Potassium Bromate
INS 924a
INS 924a, potassium bromate, bromate of potash
What it is
An oxidising flour-treatment and dough-strengthening agent identified internationally as INS 924a.
Why BOTIA flags it
BOTIA flags an explicit potassium bromate declaration because its regulatory treatment differs across jurisdictions. FDA information still describes specified U.S. food uses, while JECFA concluded that its use as a flour-treatment agent is not acceptable. Those regulatory positions do not tell BOTIA how much residue is present in a particular food.
BOTIA CAN
- Detect potassium bromate and INS 924a when they are explicitly declared.
- Show that different authorities and jurisdictions can reach different regulatory positions without presenting a label hit as an exposure measurement.
BOTIA CANNOT
- Measure residual bromate after baking or processing.
- Assume that flour or bread contains potassium bromate when it is not declared.
