摘要

The invention relates to a process for decreasing the amount of environmental pollutantsin a mixture comprising a fat or an oil, being edible or for use in cosmetics, thefat or oil containing the environmental pollutants, which process comprises thesteps of adding a volatile working fluid to the mixture, where the volatile workingfluid comprises at least one of a fatty acid ester, a fatty acid amide, a free fattyacid and a hydro-carbon, and subjecting the mixture with the added volatile workingfluid to at least one stripping processing step, in which an amount of environmentalpollutant pre-sent in the fat or oil, being edible or for use in cosmetics, is separatedfrom the mixture together with the volatile working fluid. The present inventionalso relates to a volatile environmental pollutants decreasing working fluid,for use in decreasing an amount of environmental pollutants present in a fat oroil, being edible or for use in cosmetics. In addition, the present inventionrelates to a health supplement, a pharmaceutical and an animal feed product preparedaccording to the process mentioned above.
