Xanthan Gum

is a polysaccharide used a food additive, produces by the fermentation if sugar or glucose, using the Xanthomonas campestries bacterium. In layman terms, it is nothing but a natural carbohydrate gum, produced by the bacteria fermented strain. It is a food additive that work as thickening agent and and emulsion stabilizer. The slimy substance formed by the bacteria is the actual element that acts as a thickener.
Xanthan gum is a unique substance commonly found in food, cosmetic and industrial additives. It falls under the category of polysaccharides (a class of carbohydrate) and is usually produced by fermentation process. During fermentation, a strain of bacteria (Xanthomonas campestris) is added to glucose or sucrose (i.e. corn sugar). This turns them into gum.
In fact, this is the very same bacteria that cause leafy vegetable to rot (i.e. black color rot in cauliflower). The bacteria play an important role and work to assist the formation of slimy gum-like substance. This substance is perceived to be a natural thickener, stabilizer, and emulsifier. Previously, some of the popular thickening agents available were guar gum or corn starch. With additional researches, it was discovered that a combination of Xanthomonas campestris and corn sugar produced a similar, highly useful and colorless substance. Today, this substance is popularly known as xanthan gum.

Use Of Xanthan Gum

It is a heavily used gum for the industrial uses in the food industry. Its thickening and binding qualities make it a very useful cooking aid food additive in bakery products and dairy uses. Some of the common uses of the xanthan gum is in ice creams, salad dressings, and gluten free breads. Let's see the primary xanthan gum uses across the food and other industries.

Dairy products like salad dressings & milk based sauces make use of xanthan gum.
Xanthan gum acts as substitute for wheat and other cereals used for making bread that is gluten free.
Xanthan gum use is not just for industrial uses, as a thickener is also used for enhanced viscosity for household kitchen uses as well. It is an easy way of thinking soya-milk rice, and non dairy soups and ice creams.
Toothpaste and some cosmetic and beauty products use xanthan gum for keeping the constituents well binded and then loosen up on shaking or mixing.
Guar xanthan combination is often used in ice creams and other frozen foods and beverages.
Xanthan gum substitute uses include substituting as a commercial thickener along egg whites for the fatty yolk emulsifier.
With its twin properties of being a skin hydrating agent as well as thickener and constituent binder, it is often used in cosmetic and beauty products like face packs and beauty gels.
Xanthan gum use in oil industry is of the important xanthan gum uses. Natural thickeners like guar or xanthan gum is added to water to increase its viscosity and then using it as a lubricant.
