Everything you need to know about sodium benzoate

Sodium benzoate is a common preservative used in the food industry and consumer products. Although it is considered safe in moderate amounts, its use has raised some public health concerns. In this article, we will address the most important aspects of sodium benzoate, from its functions to its potential health effects.

What is sodium benzoate?

Sodium benzoate is the sodium salt of benzoic acid, a compound that occurs naturally in various fruits such as blueberries and plums. In the industry, it is used as a preservative due to its antimicrobial properties, which help prevent the growth of bacteria, yeasts, and molds in food and beverages.

Where is sodium benzoate found?

This preservative can be found in a wide variety of products. It is commonly found in:

Soft drinks
Fruit juices
Sauces
Canned goods
Dairy products

In addition to its use in food, sodium benzoate is also used in cleaning products and cosmetics.

Is sodium benzoate safe?

Health regulatory agencies, such as the FDA and EFSA, have classified sodium benzoate as safe for human consumption at permitted doses. However, it has been observed that it can cause adverse reactions in certain people, particularly those with sensitivity to sulfates or those who suffer from asthma.

It is important to mention that its use is permitted up to a specific limit. The EFSA establishes that the acceptable daily intake (ADI) for sodium benzoate is up to 5 mg per kilogram of body weight. This means that, in general, moderate consumption does not pose a significant risk to health.

Possible health effects

Although sodium benzoate is considered safe in regulated amounts, it has been the subject of studies related to health. Some aspects to consider include:

Allergic reactions

Some people may experience allergic reactions to sodium benzoate, which can manifest as hives, rashes, or respiratory problems. If you have a history of allergies to preservatives, it is advisable to avoid products containing this compound.

Behavioral effects

Some studies have suggested a possible link between sodium benzoate and behavioral disorders in children, such as ADHD (attention deficit hyperactivity disorder). However, the evidence is still inconclusive and more research is needed on this topic.

Formation of benzene

Sodium benzoate can form benzene, a highly toxic compound, when exposed to high concentrations of light in combination with ascorbic acid (vitamin C). However, the rates at which this occurs are quite low and generally remain within regulated limits.

Conclusion

Sodium benzoate is a widely used preservative and is considered safe for most people when consumed in recommended amounts. However, it is essential to be informed about its presence in food products and its potential impact on health.
