Interestification of fats

摘要

A process of an interesterification reaction of fats, wherein a fatty acid moiety of a glyceride is substituted by other fatty acid moiety, and the reaction is accelerated by a catalyst and is continued constantly at a high rate for a long time. The process uses a dry cell for a catalyst. The dry cell is prepared from a lipase-containing microorganism by cultivating it to increase a lipase content and drying it to control water content.
