What Is Potassium Bromate?

Potassium bromate (KBrO3) is rare but legal in the US. While its use has been banned in several other countries over recent years, it has not been banned in America. Potassium bromate is typically used as a flour improver. It is an oxidizing agent and used in baking bread. Potassium bromate is also used in producing malt barley, where the FDA has prescribed certain conditions to be strictly adhered to. Potassium bromate is considered a category 2B carcinogen by the International Agency for Research in Cancer.
