Abstract
The present invention relates to a process for producing oils and fats rich in diacylglycerol by subjecting fatty acids which are obtainable by hydrolyzing raw material oils and fats, to esterification with glycerin, wherein the process comprises decreasing an anisidine value of greater than 6 of the raw material oils and fats or reaction intermediates, by 20% or more. By using the process of the present invention, even in the case of using a raw material having an anisidine value which is likely to increase in the production processes for raw material oils and fats or for oils and fats rich in diacylglycerol, the stability of the final product oils and fats rich in diacylglycerol is enhanced, and coloration is suppressed, so that products having excellent external appearance can be obtained.
