Abstract
The present invention relates to a composition containing a quinoa grain extract, said extract being a peptidic and osidic extract or a lipidic extract of quinoa grain, said lipid quinoa extract being itself chosen from a group comprising an oil concentrated into its non saponificable fraction, a non saponificable, or a refined oil. The invention also relates to methods for preparing these different extracts and to dermatological or neutraceutic applications of these extracts.

A method for preparing a quinoa peptide and oside extract, comprising the following successive steps:
- a) starting with quinoa grains, extraction of a raw oil and of a cake and recovery of said cake;
- b) washing said recovered cake with water or with a water/alcohol mixture in order to only retain a protein portion, and then
- c) solubilizing the proteins;
- d) concentrating the proteins and then hydrolyzing said proteins into peptides;
- e) purifying and recovering the peptide extract.
A method for preparing quinoa oil concentrated in its unsaponifiable fraction, comprising a step for molecular distillation of a refined quinoa oil.
A method for preparing a quinoa unsaponifiable, comprising a step for saponifying a quinoa oil concentrated in its unsaponifiable fraction, and then extracting this unsaponifiable with a suitable solvent.
A method of using a quinoa extract, selected from a quinoa peptide extract or a quinoa lipid extract, wherein said quinoa lipid extract is selected from the group consisting of an oil concentrated in its unsaponifiable fraction, an unsaponifiable or a refined oil having the following specifications:
