中文摘要：

比较单宁酶、脂肪酶、猪胰脂肪酶、木瓜蛋白酶、胰蛋白酶、糖化酶、果胶酶和α-淀粉酶对酯型茶黄素（TFDG）的水解效果,并对最佳水解酶的反应条件进行优化。结果表明,单宁酶水解酯型茶黄素的效果最好,其反应最佳条件为反应体系的温度40℃、pH值5.0、酶浓度2.4mg/mL、最佳反应时间120min。水解后茶黄素中简单茶黄素（TF）的含量从52.51mg/g提高到199.84mg/g。

英文摘要：

The research was designed by using enzymes including tannase,lipase,porcine pancreatic lipase,papain,trypsin,glucoamylase,pectinase and α-amylase,to compare the hydrolytic effect of estertheaflavins（TFDG） and to obtain the optimum reaction conditions of the best hydrolase was selected.Results showed that the optimum condition were as follows： temperature of reaction system 40 ℃,pH 5,enzyme concentration 2.4 mg/mL,reaction time 120 min.The content of TF increased from 52.51 mg/g to 199.84 mg/g under these optimum conditions.
