磁性固定化胃蛋白酶水解牛奶的研究

Study on Hydrolysis of Milk by Magnetic Immobilized Pepsin

将磁性固定化胃蛋白酶应用于牛奶的水解。结果表明,其对牛奶水解有一定的催化作用,最佳水解条件为:磁性固定化胃蛋白酶添加量1.50 g、pH值4.0、水解温度60℃、水解时间2 h,此时牛奶水解度可达40%以上。

Magnetic immobilized pepsin was applied to hydrolysis of milk. The optimum hydrolization conditions for milk by magnetic immobilized pepsin were determined as follows, pH value 4.0,hydrolyzation temperature 60℃, hydrolyzation time 2 h and the addition amount of magnetic immobilized pepsin 1.50 g. The hydro- lyzation rate of milk could be above 40%.
