What specific pigments are responsible for the deep reddish-purple hue of red cabbage?

Answer

Anthocyanins

The striking deep reddish-purple coloration observed in red cabbage is directly attributable to the presence of pigments classified as anthocyanins. These compounds belong to the broader group of flavonoids and function as powerful antioxidants. The concentration of these specific pigments is significantly higher in purple varieties compared to their green counterparts, leading to superior antioxidant capacity. Scientific analysis further reveals that the complexity of these pigments is high, with over 36 different types identified, often built around a core structure like cyanidin 3-diglucoside-5-glucoside. Furthermore, these anthocyanins undergo chemical modification, known as acylation, through the attachment of various acids, which can influence their ultimate biological activity within the body.
