded fried pork chops with a mess of greens. Black-eyed peas...and, grits. Although grits is truly a southern dish, it is considered here as a part of black cuisine because black Americans eat grits for breakfast, lunch or dinner; plain, with butter, with gravy, with cheese or deep-fried. Black owned restaurants have begun to stray from the traditional foods for health reasons. They sometimes substitute canola oil for lard, chicken for pork; oven fried chicken for deep fried and simple fresh fruit for the sweet cobblers and bread puddings they grew up on. The aroma of "soul food" can fill the house and let the neighbors know that a big pot is cooking. Today, many are just too busy to spend hours in the kitchen cooking up the traditional foods of black America. In the search for the best soul food restaurant, there is one piece of advice: If you walk by and the aroma does not greet you at the door, keep walking. Cuisine of the South The cuisine of the south is largely non-greasy, either boiled or steamed and therefore very light on the stomach. Rice is the staple of the south Indian meal. Traditionally south Indian food is served on a banana leaf and each dish has its own specific place on the platter and has to be served in a particular order. The meal consists of several courses of rice, which is eaten with a different dish like sambar, rasam and curd during each course. There are several accompaniments like curries, made of either vegetables or meat, vegetable stews, raitha, papad and pickles. Curd is usually a must for all vegetarian meals. Coconut is used liberally both as garnish and also as part of the masala. South Indian snacks are most popular all over the country. The ubiquitous idli, dosa and vada, are eaten with sambar by the bowlsful and spicy coconut chutney. While idli is steamed rice cakes, dosa is a pancake and vada are deep fried dal doughnuts. The influence of the Mughal rulers who ruled India is perhaps most felt in their food. A major contribution towards this is the tandoor which is an earthen oven, used to make rotis and kababs, which are pieces of meat marinated in spices and skewered over a coal tandoor. Some of the famous Mughlai dishes include tandoori chicken, seekh and boti kabab and even tandoori fish. Mughlai food is very rich, its sauces consisting of curd, cream and crushed nuts like cashew. The biryani from the kitchens of the nawabs of Hyderabad, is a flavoured and spiced rice cooked with ghee and chicken or meat, and is a meal-in-a-dish eaten with raitha and salad. Aromatic spices and ghee make Mughlai food a very rich form of cuisine. Gujarat has a wide variety of savoury food, pickles and sweets. Roti itself is prepared in a number of variations from the petal soft phulkas to the bone dry khakra, which is a spiced, crunchy preparation usually taken on journeys. The population which is predominantly Jain doesn't include spices like onion and garlic and yet, the food is so interesting and delicious, which goes to prove the culinary skills of the people of Gujarat. The Gujaratis have a sweet tooth and this shows in their cooking. Every dish is sweetened, be it a vegetable preparation or the simple dal, even pickles and chutneys are flavoured with jaggery and sugar. Seasoning of food is given great importance with mustard, fenugreek, thyme and asafoetida used both for flavour and as digestive aids. The staple diet of the Bengalis is rice and fish. A true Bengali will consider a meal incomplete without fish and celebrations are never done without a fish preparation. Mustard oil is the medium of cooking as it imparts a unique flavour and taste especially to the fish items. Fish is cooked in a variety of ways -steamed, fried and boiled with various spices for different flavours. Mention Bengal and one is immediately reminded of the delicious sweets of the state — gulab jamun, rasagulla, sandesh, cham cham and many more. If Gujarat has a profusion of savoury items, Bengal matches it with its sweets. Made of milk and cottage cheese, these are light and delectable. Coming to the food, the staple diet of the people of Bengal and Orissa includes rice and fish, especially fresh water fish. Even Brahmins of Bengal eat fish and no celebration is complete without it. The principal medium of cooking is mustard oil. A distinct flavour is imparted to the fish dishes by frying them in mustard oil before cooking them in gravy. Fish is also steamed by the Bengalis. Bengalis have a special seasoning called 'Panchphoran' which includes five spices — mustard, aniseed, fenugreek seed, cumin seed and black cumin seed. The garam masala is made up of cloves, cinnamon, cumin and coriander seeds, mace, nutmeg, and big and small cardamoms. Punjabi food is wholesome and full of rustic flavour. The custom of cooking in community ovens or tandoors, prevails in rural pockets till today. Tandoori dishes are popular all over the country today. Nans and parathas, rotis made of cornflour (makke di roti) are typical Punjabi breads. The cuisine is characterised by a profusion of dairy products in the form of malai (cream), paneer (cottage cheese) and curds. The dals are a speciality