Novozym 435 was used for the synthesis of vitamin A plamitate. The influences of solvent, the molar ratio of substrates, the reaction temperature and time, and the water concentration were optimized and the best result was obtained by interesterification from 0.200 g vitamin A acetate and 0.468 g palmitic acid, at 30℃, in 10 mL hexane, containing 0% of water, with 10% of lipase(mass ratio, immobilized lipase to vitamin A plamitate). In these conditions, 75% of vitamin A acetate was converted into vitamin A plamitate. The immobilized lipase was reused about 6 batches.
