E924A – Potassium Bromate

Potassium bromate, designated as E924A, is a chemical compound commonly used in the food industry as a flour improver. It enhances dough strength, facilitates better rising, and contributes to the desired texture in bread and other baked goods. 

Danger Level: 5 – Very Dangerous

Purpose in Products

  • Flour Improver: Potassium bromate is added to flour to strengthen dough, improve its elasticity, and promote a higher rise in baked products. This results in bread with a finer crumb and improved volume. 

Health Considerations

Potassium bromate has been associated with several health concerns:

  • Carcinogenic Potential: Studies have shown that potassium bromate is a possible human carcinogen, with laboratory animal studies indicating an increased incidence of tumors, particularly in the thyroid and kidney. 
  • Thyroid Disruption: The compound can interfere with thyroid hormone production, potentially leading to imbalances that affect metabolism and overall endocrine health. 

Impact on Children

There is no specific evidence to suggest that potassium bromate has any adverse effects on children. However, due to its potential health risks, it is advisable to limit exposure to this additive.

Impact on Taste

Potassium bromate is tasteless and odorless, ensuring it does not alter the natural flavor of the products it is used in.

Compatibility with Other Additives

Potassium bromate is compatible with various other food additives, including other flour treatment agents and preservatives. Its synergistic effects can enhance the overall quality and sensory attributes of baked goods.

Natural Occurrence

Potassium bromate is a synthetic compound and does not occur naturally.

Alternatives and Substitutes

For those seeking alternatives to potassium bromate, options include:

  • Ascorbic Acid (Vitamin C): Commonly used as a dough conditioner and antioxidant in bread-making.
  • Enzymes: Certain enzymes can be used to improve dough properties and bread quality.

Regulation

Potassium bromate is banned in several countries, including the European Union, due to health concerns. In the United States, its use is permitted but highly restricted, with many manufacturers opting for alternative dough conditioners. 

Conclusion

Potassium bromate (E924A) is an effective flour improver that enhances the quality of baked goods. However, due to its potential health risks, including carcinogenicity and thyroid disruption, its use is banned in several countries. Consumers are advised to be aware of its presence in food products and consider alternatives when possible.
