A process for the production of a composition comprising 1,3-dioleoyl-2-palmitoyl glyceride (OPO) comprises: providing one or more palm oil stearin fractions comprising tripalmitoyl glyceride and having an iodine value between about 18 and about 40； interesterifying the one or more palm oil stearin fractions to form a randomly interesterified palm oil stearin； subjecting the randomly interesterified palm oil stearin to enzymic transesterification with oleic acid or a non-glyceride ester thereof using an enzyme having selectivity for the 1- and 3-positions of a glyceride； and separating palmitic acid or palmitic non-glyceride esters from the product obtained in (iii) to form a composition comprising OPO glyceride.
