The High Protein of the Rice Protein Peptide Preparation and the Product Nutrition Ingredient Analysis

The experiment took rice residue as material,Through the pretreatment and the restrictive enzymolysis to the rice residue,Spray drying obtained the rice protein peptide powder after the enzymolysis fluid concentration.The optimum conditions of enzymatic hydrolysis of rice dregs were as follows:the enzyme amount of 1%,temperature 50 ℃ at pH 8 for 3 hours,ratio of solid/ liquid at 1∶5;Equally,we had a research on nutritional ingredient of the rice protein peptide product: protein content and the molecular weight,the short peptide content,the amino acid composition analysis.The result displayed: The product protein content was 91.5%,the majority of molecular weight was under 3 000,the short peptide content was 77.87%,the essential amino acids content was rich,the rice protein peptide product took one kind of high quality albumen,we should take further exploitation on application value of the rice protein peptide e and utilize it into food better.
