Description | FD & C Yellow No. 5 is principally the trisodium salt of 4,5-dihydro-5-oxo-l-(4-sulfophenyl)-4-[4-sulfophenyl-azo]-lH- pyrazole-3-carboxylic acid. The colorant is a yellow-orange powder that dissolves in water to give a solution golden yellow at neutrality and in acid. When dissolved in concentrated sulfuric acid, it yields an orange-yellow solution that turns yellow when diluted with water. FD & C Yellow No. 5 is regularly used in desserts (e.g., dessert powders, puddings, custards, gelatin, ice cream), candy, preserves, beverages (including carbonated soda beverages and flavored drink powders), prepared meats, and canned and frozen vegetables.
