Abstract
Curcumin is employed for the purpose of detecting and warning of the presence of cyanide in a food, drug, or other oral composition. The curcumin is incorporated into a food packaging material. In the presence of cyanide, the curcumin undergoes a color change causing at least a portion of the packaging material to manifest a color change. The color change is sufficient to be detected by an observer, thereby providing a warning of cyanide adulteration of the product.
