Sodium benzoate is a salt derived from benzoic acid, a naturally occurring compound found in various fruits and spices. Its chemical formula is C7H5NaO2. As a food preservative, sodium benzoate is widely used in the food and beverage industry to inhibit the growth of bacteria, yeast, and fungi, thus extending the shelf life of products.

The primary function of sodium benzoate is to prevent spoilage and maintain the freshness of a wide range of items, including soft drinks, juices, jams, and condiments. It works by converting into benzoic acid in acidic conditions, creating an environment unfavorable for microorganisms.

Beyond its role in food preservation, sodium benzoate is also employed in cosmetics, pharmaceuticals, and various industrial applications due to its antimicrobial properties. It is available in both granular and powder forms, making it versatile for different manufacturing processes.

While generally recognized as safe when used within recommended limits, it’s essential to adhere to regulatory guidelines to ensure its safe application. Sodium benzoate continues to be a crucial ingredient in the preservation and stability of numerous consumer products across various industries.
