摘要
以可溶性蛋白含量为评价指标,主要研究不同蛋白酶处理米糠的最佳工艺条件。结果表明:研究所用的几种蛋白酶中,中性蛋白酶提高米糠蛋白溶解性的效果最明显(达56%),高出对照2倍。最佳酶解条件为:米糠与水料液比1∶8、酶添加量3%、酶解温度45℃、酶解时间3 h。
Optimum enzymatic treatment of different proteases was studied for improvement of soluble protein in rice bran. It is showed that: Neutrase is the most effective on improvement on the solubility of rice bran protein among Neutrase, Alcalase and Ravourzyme. The optimum enzymatic hydrolysis conditions are as follows: ratio of rice bran powder water is 1:8, addition of enzyme is 3%, and treated at 45 ℃ for 3 h.
