E150dColorantModerate concern
Caramel IV (Sulfite Ammonia)
In plain words
The short version
A dark brown caramel color produced with sulfite and ammonia, used in colas and sauces.
Why we flag it amber
The caramel colour in colas and sauces. Made with ammonia and sulphites, it can contain 4-MEI, a compound flagged as a possible carcinogen in animal studies. Levels are low and debated, but that's why we flag it.
Safety profile
ADI of 200 mg/kg body weight. The manufacturing process can yield trace 4-methylimidazole (4-MEI), classified as 'possibly carcinogenic' (IARC 2B). California Proposition 65 requires a warning label above certain 4-MEI levels, prompting major beverage manufacturers to reformulate.
