Which specific carotenoid is primarily responsible for bestowing the distinctive, vibrant red color upon ripened bell peppers?
Answer
Capsanthin
The intense coloration observed in fully ripened red bell peppers is a direct visual marker for a high concentration of specific phytochemicals known as carotenoids. While beta-carotene is present and converts to Vitamin A, the compound specifically credited with giving the pepper its signature deep red hue is capsanthin. Alongside capsanthin, another related carotenoid called capsorubin is also present in high amounts. These compounds function as potent fat-soluble antioxidants, working in concert with Vitamin C to neutralize free radicals and protect various bodily systems from oxidative stress.
