Abstract
The invention relates to a process for the fractionation of seeds of oleaginous plants of to the Asteraceae family, comprising at least one mechanical pressing operation of the seeds and an extraction with polar organic solvent of the first residue obtained. Said process allows to separate oil, active substances and a solid residue which is particularly suitable to be used in animal feed. The present invention also relates to said solid residue and to its use for the production of animal feed, as well as to the extracted active substances and to their use as cosmetic and/or pharmaceutical ingredient.
Claims22
A process for the fractionation of seeds of an oleaginous plant of the Asteraceae family into oil, solid residue and active substances comprising the steps of:
- (a) subjecting said seeds to at least one mechanical pressing operation, removing at least a portion of the oil and obtaining a first residue;
- (b) subjecting said first residue to extraction with a polar organic solvent and separating the remaining solid residue from the resulting liquid phase comprising oil and extracted active substances;
- (c) separating the active substances and oil from said liquid phase of step b),
- wherein the extraction of step b) is performed at temperatures above ambient temperature and below or equal to the boiling point of the solvent and wherein the weight ratio between the polar organic solvent and the first residue is from 1:1 to 4:1.
