Optimum research on the technology conditions of soy peptides by composite enzymatic hydrolysis
This article used one new method to determine the quantity of elements molecular soybean peptide(molecular weight≤2300).Using soy protein isolates as materials,employ Protamex enzyme and Neutrase enzymatic hydrolysis soybean.In this research,the role conditions of Protamex enzyme and Neutrase enzyme were compared and contrasted,the best technology condition of enzymatic hydrolysis was determined by orthogonal test.The result showed that the best technology condition was that the composite enzymes(Protamex:Neutrase)were 6∶4,pH7,the substrate concentration was 5%,the hydrolysis time was 8 h,temperature was 60 ℃,These conditions produced small measure to further hydrolysis of functional elements soybean peptide large study has some significance.
