Azodicarbonamide is used to treat and bleach flour, and as a dough conditioner in breads.
Azodicarbonamide decomposes to produce, among others, semicarbazide. Semicarbazide has shown carcinogenic and DNA-damaging effects in animal studies. Azodicarbonamide has been associated with allergy development; it is also currently being studied for use as an immunosuppressant drug.
Azodicarbonamide is banned as a food additive in Europe and Australia.
