Potassium bromate

Chemical Formula: KBrO3


Bromated flour,
Bromic acid, potassium salt


White crystals or powder.


Potassium bromate is used as a flour improver, where it strengthens the dough, allowing higher rising. It is an oxidizing agent, and under the right conditions, will be completely used up in the baking bread. However, if too much is used, or the bread is not cooked long enough or at a high enough temperature, then a residual amount will remain.

Potassium bromate has been banned in several countries as a carcinogen.

Potassium Bromate: InChI=1/BrHO3.K/c2-1(3)4;/h(H,2,3,4);/q;+1/p-1/fBrO3.K/q-1;m
