Purple Sweet Potato Extract

Purple sweet potato extract is a natural colorant derived from the purple flesh of the sweet potato (Ipomoea batatas). The vibrant color comes from anthocyanins, a type of antioxidant also found in blueberries and red cabbage. The extract is typically produced by washing, chopping, and pressing the sweet potatoes, followed by extraction and purification of the anthocyanins.

Manufacturers use purple sweet potato extract to provide a natural purple or reddish-blue color in a variety of food products. It is often found in candies, beverages, dairy products, and baked goods where a natural colorant is desired.

Purple sweet potato extract is generally recognized as safe (GRAS) by the FDA for use as a food colorant. Anthocyanins, the compounds responsible for its color, are antioxidants that have been studied for potential health benefits, though research is ongoing. Regulatory bodies like EFSA have evaluated anthocyanins and found them to be safe. Evidence on specific health outcomes at typical dietary intake levels is still developing.
