Abstract
Disclosed herein is a process for reducing the tendency of the pigment rubrolone to fade upon exposure to direct sunlight wherein the pigment is combined with quercetin-5'-sulfonate. Pigment compositions comprised of rubrolone and quercetin-5'-sulfonate as well as food compositions containing these components are also disclosed.
Claims13
A pigment composition comprising rubrolone and quercetin-5'-sulfonate.
A pigment composition consisting essentially of quercetin-5'-sulfonate and rubrolone in a molar ratio of about 1:1 to about 10:1.
A food composition comprising a food base, rubrolone and an amount of quercetin-5'-sulfonate effective to reduce the tendency of the color imparted by said rubrolone to fade upon exposure to direct sunlight.
A process for producing a photostable colorant composition comprising combining rubrolone with an effective amount of quercetin-5'-sulfonate.
In a process for preparing food compositions containing the pigment rubrolone, the improvement comprising adding to said food composition an amount of quercetin-5'-sulfonate effective to reduce the tendency of the color imparted to the food composition by said rubrolone to fade upon exposure to direct sunlight.
