Abstract
An improved pigment composition containing an anthocyanin pigment and a pigment-improving agent selected from the group consisting of flavonoid glycuronides, flavonoid glucuronides, and caffeic acid derivatives. The pigment-improving agents deepen and improve the intensity of the anthocyanin pigment and increase its stability in the presence of light, heat and/or pH.
