What it is
Xanthan gum is a polysaccharide, a type of complex carbohydrate. It is produced by the fermentation of sugar by a bacterium called *Xanthomonas campestris*. The resulting gum is then dried and milled into a fine powder.
Why it's used
Manufacturers use xanthan gum as a thickener and stabilizer in foods. It helps prevent ingredients from separating and gives a smooth texture to products like salad dressings, sauces, and baked goods. It is commonly found in gluten-free baking to provide structure.
Health notes
Xanthan gum is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is not metabolized by the body and passes through undigested. International bodies like JECFA and EFSA have evaluated xanthan gum and found it safe for consumption. At typical dietary levels, it is not associated with adverse health effects.
Allergen info
Xanthan gum is not derived from any of the nine major allergens. It does not contain gluten.
