Xanthophyll is widely used in the food industry as a natural colorant, providing yellow to red hues in products like egg yolks, poultry feed, and processed foods. It is also a key ingredient in dietary supplements aimed at promoting eye health, particularly in reducing the risk of age-related macular degeneration due to its antioxidant properties. In the cosmetics industry, xanthophyll is incorporated into skincare products for its potential to protect the skin from oxidative stress and UV damage. Additionally, it plays a role in aquaculture, where it is added to fish feed to enhance the pigmentation of salmon and trout, improving their market appeal.
