Sodium Benzoate And Potassium Sorbate To Maintain Freshness

Sodium benzoate and potassium sorbate are salts that work together as preservatives. Sodium benzoate is made from benzoic acid, which occurs naturally in some fruits. Potassium sorbate is synthesized from sorbic acid, which is produced industrially. They are commonly used in combination to prevent the growth of mold, yeast, and bacteria in foods and beverages.

These preservatives are added to foods and beverages to extend shelf life by inhibiting microbial spoilage. They are frequently found in acidic products like salad dressings, carbonated drinks, jams, jellies, and fermented products such as yogurt and sauerkraut.

Sodium benzoate and potassium sorbate are approved for use in the U.S. by the FDA and are generally recognized as safe (GRAS). Both have been evaluated by international bodies like JECFA, which has established acceptable daily intakes for each. Some studies have explored potential links between these preservatives and hyperactivity in children, but the evidence is mixed and not conclusive. They are generally considered safe when consumed within typical dietary levels.
