• 世界保健機関（WHO）

  Canthaxanthin, a naturally-occurring carotenoid with a deep redorange colour, is widely used as a food colouring agent. Since the mid-1970s it has been included in oral 'artificial suntan' preparations. It is also available in preparations used in the treatment of certain photodermatoses. By the mid-1980s its use in such preparations had been associated with the accumulation of crystalline deposits in the retina. Reported functional changes relating to dark adaptation have been of marginal clinical significance and largely reversible. Nevertheless, this has led to the withdrawal of artificial suntan preparations containing canthaxanthin by several regulatory authorities. Preparations for treatment of photodermatoses remain available in some but not all of these countries.

• 一般的な説明

  Canthaxanthin (red diketocarotenoid or 4, 4′-diketo-β-carotene), is a common xanthophyll found naturally in microorganisms and marine organisms, as well as in certain animals. It acts as an antioxidant in living organisms. The potential antioxidant activity of canthaxanthin is due to the presence of conjugated double bonds in its structure. It finds applications in various fields including poultry, fishery, cosmetics, medicine, and pharmaceuticals. In food industries, canthaxanthin can be used as a coloring agent.
