How Lycopene Serves as a Natural Red Pigment and Potent Antioxidant

Lycopene is a naturally occurring carotenoid pigment responsible for the bright red color in tomatoes, watermelon, pink grapefruit, and other red fruits. Beyond its coloring properties, lycopene is widely recognized for its strong antioxidant activity and potential health benefits, making it a valuable ingredient in food, nutraceutical, and cosmetic applications.

Composition of Lycopene

Lycopene is a fat-soluble carotenoid composed of a long chain of conjugated double bonds, which provides its red color and free radical scavenging ability. Unlike β-carotene, lycopene does not have pro-vitamin A activity but exhibits significant antioxidant potential.
