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 hydroly...
