When fatty acid containing 35% by weight of trisaturated fatty acid glyceride (SSS) is mixed with oil or oil of 35 or more, the fatty acid (s) in the whole fatty acid is 45 to 75% by weight, and unsaturated fatty acid (U) is 25 to 55% by weight In order to produce a mixture of oils and fats, (1) the step of esterifying the oil \/ oil mixture by lipase (2), and the SSS content contained in the oil after the transesterification is x (weight%), and the solid fat content during crystallization is set to y (%) In order to obtain the oil and fat containing the liquid and the solid part until the value of X-Y is crystallized without using a solvent until the value of X-Y is obtained (3), and the liquid part is separated by separating the oil and fat, the fatty acid composition of the trisaturated fatty acid glyceride is produced Manufacture.トリ飽和脂肪酸グリセリド(SSS)を35重量%以上含む油脂と、ヨウ素価35以上の油脂とを混合することにより、構成脂肪酸全体中飽和脂肪酸(S)が45~75重量%、不飽和脂肪酸(U)が25~55重量%となる油脂混合物を作製する工程(1)、該油脂混合物をリパーゼによりエステル交換する工程(2)、及びエステル交換後の油脂中に含まれるSSS含量をX(重量%)とし、晶析時の固体脂含量をY(%)としたとき、X-Yの値が2~13になるまで溶剤を用いずに晶析し、液状部と固体部とを含む油脂を得る工程(3)、さらに該油脂を分別して該液状部を分取する工程(4)に従って、トリ飽和脂肪酸グリセリド含有油脂組成物を作製する。
