Sodium benzoate (chemical formula: C6H5CO2Na), E number E211, is the sodium salt of benzoic acid. It is an acid preservative with a better effect in acidic environments. Widely used as a food preservative to prevent deterioration, prolong shelf life, and inhibit acidity. However, concerns over toxicity have led to restrictions on its use in some countries like Japan.

Sodium benzoate is mostly white particles, odorless or slightly with a benzoin odor, slightly sweet, and easy to dissolve in water. It acts as an acidic preservative with no bactericidal effect in alkaline mediums. Its optimal pH for preservation is 2.5-4.0. Sodium benzoate is lipophilic, penetrating cell membranes to inhibit amino acid absorption and enzyme activity, serving as an effective food preservative.
