Description | Green #3 is principally the inner salt disodium salt of N-ethyl-N-[4-[[4-[ethyl[(3-sulfophenyl)methyl] amino]phe- nyl](4-hydroxy-2-sulfophenyl)methylene]-2,5-cyclohexadien- 1 -ylidene]-3-sulfobenzenemethanaminium hydroxide. The colorant is a red to brown-violet powder or collection of crystals that dissolves in water to give a solution blue-green at neutrality, green in acid, and blue-violet in base. When dissolved in concentrated sulfuric acid, it yields a brown-orange solution that turns green when diluted with water. When heated to 130° with glycerine triacetate and an excess of acetic anhydride, acety- lation of its phenolic hydroxyl group causes a color change from green to light blue. Green #3 is regularly used in beverages, desserts (puddings, ice cream, sherbet), candy, bakery goods, dairy products, and maraschino cherries. The color is also used in pharmaceuticals, cosmetics and histological stains. |
