Abstract: A process for increasing the concentration of PUFA triglycerides present in natural PUFA oils, in which a natural PUFA oil having a triglyceride content of more than 85% by weight, based on the total weight of the mixture, and having a total PUFA content of more than 39% by weight of total fatty acids is dissolved in an organic solvent or an organic solvent mixture, the mixture is allowed to stand at a temperature of from ?35° C. to ?100° C. for a period of more than five minutes, the mixture is separated into a supernatant comprising PUFA-triglyceride mixture and a sediment phase, the separation preferably taking place by filtration or centrifugation, and the solvent or solvent mixture, after the removal of the sediment phase, is separated from the supernatant.

Abstract: The invention relates to a method for the fermentative production of lipids/fatty acids having high concentrations of omega-6 fatty acids (PUFA, polyunsaturated fatty acids), especially ?-linolenic acids (GLA) in ciliates. Said lipids/fatty acids can be used in human/animal food, and in the pharmaceutical field.

Abstract: The invention relates to an antioxidant extract from Crypthecodinium sp. The invention also relates to a fatty acid composition which comprises at least one unsaturated fatty acid and/or at least one unsaturated fatty acid ester and at least one extract according to the invention and constituents of a biomass different from Crypthecodinium sp., to a method for producing the fatty acid composition and to its use.

Abstract: The invention relates to a method for producing a fatty acid composition which, based on the entire weight of the fatty acids and/or fatty acid derivatives contained in the fatty acid composition, contains at least 70.0% by weight of docosahexaenoic acid and/or docosahexaenoic alkyl ester. The inventive method comprises the following steps: a) transesterifying a biomass obtained from Ulkenia sp. with an alcohol, thereby producing at least one docosahexaenoic alkyl ester and at least one saturated fatty acid ester, b) producing a solution which contains urea, at least a part of the biomass from step a) and at least one organic solvent, c) cooling or concentrating the solution from step b), thereby producing i) a precipitate which contains urea and at least a part of the saturated fatty acid esters, and ii) a liquid fraction, and d) separating the precipitate i) from the liquid fraction ii).

Abstract: The present invention relates to a method for producing a saturated organic compound bearing at least one functional group from a mixture which comprises this saturated organic compound containing at least one functional group and also one or more other organic compounds, which comprises i) mixing a silver-ion-loaded ion exchanger with the mixture at a temperature which is below the boiling point of the mixture, ii) then removing the supernatant and iii) detaching the ion-exchanger-bound, saturated organic compound having at least one functional group from the ion exchanger.

Abstract: The invention relates to a novel extraction method for obtaining at least one unsaturated, optionally derivatized compound, from mixtures of said compounds with other less saturated constituents, e.g. for obtaining polyunsaturated fatty acids or the derivatives thereof from mixtures with saturated and/or less unsaturated, optionally derivatized fatty acids, by means of selective complexation with a cation exchanger which is partially or fully charged with silver ions, and subsequent decomplexation.

Abstract: The invention relates to a method for obtaining fatty acid esters and fatty acids, preferably unsaturated fatty acid ethyl esters, from biological sources by continuous, combined in-situ extraction, reaction and chromatography. The invention is characterized in that simultaneously and in the same location, in the presence of a compressed gas and an 0.5-5 % stream of lower alcohols as modifiers and in the presence of an inert catalyst, the fatty acids are fully transesterified from their native fatty acid sources, which are selectively desorbed and eluated in the conditions specified above.
