Xanthan gum is a polysaccharide; its structure contains a cellulose backbone with branches of the sugars galactose and mannose. Like starch, xanthan also builds viscosity over a wide variety of temperatures. Recently, producers have started clarifying xanthan to make it more transparent and aid in its functionality for dysphagia patients.

Satiaxane CX™ 915 is a low dusting xanthan gum with a granule size of 90 % < 355 μm (US 45#)
Xanthan gum, a polysaccharide used in drilling fluids and in tertiary recovery, has relatively stable viscosity properties as a function of salt concentration, pH, temperature, and shear degradation.
Xanthan gum has a number of powerful properties. First, it works as an emulsifier, encouraging liquids that normally don't like one another to mix together. Second, it works as thickener, increasing the viscosity of liquids and batters. Third, it can create a creamy texture.
The viscosity is a function of the concentration of polysaccharide, pH and the composition of the salt. The increased viscosity is believed to be from cross-linking . Heating and cooling xanthan causes the molecule to be more rigid, this is believed to be from the transition from a single to a double helix .
In the absence of sediments, xanthan solutions maintained their viscosity for months. However, the solutions lost their viscosity over a period of days to weeks when in contact with site sediment. Loss of viscosity is attributed to physical and biodegradation processes.
Xanthan gum solution has the properties of low concentration and high viscosity (The viscosity of 1% solution equals to 100 times gelatin) and is a kind of efficient thickener. Xanthan gum solution has high viscosity a static or low shear rate.
Xanthan gum is mainly considered to be non-gelling and used for the control of viscosity due to the tenuous associations endowing it with weak-gel shear-thinning properties. It hydrates rapidly in cold water without lumping to give a reliable viscosity, encouraging its use as thickener, stabilizer, emulsifier and foaming agent.
The viscosity of xanthan gum solutions decreases with higher shear rates; this is called shear thinning or pseudoplasticity. This means that a product subjected to shear, whether from mixing, shaking or even chewing, will thin out, but, once the shear forces are removed, the food will thicken back up.
which explains why the viscosity of the xanthan gum solution is insensitive to temperature changes below the transition temperature. As a result of the rigid helical conformation, xanthan gum viscosity is relatively insensitive to differences in ionic strength and pH. In contrast, other polysaccharides
Xanthan gum is soluble in cold water, and it exhibits very high viscosity at low shear rate range and relatively low viscosity at high shear rate range. Strong synergism is observed between xanthan gum and some mannan-containing polysaccharides, such as galactomannans and glucomannans (Izydorczyk et al., 2005).
The viscosity of xanthan gum solution is affected by both the dissolving temperature and the measured solution temperature. Like most kinds of solutions, it decreases as the solution temperature rises and the change process is completely reversible in temperature 10°～80°.
Mixtures of xanthan and guar gum showed a higher combined viscosity than that occurring in each separate gum. This synergistic interaction was affected by the gum ratio in the mixture and dissolution temperature of both gums.
Xanthan gum has a synergistic effect in combination with locust bean gum and konjac (gel formation) as well as with guar gum (higher viscosity). Thanks to the unique rheological and synergistic properties of its aqueous solutions, xanthan gum is used in many applications as a suspending agent and emulsion stabilizer, a foam enhancer or an ...
Xanthan gum consists of chains of cellulose monosaccharides and oligosaccharides and is an anionic biopolymer. The key properties of xanthan gum are its extreme pseudoplasticity and its very good thermal and pH stability.
Xanthan Gum Properties Xanthan gum is a viscose xanthan gel that is an effective thickening vegetable gum for increasing thickness in various cooking uses. Any kind shear of force, like shaking, mixing or blending results in lesser viscosity.
Xanthan gum E415 Properties. Xanthan gum E415 is very resistant to pH-variations and is therefore stable in both alkaline and acidic conditions. The thermal stability of xanthan gum is usually superior to most other water-soluble hydrocolloids.
Xanthan gum as is with all hydrocolloids bind water. The viscosity of xanthan gum is stable at low pH values and at high temperatures for a long period of time and is not affected by the addition of large amounts of salt.
1459, or xanthan gum, produced by the bacterium Xanthomonas campestris NRRL B-1459 was extensively studied because of its properties that would allow it to supplement other known natural and synthetic water-soluble gums.
Xanthan gum is an extracellular polysaccharide secreted by the micro-organism Xanthomonas campestris. Xanthan gum is soluble in cold water and solutions exhibit highly pseudoplastic flow. Its viscosity has excellent stability over a wide pH and temperature range and the polysaccharide is resistant to enzymatic degradation. Xanthan

The xanthan polymer network makes VANZAN® Xanthan Gum a highly efficient thickener for water- based systems. Concentrations as low as 0.1% by weight will cause a significant increase in viscosity.
Xanthan gum exhibits extraordinary and useful properties, for example high viscosity at low concentrations, little change in viscosity at varying temperatures, and excellent stability over a wide pH range. It also provides good freeze-thaw stability and shows remarkable suspension characteristics.
Xanthan Gum is a gum obtained by microbial fermentation from the xanthomonas campestris organism. it is very stable to viscosity change over varying temperatures, ph, and salt concentrations. it is also very pseudoplastic which results in a decrease in viscosity with increasing shear. it reacts synergistically with guar gum and tara gum to ...
Xanthan Gum also exhibits excellent freeze-thaw stability. Viscosity. Viscosity values are generally not affected by changes in pH, addition of salt and thermal changes for extended periods of time whereas other hydrocolloids break down under the same conditions.
Xanthan gum, also called xanthan, is a polysaccharide water-soluble gum used for its thickening and stabilizing properties. It is a viscosity builder, humectant and textural enhancer. It binds to more water to create a moister product.
Some properties of xanthan gum in aqueous solutions: effect of temperature and pH. Zeta potential data determined for XG solutions in water in the temperature range of 15–45 °C corroborated with the results obtained from the viscometric investigations suggest the occurence of conformational changes above 36 °C.
Xanthan gum has a number of powerful properties. First, it works as an emulsifier, encouraging liquids that normally don't like one another to mix together. Second, it works as thickener, increasing the viscosity of liquids and batters.
There's a wide difference between uses of xanthan gum as an ingredient digested as a dietary fiber and it having laxative properties. Xanthan gum is mainly used in food manufacturing in small amounts (mg quantities) to improve viscosity of liquids or the texture of foods.
