PROBLEM TO BE SOLVED: To provide a method for producing a new triglyceride in which a structural lipid considered as a human breast milk type triglyceride structure, i.e., the 2-position of the triglyceride is a 16-18C saturated fatty acid and at least one of unsaturated fatty acids bound to the 1- and the 3-positions areω3-,ω6- and/orω9-based unsaturated fatty acids. SOLUTION: A triglyceride having <=45 deg.C melting point in which a fatty acid at the 2-position is a 16-18C saturated fatty acid and fatty acids at the 1- and the 3-positions are once converted into medium-chain fatty acids is used as a raw material or the process is passed through the resultant triglyeride as an intermediate to thereby produce the objective triglyceride when making a lipase capable of specifically acting on ester bonds at the 1- and the 3- positions act on a glyceride in which the 16-18C saturated fatty acid is bound to the 2-position and producing the triglyceride in which the fatty acids at the 1- and the 3-poditions are converted intoω3-,ω6- and/orω9-based unsaturated fatty acids according to a transesterification.
