摘要

Abstract

Immobilization of cellulase on carrier of chitosan beeds crosslinked by glutaraldehyde were studied, and applied the immobilized cellulase to the hydrolysis of the summer green tea. Through the orthogonal test, the optimal extract technology has been investigated: adding 1.0 g immobilized cellulose enzyme in 1.0 g green tea, the ratio of tea and water is 1 : 20, and extracted 50min under 55 ℃. Compared to the traditional tea extraction method by hot water, the contents of tea polyphenols, amino acid and caffeine increased by using this technology, and the ratio of polyphenol to ammo acid was decreased. The immobilized cellulase still maintain a high activity, the relative activity of enzyme was more than 80%, after 7 times extraction.
