Potassium bromate is typically used in the United States as a flour improver (E number E924). It acts to strengthen the dough and to allow higher rising. It is an oxidizing agent, and under the right conditions will be completely reacted to a form with a lower oxidation state in baking the bread.

Potassium bromate, or simply called bromate, is an oxidiser used to strengthen dough and enhance its elasticity. This helps bake uniform and whitened bread. Typically 15-30 parts per million (ppm) of potassium bromate is added to dough.

Potassium Bromate may be a CARCINOGEN in humans since it has been shown to cause kidney, thyroid, and gastrointestinal cancer in animals. * Many scientists believe there is no safe level of exposure to a carcinogen. Such substances may also have the potential for causing reproductive damage in humans.
