Sorbic Acid And Sodium Benzoate

Sorbic acid is a naturally occurring organic compound, though it is often produced synthetically for food use. Sodium benzoate is the sodium salt of benzoic acid, which is found naturally in many plants. Both are commonly manufactured for use as preservatives in food products.

Sorbic acid and sodium benzoate are used together as antimicrobial preservatives to inhibit the growth of mold, yeast, and bacteria. They help extend the shelf life of foods and are frequently found in acidic foods like cheeses, syrups, baked goods, and beverages.

In the United States, both sorbic acid and sodium benzoate are generally recognized as safe (GRAS) by the FDA when used as preservatives. International bodies like JECFA and EFSA have also evaluated these substances. While generally considered safe at typical consumption levels, some individuals may experience allergic reactions or sensitivities, particularly to sodium benzoate, which can be a concern for those with asthma or aspirin sensitivity. Research into potential links between sodium benzoate and hyperactivity in children has yielded mixed results.
