Xanthan Gum is an effective thickening agent and stabilizer to prevent ingredients from separating. It is a sugar-like compound made by mixing aged (fermented) sugars with a certain kind of bacteria.
Xanthan gum is produced by natural fermentation of corn, soy, wheat, or cabbage. The bacteria digest the sugars in these vegetables and produce a complex sugar polymer. Alcohol is added to make it drop out of solution. The xanthan gum is then dried and converted into a powder that can be used in food and other products.
