Sorbic acid is a natural, organic preservative frequently used to maintain the freshness of a variety of human foods, drugs, and cosmetic products. Potassium sorbate and sorbic acid possess antifungal, and to a lesser extent antibacterial, properties. Sorbic acid reacts with other chemical compounds to make what are known as derivatives. Such derivatives include calcium sorbate, potassium sorbate, and sodium sorbate. Sorbic acid may be used in wines to prevent secondary fermentation of sugar and recontamination by yeast. The most common methods of application for dairy products includes dipping or spraying with potassium sorbate solutions for natural cheeses, and direct addition to processed cheeses. Sorbates are commonly used to extend the life of fish and shellfish. They inhibit the development of yeast and mold in the fish product. Sorbates are applied as a fungistat for prunes, pickles, relishes, maraschino cherries, olives, and figs and are used to extend the shelf life of prepared salads.
