Sodium benzoate is a chemical compound commonly used as a preservative in food and beverages. It helps prevent the growth of bacteria, yeast, and fungi, thereby extending the shelf life of products. It is often found in acidic foods, such as pickles, sauces, and soft drinks. This compound is the sodium salt of benzoic acid and is generally recognized as safe when used in appropriate amounts. However, it can form benzene, a known carcinogen, when exposed to high temperatures and light, particularly in the presence of ascorbic acid (vitamin C).
