What this is
Potassium bromate is an oxidizing additive sometimes used to “condition” flour for commercial bread products, including some buns and rolls used in fast food. It can improve dough strength and oven rise. Baking is intended to convert bromate to bromide, but small residual amounts can remain if baking conditions aren’t well controlled. Because it caused tumors in animals and is classified as a possible human carcinogen, some places prohibit it, and California will ban it in foods starting in 2027. In the U.S., it can still be used within specified limits, so ingredient labels are the best way to spot it.
