  • Patent number: 8889895
    Abstract: 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.

  • Publication number: 20130292242
    Abstract: The present invention relates to an apparatus for the distillation of substance mixtures which comprise temperature-sensitive substances, where the apparatus comprises a thin-film evaporator and a fractionating column, and where the fractionating column is attached to the distillate outlet of the thin-film evaporator, and where the fractionating column has at least 3 theoretical plates, and where the pressure drop of the fractionating column during operation at an F factor of 1 Pa1/2 amounts to a maximum of 3 hPa (3 mbar). Furthermore, the present invention relates to a process for the distillation of substance mixtures which comprise temperature-sensitive substances, which process is carried out in the apparatus according to the invention.

  • Patent number: 8414945
    Abstract: 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 D90% of not more than 50 ?m.

  • Publication number: 20100055190
    Abstract: The invention relates to a powder formulation containing sterol in the form of a super-cooled melt from sterols and sterol esters, provided that the sterol ester content is at least 30 wt % in relation to the content of the powder. The introduced sterol ester is a fatty acid ester having a chain length of 2 to 24, preferably 8 to 12 carbon atoms. As the sterol preparations are wettable and melt easily without the use of complex equipment, they can easily be incorporated into food, and produce, in particular, good organoleptic and sensory properties, in particular, in drinks.

  • Publication number: 20100021525
    Abstract: The invention relates to a method for producing coated sterol powders. According to said method, a) micronized sterol and/or stanol particles are provided in a mixer, b) the micronized sterol and/or stanol particles are wetted with a proteinaceous aqueous solution/dispersion, c) the wetted particles are mixed well and then dried, and d) the dried mixture is optionally size-reduced in a mill. Owing to their good wettability, the sterol-containing formulations produced according to this method can be incorporated into food items without technical complications and have good organoleptic and sensory properties especially when used in drinks and dairy products.

  • Publication number: 20090099146
    Abstract: The invention relates to sterol fatty acid esters of average chained fatty acids, having a chain length of 8 and 10 carbon atoms in a fatty acid distribution C8 to C10 (weight ratio) from 95:5 to 5:95, preferably, fatty acid distributions of C8 to C10 (weight ratio) from 90:10 to 20:80 and in particular, distributions of the fatty acids C8 to C10 (weight ratio) from 64:36 to 50:50 or from 78:22 to 65:35, are used. Preferably, capric and/or caprylic acids are used as fatty acids. Said sterol compounds can be easily incorporated into food, in particular, into drinks and milk products based on their wettability and easy to melt properties at low temperatures without using complex equipment, and have good organolepetic and sensory properties, and improved stability in relation to commercial sterol esters having long-chained and unsaturated fatty acids.
