Xanthan gum is a high molecular weight polysaccharide with a helical structure produced through the fermentation of carbohydrates like glucose or sucrose by the Xanthomonas campestris bacterium . It is an anionic heteropolysaccharide that consists of a backbone of β-1,4-linked D-glucose units with side chains consisting of two mannose units and one glucuronic acid unit . The gum is known for its exceptional water solubility, high viscosity at low concentrations, and stability across a range of temperatures and pH levels .
Xanthan gum's pseudoplasticity, or shear-thinning behavior, means that its viscosity decreases under stress or agitation but returns to a higher viscosity when at rest. This characteristic makes it valuable in various industrial applications . It is commonly used as a thickening agent, emulsifier, and stabilizer in the food industry, particularly in products like salad dressings, baked goods, and dairy products . Xanthan gum's ability to remain stable in both cold and hot temperatures, as well as its compatibility with a wide range of other ingredients, makes it a versatile additive .
In addition to its use in food, xanthan gum has applications in the pharmaceutical industry, where it can be found in suspensions and tablets to improve consistency and stability . It is also used in personal care products like lotions and shampoos for its ability to suspend ingredients and provide a smooth texture . Furthermore, xanthan gum is utilized in industrial processes such as oil well drilling, where it helps to thicken drilling fluids and improve their performance under high-temperature and high-salinity conditions
