Fading inhibitors for pigments characterized by containing at least one oligosaccharide selected from the group consisting of nigerooligosacchride, maltooligosaccharide and panose optionally together with an antioxidant. These fading inhibitors can significantly prevent natural pigments (in particular, anthocyanin pigments, flavonoid pigments, carotenoid pigments, etc.) from fading (involving fading caused by light irradiation or heating). Thus, they are useful as fading inhibitors in colored foods and drinks, drugs, cosmetics and the like suffering from the problem of fading.

La présente invention concerne des inhibiteurs de décoloration de pigments, caractérisés en ce qu'ils contiennent au moins un oligosaccharide sélectionné dans le groupe comprenant nigéro-oligosaccharide, malto-oligosaccharide et panose, éventuellement associés à un antioxydant. Ces inhibiteurs de décoloration peuvent sensiblement empêcher la décoloration (y compris la décoloration due au rayonnement lumineux ou au chauffage) des pigments naturels (en particulier les anthocyanines, les flavonoïdes, les caroténoïdes, etc.). En l'occurrence, on peut utiliser ces inhibiteurs de décoloration dans les boissons et aliments colorés, les médicaments, les produits cosmétiques et analogues, qui présentent des problèmes de décoloration.
