Thickeners: Xanthan Gum

Xanthan gum is a polysaccharide, a type of carbohydrate, produced by the fermentation of sugar by the bacterium *Xanthomonas campestris*. It is then purified, dried, and ground into a fine powder. It is a common food additive used to improve texture and consistency.

Manufacturers add xanthan gum to foods to thicken them, stabilize emulsions, and improve texture. It is often found in salad dressings, sauces, baked goods, and dairy products like ice cream and yogurt, helping to prevent separation and create a smoother mouthfeel.

Xanthan gum is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food additive. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated xanthan gum. At typical consumption levels, it is not associated with adverse health effects. Some studies suggest it may help with satiety and blood sugar control, but more research is needed.
