Sodium Benzoate

Definition

Sodium benzoate is a widely used food preservative that helps prevent the growth of bacteria and fungi in food products.

Scientific / Technical Definition

Sodium benzoate, the sodium salt of benzoic acid, is a chemical compound with the formula C7H5NaO2. It is commonly used as a preservative in foods due to its ability to inhibit the growth of potentially harmful bacteria, yeast, and molds. Functioning efficiently in acidic environments, sodium benzoate is often found in foods and beverages with a naturally low pH.

Benefits

• Preserves food by preventing microbial growth.
• Extends the shelf life of various products.

Examples

• Soft drinks
• Fruit juices
• Condiments
• Salad dressings

Additional Information

• Known issues: Consuming high amounts of sodium benzoate in combination with ascorbic acid (vitamin C) may lead to the formation of benzene, a substance linked to cancer in high concentrations. Therefore, it's regulated and monitored in food processing to ensure safety.
