乳蛋白质酶水解特性的研究

A Study on the Characteristics of the EnzymaticHydrolysis of Milk Protein

初步探讨了乳蛋白质酶水解特性，得出了最佳酶及酶解条件：乳蛋白质在ｐＨ值８、温度４０℃条件下加入６０００Ｕ／ｇ胰蛋白酶，水解时间１２０ｍｉｎ，乳蛋白质水解的效果最好。另外，双酶分段水解比单一胰蛋白酶的水解效果好，以木瓜蛋白酶＋胰蛋白酶水解效果为佳。

The properties of the enzymatic hydrolysis of milk protein are discussed.The optimum conditions were:pH 8.0,temperature 40℃,6000u/mg (protein) trypsion and hydrolysis time 120min.And the effect of hydrolysis with double enzymes was better than that with single enzyme.The double enzymes were papin and trypsion.
