1. What Is Potassium Bromate and Why Is It Used in Food?
Potassium bromate (KBrO3) is an oxidizing agent that has been used in the baking industry since the early 20th century. It’s primarily used as a dough conditioner, which means it improves the texture and rise of bread and other baked goods. According to research from the International Agency for Research on Cancer (IARC), potassium bromate is classified as a possible human carcinogen. The substance’s impact on genetic material and its potential to cause tumors in lab animals has raised significant concerns, leading to restrictions and bans in several countries, but its continued use in some regions underscores the need for awareness and informed choices.
1.1 How Does Potassium Bromate Improve Baked Goods?
Potassium bromate offers several key benefits to bakers:
- Strengthens Dough: It oxidizes the gluten in flour, making the dough stronger and more elastic. This allows it to hold more gas, resulting in a lighter, airier texture.
- Increases Volume: By improving dough strength, it allows baked goods to rise higher during baking.
- Whitens Flour: Potassium bromate can bleach the flour, giving baked goods a whiter, more appealing color.
1.2 Why Is Potassium Bromate Controversial?
The controversy surrounding potassium bromate stems from its potential health risks:
- Possible Carcinogen: The International Agency for Research on Cancer (IARC) has classified potassium bromate as a possible human carcinogen (Group 2B). This classification is based on sufficient evidence of carcinogenicity in experimental animals.
- Tumor Formation: Studies on lab animals have shown that exposure to potassium bromate can increase the incidence of tumors in the thyroid and peritoneum (the lining of the abdominal cavity).
- DNA Damage: Potassium bromate can break down into oxides and radicals in the body, which can damage DNA and may contribute to cancer development. Research has shown DNA damage in human liver and intestine cells exposed to potassium bromate.
