Potassium Bromate

Commonly Used in:
Flour in bread

Banned in Europe, Canada, Asia, and Brazil, potassium bromate is an additive that chemically ages flour, strengthening its elasticity. In the US, the FDA approves its use up to 75 parts per million in flour, and manufacturers must list the ingredient on food labels. Only the state of California requires foods containing this additive to carry a warning label. Potassium Bromate has caused cancer in some animals, and even small amounts create a risk for humans.

Manufactuers defend the additive claiming that the baking process converts potassium bromate into a salt, potassium bromide. However, if ingredients aren’t mixed at the correct ratios, or aren’t cooked properly, the original compound may remain.

You may see the additive also listed as bromate flour, it is important to read all food labels carefully and monitor your food intake.
