Yellow 5 Also known as Tartrazine or E102, the Yellow 5 dye is a type of â€œazoâ€� dye with few chemical similarities to all other food colorings. It is the second-most-widely used coloring substance and is used in the coloring of potato chips, jams, candy, drinks, pet food, etc. It can produce various shades of green according to the manufactureâ€™s wishes as well as many yellow colors. All dyes are considered additives by the FDA through the Federal Food, Drug, and Cosmetic Act (FD&C Act) since it is not used for the purpose of consumption, but to improve the appearance of the product. Yellow 5 is also used in hair dyes and shampoos. Many allergic reactions have been reported due to prolonged use of the dye such as worsened asthma symptoms, skin rashes, and uticaria. Those intolerant of aspirin are highly recommended to avoid this additive. The dye has been banned in Norway, Austria, and Germany, but not all of Europe since it would affect many food businesses economically. Yellow 5 may be contaminated with carcinogens such as benzidine and 4-aminobiphenyl during the manufacturing process. There is no scientific proof of Yellow 5â€™s links to cancer, but it is â€œGenerally Recognized As Safeâ€�, or GRAS. "Electronic Code of Federal Regulations." GPO Home Page. Title 21.
