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.

The invention relates to a wet grinding method for producing sterol formulations having good wettability. According to said method, a) an additive selected from the group consisting of proteins, proteinaceous adjuvants, carbohydrates, cellulose derivatives, sugar alcohols, fruit concentrates and vegetable concentrates is dissolved or dispersed in water or in an aqueous suspension medium, b) sterol and/or stanol particles having a median particle size of at least 1 mm are added to this solution/dispersion, c) the dispersion thus obtained is homogenized and size-reduced in a mill that works according to the rotor/stator principle, and d) is then optionally dried, with the proviso that the sterol and/or stanol particles are present in the final formulation with a particle size distribution of Dof not more than 50 &#x3bc;m. Owing to their good wettability, the sterol-containing formulations produced according to this method can be incorporated into food items without complex technology and have good organoleptic and sensory properties especially when used in drinks and dairy products.
