摘要/Abstract

摘要： 用云南、湖北、浙江生产的三种紧压茶、浙江绿茶、儿茶素和有机酸对胰酶进行活性影响实验,结果显示,所有的处理对胰蛋白酶和胰淀粉酶均有很高的激活效果,其中云南砖茶对上述二种酶的促活作用最强,达到17.2倍和15.6倍,绿茶次之。但上述处理对脂肪酶活性却略有抑制作用。在用云南紧压茶、绿茶的酵母发酵液和绿茶进行乳酸杆菌和双岐杆菌的激活效果试验中,所有的处理均显示了一定的激活作用。其中前两者处理的乳酸杆菌生长液菌体量高于对照的40%,而绿茶的酵母发酵液处理的双岐杆菌生长液菌体量高于对照的62.5%。

Abstract: The effects of some tea infusions,catechins,and organic acids on the activities of three enzymes and two microorganisms were investigated.The results showed that activities of proteinase and α-amylase extracted from pancreas were improved by tea infusions,catechins,and organic acids.Yunnan compressed tea improved the activities of α-amylase and proteinase by 17.2 and 15.6times respectively.All the treatments mentioned inhibited the activities of lipase in different degrees.Yuannan compressed tea,fermented green tea solution and green tea infusion appeared to have high abilities to promote the growths of Lactobacillus bulgaricus and Bifidobacteriam.The dried weight of Lactobacillus bulgaricus cultured in either Yuannan compressed tea or fermented green tea solution was 40.0% higher than that cultured in physiological saline,and also higher than that cultured in green tea infusions.However,Fermented green tea solution showed the best effect on stimulating Bifidobacteriam growth among the three treatments.It increased 62.5% weight higher than that cultured in physiological saline.
