What specific pigments are responsible for the deep blue-purple color in potatoes?
Answer
Anthocyanins (ACNs)
The striking, deep blue-purple coloration observed in these specific potato varieties is the direct signature of a class of powerful polyphenol antioxidants called anthocyanins (ACNs). These same beneficial pigments are also responsible for the deep coloration seen in other well-known healthful foods, such as blackberries and wild blueberries. The presence of these anthocyanins is what sets the blue and purple potatoes apart from their white or yellow counterparts, contributing significantly to their enhanced health profile.
