Abstract: A method for stabilizing rice bran with complex enzyme involving enzymatic hydrolysis combined with thermal processing to stabilize rice bran, includes compounding at least one of glycosyl hydrolases such as cellulase, hemicellulase and alpha amylase into a complex enzyme solution, and performing enzymatic hydrolysis on the rice bran with the complex enzyme solution, and after enzymatic hydrolysis, performing thermal processing and inactivating enzyme treatment on rice bran using the moist-heat method, microwave method and/or extrusion expansion method, to prepare the stabilized rice bran. From the perspective of reducing bound lipase from rice bran, the glycosyl hydrolase is used to catalyze conversion of bound lipase in rice bran into free lipase, thereby effectively improving inactivation efficiency of rice bran lipase. The rice bran prepared using the method has characteristics of low residual activity of lipase and long shelf life, and may be directly applied to industries such as food and cosmetics.
