The present invention provide an anti-fading agent for a pigment, characterized by comprising as active ingredients at least one oligosaccharide selected from the group consisting of nigerooligosaccharide, maltooligosaccharide and panose, when so required, in addition of an antioxidant. The anti-fading agent of the invention can advantageously inhibit fading in colors (including fading in colors by light irradiation and heat treatment) of natural pigments such as anthocyanin-based pigments, flavonoid-based pigments, carotenoid-based pigments and the like, and is useful for colored beverage and food products, pharmaceutical drugs, cosmetics and the like with which the fading in colors may be a problem.

Method for inhibiting fading of a natural pigment using nigerooligosaccharide or maltooligosaccharide or panose with or without an antioxidant

Disclosed is a water-soluble color-stabilized food containing ascorbic acid or its salt and at least one water-soluble color selected from the group consisting of coal-tar color, anthocyanin color and carthamus yellow, said food further containing sorbic acid and/or its salt and/or a salt of sulfurous acid so that the fading of the water-soluble color can be prevented and the stability thereof can be increased.
