Abstract
The invention concerns a method for extracting and fractionating fats contained in a raw material, characterized 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): CnF2n+1OCmH2m+1, wherein: n ranges between 3 and 6 and m ranges between 1 and 5 and at least a separation step enabling to obtain a raw extract of fats rich in unsaponifiable substances and optionally, in free fatty acids and a insoluble extraction fraction.
Claims20
A method of extraction and fractionation of fatty material from a raw material,
- characterized in that it comprises at least one extraction step using an extraction solvent formed by at least a hydrofluoroether with general formula:
- CnF2n+1OCmH2m+1
- in which n is between 3 and 6 and in is between 1 and 5 and at least one separation step leading to obtaining crude extract of fatty material rich in unsaponifiable substances, and possibly free fatty acids, and an insoluble extraction fraction.
