复合酶法提取茶多酚工艺条件研究

THE STUDY ON THE TECHNICAL CONDITIONS OF EXTRACTION OF TP FROM TEA LEAVES WITH MULTIPLE ENZYME

实验采用复合酶解法在低温下提取茶叶中的活性物质——茶多酚。采用单因素和正交实验确定了最佳提取条件。结果表明,采用复合酶法提取茶多酚,提取率高达98%以上,茶多酚中的活性成分儿茶素相对含量较传统沸水提取法高出9%～10%。

Using multiple enzyme to extract tea polyphenols （TP） from tea leaves at low temperature. The optimal extraction parameters and the extraction rate were studied by single factor and orthogonal experiments. It indicates that, with multiple enzyme method, the extraction rate of tea polyphenols was up to 98 % and the extraction rate of tea catechins, which was main active component of tea polyphenols, was 9 %-10 % increase than that of traditional method with boiling water.
