Possible risks and effects

  • Higher intake mainly in people who drink a lot of cola.

For experts

Class IV caramel; its production can form 4-methylimidazole (4-MEI), which IARC classifies as Group 2B (possibly carcinogenic to humans). EFSA re-evaluated it in 2011 and saw no safety concern provided EU specifications limiting 4-MEI are met.
