What is it?
Sorbic acid (C6H8O2) is a natural preservative that comes from the rowan berries, Sorbus aucuparia (family Rosaceae). It is also prepared synthetically. It inhibits growth of fungi, yeast, mold and some bacteria and is nearly nontoxic to humans. Sorbic acid is safe to use in a wide range of foods, drugs, and cosmetic products. Sorbic acid and its salts, sodium sorbate, potassium sorbate and calcium sorbate are often used in food products as preservatives.
