摘要
Abstract
In this paper , wheat bran was supposed as raw material , and alkaline protease was used to hydrolyze the protein .Making the protein yield as a target , chose univariate and quadrature methods to study on protein preparation of wheat bran .The results showed that the optimal conditions were as follows:solid-to-liquid ratio of 1∶10 , extraction time of 5 h with 0.5%addition of alkaline protease and pH value of 10.0 at the hydrolysis temperature of 50 ℃.Under these conditions , the yield of protein was 80.83%.The characteristics of protein from wheat bran were researched .The results showed that the solubility of protein was 63.6%; the emulsibility was 68.3%; the emulsion stability was 48.8%; the water holding capacity was 1.38 g/g, and the oil absorbency was 1.4 mL/g.关键词
