Enzymatic Preparation of Rice Residue Solubility Protein Powder

This paper studied the combined enzymolysis experiment of protamex and flavorezyme to the rise residue concentrated protein.On the basis of single factorial experiments,the enzymatic hydrolysis conditions was optimized by orthogonal test,and the extraction rate of rice residue protein in hydrolysate was 57.81%.When the hydrolysate was hydrolysised by flavor proteinase once again,the extraction rate of rice residue protein could reach 63.6%;and once the enzymatic product was frozen and dried,the protein rate of the rice residue solubility protein powder was 84.62%.
