Abstract: The present disclosure describes that high purity cholesterol is obtained by the processes of the invention without any further purification step, such as a crystallizing step from a solvent, but rather by distilling steps alone. The disclosures provides a process that includes the production of compositions having a cholesterol content over 75% in weight, from fish oil processing waste residues.

Abstract: Disclosed is a process for producing cholesterol from fish oil, including the following steps: (a) distilling fish oil in a vacuum distillation column to obtain a first residue and a first distillate, (b) distilling the first distillate in a vacuum distillation column to obtain a second distillate and a second residue, (c) contacting the second residue with an alkali to produce a saponified mixture, (d) contacting the saponified mixture with a non-polar organic solvent or a mixture of non-polar organic solvents to produce an organic phase and an aqueous phase, (e) separating the organic phase from the aqueous phase, (f) cooling the organic phase to form a solid phase and a liquid phase, and (g) separating the solid phase from the organic phase, wherein the separated solid phase includes cholesterol.

Abstract: The invention relates to a method for the production of highly stable aqueous dispersions of phytosterols, phytostanols and derivatives thereof, which allows the use of a wide range of emulsifiers in relatively small concentrations in relation to the phytosterols and which allows the preparation of dispersions with high concentrations of phytosterols. Said dispersions are obtained using a method in which one or more phytosterols, an aqueous medium and one or more emulsifiers are dispersed in a disperser at a temperature of at least 140° C. in order to obtain an emulsion and the resulting emulsion is subsequently cooled in order to obtain a dispersion of sterols in an aqueous medium.

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.

Abstract: Carrier fluid compositions and their use in processes for reducing the concentration of persistent organic pollutants, such as polychlorodibenzo-p-dioxins (PCDDs), polychlorodibenzo-p-furans (PCDDF), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), and pesticides, such as chlorinated hydrocarbons, chlorinated toxaphenes and camphenes, in fish oil are disclosed. The process includes vacuum distillation of the fish oil in the presence of the carrier fluid compositions to provide a fish oil residue having a reduced concentration of persistent organic pollutants.
