Title of project: Control of diseases and physiological
disorder in fresh-cut fruits using
phenyllactic acid bio-compound
Objective: Prolong the shelf-life of fresh-cut fruits (orange,
pineapple) towards higher food quality and
hygiene, increase of economic values and
living standard
Fresh-cut fruits
Consumption with double digit growth
+
Demand for diversified forms of fruits
+
Most fruit is consumed at home
=
Great opportunity for
FRESH-CUT FRUIT
Phenyllactic acid (PLA)
C6H5CH2CHOH==COOH
 A novel antimicrobial compound with
broad inhibitory activity, higher
stability and safety
Gram(+) and gram(-) bacteria.
Fungi (mycotoxigenic species)
 Anti-oxidant property
 Practical application as a novel
bio-preservative in the food industry.
 Intl. research on PLA: quite new
(1998-2008)
