Consumer Advice ​

Potassium bromate was long used as a flour treatment agent and bread improver to strengthen dough and increase loaf volume. However, animal studies suggest it may be carcinogenic, and it has been banned in food in China, the EU, the UK, Canada and many other countries. Only a few jurisdictions still permit it under strict controls. Consumers may prefer bread and bakery products made with bromate-free flour.
