What class of natural pigments gives the Stokes Purple sweet potato its intense purple color?
Anthocyanins
The intense purple coloration characteristic of the Stokes Purple sweet potato variety is directly attributed to a high concentration of anthocyanins. Anthocyanins belong to the broader category of flavonoids and are responsible for the red, blue, or purple hues observed in many fruits and vegetables, such as blueberries and blackberries. This specific pigment concentration is the feature that chemically differentiates the Stokes Purple from its common orange counterparts, which derive their color primarily from beta-carotene. Therefore, anthocyanins are the specific compounds responsible for establishing the unique visual identity and contributing the primary health benefits associated with this variety.
