    • Processes for preparing conjugated fatty acid glycerides comprising: (a) isomerizing a fatty acid lower alkyl ester corresponding to the general formula (I) in the presence of a basic catalyst at a temperature of from 100 to 160° C., to form a conjugated fatty acid lower alkyl ester: R1CO—OR2  (I) wherein R1CO represents an acyl radical having from 16 to 22 carbon atoms and at least two carbon-carbon unsaturations and R2 represents an alkyl radical having from 1 to 4 carbon atoms; and (b) transesterifying the conjugated fatty acid lower alkyl ester with glycerol to form a conjugated fatty acid glyceride, wherein a lower alkanol corresponding to the general formula R2OH is formed, wherein R2 is as defined above, and the lower alkanol is continuously removed from the transesterification reaction; are described.

    • The present invention relates to a method for working up a mixture which contains esters of EPA and/or DHA with monohydric alcohols having 1 to 6 carbon atoms, esters of other fatty acids with monohydric alcohols having 1 to 6 carbon atoms, and free cholesterol, wherein the method comprises adding a transesterification catalyst to the mixture, converting at least some of the free cholesterol into esterified cholesterol and thereafter distilling the mixture, wherein the distillation is carried out in such a manner that a product is obtained which contains EPA and/or DHA, both in the form of esters thereof with monohydric alcohols having 1 to 6 carbon atoms, in a higher relative amount, based on all fatty acids in free or bound form present in the product, than said mixture. In addition, the present invention relates to a product which is obtainable by the method according to the invention, wherein the product contains 10 to 99.99% by weight of esters of EPA and/or of DHA with monohydric alcohols having 1 to 6 carbon atoms and 0.0001 to a maximum of 0.3% by weight of cholesterol in free or bound form.
    • 本发明涉及一种用于处理含有EPA和/或DHA的酯与具有1至6个碳原子的一元醇的混合物的混合物的方法,其它脂肪酸与具有1至6个碳原子的一元醇的酯和游离胆固醇, 其中所述方法包括向所述混合物中加入酯交换催化剂,将至少一些游离胆固醇转化为酯化胆固醇,然后蒸馏混合物,其中蒸馏是以获得含有EPA和/或 DHA,以其与具有1至6个碳原子的一元醇的酯的形式,以相对于所述混合物中存在的游离或结合形式的所有脂肪酸的相对量较高。 另外本发明涉及通过本发明的方法获得的产品,其中该产品含有10至99.99重量%的EPA和/或DHA的酯与具有1至6个碳原子的一元醇的酯和 0.0001至最大0.3重量%的游离或结合形式的胆固醇。
