摘要：
The present invention is to provide anthocyanin pigments with improved heat-resistance and production thereof, and a method for coloring foods with said anthocyanin pigments and foods colored with said anthocyanin pigments. Heat-resistance in anthocyanin pigments is enhanced by adjusting an aqueous anthocyanin solution to a pH range of 4.0 to 6.5 at a temperature of 40 to 100° C.
