Preservative Xanthan Gum

Xanthan gum is a polysaccharide, a type of carbohydrate. It is made by a fermentation process using a specific type of bacteria, *Xanthomonas campestris*, often grown on a sugar-based medium. The resulting gum is then dried and milled into a fine powder.

Xanthan gum is primarily used as a food thickener and stabilizer. It helps to prevent ingredients from separating and gives foods a smooth, consistent texture. It is commonly found in salad dressings, sauces, baked goods, and dairy products.

Xanthan gum is generally recognized as safe (GRAS) by the FDA for use in food. It is poorly digested and passes through the body largely unchanged. JECFA and EFSA have evaluated xanthan gum and found it to be safe. Some studies suggest it may help lower blood sugar and cholesterol levels, but more research is needed. High doses may cause digestive discomfort for some individuals.
