Salt And Sodium Benzoate

Salt is a mineral compound, sodium chloride, found naturally in seawater and underground deposits. Sodium benzoate is a synthetic chemical made from benzoic acid, which is found naturally in some fruits and spices. This ingredient combines both substances.

This combination is primarily used as a preservative to extend the shelf life of various foods. Salt helps preserve by reducing water activity, while sodium benzoate is effective against the growth of yeasts, molds, and some bacteria, especially in acidic foods. It is commonly found in pickled vegetables, sauces, and marinades.

Both salt and sodium benzoate are Generally Recognized As Safe (GRAS) by the FDA. High intake of sodium, found in salt, is linked to increased blood pressure; the FDA Daily Value for sodium is 2,300 mg. JECFA has evaluated sodium benzoate and set an acceptable daily intake. Concerns have been raised about sodium benzoate's potential to form benzene, a carcinogen, when combined with vitamin C in some beverages, though levels are typically very low.
