Description
Sodium benzoate is a common type of food preservative and is the sodium salt of benzoic acid. Food manufacturers make sodium benzoate by synthesizing the compounds, sodium hydroxide and benzoic acid, together. In addition to its use as a food preservative, sodium benzoate has other roles in food production as well.

According to the International Program on Chemical Safety, sodium benzoate is heavily used by the soft drink industry due to the demand of high-fructose corn syrup in carbonated drinks. Sodium benzoate increases the acidity of soft drinks, which also increases the intensity of flavor you get from the high-fructose corn syrup. On the back of a soda can, you can find sodium benzoate in the ingredients list as E211, which is the number assigned to it as a food additive.
FAQ
Sodium benzoate is primarily added to acidic foods to enhance their flavor. It can be found in foods such as pickles, sauces, jamsand fruit juices. Foods that contain vinegar, such as salad dressings, typically contain very high levels of sodium benzoate.Benzene, a precursor to sodium benzoate, can be found in very small amounts naturally in some fruits, vegetables, meats, dairy products and even drinking water.
