“The additive is a polysaccharide gum derived from Xanthomonas campestris by a pure-culture fermentation process and purified by recovery with isopropyl alcohol. It contains D-glucose, D-mannose, and D-glucuronic acid as the dominant hexose units and is manufactured as the sodium, potassium, or calcium salt,” according to the FDA.


It is a thickening agent retrieved from the byproducts of a Xanthomonas campestris, and can prevent ingredients from separating. It gets its name from the bacteria used in the fermentation process. It is also a highly effective laxative.
