Abstract

A method of coloring foods using a color system comprising a diluent and a colorant in particle form is disclosed. The color of a food can be controlled by controlling the particle size and dilution ratio of the colorants. The colorants become visible on the food when the product to which the colorants are applied is exposed to heat.
