摘要：The present invention relates to a method for working up a mixture whichcontains 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 freecholesterol, wherein the method comprises adding a transesterification catalyst to themixture, converting at least some of the free cholesterol into esterified cholesterol andthereafter distilling the mixture, wherein the distillation is carried out in such a mannerthat a product is obtained which contains EPA and/or DHA, both in the form of estersthereof 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. Inaddition, the present invention relates to a product which is obtainable by the methodaccording to the invention, wherein the product contains 10 to 99.99% by weight ofesters of EPA and/or of DHA with monohydric alcohols having 1 to 6 carbon atoms and0.0001 to a maximum of 0.3 % by weight of cholesterol in free or bound form.
