    摘要： The present invention provides a process for preparing a diglyceride, which includes:in an enzyme-packed tower which includes an immobilized lipase preparation, carrying out an esterification reaction between:(1) an acyl group donor selected from the group including a fatty acid, a lower alcohol ester thereof, and a mixture thereof; and(2) an acyl group acceptor selected from the group including glycerol, a monoglyceride, and a mixture thereof;to obtain a reaction fluid from the enzyme-packed tower;reducing a water content or a lower alcohol content in the reaction fluid; andsubsequent to the reducing, recirculating the reaction fluid to the enzyme-packed tower, wherein a residence time of the reaction fluid in the enzyme-packed tower is 120 seconds or less;to obtain a diglyceride. According to the present invention, a high-purity glyceride can be provided at a high yield in a short period of time.
