Costa Rican Fruits Annona spp. I. Taxonomy Annonaceae - 80 genera, 850 species. Native to tropical Am erica, being used by native Am ericans in pre-Colum bian tim es. Several Annona im portant com m ercially or locally; referred to as "custard apples". • • • • A. cherimola - Cherim oya (chirim oya, cherim olia, anona blanca). Highland species from the slopes of the Andes of Peru, Ecuador. The surface texture is patch-like, but sm oother than m ost others. A. squamosa - Sweetsop, sugar apple (anon, anona blanca). This is the m ost widely grown Annona. A. cherimola × A. squamosa - Atem oya, (atem oya, chirim oriñon). This hybrid is m ore like the cherim oya in eating quality (very good), but has a m ore tropical adaptation. A. muricata L. - soursop (guanabana). This is the largest fruited Annona, having fruits borne on m ain stem s (cauliflorous) up to 10 or 15 lbs. II. Description • • • • • • sm all to m edium size trees, spreading habit and an unusual 2-ranked phyllotaxy fairly large, green fruit with a custard or pudding-like texture when ripe; brown or black when ripe. Fruit is an aggregation of berries (syncarp), 50 or m ore per fruit, fused at m aturity. The surface of the fruits is distinctly lobed where each individual berry fits into the aggregate. Many large, brown/black seeds, which are m ildly poisonous. W ait until the fruit is very soft and brown/black before eating; you should be able to spoon the flesh out easily. Often m ade into drinks, ice cream , puddings. Fresh pulp is sweet, arom atic, with slightly astringent subflavor; often with grit cells. III. Food value, usage. • • • • • • • • W ater low for fresh fruit, 76%; Carbohydrates 18.2%; Fruits relatively high in Ca, P, and Fe. Juice of crushed seeds causes tem porary blindness; extracts are used as fish poisons and insecticides; seed resins of atem oya are used against lice in tropical Am erica. Tannins in bark and leaves of soursop m ay cause cancer. Cancer therapy drugs - apom orphine alkaloids are being studied for this purpose from soncoya. Snake-bite antidotes are m ade from root bark of A. nana (Angola). Toothache relief - is provided by a m outhwash of bark decoction of A. senegalensis (wild custard apple of western Africa). Infusions of bark, leaves, and roots are in “daily use” in folk m edicines for alleviating fevers and intestinal disorders. Superstitions - Cuba: Pond apple considered poisonous; actually just unpalatable. Ceylon: The custard apple is thought to cause leprosy. Central Am erica: Soncoya blam ed for causing chills and fevers. Costa Rican Fruits Avocado I. Taxonomy • • • Persea americana, Fam ily - Lauraceae (aguacate, cura, cupandra, palta) Native to tropical Am erica, grown pantropically and into subtropical areas, California Florida. 3 races: 1.W est Indian (Florida): P. americana Mill. var. americana. Large, oval to round, green fruit, sm ooth skin. 2.Guatem alan: P. nubigena var. guatemalensis. Skin granular or pebbled, som e purple in color. 3.Mexican: P. americana Mill. var. drymifolia. Usually thin, sm ooth skin, often purple or black in color; m ost cold tolerant, can grow at high elevation (5000 ft). Hybrids am ong races often the m ost com m ercially grown types III. Description: • • • • Plant: Tall, evergreen tree (30m ) of the rain or cloud forest. Flow ers: Sm all, pale-green or yellow borne in term inal panicles. Pollination: Cross-pollination necessary for full production. Fruit: Pear-shaped or rounded, 3-13 inches long, up to 6 inch diam eter. Skin yellow-green to dark purple, sm ooth or pebbled. Flesh yellowgreen in color, buttery/nut-like flavor; high in fat (5-20%). Large (.2 inch) single seed in center, ivory in color, surrounded by brown, papery seed coat. III. Food value, usage. • • • W ater 65% (low for fresh fruit), High calories 245. Unusually high in fat (up to 20% - m ost fresh fruits have <1% fat). Leaves, bark, fruit, and seeds poisonous to cattle, horses, rabbits, goats, fish. Toothache relief - piece of seed or a decoction of put into bad teeth. Costa