Abstract: Disclosed is a process for producing a composition involving: (a) distilling fish oil in a vacuum distillation column to obtain a first residue and first distillate, and (b) distilling the first distillate in a vacuum distillation column to obtain a second distillate and a second residue that includes a composition containing cholesterol, eicosapentaenoic acid, and docosahexaenoic acid. Also disclosed is a process for producing a composition involving: (a) distilling fish oil in a vacuum distillation column to obtain a first residue and first distillate, (b) distilling the first distillate in a vacuum distillation column to obtain a second distillate and second residue containing cholesterol, (c) esterifying the second residue to obtain a mixture containing cholesterol esters, and (d) distilling the mixture in a vacuum distillation column to obtain a third distillate and a third residue that includes a composition containing cholesterol esters of eicosapentaenoic acid and docosahexaenoic acid.

Abstract: Disclosed is a process for producing a cholesterol concentrate including the steps of (a) distilling a fish oil having no more than 2% free fatty acids in an admixture with an auxiliary fluid in a vacuum distillation column to obtain a first distillate and a first residue; and (b) distilling the first distillate in a vacuum distillation column to obtain a second distillate and a second residue, wherein the second residue includes the cholesterol concentrate.

Abstract: The current invention describes processes for obtaining of concentrates of esters of eicosapentaenoic acid and docosahexaenoic acid for their use in massive and regular human consumption either as a pharmaceutical ingredient or as a food ingredient, which are characterized by having neutral and stable organoleptic properties, free of side effects, which are typical from marine oils derivatives, and with low content of Persistent Organic Pollutants (POP).

Abstract: An efficient and simple process to obtain a concentrate that includes over 80% in weight of ethyl esters of ?-3 fatty acids based on a composition of matter that contains esters of ?-3 fatty acids or free ?-3 fatty acids that comprises the stages of: a) contacting the composition of matter with ethanol of at least 96% in weight and a hydroxide of an alkali metal at a temperature between 60 and 200° C. to form a liquid mixture that includes alkaline salts of fatty acids; b) cool the liquid mixture to a temperature between 50 and ?20° C. to form a solid phase and a liquid phase and separate the liquid phase from the solid phase; c) contact the separated liquid phase of stage b) with an acid to form an acidified mixture with a water content under 10%, where the mixture consists of a solid phase that includes the alkali metal salt of the acid and a liquid phase that comprises ?-3 fatty acids; d) heat the mixture of stage c) between 50 to 150° C.
