The present invention refers to a process for reducing the amount of undesired components in an oil composition, particularly in an oil composition comprising omega-3 polyunsaturated fatty acids. The process of the present invention provides efficient removal of undesired water-soluble (hydrophilic) components and undesired fat-soluble (lipophilic) components from an oil composition in order to obtain a purified concentrate, e.g. a highly purified concentrate enriched in omega-3 polyunsaturated fatty acids.

Removal of undesired components from oil compositions

The present disclosure relates generally to processes for concentrating omega-3 fatty acids from a fatty acid oil mixture with an aqueous silver salt, such as an aqueous AgNOsolution.

Process for concentrating omega-3 fatty acids

The present invention relates to a process for preparing compositions of high concentrations of omega-3 fatty acids from krill. Furthermore, the invention relates to a composition comprising high concentrations of omega-3 fatty acids, and a lipid fraction from krill comprising high amounts of fatty acids with chain length C14 and C16.

The invention relates to a process for decreasing the amount of environmental pollutants in a mixture comprising a fat or an oil, being edible or for use in cosmetics, the fat or oil containing the environmental pollutants, which process comprises the steps of adding a volatile working fluid to the mixture, where the volatile working fluid comprises at least one of a fatty acid ester, a fatty acid amide, a free fatty acid and a hydro-carbon, and subjecting the mixture with the added volatile working fluid to at least one stripping processing step, in which an amount of environmental pollutant present in the fat or oil, being edible or for use in cosmetics, is separated from the mixture together with the volatile working fluid. The present invention also relates to a volatile environmental pollutants decreasing working fluid, for use in decreasing an amount of environmental pollutants present in a fat or oil, being edible or for use in cosmetics. In addition, the present invention relates to a health supplement, a pharmaceutical and an animal feed product prepared according to the process mentioned above.

Pharmaceutical composition comprising low concentrations of environmental pollutants

The invention relates to a process for decreasing the amount of environmental pollutants in a mixture comprising a fat or an oil, being edible or for use in cosmetics, the fat or oil containing the environmental pollutants, which process comprises the steps of adding a volatile working fluid to the mixture, where the volatile working fluid comprises at least one of a fatty acid ester, a fatty acid amid, a free fatty acid and a hydro-carbon, and subjecting the mixture with the added volatile working fluid to at least one stripping processing step, in which an amount of environmental pollutant present in the fat or oil, being edible or for use in cosmetics, is separated from the mixture together with the volatile working fluid. The present invention also relates to a volatile environmental pollutants decreasing working fluid, for use in decreasing an amount of environmental pollutants present in a fat or oil, being edible or for use in cosmetics. In addition, the present invention relates to a health supplement, a pharmaceutical and an animal feed product prepared according to the process mentioned above.

Process for decreasing environmental pollutants in an oil or a fat

The invention relates to a process for decreasing the amount of cholesterol in a mixture comprising a marine oil, the marine oil containing the cholesterol, which process comprises the steps of adding a volatile working fluid to the mixture, where the volatile working fluid comprises at least one of a fatty acid ester, a fatty acid amide and a hydrocarbon, and subjecting the mixture with the added volatile working fluid to at least one stripping processing step, in which an amount of cholesterol present in the marine oil in free form is separated from the mixture together with the volatile working fluid. The present invention also relates to a volatile cholesterol decreasing working fluid and a health supplement and a pharmaceutical, based on a marine oil, prepared according to the process mentioned above.

Process for decreasing the amount of cholesterol in a marine oil using a volatile working fluid

Marine oil compositions which contain EPA and DHA as free acids or hexyl esters are esterified with ethanol in the presence of a lipase catalyst under essentially organic solvent-free conditions and separated by distillation.

Lipase-catalysed esterification of marine oil

Marine oil compositions which contain EPA and DHA as free acids are esterified with glycerol in the presence of a lipase catalyst under reduced pressure and essentially organic solvent-free conditions to form a free fatty acid fraction enriched in at least one of EPA and DHA.
