Abstract: The enzymatic esterification of soybean oil deodorizer distillate (SODD) with methanol catalyzed by lipase was studied. The single factor and orthogonal test were undertaken in order to get the optimal combination parameters. The results showed that the important factors affecting the esterification ratio are the esterification time and the lipase concentration, while esterification temperature and the molar ratio of substances have little effect. The optimum factor combinations are : the molar ratio of substances 1:1.5, lipase concentration 60plu/g, esterification temperature 60℃ and esterification time 8 hours. Under these conditions, the optimun esterification ratio is 94.78%.
