Typical of anthocyanins, the hue of Purple Corn color is dependent on pH and concentration. At low pH levels, it exhibits a vibrant orange-red color, allowing near hue matches to Red #40. This red hue match can be achieved in vitamin enhanced waters or sports drinks, as well as in hard candies and gummies/jellies. In some cases, the addition of citric acid may be needed to achieve the desired hue. Closer hue matches can be achieved by blending purple corn with other natural colors.
