Xanthan Gum And Benzoate Of Soda

Xanthan gum is a polysaccharide, a type of carbohydrate, produced by the fermentation of sugar by the bacterium Xanthomonas campestris. Benzoate of soda, also known as sodium benzoate, is the sodium salt of benzoic acid. It is typically produced by reacting sodium hydroxide with benzoic acid.

Xanthan gum is used as a thickener and stabilizer in foods like sauces, dressings, and baked goods. Sodium benzoate is used as a preservative to inhibit the growth of mold, yeast, and bacteria in acidic foods such as salad dressings, carbonated drinks, jams, and fruit juices.

Xanthan gum is generally recognized as safe (GRAS) by the FDA for use as a food additive. Sodium benzoate is also GRAS by the FDA. Both the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated sodium benzoate. Some studies have explored potential links between sodium benzoate and hyperactivity in children, particularly when combined with artificial food colors, but research findings are mixed and inconclusive. The FDA continues to monitor scientific evidence regarding food additives.
