Processes for the enzyme-catalyzed production of triglycerides using polyunsaturated fatty acids, in which (a) the reaction of polyunsaturated fatty acids and/or Calkyl esters thereof with glycerol in vacuo in the presence of an immobilized enzyme to form their triglycerides is accelerated by addition of an additive from the group of weakly basic salts, complexing agents and ion exchangers and/or addition of a weakly basic salt and/or addition of an entraining agent in the form of a solvent or a gas and/or addition of glycerol-binding adsorbers and/or heat treatment of the partial glyceride intermediate product, (b) the immobilized enzymes are removed from the triglyceride by separation or filtration and (c) the remaining fatty acids and/or Calkyl esters thereof are removed from the triglyceride by distillation, refining or extraction.

A composition comprising alkyl esters, with a C-Calkyl group, and partial glycerides, with a free glycerol content of, at most, 2%, by weight, based on the weight of the composition, derived in an enzymatically-catalyzed reaction from saturated or unsaturated, straight or branched C-Cfatty acids of vegetable oils, and useful, inter alia, in biofuels, such as biodiesel, and as an additive for improving the lubricating performance of fuel compositions.

Compositions which can be used as biofuel

The invention relates to structured lipid mixtures corresponding to formula (I): characterized in that RCO, RCO and RCO independently of one another represent

Process for the production of structured lipid mixtures

Processes for preparing conjugated linoleic acid are described wherein a conjugated linoleic acid lower alkyl ester is subjected to hydrolysis in the presence of an enzyme to form a hydrolyzate comprising a conjugated linoleic acid and a lower alkanol, wherein at least a portion of the lower alkanol is continuously removed; the hydrolyzate is separated into an organic phase and an aqueous/alcoholic phase; and the conjugated linoleic acid is separated from the organic phase.
