Abstract
A process for producing triglycerides comprises: (a) subjecting a first triglyceride comprising at least 40% by moles of oleic acid residues, based on total acyl groups in the triglyceride, to a reaction with stearic acid, at least one ester of stearic acid or a mixture thereof, to obtain a composition comprising 1,3-distearoyl 2-oleoyl glyceride and trioleoyl glyceride; (b) treating the composition to form a first fraction having an increased amount by weight of oleoyl groups compared to said composition and a second fraction having an increased amount by weight of stearoyl groups compared to said composition; (c) hydrolysing the first fraction to form oleic acid; and (d) reacting said oleic acid or an ester thereof with a triglyceride comprising at least 50% by moles of palmitic acid residues, based on total acyl groups, to form a composition comprising 1,3-dioleoyl 2-palmitoyl glyceride.
