Beta-carotene is a naturally occurring pigment found in plants, particularly in carrots and other orange and yellow fruits and vegetables. It is a type of carotenoid, which is a class of organic pigments that are responsible for the vibrant colors of many plants. Beta-carotene is a precursor to vitamin A, which is essential for maintaining healthy vision, immune function, and skin health. Because beta-carotene is a potent antioxidant and is converted to vitamin A in the body, it is often added to foods as a nutrient supplement or as a color additive. It is commonly used in processed foods, such as margarine, baked goods, and snacks, to improve their nutritional profile and enhance their appearance.
