Provided is a high-diacylglycerol-content fat containing [alpha]-linolenic acid in a large amount, the fat being inhibited from crystallizing at low temperatures and being less apt to opacify or form a precipitate. The fat is a fat composition which satisfies the following (1) to (4): (1) the fat includes fatty acids as a component thereof, the fatty acids having an [alpha]-linolenic acid content of 40 mass% or higher, (2) in the fatty acids as a component of the fat, the total content of C16 saturated fatty acids and C18 saturated fatty acids is 6 mass% or less and the content of the C18 saturated fatty acids is less than 3 mass%, (3) the ratio of the mass of the C16 saturated fatty acids (P) to the mass of the C18 saturated fatty acids (S) in the fatty acids as a component of the fat, (P)/(S), is 0.1 or higher but less than 3.5, and (4) the fat has a diacylglycerol content of 25 mass% or higher.本發明提供一種抑制低溫下之結晶化而不易產生白濁或沈澱之富含α-次亞麻油酸之高濃度含有二醯甘油之油脂。 本發明之油脂組合物滿足以下之(1)～(4)： (1)構成油脂之脂肪酸中之α-次亞麻油酸之含量為40質量%以上； (2)構成油脂之脂肪酸中之碳數16之飽和脂肪酸與碳數18之飽和脂肪酸之合計含量為6質量%以下，並且碳數18之飽和脂肪酸之含量未達3質量%； (3)構成油脂之脂肪酸中之碳數16之飽和脂肪酸(P)相對於碳數18之飽和脂肪酸(S)之含有質量比［(P)/(S)］為0.1以上且未達3.5；及 (4)二醯甘油之含量為25質量%以上。
