Brief Introduction:
Potassium bromate (KBrO₃) is a widely used oxidizing agent in various industries, including food, cosmetics, and pharmaceuticals. It is commonly employed as a bread improver in baking processes due to its ability to enhance dough elasticity and texture. However, its use has raised significant health concerns due to its potential to induce oxidative stress, genotoxicity, and cytotoxicity. Studies have shown that KBrO₃ can cause DNA damage, chromosome aberrations, and cell death through the production of reactive oxygen species (ROS) and depletion of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), and glutathione (GSH). It has also been classified as a possible human carcinogen (Group 2B) by the International Agency for Research on Cancer (IARC). Despite regulatory restrictions and bans in some countries, its presence in food products remains a public health concern, necessitating proper precautions and alternative non-toxic additives to mitigate its harmful effects.
Oxidizing Agents
Potassium bromate is a strong oxidizing agent. It is used in various industrial processes to promote oxidation reactions due to its ability to donate oxygen atoms.
Inorganic Compounds
It is an inorganic compound composed of potassium (K⁺), bromine (Br), and oxygen (O₂⁻). Inorganic compounds are those that do not contain carbon-hydrogen bonds.
Halogen Compounds
Potassium bromate contains bromine, which is a halogen element. Halogens are highly reactive non-metal elements found in Group 17 of the periodic table.
Food Additives
In the food industry, potassium bromate is used as a food additive, specifically as a flour improver or dough conditioner. It helps to strengthen the dough and improve the texture of bread.
