WebJan 20, 1994 · Abstract. Journal. Proceedings of SPIE – SPIE. Published: Jan 20, 1994 Xanthan gum is a polysaccharide with many industrial uses, including as a common food additive. It is an effective thickening agent, emulsifier, and stabilizer that prevents ingredients from separating. It can be produced from simple sugars using a fermentation process and derives its name from the species of bacteria used, Xanthomonas campestris.
