| Description | Erythrosine is a dye used in food and feed additives. Prohibited in U.S.A. and Norway Erythrosine is a cherry-pink synthetic fluorone food coloring. It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Its maximum absorbance is at 530 nm in an aqueous solution, and it is subject to photodegradation.[citation needed]; It is used as a food coloring, in printing inks, as a biological stain, a dental plaque disclosing agent and a radiopaque medium. It is commonly used in sweets and foods marketed to children such as cake icing and cake-decorating gels. It is also used to color pistachio shells. While commonly used in most countries of the world, erythrosine is rarely used in the United States due to its known hazards, with Allura Red AC (Red #40) being generally used instead. However, Allura Red AC is banned in many European countries because it is an azo dye, despite the fact that it has fewer known health risks than Erythrosine |
