Delta-carotene, also known as δ-carotene, is a naturally occurring carotenoid hydrocarbon pigment found in various plants, including tomatoes and carrots. It contributes to the yellow-orange coloration of these foods. Structurally, it is similar to beta-carotene but features an epsilon ring instead of a beta ring, resulting in different spectral properties. As a lipophilic compound, it is absorbed in the presence of dietary fats and may exhibit antioxidant properties, helping to neutralize free radicals in biological systems. Research indicates potential health benefits similar to other carotenoids, including support for eye health and immune function, though it is less studied than alpha or beta-carotene.
