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 pre-sent 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.
L'invention porte sur un procédé permettant de réduire la quantité de polluants environnementaux présents dans des mélanges comprenant des graisses ou des huiles à usage alimentaire ou cosmétique. Ledit procédé comporte les étapes suivantes: adjonction au mélange d'un fluide de travail volatile comprenant l'un au moins d'un ester d'acide gras, d'un amide d'acide gras, d'un acide gras libre et d'un hydrate de carbone; puis au moins une étape d'épuisement où la quantité de polluants environnementaux présents dans les graisses ou huiles à usage alimentaire ou cosmétique est séparée du mélange en même temps que le fluide de travail volatile. L'invention porte également sur un fluide de travail réduisant les polluants environnementaux volatiles présents dans des graisses ou huiles à usage alimentaire ou cosmétique. L'invention porte en outre sur un supplément de santé et sur un produit pharmaceutique et sur un produit alimentaire pour animaux, préparés au moyen du susdit processus.
