Sodium Benzoate And Nisin Preparation

This is a combination ingredient used as a preservative. Nisin is a natural antimicrobial peptide produced by certain strains of lactic acid bacteria. Sodium benzoate is a salt of benzoic acid, which occurs naturally in some fruits but is typically produced synthetically for food use.

This preparation is primarily used as a preservative to inhibit the growth of bacteria and mold, extending the shelf life of foods. It is commonly found in processed fruits and vegetables, such as pickles, olives, and relishes, as well as in some deli salads and dairy products.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA when used according to regulations. Nisin is also permitted for use in foods. Both have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some studies have explored potential links between sodium benzoate and hyperactivity in children, though evidence is mixed and not conclusive. It can also form benzene, a carcinogen, when combined with ascorbic acid (Vitamin C) under certain conditions, though levels are typically very low.
