摘要
试验比较了米糠粒度、料液比对酶法浸提米糠油出油率的影响。正交试验确定最佳酶解工艺条件。结果表明:米糠过40目筛,配制料液比(W/V)为1∶5的溶液,加入纤维素酶1.2%,蛋白酶0.6%,淀粉酶0.3%,在pH值为4.5,温度55℃条件下酶解6 h,出油率达到87.83%。
The effects of rice bran particle size, solid-liquid ratio on the extracting rate of rice bran oil were investigated by using enzymatic extraction method. The optimum enzymolysis technology conditions were determined through orthogonal design and test. The results show that the rice bran was sifted through a 40 mesh sieve, put up as a solution with solid-liquid ratio （m/V） of 1 ： 5, added cellulase 1.2%, protease 0.6%,amylase 0.3%; treated under conditions ofpH 4.5, temperature 55℃ and enzymatic hydrolysis time of 6 hours, the extracting rate reached 87.83%.
