Sodium benzoate serves as a preservative in many acidic foods and beverages, including soft drinks, fruit juices, pickles, and sauces. By inhibiting the growth of certain microorganisms, it helps extend shelf life and maintain the quality of these products. The compound works best in products with a pH of 4.5 or lower, making it particularly effective in acidic environments. Consequently, its use in combination with other food preservation methods, such as refrigeration and low-temperature storage, enhances the overall safety and longevity of perishable items.
