Sodium benzoate is a common food preservative used in food and beverage production. It is primarily used to inhibit the growth of bacteria, fungi, and yeast, thereby extending the shelf life of products. Sodium benzoate is effective against a wide range of microorganisms and is particularly useful in acidic foods and beverages with a pH below 4.5. It is commonly found in carbonated drinks, fruit juices, jams, jellies, salad dressings, pickles, sauces, and condiments.
