【Abstract】 Glycerin was added to esterify with free fatty acids in rice bran oil containing high acid value under the conditions of high temperature, high vacuum and being catalyzed. The single facor experiments and orthogonal test showed that esterification by glycerin reacting with free fatty acids could reduce the high acid value in rice bran oil effectively (less than 4) and significantly increased the refining rate.更多还原
