Abstract

The invention relates to structured lipid mixtures corresponding to formula (I): characterized in that R1CO, R2CO and R3CO independently of one another represent (i) linear saturated acyl groups containing 6 to 12 carbon atoms or (ii) the acyl group of conjugated linoleic acid (CLA) and/or an omega-3 or omega-6 fatty acid (OF), with the proviso that the quantity of CLA acyl groups amounts to 3 to 50 mol- % and the quantity of OF acyl groups to 5 to 25 mol- %, based on the quantity of acyl groups. The mixtures are preferably made by subjecting a mixture of component (a) a medium-chain triglyceride; and component (b) a CLA, an (OF), a TG-CLA (TG-OF) or a mixture thereof to enzymatic transesterification in the presence of a vegetable, marine or microbial oil.

Dependent claims

A process for the production of structured lipid mixtures corresponding to formula (1):

in which R1CO, R2CO and R3CO, 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 R4CO, R5CO and R6CO, 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.

(a) mixtures of fatty acids or esters of fatty acids corresponding to formula (III):
R7COOR8 (III)
in which R7CO is a linear saturated acyl group containing 6 to 12 carbon atoms and R8 is hydrogen or an alkyl group containing 1 to 4 carbon atoms, and, optionally, glycerol, and
(b) conjugated linoleic acid (CLA) and/or omega-3 and/or omega-6 fatty acids, wherein component (a) and component (b) or their triglycerides are present in the reaction mixture in a molar ratio of 1:1 to 20:1, based on fatty acid equivalents.
