Caramel Coloring

Caramel coloring is a dark brown food coloring made by heating sugars, such as corn syrup, sucrose, or invert sugar. Depending on the process and reactants used, it can range from a light yellow-brown to a dark brown. The four classes of caramel color (Class I, II, III, IV) are distinguished by the reactants used during heating, such as acids, alkalis, sulfites, or ammonia compounds.

Caramel coloring is used to give foods a brown color, ranging from light tan to dark brown. It is commonly found in baked goods, soft drinks, sauces, gravies, and processed snacks. Manufacturers use it to create or enhance the visual appeal of products, often mimicking the color of cooked ingredients.

Caramel coloring is generally recognized as safe (GRAS) by the FDA for use in food. Some forms of caramel coloring, specifically Class III and IV, can produce byproducts like 4-methylimidazole (4-MEI) during manufacturing. While studies in rodents have shown potential health concerns at very high doses, the U.S. National Toxicology Program has not classified 4-MEI as a carcinogen. International bodies like JECFA and EFSA have evaluated caramel colorings and established acceptable daily intakes for certain types, though specific numerical limits are not provided here.
