Carotenoids are naturally occurring pigments found in many fruits, vegetables, algae, and plants. They are responsible for the bright yellow, orange, and red colors seen in foods such as carrots, tomatoes, pumpkins, and sweet potatoes. Common carotenoids include beta-carotene, lutein, lycopene, and astaxanthin.
These compounds are widely used in food, beverage, dietary supplement, animal feed, and personal care applications. In food products, carotenoids are often used as natural colorants to enhance appearance, while in supplements they are valued for their nutritional properties. Their plant-based origin has contributed to growing interest in natural ingredients across multiple industries.
Carotenoids can be sourced naturally from plants and algae or produced through commercial manufacturing processes.
