ABSTRACT Lychee juice is one of high nutritional value beverages, but its taste is not attractive to consumers. Because the flavoring agent accounts largest amount in the lychee juice is phenethylalcohol in the form of compounds, therefore, it is not able to evaporate leading "sinking” flavored lychee juice. The aim of this study is to determine the tecnology parameters in process of using β-glucosidase enzyme was extracted from apricot kernels to release phenethyl alcohol from the compound - form to the free-form, thereby increasing flavor of the lychee juice. From the experimental material was lychee juice, the experimental single and multiple factors were implemented. Optimization results are shown the optimal condition for the enzyme concentration processing was 350UI/ml lychee juice treated at a temperature of 350C for 90 mins. This method increased the amount of free phenethylalcohol - the main flavoring agent for lychee juice - more than 8 times without affecting other components in the lychee juice.
