摘要: 采用正交试验,对果胶酶和纤维素酶催化浸出米糠油条件进行了研究。结果表明:酶催化浸出米糠油最佳工艺为:先用果胶酶和纤维素酶酶解处理,料液比(W/V)比1:5,果胶酶用量1.5%,纤维素酶用量2.0%,pH5.0,酶解温度50℃,水解5h,再用正己烷浸提米糠油。经过纤维素酶和果胶酶酶解处理后米糠油提取率比单独溶剂浸提法提高了31.9%。

Abstract: Orthogonal test design was used to optimize the extraction conditions of rice bran oil by pectinase and cellulase hydrolysis.The results showed the optimal extraction conditions of rice bran oil are as following:ratio of substrate to solution 1:5,pectinase amount 1.5%,cellulase amount 2.0 %,pH 5.0,temperature 50 ℃,hydrolysis time 5 h,and hexane as extraction solvent.Compared with single hexane extraction,the enzymes assisted extraction rate of rice bran oil is higher 31.9%.
