It is used in broiler chicken feed to enhance the yellow colour of chicken skin Canthaxanthin (pronounced /?kæn???zæn??n/ ( listen)) is a carotenoid pigment widely distributed in nature. Carotenoids belong to a larger class of phytochemicals known as terpenoids. The chemical formula of canthaxanthin is C40H52O2. It has E number E161g.; Canthaxanthin is a food additive used for farmed salmon raised in environments where astaxanthin sources are not available. Canthaxanthin gives salmon a pink color similar to pink/red species of wild salmon, while at the same time acting as an antibiotic. It has E number E161g. -- Wikipedia; Canthaxanthin is not found in wild Atlantic Salmon, but is a minor carotenoid in Pacific Salmon. Canthaxanthin is used in farm-raised trout. Canthaxanthin is used in combination with astaxanthin for some salmon feeds.; The analysis of canthaxanthin content in salmon is a scientifically-accepted method to determine the origin of salmons. -- Wikipedia; Xanthophyll; A trans-carotenoid pigment widely distributed in nature. The compound is used as an oral suntanning agent and as a food and drug coloring agent. Oral ingestion of the compound causes canthaxanthin retinopathy. -- Pubchem 4,4'-Diketo-b-carotene 4,4'-Diketo-beta-carotene 4,4'-dioxo-b-Carotene 4,4'-Dioxo-beta-carotene 4,4'-dioxo-β-carotene all-trans-b-Carotene-4,4'-dione all-trans-beta-Carotene-4,4'-dione all-trans-β-carotene-4,4'-dione all-trans,beta-Carotene-4,4'-dione Aphanicin b,b-Carotene-4,4'-dione beta-Carotene-4,4'-dione beta-Carotene-4,4'-dione, all-trans- beta,beta-Carotene-4,4'-dione beta,beta-Carotene-4,4'-dione (9CI) C.I.

These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone.
