Infobox disclaimer and references

Erythrosine (Tetraiodofluorescein) is a cherry-pink coal-based fluorone food dye. Its maximum absorbance is at 530 nm[1] in an aqueous solution, and it is subject to photodegradation[citation needed].

Classification

It is listed under the following number systems:

Uses

Template:Not verified It is used as a food dye, in printing inks, as a biological stain, a dental plaque disclosing agent and a radiopaque medium. Although Red #3 has been highly implicated as a carcinogen[2], it is commonly used in sweets and foods marketed to children such as candies, popsicles, cake frosting,[citation needed] and cake-decorating gel.[3] Diamond Foods uses Red #3 to dye pecan shells red in its Blue Diamond line of mixed nuts for cosmetic reasons.[4] It is also used in strawberry Slim-Fast and its generic counterpart.[citation needed] McCormick uses it as well in their "Salad Toppins." Because of the well-known hazards of Red #3[5], Red #40 is much more commonly used by most food manufacturers in USA.[citation needed] Though in most of Europe and the rest of the world Red #3 is preferred over Red #40.[citation needed]
