Abstract: This paper mainly studied the process of rice bran beverage extraction from stabilized rice bran especially the enrichment of γ-oryzanol in the products.Through individual factor analysis and orthogonal test,the various enzymes,emulsifiers and the conditions of the use of enzymes were studied.Finally,the optimal additive and the optimal conditions of processing were obtained,through which the 1.15% level of γ-oryzanol in the product could be obtained fron 0.5% in the rice bran.

Key words: Rice bran &gamma, -oryzanol enzyme hydrolyze Beverage technology Emulsifiers Orthogonal test；