Rican Fruits Banana and Plantain I. Taxonomy • Bananas and plantains belong to the fam ily Musaceae, genus Musa. • Bananas are derived from M. acuminata, plantains from M. balbisiana or hybrids between the 2 species. • Musa spp. originated in southeastern Asia, from India east and south to northern Australia. Bananas are now grown com m ercially in m ore countries than any other food crop (130). Costa Rica ranks 8 th am ong banana producers in the world. II. Description: • • • • Plant: Large, tree-like herbaceous m onocots, reaching 15-25 ft. The "trunk" is a pseudostem , the clustered, cylindrical aggregation of leaf stalk bases. Leaves are am ong the largest of all plants, becom ing up to 9 ft long and 2 ft wide; 5-15 leaves per plant. The perennial portion is the corm , giving rise to shoots and roots. Shoots are thinned to 2 per corm -a "parent" for fruiting and a "follower" to take the place of the parent after it fruits and dies back. A plant bears fruit 10-12 m onths after planting. Flow er: The inflorescence is a spike originating from the tip of the corm (rhizom e). Initially, it appears above the last leaves in an upright position, and consists only of a large, purple, tapered bud. As this bud opens, the slim , white, tubular, toothed flowers are revealed, clustered in whorled double rows along the stalk, each cluster covered by a thick, waxy, purple hood-like bract. Pollination: Not needed; fruit is set parthenocarpically. Fruit: an epigynous berry; fruit are borne in "hands" of up to .20 fruit, with 5-13 hands per spike. III. Food value, usage: • • • • • • • Contrary to popular opinion, bananas provide only about 9% of the daily requirem ent of potassium ; plantains about sam e. They supply about ½ the daily requirem ent of vitam in C. They contain 80-140 calories, with starchy plantains being the higher of the two. Ash from burned leaves and stem s is used as salt. Livestock are often fed banana culls. Fertilizers are m ade from dried, chopped banana stem s and leaves. There are dozens of construction and m edicinal uses for banana leaves and other plant parts. Som e extracts of banana have shown hypoglycem ic activity experim entally. The juice from the junction of a "branch" with the stem is used for toothache relief in Panam a and South Africa. The Musaceae is im portant not only for fruit production, but also for providing m an with clothing, tools, and shelter prior to recorded history. Costa Rican Fruits Cashew I. Taxonomy - II. III. Family Anacardiaceae Anacardium occidentale Originated in northeastern Brazil and was spread by the Portuguese to East Africa, Sri Lanka, India and Malaysia. Description - Plant: Smallish, spreading, evergreen tree of up to 10m in height. - Leaves: Oval to spatulate leaves have entire margins and blunt tips. - Fruit: The small kidney-shaped nut is borne on a yellow to bright red swollen pseudofruit known as the cashew apple. Nuts are surrounded by a thin inner membrane, a layer of irritant oil, and a though, leathery outer shell. The most widely produced tree nut crop in the world. Food value, usage - - The cashew apple and the roasted nuts can both be used for food. The main food item is the nut, which must be roasted to get rid of the irritant oil. Nuts contain high quality protein, oils, and starch. The fruits are used to make a variety of jams, jellies, juices, wines, and vinegars, including cajuado, a popular drink in Brazil. Cashews contain calcium, phosphorous and iron; as well as vitamins A, C, D, K and E. The apples are rich in vitamin A and contain as much as five times the vitamin C as citrus juice. Costa Rican Fruits Coconut I. Taxonomy • Cocos nucifera (Coco) The Arecaceae fam ily contains over 2600 species. Coconut is the m ost econom ically valuable and widespread species. • Grown pantropically in tropical lowlands. Coconut production is largely centered in the eastern hem isphere tropics, although Brazil produces about 5% of the world’s crop. Coconut ranks in the top 5 of all fruit crops in the world in term s of