What specific class of flavonoid pigments gives the red onion its deep, vibrant purple hue and acts as a potent antioxidant?
Answer
Anthocyanins
The deep, vibrant purple color characteristic of the red onion is directly attributed to the presence of anthocyanins. Anthocyanins are a specific class of flavonoid pigments which are recognized for their potent antioxidant capabilities. These compounds are responsible for the dark coloring seen not only in red onions but also in berries, highlighting their role in providing deep pigmentation in plant matter. Because they function as antioxidants, they help neutralize unstable molecules within the body, thereby contributing significantly to the overall health profile associated with consuming red onions.