of this type of cuisine. Made of whole pulses like black gram, green gram and Bengal gram, they are cooked on slow fire, often simmered for hours till they turn creamy and then flavoured with spices and rounded off with malai for that rich finish. Rajma (Kidney beans) and rice is a favourite as are makke di roti and sarson ka saag (cornflour rotis and a creamy preparation made of mustard greens). Eaten with plenty of ghee, this is a winter favourite with Punjabis. The basic gravy used for vegetables and meat dishes is onion-tomato-garlic-ginger. Though chicken is a favourite with non-vegetarians, fish is also a delicacy, especially in the Amritsar region, which is also known for its kulcha, a baked bread made of refined flour. Tall glasses of lassi, made of yoghurt, added with either salt or sugar is a popular cooling drink not only in Punjab but all over the country. Phirni, a sweet dish made of milk, rice flour and sugar and chilled in earthenware bowls is a typical Punjabi dessert. Traditional Kashmiri cooking is called Wazhawan and comprises mostly of nonvegetarian dishes. It is rich and aromatic with a wonderful flavour unique to Kashmiri cuisine. Most Kashmiris including the Brahmins (Kashmiri Pandits) are meat eaters. The cuisine of the state is characterised by three different styles of cooking — the Kashmiri Pandit, the Muslims and the Rajput styles. Though they eat meat, surprisingly, many traditional Kashmiri Pandits don't include garlic and onion to their cooking. One of the distinct features of Kashmiri cuisine is the generous use of curds in the gravies, giving the dishes a creamy consistency. The Kashmiris also use asafoetida to flavour their meat dishes. Saunf (aniseed) and dry ginger are other spices used imaginatively to enhance the taste. For instance some dishes get their pungency not from chillies, but from dry ginger. Other dishes have no spice except may be a little saunf added to them for flavour. Being the home of saffron, the colourful flavouring agent is used in the pulaos and sweets. Walnuts, almonds and raisins are also added to the curries. Ghee is the medium of cooking, probably because the fat is required to impart heat to the body, though mustard oil is also used. Some of the better known dishes are yakhni, tabaq naat, which is an exotic dish made of fried ribs and decorated with silver varq, dum aloo, rogan josh, gaustaba which is a light meatball, haleem which is meat pounded with wheat, etc. The cuisine of Andhra Pradesh is reputedly the spiciest and hottest of all Indian cuisine. The cuisine includes both the original Andhra cooking and the Hyderabadi cuisine with its Mughlai influence. It is the former which is red hot. The pickles and chutneys are very popular and last for several years. Chutney is made of practically every vegetable including tomatoes, brinjals and an aromatic green called 'gonkura' which is an Andhra speciality. The mango pickle 'Avakkaya' is a perennial favourite of Andhraites all over the world. The vegetables and greens are prepared with various different masalas giving the same vegetable different flavours. Traditional Andhra cuisine also has many non-vegetarian dishes which are also spicy and unique in taste. Hyderabadi cuisine is rich and aromatic with a liberal use of exotic spices and ghee, not to speak of nuts and dry fruits. Lamb is the most widely used meat in the non-vegetarian dishes. The biryanis (flavoured rice with meat or vegetables) is one of the most distinct Hyderabadi food. Cauliflower mixed vegetables Cauliflower is typically fried or cooked in a fair amount of oil, but I add the oil at the end, to bring a similar flavor with a fraction of the fat. 1 small cauliflower (3 cups), divided into small florets (1- inch) 11/2 cups carrots, peeled and thinly sliced (1/4-inch) 11/2 cups zucchini, thinly sliced (1/4-inch) 4 tsp vegetable oil a pinch of asafetida 1/2 tsp cumin seeds 1 tsp fresh ginger, chopped 1/4 tsp turmeric 11/2 tsp salt 1/2 tsp cayenne pepper (optional) 1 tbsp coriander powder 1/2 tsp mango powder 3/4 tsp garam masala 1 tbsp fresh coriander, finely chopped (cilantro) Wash and drain cauliflower, carrots and zucchini. Set aside. Heat 1 tsp oil in a heavy, nonstick skillet over medium high heat. Add asafetida and cumin seeds and cook for a few seconds until seeds are golden brown. Add vegetables and stir. Add ginger, turmeric, salt and cayenne pepper. Stir thoroughly. Heat through, cover with a lid and reduce heat. Simmer for 8–10 minutes. Open 1–2 times to stir the vegetables. Cook until vegetables are tender but firm. Sprinkle with coriander powder, mango powder and garam masala. Stir carefully in a lifting and turning fashion so as not to mash the vegetables. Add the remaining 3 teaspoons of oil around the sides of the pan, allowing the oil to get to the bottom of the pan. All the liquid from the vegetables should be evaporated; if not, increase heat to evaporate it. Fry for 3–5 minutes, stirring once or twice in the same lifting and turning fashion. (This final roasting or frying in the oil brings out the true flavor of this dish.) Transfer to a serving platter. Garnish with fresh coriander.