tonnage produced. • Coconut palm s are often the only tree species present on sm all, isolated, tropical islands. Fruits can float for years on ocean and still germ inate when beached. II. Description • • • Single-trunked palm to 20 m . Propagated by seed, fruit production in 6-9 years. Flowers of different sexes are borne in the sam e com pound spadix inflorescence in leaf axils. Flowering is continuous. Fruits are large, dry drupes in clusters of 10-20. The edible portion is endosperm , "m ilk" = liquid endosperm , “copra” = solid endosperm . Fruit ripen 16-18 m onths after pollination. The m esocarp is dry and fibrous, called “coir” and sold for industrial uses such as potting m edium . Endosperm rich in oil and protein; oil extracted for cooking. W orld's largest seed - since m ost of fruit is just the seed. III. Food value, usage • • Copra contains 39% oil, and 556 calories, on par with oil-rich nut crops. Other products include “coir”, the dry, fibrous m esocarp (potting m edia), coconut oil (cooking), coconut cake (left over from oil extraction; livestock), water coconuts - im m ature fruit used for drinking (the water inside is sterile). The coconut palm is referred to as the "tree of life", "tree of heaven", or "tree of abundance", reflective of its essentiality to everyday life in the tropics. The following is a quote from W orld Bank Technical Paper 136. “The im m ature nut provides a pleasant beverage (coconut m ilk or liquid endosperm - also used in tissue culture), the raw kernel is an im portant article of food; pared, shredded and dried it provides the desiccated coconut of com m erce. The oil is used for cooking, for illum ination and lubrication, and in the m anufacture of m argarine, bakery fats, soaps, detergents and toiletries. Coconut cake, the residue after extracting the oil from copra, is valuable as cattle and poultry feed. Tapping the inflorescence produces sap which can be used to provide sugar, vinegar, sweet or ferm ented toddy (like beer or wine) and, when distilled, arrack (liquor). The tim ber can be used for building and furniture construction; the plaited leaves for roofing; fiber from the husk for the m anufacture of ropes and m atting; the shell for charcoal or the m anufacture of artifacts (pots, buttons, bowls, etc.). Even the roots are used in dyes and traditional m edicines." The resin of inner husk used in Panam a for toothache relief. Coconut m ilk is an anthelm intic (rids intestinal worm s). Costa Rican Fruits Fig I. Taxonomy - II. III. Family Moraceae Ficus carica Originated in the Eastern Mediterranean region. One of the most ancient of all crops, archaeological records date cultivation as far back as 4000BC. Today figs are grown in all temperate regions of the world. Description - Plant: A small deciduous tree or shrub 4-7m high. - Leaves: Fairly large, lobed leaves; distinctive shape. - Fruit: The fig is type of multiple fruit known as a syconium; basically an inverted, hollow inflorescence, bearing numerous small flowers and fruits on the inside, with a small hole at the tip through which the pollinators can enter. Food value, usage - Figs can be eaten fresh or dried. Figs are used in cooking, desserts, confectionery, jams, preserves, and drinks. Figs are among the sweetest of fruits. Available carbohydrates are 13% in fresh and 55% in dried. They are very rich in vitamins and minerals and have a mild laxative effect. Costa Rican Fruits Grapefruit I. Taxonomy • • • C. paradisi, family Rutaceae introduced to Florida in 1809, and was not known by m an beforehand. Probably derives from Caribbean 'Forbidden Fruit' which was a natural hybrid between pum m elo (C. grandis) and sweet orange. Citrus’ native range is from northeastern India through the Malay archipelago and Australia. Grapefruit is the only citrus fruit to have originated in the new world. The USA leads the world in production; Costa Rica produces very little. II. Description • • • • Plant: Sm all, spreading, evergreen trees or tall shrubs. Stem s often arm ed with long thorns. Leaves are unifoliate, thick, ovate with acute to obtuse tips, having entire or crenulate m argins and a wide petiole wing. Leaves contain characteristic citrus oils in glands (“pellucid dots”) which m akes them fragrant when crushed. Flow er: Fragrant flowers are in short cym es, borne axillary on current flush of growth, and also from the previous flush of growth. 