摘要
Abstract
The tea polyphenol separated from green tea was used as the raw material of preparing tea pigment, and the effects of two kinds of preparation and analysis methods (chemical oxidation method and enzymatic oxidation method) on the gain rate and main components of tea pigment (the oxidative product of tea polyphenol) were explored. The results showed that:in chemical oxidation system, increasing the dosage of K3Fe( CN)6 was good for the accumulation of theaflavins content, but the gain rate of tea pigment declined. The theaflavins content was as high as 52. 73% in tea pigment obtained by enzymatic oxidation method, which was significantly higher than that did by chemical oxidation method.关键词
