Sodium Benzoate And Calcium Disodium EDTA As Preservatives

Sodium benzoate is a salt of benzoic acid, a common organic compound found naturally in many plants. Calcium disodium EDTA (ethylenediaminetetraacetic acid) is a synthetic compound. Both are often used together in processed foods.

Sodium benzoate and calcium disodium EDTA are used as preservatives. They help prevent spoilage by inhibiting the growth of mold, yeast, and bacteria, extending the shelf life of products like salad dressings, sauces, and condiments.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. Calcium disodium EDTA is also FDA-approved for use in food. JECFA and EFSA have evaluated both substances. 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. When combined with ascorbic acid (Vitamin C), sodium benzoate can form small amounts of benzene, a potential carcinogen, which the FDA monitors.
