Carotenoids is a general term for an important class of natural pigments, belonging to compounds, commonly found in animals, higher plants, fungi, algae and bacteria, is a yellow, orange-red or red pigment, mainly containing β-carotene and γ-carotene, hence the name. Carotenoids are insoluble in water and soluble in fat and fat solvents, also known as lipochromes.

Plant carotenoids are found in a variety of yellow plastids or colored plastids, such as yellow leaves in the fall, yellow flowers, yellow and red fruits, and yellow tubers. Animal carotenoids are primarily pigments of fat, egg yolk, feathers and fish scales, and the carapace of shrimp and crabs. Animal carotenoids are generally bound to proteins, such as astaxanthin, which is contained in shrimp egg yolk, and shrimp ovalbumin, which is a complex of astaxanthin and a phospholipid-rich lipoprotein.
