Metabolite Identification
Common NameCitranaxanthin
DescriptionCitranaxanthin is found in citrus. Citranaxanthin is a constituent of Sinton citrangequat (a Citrus-Poncirus-Fortunella hybrid) Citranaxanthin is a carotenoid pigment used as a food additive under the E number E161i as a food coloring. There are natural sources of citranaxanthin, but it is generally prepared synthetically. It is used as an animal feed additive to impart a yellow color to chicken fat and egg yolks.
