摘要：

The syntheses of fructose butyrate with five different immobilized porcine pancreas lipases were studied in acetonitrile with butyric acid and tributyrin as acyl donors. The hydrolytic activities of the enzymes were measured during the syntheses. The transesterification yield was the highest with the Celite-adsorbed enzyme: 57% (1.42 g fructose butyrate l(-1)), and this form exhibited the highest degree of hydrolytic activity preservation (57%) after operation for 20 days.
