Abstract:
Process for the preparation of a lipid composition characterized by the following successive steps:(a) a mixture of lipids containing a palm oil enriched with palmitic acid, a vegetable oil high in unsaturated linoleic and alpha linoleic fatty acids, an oil which is the source of arachidonic acid, and oil which is the source of docosahexanoic acid, in defined proportions, is non-regiospecific interesterified to obtain a fatty acid composition having a random distribution of fatty acid residues between the 1-, 2-, and 3-positions of triacylglycerol,(b) the composition of step (a) is interesterified with a mixture of free fatty acids predominantly comprising medium-chain fatty acids and oleic acid, using a 1,3-regiospecific lipase, and(c) excess free fatty acids are removed from the composition first by partial deacidification with steam distillation under vacuum, and then by controlled neutralization of the partially deacidified composition.
