E924 – Potassium bromate

Description

Oxidizing agent used as a flour improver

Risks

Notes

Potassium bromate is a white, crystalline powder produced by treating potassium bromide with an oxidizing agent like chlorine or ozone. This industrial process creates a powerful oxidizing compound that's highly soluble in water. The manufacturing involves carefully controlled chemical reactions to ensure the resulting powder meets food-grade specifications. As a flour improver, potassium bromate strengthens gluten in wheat flour, leading to higher-rising bread with better texture and volume. It works by creating chemical bonds between gluten proteins, making the dough more elastic and able to trap gas bubbles more effectively during baking. This results in fluffier, more consistent baked goods, particularly in commercial bread production and other yeast-based products. This is a synthetic chemical compound, not found naturally in foods. While suitable for vegetarian and vegan diets from an ingredient standpoint, potassium bromate has been banned in many countries including the European Union, Canada, and others due to potential health concerns. It's classified as a possible carcinogen, though it's designed to break down completely during proper baking. Some countries still permit its use with strict regulations, but many bakers and manufacturers have moved to alternative flour improvers.
