Enzyme-assisted extraetion has been reported for extraction of carotenoids from marigold flower [48], vanillin from vanilla green pods [49], oil from coconut or seeds [48, 50] and phenols from blaek eurrant and herb [51, 52], The enzyme-assisted extraction mechanism is based on eell wall degrading capacity of enzymes glucanases and pectinases which can weaken or break down the eell wall permitting the intracellular materials release and more aeeessible for extraction.
