摘要
The aim of this work is to synthesize lauric acid phytosterol esters by lipase in solvent-free system. The lipase was immobilized on macroporous resin NKA, with addition of dextran. The reaction conditions were optimized. The results showed that under the optimized conditions of a molar ratio of lauric acid to phytosterol of 6:1, 7.5% dextra of molecular weight 10 kDa and the reaction temperature of 60℃ in solvent-free system, the esterification rate reached 96.2% after 12 h. The reaction time of the synthess of phytosterol esters decrease 4 h comparing with the immobilized lipase on a macroporous resin.
