Abstract: The present invention relates to a process for preparing esters from fatty alcohols, in which fatty alcohols and fatty acids are reacted in the presence of an enzyme at a temperature in the range of 30 to 50° C., the water which forms is removed and the reaction is completed under reduced pressure at a temperature of 50 to 80° C.

Abstract: Described are alkoxylated glycerol acetals according to Formulas (Ia) and (Ib) wherein R1 represents a linear or branched, saturated or unsaturated and optionally substituted hydrocarbyl residue comprising 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, a benzyl or furfuryl radical, R2 is selected from hydrogen, an alkyl, alkenyl or hydroxyalkyl group having 6 to 22 carbon atoms or an acyl group having 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, AO represents an ethylene oxide, a propylene oxide, a butylene oxide unit, or their mixtures, and n is an integer of about 1 to about 100.

Abstract: The invention relates to a process for production of fatty acids directly from soapstock generated in the alkali refining process including the steps of (a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of glycerides without prior neutralization, (b) neutralizing and splitting the soaps with strong acids, and (c) separating the fatty acid phase from the aqueous phase by settling and/or centrifugation. A second embodiment is a process in which the soapstock is first neutralized and split with strong acids, followed by adding a lipase to facilitate glyceride hydrolysis, and separating the fatty acid phase. The fatty acids so obtained can be esterified with C1-C6 alcohols using a lipase that is selective for fatty acids and does not transesterify the sterolesters, and the fatty acid esters and sterolesters are separated by distillation. The sterolesters are useful as supplements for food, as pharmaceutical agents for lowering cholesterol and as biofuel and biodiesel.

Abstract: A higher-yielding process for the production of monoglycerides in which triglycerides are enzymatically reacted with a catalytic amount of an esterase, preferably lipase, that has been activated by the addition of alkaline salts, in the presence of linear or branched alcohols containing 1 to 8 carbon atoms, then the esterase may be deactivated and it and the remaining alcohol removed, with the monoglycerides thus produced useful in lubricants, fuel additives, and emulsifying constituents in foods, and cosmetic and/or pharmaceutical formulations.

Abstract: Disclosed are novel lipophilic preparations comprising (a) from 20 to 40% by weight of myristic acid or esters thereof, (b) from 20 to 40% by weight of palmitic acid or esters thereof, (c) from 0.1 to 5% by weight of aliphatic and/or cycloaliphatic hydrocarbons and (d) less than 20% by weight of carboxylic acids or esters thereof having 12 and fewer carbons in the acyl moiety and (e) less than 20% by weight of carboxylic acids or esters thereof having 16 and more carbons in the acyl moiety, with the proviso that all percentages add up to 100% by weight.

Abstract: A composition comprising alkyl esters, with a C1-C8 alkyl 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 C8-C22 fatty 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.

Abstract: A chemoenzymatic process for the production of fatty acid esters comprising partially esterifying one or more fatty acid esters, under mild temperatures with an enzymatic catalyst, and optionally in the presence of one or more inert solvents, with a 1- to 5-fold molar excess of one or more water-containing aliphatic alcohols with boiling points between 60° C. and 120° C., then removing the water and unreacted alcohol(s) from the resulting pre-esterification product, followed by additional esterification up to 99.7%, chemically-catalyzed with, e.g., an acid or tin salt at slightly higher temperatures, optionally using one or more inert solvents, with a 1- to 4-fold molar excess of the same one or more aliphatic alcohols as employed in the preliminary esterification step.

Abstract: A process for enriching and separating polyunsaturated fatty acid (PUFA) acyl groups in a fatty acid mixture, which mixture contains other non-PUFA fatty acid acyl groups, is disclosed.
