Abstract
The transesterification method is conducted with a powdery lipase wherein the powdery lipase is dispersed in ester-containing starting materials in the presence or absence of an inert organic solvent, and the diameter of at least 90% of the dispersed lipase particles is kept in the range of 1 to 100 .mu.m in the course of the trans-esterification reaction. A reactivity higher than that realized by the conventional transesterification method with a powdery lipase is obtained and the lipase can be easily recovered and reused, without causing a loss of the lipase activity, lowering of the conversion due to the residence of the substrate on the immobilizing carrier and side reactions caused by water introduced into the reaction system by the immobilizing carrier.
