EFFECTS OF ENZYMATIC HYDROLYSIS ON ISOLATION YIELD OF POLYPHENOL FROM VIETNAM GREEN TEA (CAMELLIA SINENSIS) LEAVES

Abstract

Enzyme Laccase obtained from Ganoderma Lucidum mushroom farm is used
for enzymatic hydrolysis of waste green tea (Camellia Sinensis) leaves. Amount
of polyphenol isolated from products of enzymatic hydrolysis was compared with
amount of polyphenol isolated from without-enzyme hydrolysis products.
Results showed that enzymatic hydrolysis of materials increased isolation yield
of polyphenol more than 10% compare to without-enzyme hydrolysis. Moreover,
enzymatic hydrolysis did not affect EGCG which is well-known as a high value
bioactive compound in Camellia Sinensis.
