For deepen using tea leaf, the technology of extraction, purification, isolation of tea protein, and chemical characterization, functional properties of tea protein were studied.
茶叶中含有21%~28%的蛋白质,茶叶蛋白具有一定的保健功能,是一种未被充分利用的蛋白资源。
The suitable parameter of tannase applying to green tea extract was discussed;the difference of enzymolysis effects by different proteinase (papain, bromelain, neutral proteinase, proteinase M and umamizyme) was analyzed;a suitable proteinase for hydrolyzing tea protein and its optimal technologic parameter were selected.
本研究以蒸青绿茶为原料,研究了单宁酶对绿茶提取液品质的影响,分析了单宁酶处理对绿茶提取液滋味和浑浊度的影响,探讨了单宁酶应用于绿茶提取液的最佳作用参数;分析比较了不同来源的蛋白酶(木瓜蛋白酶、菠萝蛋白酶、中性蛋白酶、蛋白酶M、鲜味酶)酶解效果的差异,筛选一种比较适合用来分解茶叶蛋白的蛋白酶及其最佳工艺参数;对单宁酶/蛋白酶复合酶对绿茶提取液的处理效果进行了分析;初步探讨了茶叶蛋白的提取工艺。
