Abstract
Heat-triggered colorants for altering the color of a food, methods for changing the color of a food using heat-triggered colorants, and methods for making heat-triggered colorants for food. The heat-triggered colorants may comprise a mixture comprising a carrier having a melting point and a GRAS (Generally Recognized as Safe) first food colorant having a color, and a coating encapsulating the mixture and masking the color of the first food colorant. When the heat-triggered colorant is exposed to a temperature greater than the melting point of the carrier, the carrier melts and releases the first food colorant, thereby unmasking the color of the first food colorant.
