What is Potassium Bromate?
Potassium bromate is a white solid. It is known as a strong oxidizing agent. This means it can cause other substances to lose electrons, which often leads to chemical reactions.
How is it Made?
Scientists can make potassium bromate in a lab. One way is by mixing bromine with hot potassium hydroxide. Another method involves using electrolysis on a solution of potassium bromide. Electrolysis uses electricity to cause a chemical change.
What is it Used For?
Potassium bromate has been used to improve wheat flour. When added to flour, it helps make bread dough stronger and gives baked bread a better texture.
Why is it Banned in Some Places?
Even though it can improve flour, many countries have banned potassium bromate from being used in food. This is because it might be a carcinogen. A carcinogen is a substance that could potentially cause cancer.
When bread is baked, the heat usually breaks down potassium bromate into harmless substances. However, if too much is used, or if the bread is not baked long enough, some of the potassium bromate might remain in the final product. This leftover amount could be harmful if eaten. Because of this risk, many places prefer to avoid using it in food altogether to keep people safe.
