It is intended to provide a method for efficiently producing a diacylglycerol-rich fat and/or oil that has a low content of trans-unsaturated fatty acids and has a good color and a good flavor characteristic to diacylglycerols. A method for producing a diacylglycerol-rich fat and/or oil, by hydrolyzing a raw fat and/or oil by an enzymatic splitting method, and subjecting the fatty acids and glycerin obtained thereby to an esterification reaction, wherein a raw fat and/or oil containing undeodorized fat and/or oil in an amount of 50% by weight or more is used, and a deodorization treatment is carried out after the esterification reaction, to the extent that the relationship between the deodorization time (x) and the deodorization temperature (y) satisfies the following conditions (i) and (ii):
(i) y ‰¥ -2.59x + 566
(ii) y ‰¤ 617x -0.0455 (provided that 475 ‰¤ y ‰¤ 563)
wherein x represents the deodorization time (minutes), and y represents the deodorization temperature (K). |
