E928 – Benzoyl Peroxide

Benzoyl peroxide, designated as E928, is a chemical compound commonly used in the food industry as a flour treatment agent and bleaching agent. It oxidizes naturally occurring pigments in flour, resulting in a whiter appearance preferred by some consumers. 

Danger Level: 1 – Mostly Safe

Purpose in Products

• Flour Treatment Agent: Benzoyl peroxide is added to flour to bleach and improve its color, yielding a consistent and appealing appearance in baked goods. 

Health Considerations

Benzoyl peroxide is generally recognized as safe when used within established limits. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated its use and determined that treatment of flour with benzoyl peroxide at specified concentrations does not pose a safety concern. 

Impact on Children

There is no specific evidence to suggest that benzoyl peroxide has adverse effects on children when used appropriately in food products. However, as with all additives, moderation is advised.

Impact on Taste

Benzoyl peroxide is tasteless and does not alter the flavor profile of flour or baked goods. Its primary function is to improve the visual appearance of flour by bleaching.

Compatibility with Other Additives

Benzoyl peroxide is compatible with various other food additives used in flour and baking processes, such as dough conditioners and preservatives, contributing to the overall quality and sensory attributes of the product.

Natural Occurrence

Benzoyl peroxide is a synthetic compound and does not occur naturally. It is produced through chemical reactions involving benzoyl chloride and sodium peroxide. 

Alternatives and Substitutes

While benzoyl peroxide is effective in its role, alternatives such as ascorbic acid (vitamin C) and enzymes can also be used to achieve similar flour treatment effects without bleaching.

Regulation

The use of benzoyl peroxide as a flour treatment agent varies by country. In the European Union, its use in food processing is subject to strict regulations due to health concerns. In the United States, benzoyl peroxide is permitted for flour treatment but is regulated to ensure safety. Consumers are advised to check local regulations and product labels for information on flour treatment agents.

Conclusion

Benzoyl peroxide (E928) is a widely used flour treatment and bleaching agent that enhances the visual appeal of flour and baked goods. When used within regulated limits, it is considered safe for consumption. As with all food additives, consumers are encouraged to enjoy products containing benzoyl peroxide in moderation.
