A process of an enzymatic interesterification in a low water content condition, which comprises subjecting a reaction liquid containing (a) a fat or oil and (b) a member selected from the group consisting of (i) another fat or oil, (ii) a fatty acid ester with a lower alcohol and (iii) a fatty acid to the action of a lipase in the form of dried Rhizopus cells while maintaining the water concentration between 5 and 1000 ppm in the reaction liquid during the reaction. In accordance with the process of the present invention, an interesterification of fat or oil can be carried out efficiently in a high yield.

Process of enzymatic interesterification maintaining a water content of

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.
