EXTRACTION AND FRACTIONATION METHOD OF FATTY MATERIAL BY A SOLVENT USING AT LEAST A HYDROFLUOROETHER

摘要

The invention concerns a method for extracting and fractionating fats contained in a raw material, characterised in that it comprises at least a step which consists in using an extraction solvent consisting of at least a hydrofluoroether of general formula (I): CnF 2n+1 O Cm H2m+1, wherein: n ranges between 3 and 6 and m ranges between 1 and 5 and at least a separatio n step enabling to obtain a raw extract of fats rich in unsaponifiable substances and optionally, in free fatty acids and a insoluble extraction fraction.
