    • 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 fromUlkenia 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). The invention also relates to the fatty acid composition obtainable according to the inventive method and to the use thereof.
    • 本发明涉及一种脂肪酸组合物的制造方法,该脂肪酸组合物基于脂肪酸组合物中含有的脂肪酸和/或脂肪酸衍生物的总重量含有至少70.0重量%的二十二碳六烯酸和/或二十二碳六烯酸 烷基酯。 本发明的方法包括以下步骤:a)将从不锈菌获得的生物质酯交换 由此产生至少一种二十二碳六烯酸烷基酯和至少一种饱和脂肪酸酯,b)产生含有脲,至少一部分来自步骤a)和至少一种有机溶剂的生物质的溶液,c) 冷却或浓缩步骤b)的溶液,从而产生i)含有尿素和至少一部分饱和脂肪酸酯的沉淀物,和ii)液体馏分,以及d)将沉淀物i)与液体馏分 ⅱ)。 本发明还涉及根据本发明方法可获得的脂肪酸组合物及其用途。
