Potassium benzoate is a chemical compound commonly used as a food preservative. It is the potassium salt of benzoic acid and helps prevent the growth of mold, yeast, and some bacteria in acidic foods and beverages. This makes it particularly useful in products like soft drinks, fruit juices, and pickles. In addition to its role in food preservation, potassium benzoate is also found in some personal care products and pharmaceuticals. It is generally recognized as safe by regulatory agencies when used in appropriate amounts, but excessive consumption can lead to health concerns.
