Abstract
The invention relates to a method for producing an extract of a matrix of vegetable origin, particularly a plant, characterised in that the matrix of vegetable origin undergoes a mechanical treatment consisting in extruding the matrix of vegetable origin in an extruder, in association or not with a heat treatment, in the presence of an aqueous solution containing at least one hydrotrope agent, particularly at a concentration at least equal to the minimum hydrotrope concentration thereof, followed by an operation of recovering the extract.
Claims16
A method for obtaining an extract of a vegetable matrix, wherein the vegetable matrix is a plant matrix, characterized in that the vegetable matrix is subjected to mechanical treatment consisting of extruding the vegetable matrix in an extruder, associated or not with heat treatment, in the presence of an aqueous solution containing at least one hydrotropic agent, followed by an operation to recover the extract,
- wherein the hydrotropic agent is an alkyl-(poly)glycoside of general formula Alk-O-Zp, where:
- Alk designates a hydrophobic, aliphatic hydrocarbon fragment, saturated or unsaturated, straight-chain or branched, having 3 to 7 carbon atoms, and
- Z is a hydrophilic glycoside group selected from the group consisting of glucose, xylose and arabinose, and 1<p<5.
