E 212 (Potassium Benzoate), the potassium salt of benzoic acid, is typically used by food manufacturers as a chemical preservative. 
E 212 (Potassium Benzoate)'s sometimes used in place of a related preservative -- sodium benzoate -- to reduce the food's sodium content. 
E 212 (Potassium Benzoate) helps fight food spoilage, and it can contribute to food's flavor, but like any food additive, it can cause allergic reactions in some people.

According to the U.S. Food and Drug Administration, potassium benzoate is "generally recognized as safe" and approved for use as a preservative as well as a flavoring agent. Adding just a small amount can help prevent the growth of mold, yeast and certain bacteria in foods. Because the compound imparts a tang to certain foods, it can also be used as a flavoring agent.
