Sorbic Acid (C6H8O2, CAS 110-44-1) and its salt Potassium Sorbate (C6H7KO2, CAS 24634-61-5) are widely used food preservatives. These compounds inhibit mold, yeast, and fungi growth, extending shelf life in foods like cheese, wine, baked goods, and dried meats. As a white crystalline powder or granules, they are effective at low concentrations (typically 0.025-0.10%) in acidic conditions (pH<6.5). Generally recognized as safe (GRAS) by FDA, they are also used in cosmetics and pharmaceuticals. Potassium sorbate is more water-soluble than sorbic acid, making it preferable for liquid applications. Both decompose at high temperatures (>150°C). (300 chars)
