The bright yellow pigment found in bananas is called "dopamine," but the yellow color itself is primarily due to the presence of carotenoids, specifically a type of carotenoid known as "xanthophyll." These pigments contribute to the distinctive color of ripe bananas and many other fruits and vegetables. The ripening process of bananas converts chlorophyll into carotenoids, leading to the yellow appearance as they mature. These natural pigments not only provide visual appeal but also offer antioxidant properties beneficial for health.
