Abstract: Attempt was done to prepare food supplements with high content of c 9, t 11-CLA or t 10, c 12-CLA. A free acid mixture containing CLA isomers was esterified with ethanol by enzyme catalysis. Novozyme 435 and Lipase AY30 were screened, and Lipase AY30 was employed to catalyze esterification reaction because of its high fractionation efficiency. Effect of reaction conditions on total esterification was investigated, and the optimal reaction conditions were: 140 U of lipase amount, reaction temperature at 50 °C, a pH of 6.5, and molar ratio of FFA–CLA to ethanol at 1:1. Based on the studies above, experiments of esterification and purification were done, and the best fractionation efficiency was obtained when the total esterification was 37%, and the corresponding purity and recovery of c 9, t 11-CLA were 75.50 and 49.85%, and that of t 10, c 12-CLA were 72.02 and 62.32%.
