The vibrant yellow color of a ripe papaya is primarily attributed to the presence of carotenoid (caricaxanthin) pigments. As the fruit ripens, the green chlorophyll, which is dominant in unripe fruits, breaks down. Simultaneously, specialized cell organelles called chromoplasts synthesize and accumulate these yellow and orange carotenoids, such as caricaxanthin and beta-carotene. These pigments are responsible for a wide range of yellow, orange, and red hues found in many fruits and vegetables.
