Abstract
The sunlight stability of anthocyanic pigments in mixtures, especially foods, may be enhanced by including in the mixture a photoprotective agent selected from the group consisting of sulfonated polyhydroxyflavonols, poly(hydroxyalkyl) flavonols, sulfonated polyhydroxyflavones, sulfonated polyhydroxyiso-flavones, and sulfonated aurones.
Claims27
A process for the production of a photostable anthocyanic colorant composition comprising combining an anthocyanic pigment and a photoprotective agent selected from the group consisting of sulfonated polyhydroxyflavonols, poly(hydroxyalkyl)flavonols, sulfonated polyhydroxyflavones, sulfonated polyhydroxyiso-flavones, and sulfonated aurones, the molar ratio of said photoprotective agent to said anthocyanic pigment being not less than 1:1.
A photostable anthocyanic colorant composition consisting essentially of an anthocyanic pigment in combination with a photoprotective agent selected from the group consisting of sulfonated polyhydroxyflavonols, poly(hydroxyalkyl)flavonols, sulfonated polyhydroxyflavones, sulfonated polyhydroxyiso-flavones and sulfonated aurones said photoprotective agent being present in a molar concentration at least as great as the molar concentration of said anthocyanic pigment.
A food composition consisting essentially of a food base, an anthocyanic pigment and a photoprotective agent selected from the group consisting of poly(hydroxyalkyl)flavonols, sulfonated polyhydroxyflavones, sulfonated polyhydroxyisoflavones, sulfonated polyhydroxyflavonols, and sulfonated aurones.
