Purple Sweet Potato

Purple sweet potato is a variety of sweet potato with a deep purple flesh. It is a root vegetable native to Asia and is grown in many parts of the world, including the United States. The vibrant color comes from anthocyanins, the same antioxidants found in blueberries and red cabbage.

Purple sweet potato is used as a natural food coloring, providing a rich purple hue to a variety of products. It can also add a subtle sweetness and flavor. You'll often find it in snacks like chips and fruit snacks, baked goods, and beverages.

Purple sweet potato is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of anthocyanins, which are antioxidants linked to various health benefits in scientific literature, though more research is needed to confirm these effects in humans. JECFA and EFSA have evaluated anthocyanins and consider them safe for consumption. Evidence regarding specific health impacts at typical dietary intake levels is still developing.
