Carotenoids color

Canthaxanthin. The newest of the synthetically produced carotenoid color additives, canthaxanthin [514-78-3] (39) (P-carotene-4-4 -dione), became commercially available about 1969 (60). Its Cl designation is Food Orange 8, Cl No. 40850. Its EEC designation is E 160g. [Pg.449]

Canthaxanthin crystallines from various solvents as brownish violet, shiny leaves that melt with decomposition at 210°C. As is the case with carotenoids in general, the crystals are sensitive to light and oxygen and, when heated in solution or exposed to ultraviolet light or iodine, form a mixture of cis and trans stereoisomers. Consequentiy, crystalline canthaxanthin should be stored under inert gas at low temperatures. Unlike the carotenoid colorants P-carotene and P-apo-8 -carotenal, canthaxanthin has no vitamin A activity. It is chemically stable at pH 2—8 (the range normally encountered in foods) and unaffected by heat in systems with a minimal oxygen content. [Pg.449]
