Study on Hydrolysis of Corn Germ Protein with Aid of Papain

The hydrolyzation on corn germ protein with papain was studied.The effects of temperature,pH, and time on degree of hydrolysis were analyzed.The optimum hydrolysis conditions were determined: 60℃,pH 7.0, 4 000 U/g,90 min.In these conditions the degree of hydrolysis is 14.60%,and the hydrolysis product is not bitter.
