E924B – Calcium bromate

Flour treatment agent

Description

White crystalline powder

Risks

Potential genotoxicity and carcinogenicity (kidney and thyroid tumors)

Notes

## E924B - Potassium Bromate **Potassium bromate** is a white, crystalline powder that's chemically produced by combining **potassium bromide** with an **oxidizing agent** like chlorine or ozone. This **synthetic compound** is manufactured in chemical facilities under controlled conditions to create a powerful oxidizing agent. The production process involves careful handling due to its reactive nature. In food production, potassium bromate functions as a **flour improver** and **dough conditioner**, primarily in commercial bread making. It strengthens gluten networks in dough, helping create bread with better volume, texture, and structure. When used properly, it breaks down during the baking process into harmless **potassium bromide** and oxygen, leaving no residue in the final product. **Important safety note**: E924B is **banned in many countries** including the European Union, UK, Canada, and others due to health concerns, as it's classified as a possible carcinogen. While still permitted in some regions like parts of the United States (with strict usage guidelines), many commercial bakers have moved to safer alternatives. It's suitable for **vegetarian** and **vegan** diets from a ingredient standpoint, but its restricted status means consumers in many countries won't encounter it in their food supply.
