Abstract: A trough reactor, including an elongated trough shaped enclosure, a stock feed inlet, a reactant feed-in and distribution system, at least one separation plate extending downwardly underneath the elongated trough shaped enclosure and at least one separation column forming a continuous gravitational decanter with at least one outlet and a posterior outlet, as well as a method of catalyzing a reaction in a trough reactor, including horizontally inclining an elongated trough shaped enclosure, supplying a feed of substrate into the elongated trough shaped enclosure, supplying and distributing a feed-in of a reactant into the elongated trough shaped enclosure; disposing a separation plate essentially vertically in the elongated trough shaped enclosure, substantially obstructing a spontaneous gravitational flow along the elongated trough shaped enclosure by the separation plate, providing a separation column of an essentially hollow vertical structure, separating the substrate or reactant or a product by a means of

Abstract: Disclosed is an enzymatic process for the preparation of fatty acid alkyl esters, particularly fatty acids methyl esters (biodiesel) in a solvent-free microaqueous system, from a fatty acid source and an alcohol or alcohol donor, employing a robust lipase preparation that comprises at least two lipases separately or jointly immobilized on a suitable support, where one of the lipases has increased affinity to partial glycerides, another is sn-1,3 positional specific, and an optional third lipase has high selectivity towards sn-2 position of the glycerol backbone of the fatty acid source.

Abstract: The invention provides a cost-effective enzymatic process for the production of unsaturated FA esters of ascorbic acid, such as ascorbyl oleate or ascorbyl linoleate (E-304), in solvent-free system in which ascorbic acid esters of saturated FA, unsaturated free fatty acids and/or unsaturated fatty acid esters are used as feedstock. With this method pure products can even be achieved in a short response times. These products meet the needs of the industry by improving their solubility in oil and the increased antioxidant activity, especially in foods, cosmetics and medicine.

Abstract: A process for the preparation of short-chain alkyl esters of fatty acids, preferably fatty acid methyl esters (biodiesel) in solvent-free system is disclosed. In particular, the process comprises (a) providing a fatty acid source, (b) stepwise adding a short-chain free alcohol, preferably methanol, or any other alcohol donor, to said fatty acid source in the presence of a lipase preparation and (c) allowing the reaction to proceed under suitable conditions, until said fatty acid source triglycerides are converted to fatty acid methyl esters (FAME). The lipase preparation comprises at least two lipases. The two lipases being separately or jointly immobilized on a suitable support and wherein at least one of the lipases has increased affinity for partial glycerides and at least one of the lipases is sn-1,3 positional specific.
