Abstract
A process for producing diglycerides is provided by which high-purity diglycerides can be produced at a lower cost and more efficiently than conventional esterification and glycerolysis processes, and which inhibits the deterioration of oil quality, such as discoloration, and the loss of trace active ingredients derived from a feedstock of fats and oils, which involves partially hydrolyzing a fat or oil, followed by esterifying the resultant product with glycerol.