5 petals and sepals; petals linear, som etim es curved lengthwise, white, waxy, and thick; sepals fused at base to form a sm all cup. Ovary with 10-14 locules in m ost com m ercial cultivars, each with potentially 4-8 seeds. Ovary, superior, subtended by raised nectary disc. Pollination: Self-pollinating or parthenocarpic Fruit: A hesperidium . The endocarp (edible portion) is divided into 10-14 sections, separated by thin septa. Each segm ent is com posed of juice vesicles ("pulp"), with long stalks attached to the outer wall, containing juice. The m esocarp is the white tissue usually adherent to the outer surface of the endocarp; it is also called the albedo. The exocarp, or flavedo, is the thin, pigm ented outer portion of the rind, with num erous oil glands. III. Food value, usage • • Supplies 84% of vitam in C; 40 calories in 100 g serving. Sweeteners -. Naringin (flavonoid) - in grapefruit, has 1000x the sweetness of sugar. Said to be a long-lasting sweetness that is slow to develop - aftertaste like licorice or m enthol and Neohesperidin (dihydrochalcone) - flavonoid in C. grandis, a parent of the grapefruit. Costa Rican Fruits M yrtaceous Fruits, Guavas I. Taxonomy • • • • • The Myrtaceae fam ily is a broadly distributed group of (m ostly) tropical trees and shrubs, with centers of origin in Australia and Brazil. 80 genera, > 3000 species, m any native to or naturalized throughout tropical Am erica. exam ples include Eucalyptus, Callistemon (bottle-brush tree), Melaleuca, clove (dried flower buds of Syzygium aromaticum), allspice (unripe berries of Pimenta officinalis), and bay rum (Pimenta racemosa) The com m on guava, Psidium guajava , (guayabo) is the m ost im portant species (pictured at top). Other “guavas”: pineapple guava (Feijoa sellowiana), Arazà or Brazilian Guava (Eugenia stipitata - pictured at right)), Cattley guava, (Psidium cattleianum), and Costa Rican guava (Psidium Friedrichsthalianum). II. Description • • • The com m on guava is a sm all, often m ulti-trunked tree, and has striking bark- sm ooth, thin, copper-colored, exfoliating to reveal a m ottled tan/brown appearance (like a crape m yrtle). The m ain stem s are “bony” or “m uscled” in appearance. Young twigs are downy and arom atic when crushed. Flowers are white and have a raised tuft of white stam ens (m aybe 200 or m ore). Fruit is round or pear-shaped, yellow when ripe, 2-4" in diam eter, with prom inent sepal rem nants at the tip (like a pom egranate or quince). The flesh is generally salm on pink, but can be white, yellow, or red, and contains m any sm all (1/8"), hard, yellowish seeds. They appear to be self-fruitful. III. Food value, usage • • • • 50-100% of Vitam in A and 100-600% of Vitam in C (found m ostly in the outer skin). Calories 40-50. The wood is strong and fine-grained; useful in furniture. Good for fuel wood or charcoal. The leaves and bark are high in tannins, and therefore used for tanning hides. Also used to m ake dark colored dye. Leaves, roots, bark and im m ature fruit for halting diarrhea, vom iting, dysentery, upset stom ach; crushed leaves applied to wounds as a poultice or chewed for toothache relief; leaf decoctions for cough, throat and chest ailm ents. Costa Rican Fruits Inga I. Taxonomy - II. III. Family Fabaceae, genus Inga. There are about four hundred species in the tropics; about twenty-five to thirty occur in Costa Rica. Description - Plant: Inga species are large, canopy and sub-canopy trees recognizable by their alternate, even-pinnate, compound leaves, often bearing a winged rachis, and usually having glands between opposite leaflets. - Flower: Inga flowers are arranged inflorescences