描述
Dye used in food and feed additives. Prohibited in U.S.A. and Norway [DFC]
Erythrosine, also known as Red No. 3, is a cherry-pink synthetic fluorone food coloring. It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Erythrosine is commonly used in sweets such as some candies and popsicles, and even more widely used in cake-decorating gels. While commonly used in many countries of the world, erythrosine is less commonly used in the United States because Allura Red AC (Red #40) is generally used instead. However, Allura Red AC is banned in many European countries solely because it is an azo dye, despite scientific consensus of Red 40 having fewer known health risks. [Wikipedia].
