Sodium Benzoate (E211) (CAS 532-32-1) is a high-performance food preservative presented as white granules or crystal powder. It features slight benzoin odor with sweet and astringent taste, and shows excellent stability in air. This additive is easily soluble in water and ethanol, and its core function is to inhibit the growth of bacteria, mold, and yeast in food systems. The antibacterial effectiveness of Sodium Benzoate is closely related to the pH value of food, with the optimal antisepsis pH range of 2.5~4.0. As a well-researched and widely used food additive, it plays a crucial role in extending the shelf life of various food products while ensuring food safety and freshness.
