Abstract
The present invention stabilizes curcumin against color changes by maintaining the curcumin itself at low, stable pH values, while not upsetting the pH balance of a dry food mix which may be placed in contact therewith. Preferably, the pH of the curcumin is maintained at a value within the range of from about 3.5 to about 4.5, and comprises a spray-dried intimate mixture of curcumin, an organic acid, a buffer, a dispersant for the curcumin, and a film-forming encapsulant. A preferred use of the colorant is in dry mixes for instant puddings which are alkaline due to the salts employed to cause setting.
