Sodium benzoate is a widely used preservative. It is primarily used to preserve acidic foods like pickles, jams, jellies, salad dressings, soft drinks, etc. It protects food by preventing the growth of fungus, bacteria, and yeast. It works by entering the individual cell of food and maintaining its PH levels thereby increasing the overall acidity. Sodium benzoate also enhances the flavor of acidic foods. Store in a cold and dry place.
