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.
