Study on Improving Solubility of Rice Protein with Enzymolysis

Abstract

Abstract: The objective of this research is to improve solubility of rice protein. According to the reaction curve of enzymolysis, alcalase is the best enzyme among the selected enzymes, such as neutrase, protamex, flavourzyme, pepsin, papain etc. With the orthogonal test to optimize the reaction condition, the solubility of alcalase enzymatic hydrolysate was up to 43.12%. When the rice protein was hydrolyzed by alcalase and then by protamex, the solubility was up to 71.46%. The effect of combination of alcalase and other enzymes was worse. When the rice protein was hydrolyzed by protamex and then by alcalase, the solubility was only 54.73%. All these showed that different enzymes had different hydrdysis properties to rice protein.

Key words: rice protein, enzymolysis, solubility
