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%.
Key words�� pectinase   cellulase   rice bran oil   extraction rate
