After oxidizing to convert the dye to its water-insoluble, colored, form, the aqueous solu- tion is dried to provide a dry, water-soluble food colorant comprising the substrate dyed with the water-insoluble dye. The product is conveniently provided in particulate form such as by spray dry- ing, and finds particular use in dry beverage mixes where a water-soluble colorant is desired.
