Abstract Flavourzyme roteinase and protamex proteinase were used to hydrolyze hydrolyze soy protein and shrimp powder at the same time to prepare peptide.The optimum hydrolysis conditions 3:2 was the proportion of soy protein and shrimp powder as substrate,which concentration 11.0%,the dosage of flavourzyme 1.0%,the dosage of protamex 1.0%,temperature 55℃,pH7.0,hydrolysis time 4 hours,the test hydrolysis degree was 29.0% under these conditions.
