Xanthan Gum And Sodium Benzoate

Xanthan gum is a polysaccharide, a type of carbohydrate, produced by the fermentation of sugar by the bacterium *Xanthomonas campestris*. Sodium benzoate is a salt of benzoic acid, an organic compound found naturally in some fruits and spices. It is typically produced synthetically for food use.

Xanthan gum is used as a thickener and stabilizer in foods like salad dressings, sauces, and baked goods to improve texture and prevent ingredients from separating. Sodium benzoate is used as a preservative to inhibit the growth of mold, yeast, and bacteria, commonly found in acidic foods and beverages such as sodas, pickles, and jams.

Xanthan gum is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. Sodium benzoate is also GRAS and approved as a food additive by the FDA. Both substances 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. In the presence of Vitamin C, sodium benzoate can form small amounts of benzene, a carcinogen, particularly when exposed to heat or light; however, levels are generally very low and considered safe by regulatory agencies.
