Benzoate is a salt or ester of benzoic acid, commonly used as a food preservative. It helps prevent the growth of mold, yeast, and some bacteria, thereby extending the shelf life of various products. In food labeling, it is often listed as sodium benzoate or potassium benzoate. In addition to its use in food, benzoate is also found in cosmetics and pharmaceuticals. It can be used in the production of certain plastics and as a flavoring agent. However, some individuals may be sensitive to benzoates, leading to allergic reactions or other health concerns.