that are “puffballs”: the main part of each flower is the stamens, and it is the white filaments of the numerous stamens that provide the visual attraction. - Fruit: Inga fruits are large, leguminous pods of many shapes and sizes. They can be flat green pods, square brown fuzzy pods, or long twisted pods. The seeds are usually covered with white, sweet, edible pulp that aids in their dispersal by bird and mammals. Food value, usage - Many species of Inga are economically important as shade trees in coffee and cacao plantations. The fruits can be eaten and are commonly know as “guaba.” The though skin is easily removed by hand the white flesh may be eaten on its own. Costa Rican Fruits Jackfruit I. Taxonomy - II. III. Family Moraceae Artocarpus heterophyllus Believed to be indigenous to southern India but cultivated in Southeast Asia since ancient times. From here it spread to all tropical regions of the world. Description - Plant: Jackfruit is a fast growing tree of 10m or more in height, with the overall appearance of a wild fig tree. - Leaves: Ovate, glossy leaves have entire margins; no lobes or teeth in contrast to its close relative the breadfruit. - Fruit: Cauliflorous; borne directly on the trunk or large branches. Fruit are potentially the largest of any plant in the world. Oblong in shape, up to 1m long, sometimes upwards of 100 lbs, green in color and have a distinctive surface texture due to regularly spaced, small soft protuberances. The multiple fruit is formed from an entire flower cluster that becomes fleshy. It contains several hundred individual fruits, each with a large seed surrounded by orange-yellow flesh. Food value, usage - Jackfruit is relatively low in carbohydrates and energy value. It is a good source of potassium, iron and nicotinamide. - The yellow timber is popular for woodcarvings and furniture. Costa Rican Fruits Lime I. Taxonomy • • • • Genus Citrus, Rutaceae fam ily C. aurantifolia - lim es and lim e-like fruits. Two m ain cultivars include the 'Key', which is sm all, round, and seedy, and 'Tahiti', which is larger, oval, and seedless. Lim es are native to southeast Asia; they are m ore tropical in adaptation than the other m ajor citrus fruits. Mexico produces over 10% of the world’s lim es, and Costa Rica produces < 0.1%. III.

Sour orange - Said to be good for headache, fever, dysentery, ophthalm ia, oral infections, verm ifuge, vom iting. wash or gargle for sore throat. Myth/folklore - Because the orange tree bears flowers and fruits at the sam e tim e, it was used in fertility rituals and weddings - the white flower sym bolized virginity, and the fruits sym bolized fertility. Costa Rican Fruits Papaya I. Taxonomy • • • Carica papaya, Caricaceae fam ily. Native from Southern Mexico through Central Am erica. It was spread to the south by Indians, and throughout the Caribbean with Spanish exploration. Papaya ranks about 18 th in im portance as a fruit crop worldwide, with Brazil producing 25% of the world’s crop; although abundant in m arkets in Costa Rica, it produces < 1% of the world crop. II. Description • • • • Plant: Large, herbaceous perennial, to 10m , <6m in cultivation. Leaves are spirally arranged on a hollow stem (“trunk”), with petioles 1-3.5 ft in length and blades deeply lobed, 1-2 ft in width. Stem and leaves produce white latex. Flow ers: Plants are dioecious or herm aphroditic, with only & or herm aphrodites used in cultivation. Pistillate flowers are waxy, ivory white, and borne on short stalks, perfect flowers are sim ilar with bright yellow anthers. Pollination: Herm aphrodites self-fruitful, fem ales m ust be cross-pollinated. Fruit: Large, oval to round berries; m elon-like. Fruit borne axillary on the m ain stem . Fruits from fem ale flowers are m ore round in shape and thin-skinned, whereas fruits from bisexual flowers are the typical pyriform /oval shape with thicker skin. Flesh is yellow-orange to salm on at m aturity, the edible portion surrounding the large, central seed cavity. Hundreds of sm all black seeds (3/16 inch). Fruit production occurs year-round since flowering is continuous; individual fruits m ature in 120-150 days. Plants begin bearing in 8-10 m onths. III. Food value, usage • • • • • • Vitam in A @ 48% of RDA, Vitam in C @ 80%. Calories - 43. Milky latex m ay cause derm atitis. Toothache relief - the inner bark is used for this in Sam oa. Am ebicide - latex and seeds used in C. Am erica to kill Entamoeba histolytica which causes dysentery and liver abscesses. Cosm etics - papaya fruit pulp is the basic com ponent of m any facial cream s, salves, and sham poos. Papain - is one of two proteolytic enzym es (the other is chym opapain) found in papaya latex. Papain is extrem ely useful since it retains proteolytic activity over a wide pH range, unlike other proteases. Papain is used during surgical procedures to dissolve ruptured spinal discs; it is referred to as “nature’s scalpel” because it preferentially degrades dead tissue. Costa Rican Fruits Passion Fruit I. Taxonomy - - II. Description - Plant: A vigorous climbing vine with smooth, deeply lobed, toothed leaves and spiraling climbing tendrils. - Flower: The white/purple flowers are strikingly beautiful and contain numerous stamens and characteristic curved styles. - Fruit: An egg-shaped berry with a tough skin. It can be purple or yellow, and is somewhat wrinkled at maturity. It contains numerous seeds with fleshy, sweet or sour arils, containing the juice. Two types are grown: the common purple-fruited, sweet, black-seeded type which has the flowers open in the morning and the yellow-fruited sour, brown-seeded type which has the flowers open in the afternoon. - III. Family Passifloraceae Passiflora edulis is main species (pictured right); several other edible Passiflora species, such as sweet granadilla (P. ligularis pictured below). Indigenous to southern Brazil, Paraguay and Argentina. Introduced to the rest of the world by the Spanish; commercially important worldwide. Food value, usage - - Passion fruit is mainly eaten fresh or the fruit pulp is used in drinks, yogurts, and desserts. Purple fruits are preferred for eating, while the more acidic yellow type has become an important commercial source of juice for the beverage industry. The fruit pulp yields fair amounts of Vitamin C, carotenoids, Vitamin A, Phosphorous, and Potassium. Costa Rican Fruits Pineapple I. Taxonomy • • • Ananas comosus, Brom eliaceae fam ily ‘Sm ooth Cayenne' is the m ain variety, selected and cultivated by Venezuelan Indians for its large, juicy fruit and lack of spines on leaves. Native to southern Brazil and Paraguay, probably distributed throughout tropical Am erica and the Caribbean by Carib Indians. Pineapple achieves best quality in hot, tropical lowlands, and is drought tolerant enough to tolerate an extended dry season. Tiny Costa Rica boasts a #6 ranking in world pineapple production, and is the m ain exported to the USA. II. Description • Plant: Herbaceous m onocot, 1-1.5m tall and 1m wide. Short, central stem inconspicuous in the center of rosette of long (1-2m ), linear leaves, with spines at tips and m argins, except m any cultivated types which are spineless. • Flow ers: Sm all, purple-red, subtended by a single yellow, green or red bract, borne laterally on elongating central stem in a spike of 100-200 individuals. Apex of inflorescence is vegetative, becom ing the "crown" on the fruit, which can be used for propagation. Flowering induced by chem ical/ethylene exposure when plants are 6-12 m onths. • Pollination: Flowers self-sterile; seedless fruit are set parthenocarpically. • Fruit: A cone-shaped, m ultiple of berries, form ed from the fusion of adjacent flowers on the spike, and developm ent of ovaries into the fleshy, edible portion. The "core" is the fleshy rachis of the spike. Fruit covered with waxy, leathery rind, m ade up of hexagonal "eyes", arranged spirally, which denote the position of individual flowers. One fruit per plant is produced. Plants generally produce fruit in 15-18 m onths from transplanting. III.
