Canthaxanthin is a carotenoid pigment with orange color. It exists naturally in a variety of foods and can also be synthesized artificially. It is often used as an animal feed additive to make the color of egg yolk and poultry meat more vivid. It is mainly used as orange colorant when adding food, but it is rarely used. Some studies have shown that high intake of keratin may lead to its accumulation in the retina, but the 2010 assessment of the European food safety agency showed that the use of keratin is generally safe.
Canthaxanthin, β,β- Carotene-4,4 '- Dione), also known as cantharidin, amygdalin, chicken oil fungus yellow, chicken oil fungus yellow, edible Orange 8. It is an orange red carotenoid pigment and an antioxidant.
Keratin is naturally found in many foods, such as mushrooms, crustaceans, fish and eggs. This pigment can also be manufactured by artificial methods. It is mainly used in animal feed.

Feed addition
Keratin (food additive international number: ins161g) is mainly used as animal feed additive to make the color of egg yolk and poultry meat more bright and the color of salmon more ruddy.
Food coloring
Canthaxanthin can also be used in jam, candy, syrup, sauce, beverages containing carbon dioxide and other foods as colorants. However, keratin is more often used in animal feed rather than as an edible colorant.
Suntan pill
Keratin is also related to the sun tanning pills popular abroad. Due to its antioxidant properties, some people believe that taking it can increase the skin's ability to resist ultraviolet rays. Because after ingestion, it can accumulate in the fat layer of the skin and make the skin produce a change similar to tan. Some tanning agents use this natural pigment, but it is not approved by FDA.
According to some studies, ingestion of a large amount of keratin can lead to pigment accumulation in the retina.
In 1995, the food and Agriculture Organization of the United Nations / World Health Organization Joint Expert Committee on food additives (hereinafter referred to as the Committee) assessed the safety of keratin and designated the maximum allowable daily intake (ADI) of keratin as 0.03 mg per kilogram of body weight. (ADI) refers to the daily dose of the substance (depending on body weight) that an individual can ingest throughout his life without posing a significant risk to health.
The Committee believes that the use of keratin as a feed colorant is the main way for humans to ingest this pigment indirectly. In its recent assessment in 2000, the Committee concluded that the long-term intake of foods using keratin as a feed additive would not exceed the current daily allowable intake of keratin.
EFSA (European Food Safety Agency) assessed the dose of canthaxanthin in 2010 and concluded that the amount of food (directly added food pigment and from salmon, etc.) can not exceed the current ADI, so the approved use of canthaxanthin is safe.
The carcinogenicity of canthaxanthin was not evaluated by the International Cancer Institute. However, based on the information obtained from animal studies, the committee considered that there was no evidence that keratin could cause cancer.
