高变性豆粕中蛋白质水解特性的研究

STUDY ON THE HYDROLYSIS CHARACTER OF THE PROTEIN IN THE HIGHLY DENATURED SOYBEAN MEAL

就高变性豆粕的胰蛋白酶水解问题进行了研究，指出胰蛋白酶水解蛋白质的最适温度为４５℃，最适ｐＨ值为８０。水解高变性豆粕的最佳条件为：温度４５℃，ｐＨ值８０，时间为６ｈ，底物浓度为９０％，酶量／底物为８０００Ｉ·ｕ／ｇ。在此条件下。

The problem that the highly denatured soybeen meal is hydrolased by typsin is studiedThe optimum temperature of typin by obolysis protein is 45℃and the optimum pH value is 80The optimum conditions of the hydrolytic highly denatured soybean meal are the following:temperature:45℃,pH value 80,time:6 hours,substract concertraction 90%enzyml/substract 8000 I·U/g。In such a conditions 6315% protein in the highly denatured soybean meal will hydrolysis and digest
