What specific compounds give the purple daikon its visually stunning color?
Answer
Anthocyanins
The striking visual characteristic of the purple daikon—its deep violet exterior—is attributed to the presence of anthocyanins. Anthocyanins are a class of potent, naturally occurring flavonoid pigments found in many deeply colored fruits and vegetables, such as blueberries and red cabbage. In the case of the purple daikon, these compounds are responsible for absorbing light in the green-yellow spectrum, thus reflecting the violet hue we perceive. Beyond their aesthetic contribution, anthocyanins are recognized as powerful antioxidants that are particularly linked to supporting improved heart health, adding a chemical layer of benefit atop the radish's existing nutritional profile.
