Sodium benzoate is one of the most commonly used chemical preservatives in the food industry, employed to inhibit microbial growth and extend product shelf life. This white, crystalline compound is highly soluble in water and is widely used in beverages, jams, sauces, and canned foods. By suppressing the activity of bacteria and fungi, sodium benzoate helps maintain product quality and ensures the production of safe and stable food items.

In addition to its primary role as a preservative, sodium benzoate also functions as an acidity regulator, contributing to improved taste and stability of food products. It is recognized as a safe additive by global health authorities when used within permitted limits, making it a widely applied and essential ingredient in modern food manufacturing.
