Patent ID: 7604966

Claim:
A process for the production of structured lipid mixtures corresponding to formula (1): in which R 1 CO, R 2 CO and R 3 CO, independently of one another, are selected from the group consisting of (i) a linear saturated acyl group containing 6 to 12 carbon atoms, (ii) an acyl group of conjugated linoleic acid (CLA), (iii) an acyl group of an omega-3 fatty acid (OF), and (iv) an acyl group of an omega-6 fatty acid (OF), with the proviso that the quantity of CLA acyl groups amounts to 3 to 50 mol- % and/or the quantity of OF acyl groups amounts to 5 to 25 mol- %, based on the quantity of acyl groups, said process comprising subjecting a reaction mixture of components (a) and (b) to transesterification in the presence of one or more microbial lipases and also in the presence of one or more vegetable, marine or microbial oils or mixtures thereof, wherein components (a) and (b) are: (a) a medium-chain triglyceride (MCTs) corresponding to formula (II): where R 4 CO, R 5 CO and R 6 CO, independently of one another, stand for a linear saturated acyl group containing 6 to 12 carbon atoms, and (b) a conjugated linoleic acid (CLA), an omega-3 fatty acid (OF), an omega-6 fatty acid (OF), a triglyceride based on conjugated linoleic acid (TG-CLA), an omega-3 (TG-OF) or an omega-6 fatty acid (TG-OF), and a mixture thereof, wherein component (a) and component (b), respectively, are present in the reaction mixture in a molar ratio of 1:1 to 20:1, based on fatty acid equivalents.
