Abstract:
Process for the extraction of an active principle with anti-radical and anti-glycolation activity to counter cutaneous aging, characterized in that it comprises the following steps:crushing sunflower seeds to obtain on the one hand an oil and on the other hand a de-oiled flour,aqueous solubilization of this obtained flour, in an amount of 10 to 40% by volume,hydrolysis of the proteins in the presence of a protease of acid pH,separation of the soluble and insoluble phases,inactivation of this hydrolyzed solution at a pH comprised between 2.0 and 8.0 at a temperature at least equal to 45.degree. C.,filtration to purify the active molecules, andsterilizing filtration on a membrane so as to limit the presence of microorganisms, of total mesophilic flora, of yeasts, and of molds.
