Potassium bromate Uses

Potassium bromate (CAS NO.7758-01-2) can be used as oxidant, canned food additives and wool processing agent.It is typically used as a flour improver, strengthening the dough and allowing higher rising. It might also be used in the production of malt barley where it may be used safely, which includes labeling standards for the finished malt barley product.
