Abstract

The reacting conditions for hydrolysis of casein from milk by trypsase were researched through the single factor and the orthogonal test. The results showed that: the optimum conditions for hydrolysis of casein by trypsase were: pH 7.5,temperature 60 ℃,the concentration of substrate 5 %, the amount of enzyme 62.44 U/g, the lasting time of hydrolysis 140 min.Under these conditions, the degree of casein hydrolysis was 16.8 %.
