A study on preparation of mixed protein peptide by double enzyme and microwave

Under the microwave heating,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 were: 3∶2 was the proportion of soy protein and shrimp powder as substrate,which concentration 12.0%,the dosage of flavourzyme 1.33%,the dosage of protamex 0.67%,temperature 60 ℃,pH 6.0,hydrolysis time 50 min,the test hydrolysis degree was 29.6% under these conditions.
