Microcapsules based on crosslinked plant polyphenols are described. These microcapsules are obtained by the interfacial crosslinking of plant polyphenols, particularly flavonoids. When incorporated in a composition such as a cosmetic, pharmaceutical, dietetic or food composition, these microcapsules make it possible to prevent any impairment of this composition, in particular any color modification, while at the same time preserving the activity, especially the anti-free radical and/or antioxidizing activity, of the plant polyphenols, particularly the flavonoids.
Des microcapsules à base de polyphénols végétaux réticulés sont décrites. Ces microcapsules sont obtenues par réticulation interfaciale de polyphénols végétaux, en particulier de flavonoïdes. Ces microcapsules, incorporées dans une composition, telle qu'une composition cosmétique, pharmaceutique, diététique ou alimentaire, permettent de prévenir toute altération, en particulier toute modificaton de la coloration de cette composition, tout en conservant l'activité des polyphénols végétaux, en particulier des flavonoïdes, notamment anti-radicalaire et/ou anti-oxydante.
