摘要:
An aspect of the present invention relates to a method for producing cholesterol from fish oil, which generally comprises the steps of transesterifying refined oil using a basic catalyst; obtaining a stream concentrated in cholesterol and another stream concentrated in omega-3 fatty acids EPA and DHA by means of molecular distillation; and saponifying the cholesterol-rich stream using bases such as potassium hydroxide, calcium hydroxide, sodium hydroxide or calcium chloride. The mixture is subsequently saponified over a range of time and temperature, with agitation and constant reflow. Multiple extractions are carried out using solvents such as toluene, ethylene dichloride, methylene chloride, diethyl ether, petroleum ether, acetone, benzene or a hexane, and centrifugations are performed to obtain the unsaponifiable matter. This last stream is crystallised using acetone, benzene, toluene, diethyl ether, petroleum ether or a hexane to obtain cholesterol with at least 95% purity. In addition, the soap obtained from saponification is transformed into a form of ethyl ester by applying unfolding reactions and acidic esterification.

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).

摘要:
The present invention relates to a method for manufacturing soap from fatty and resin acids, in particular from tall oil fatty acid comprising resin acids. The method is based on a process in which the water conventionally utilized for saponification is partially replaced with a solvent that decreases the viscosity of the reaction mixture and results in a high dry matter content of the reaction product. An object of the invention is also a composition comprising fatty and resin acid soap and its use as a disinfectant or antiseptic agent.
