Unique pseudoplastic rheological characteristics of Xanthan gum

Xanthan gum is a polysaccharide, derived from the bacterial coat of Xanthomonas campestris, used as a food additive and rheology modifier, commonly used as a food thickening agent and a stabilizer, to prevent ingredients from separating. It is produced by fermentation of glucose, sucrose, or lactose by the Xanthomonas campestris bacterium. After a fermentation period, the polysaccharide is precipitated from a growth medium with isopropyl alcohol, dried, and ground into a fine powder. Later, it is added to a liquid medium to form the gum .

Xanthan Gum can be widely used as salt/acid resistant thickener,high efficient suspension agent and emulsifier,high viscosity filling agent in viarous food and beverang.It can not only enhance the performance of water-keeping and shape-keeping,but also improve the freeze/thaw stability and mouth-feeling of food and beverage products.Meanwhile,Xanthan Gum can extend the shelf life of products,simplifying the filling and sterilization during the course of production.Little consume of  Xanthan Gum can save lots of production cost and increase the profit rate.
