Is Caramel Color Safe?

Quick Answer: Not all caramel colors are equal. Class IV caramel color (made with ammonium compounds) contains 4-MEI, which California lists as a carcinogen. It's found in Coca-Cola, Pepsi, dark beers, and soy sauce. Classes I-III caramel colors are considered safer.

Caramel color is the world's most widely used food coloring by volume. There are four classes: Class I (plain caramel, safest), Class II (caustic sulfite process), Class III (ammonia process), and Class IV (sulfite ammonia process). Classes III and IV produce 4-methylimidazole (4-MEI) as a byproduct — a compound that caused lung cancer in mice and is listed under California's Proposition 65. In 2014, Consumer Reports found that some sodas contained 4-MEI levels exceeding California's safe harbor threshold. Coca-Cola and Pepsi reformulated their caramel color to reduce 4-MEI levels. However, the FDA maintains that 4-MEI at current levels does not pose a health risk. The EU assigns different E-numbers to each class (E150a-d) and has set limits on 4-MEI content.
