Abstract
The invention relates to a method for producing an extract of a matrix of vegetable origin, particularly a plant, involving a solid-liquid extraction by means of an aqueous solution containing at least one, preferably agro-sourced, non-ionic amphiphilic compound, at a concentration at least equal to the minimum hydrotrope concentration thereof.
Claims24
A method for producing a vegetable matrix extract, comprising:
- solid-liquid extraction of a vegetable matrix with an aqueous solution comprising at least one non-ionic amphiphilic compound,
- wherein said at least one non-ionic amphiphilic compound is an alkyl polyglycoside of general formula Alk-O-Zp, wherein:
- Alk represents a saturated or unsaturated, linear or branched hydrophobic aliphatic hydrocarbon fragment having 3 to 6 carbon atoms, and
- Z represents a hydrophilic glycoside group selected from the group consisting of glucose, xylose and arabinose, and
- 1<p<5,
- wherein a concentration of the at least one non-ionic amphiphilic compound is greater than or equal to a minimum hydrotrope concentration of the at least one non-ionic amphiphilic compound, and
- wherein the at least one non-ionic amphiphilic compound does not form micelles.
