ABSTRACT:
The process for producing an oleaginous composition of the present invention comprises transesterifying a fat containing a large amount of polybasic unsaturated fatty acid(s) as constituting fatty acid(s) with saturated fatty acid(s) and/or saturated fatty acid alcohol ester(s) with the use of a lipase having an site-specificity to thereby give symmetric triglyceride(s) wherein the fatty acid groups at the 1- and 3-positions are selectively transesterified and a polybasic unsaturated fatty acid group is present at the 2-position. The above transesterification should be carried out under such conditions as to give an oleaginous composition which comprises 40% or more of symmetric triglyceride(s) each having a polybasic unsaturated fatty acid group at the 2-position and 50% or more of completely saturated fatty acid(s) each having 16 or more carbon atoms.