It can be made in a tandoor (clay oven), baked in an oven or grilled on a barbecue. 3 lb chicken pieces 1 small onion 1/2 cup tomato sauce 1/2 cup nonfat plain yogurt 1 tsp fresh ginger, chopped 2 garlic cloves 2 tsp coriander powder 1/2 tsp cayenne pepper (optional) 2 whole cloves 1 tsp cumin seeds 4 cardamom pods 1 tsp salt 1 tsp garam masala 1/4 tsp red food coloring Remove the skin and all visible fat from the chicken pieces. (I often have the butcher skin the chicken.) Cut 2–3 slits, 1 inch long and 1/2 inch deep, in each piece of chicken. Place in a casserole dish and set aside. Cut onion into 4–6 pieces. In a blender jar put onion, tomato sauce, yogurt, ginger, garlic cloves, coriander powder, cayenne pepper, cloves, cumin seeds, cardamom pods, salt, garam masala and red food coloring. Blend to a smooth paste. Pour the tandoori paste on the chicken and turn pieces to thoroughly coat with spices. Cover with a lid or plastic wrap and marinate in the refrigerator 4–24 hours. Preheat the oven to 400° F. Remove chicken pieces from the marinade, saving marinade. Arrange pieces in a broiler pan. Bake uncovered in the middle of the oven for 30 minutes. Turn pieces over and brush with remaining marinade. Bake for 10–15 minutes until chicken is tender. Turn oven to broil. Turn pieces over once again and broil for 5 minutes to get a nice red color. Transfer to a serving platter. Serve with lemon wedges or squeeze lemon juice over the chicken before eating, if desired.

Each black family, however, has its own idea of what black cuisine is. Hogshead cheese sliced on saltine crackers with hot sauce and beer is one such dish. Crab cakes. Carrot and Raisin salad. Fried corn. Hush puppies. Corn pone. Red beans and rice. Greens. Liver and onions. Lima beans with ham hocks. Stewed okra and tomatoes. Cornbread dipped in buttermilk. Fried catfish. Smothered chicken. Pickled pig's feet. Fried cabbage. Neckbones. Tongue. Chittlin's. Tripe. Gumbo. Breaded fried pork chops with a mess of greens. Black-eyed peas...and, grits. Although grits is truly a southern dish, it is considered here as a part of black cuisine because black Americans eat grits for breakfast, lunch or dinner; plain, with butter, with gravy, with cheese or deepfried. Black owned restaurants have begun to stray from the traditional foods for health reasons. They sometimes substitute canola oil for lard, chicken for pork; oven fried chicken for deep fried and simple fresh fruit for the sweet cobblers and bread puddings they grew up on. The aroma of "soul food" can fill the house and let the neighbors know that a big pot is cooking. Today, many are just too busy to spend hours in the kitchen cooking up the traditional foods of black America. In the search for the best soul food restaurant, there is one piece of advice: If you walk by and the aroma does not greet you at the door, keep walking. CHEWING GUM This is a kind of confection that contains gum base, a masticatory material that does not dissolve in saliva when the gum is chewed. American gum averages in content 20% gum base, 16% corn syrup, 63% sugar, and less than 1% flavoring, such as mint, fruit and spice. Progressively more and more domestic ingredients such as resins and waxes are replacing the imported products. Calcium carbonate, which is a component of most base formulas, neutralizes traces of acid forming on the teeth from fermented food residues and so tends to reduce dental caries. Whatever ingredients are used in a gum base, they are blended together hot. The melted gum base is cleaned and mixed with syrup and flavor; the resulting chewing gum is shaped by extrusion and rolling. Additional powdered sugar is used on the surface to prevent adhesion to wrappers. A hard sugar coating can be built up on shaped pieces of gum in a tumbling pan by alternate wetting with a sugar solution and evaporating the added water in a dry air blast. CONFECTIONS About 70 farm products of varying carbohydrate content furnish more than 90 percent of all the raw materials for the over 2000 varieties of confections.Common sweeteners used in confections are refined crystalline cane sugsr, brown sugar, liquid sugar, corn syrup, starch, molasses, honey and maple sugar. More emphasis is being placed on the addition of vegetable and animal proteins in confections, such as soya proteins, yeast, gelatin and pulverized dried beef. The most important physical and chemical properties are relative sweetness, solubility and crystallization characteristics, density of liquid sweeteners and moisture content of solid sweeteners, hydroscopicity, flavor, fermentation and preservative properties, molecular weight and freezing-point depression. Proteins and fats also vary considerably with respect to the above properties. Requirements also vary widely, according to the qualities desired in the particular type of confection. The large variety of products turned out by the confectionery industry require a remarcable flexibility from the carbohydrates which serve major constituents of these products. Confections are divided into three categories: hard candies or high-boiled sweets, chewy confections and aerated confections. The second and third categories are further subdivided into two classes, where the sugar solution is supersaturated(grained) or unsaturated(nongrained). Candies that grain are of crystalline structure. The non-grained candy group consists of taffies and chewy candies. There are many intermediate types of confections combining the characteristics of both the grained and non-grained candies.Sugar is the universal graining agent. The regulators are corn syrup, invert sugar and others that retard or prevent sucrose crystallization. Part VII. APENDIX. Table 1 Recipes of bread.
