Carotenoids are organic pigments that provide the red, yellow and orange colors found primarily in algae, plants and photosynthetic bacteria. They also can be found in some non-photossynthetic yeasts, molds and bacteria.

Carotenoids are responsible for the bright colors of red peppers, sweet potatoes, tomatoes and carrots, among other foods. They are a natural fat-soluble antioxidant and are most known for their ability to be a great source of vitamin A.

Beta-carotene, cryptoxanthin and alpha-carotene are some of the most popular carotenoids. They are mainly found in foods such as carrots, peaches, nactarines, oranges, sweet potatoes, red and yellow peppers and pumpkins.
