Sodium Benzoate

Definition

Sodium benzoate is a type of preservative commonly used in processed foods and beverages to extend shelf life by inhibiting the growth of bacteria, yeast, and fungi.

Scientific / Technical Definition

Sodium benzoate is the sodium salt of benzoic acid with the chemical formula C7H5NaO2. It acts by lowering the pH level, which inhibits the enzyme activity necessary for microbial growth, effectively preserving the product it's added to.

Benefits

• Helps to prevent food spoilage by inhibiting microbial growth.
• Extends the shelf life of processed foods and beverages.

Examples

• Carbonated drinks
• Salad dressings
• Sauces
• Processed meats

Additional Information

• knownIssues: High consumption may be associated with allergies or hyperactivity in sensitive individuals. It's often combined with ascorbic acid (Vitamin C), which can potentially form benzene, a known carcinogen, particularly in beverages exposed to heat and light.
