DEVELOPMENT OF LYCOPENE RECOVERY AND SOLUBILIZATION BY MICROEMULSION SYSTEM

摘要

A method for preparing a concentrated lycopene extract is provided to obtain high-concentration lycopene efficiently from watermelon by using an emulsifying solution. A concentrated lycopene extract is prepared by the steps of: (a) collecting the flesh of watermelon, grinding/centrifuging it by a chopper, a colloid mill and a homogenizer, and separating the centrifuged flesh into cake and serum; (b) putting a 0.5% Tween 20 emulsifying solution to the dried cake in a weight ratio of 20:1, and vibrating them at room temperature for 1hr to promote extraction; and (c) removing sediments through centrifuging/filtering processes. The concentrated lycopene extract is used as the ingredient of a functional food.
