Sorbic Acid Preservative

Sorbic acid is a white, crystalline solid. It occurs naturally in some fruits, like rowan berries, but is typically made synthetically for food use. It is produced industrially from petrochemicals.

Sorbic acid and its salts (like potassium sorbate and calcium sorbate) are used as preservatives. They help prevent the growth of mold, yeast, and some bacteria, extending the shelf life of foods. It is commonly found in baked goods, cheeses, dried fruits, and beverages.

In the U.S., sorbic acid is generally recognized as safe (GRAS) by the FDA. It is approved for use as a food preservative. International bodies like JECFA and EFSA have evaluated sorbic acid and its salts. While generally considered safe at typical consumption levels, some individuals may experience mild allergic reactions or skin irritation. Research has not established a link between sorbic acid consumption and adverse health effects at levels found in food.
