What it is

Bromated wheat flour is wheat flour that has been treated with potassium bromate. Potassium bromate is an oxidizing agent added to flour to improve its baking qualities.

Why it's used

When added to flour, potassium bromate strengthens the dough, improves its elasticity, and helps create a better texture and higher volume in baked goods. It is commonly used in commercial baking for products like breads, buns, and pizza crusts.

Health notes

Potassium bromate is an FDA-approved additive for use in flour, with specific limits. JECFA has stated that potassium bromate is not appropriate for use as a flour treatment agent and did not set an acceptable daily intake. Animal studies have linked high doses of potassium bromate to kidney tumors and other health issues. The FDA maintains that potassium bromate is safe when used correctly because it is expected to convert to harmless potassium bromide during the baking process. However, if not fully baked, residues of potassium bromate may remain. California has banned potassium bromate in food products starting in 2027.
