Potassium Sorbate And Sodium Benzoate To Maintain Freshness

Potassium sorbate and sodium benzoate are salts of sorbic acid and benzoic acid, respectively. They are often used together as preservatives because they work best at different pH levels. These compounds are produced synthetically.

These preservatives are added to foods to inhibit the growth of mold, yeast, and bacteria, helping to maintain freshness and prevent spoilage. They are commonly found in acidic foods like salad dressings, carbonated drinks, jams, jellies, and pickled vegetables.

Potassium sorbate and sodium benzoate are approved for use as food additives in the United States. The FDA lists them as Generally Recognized As Safe (GRAS) when used according to good manufacturing practices. International bodies like JECFA have evaluated these preservatives and established acceptable daily intake levels. Some studies suggest potential links to hyperactivity in children, but the evidence is mixed and not conclusive.
