Xanthan gum, also known as Hansheng gum, is a widely used microbial extracellular polysaccharide produced by Xanthomonas campestris using carbohydrates as the main raw material (such as corn starch) through fermentation engineering. It has unique rheological properties, good water solubility, stability to heat, acid and alkali, and good compatibility with various salts. As a thickener, suspension agent, emulsifier, and stabilizer, it can be widely used in more than 20 industries such as food, petroleum, and medicine. It is currently the largest and most widely used microbial polysaccharide in the world. 

Xanthan gum is a light yellow to white flowable powder with a slight odor. Easy to dissolve in cold and hot water, neutral solution, resistant to freezing and thawing, insoluble in ethanol. Disperse and emulsify in water to form a stable hydrophilic viscous colloid.

Xanthan gum is currently the most superior biological gum in the world that integrates thickening, suspension, emulsification, and stability. The amount of pyruvate groups at the end of the molecular side chain of xanthan gum has a significant impact on its properties. Xanthan gum has the general properties of long chain polymers, but it contains more functional groups than general polymers and exhibits unique properties under specific conditions. Its conformation in aqueous solution is diverse and exhibits different characteristics under different conditions.

1. Suspension and emulsifiable xanthan gum have good suspension effects on insoluble solids and oil droplets. Xanthan gum sol molecules can form super bonded helical copolymers, forming fragile gel like network structures, which can support the morphology of solid particles, droplets, and bubbles, demonstrating strong emulsification stability and high suspension ability.

2. Good water-soluble xanthan gum can quickly dissolve in water and has good water solubility. It can also dissolve in cold water, eliminating the complicated processing process and making it convenient to use. However, due to its strong hydrophilicity, if water is directly added without sufficient stirring, the outer layer will absorb water and expand into micelles, which will prevent water from entering the inner layer and affect its effectiveness. Therefore, it is necessary to pay attention to correct use. Mix xanthan gum dry powder or dry powder auxiliary materials such as salt and sugar, and slowly add the water being stirred to make a solution for use.

3. Thickened xanthan gum solution has the characteristic of low concentration and high viscosity (the viscosity of 1% aqueous solution is 100 times that of gelatin), making it an efficient thickener.

4. Pseudoplastic xanthan gum aqueous solution exhibits high viscosity under static or low shear conditions, and exhibits a sharp decrease in viscosity under high shear conditions, but its molecular structure remains unchanged. When the shear force is eliminated, the original viscosity is immediately restored. The relationship between shear force and viscosity is completely plastic. Xanthan gum has a very prominent pseudoplasticity, which is extremely effective in stabilizing suspensions and emulsions.

5. The viscosity of xanthan gum solution does not change significantly with temperature. Generally, polysaccharides undergo viscosity changes due to heating, but the viscosity of xanthan gum aqueous solution remains almost unchanged between 10 and 80 ºC. Even low concentration aqueous solutions exhibit stable high viscosity over a wide temperature range. 1% xanthan gum solution (containing 1% potassium chloride) was heated from 25 ºC to 120 ºC. Its viscosity only decreased by 3%.

6. The stability of xanthan gum solution to acids and bases is very stable. Its viscosity is not affected between pH 5-10, and there is a slight change in viscosity when pH is less than 4 and greater than 11. Within the range of PH3-11, the maximum viscosity is within 10% of the minimum value. Xanthan gum can be dissolved in various acid solutions, such as 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid, and 25% phosphoric acid. These Xanthan gum acid solutions are relatively stable at room temperature, and the quality of the product remains unchanged for several months. Xanthan gum can also be soluble in sodium hydroxide solution and has thickening properties. The resulting solution is very stable at room temperature. Xanthan gum can be degraded by strong oxidants such as perchloric acid and persulfuric acid, and the degradation accelerates with increasing temperature.

7. The stability of salt: Xanthan gum solution can be mixed with many salt solutions (potassium salt, sodium salt, calcium salt, magnesium salt, etc.), and its viscosity is not affected. Under high salt concentration conditions, even in saturated salt solutions, its solubility is maintained without precipitation and flocculation, and its viscosity is almost unaffected.

8. The stable double helix structure of xanthan gum endows it with strong antioxidant and anti enzymatic abilities, and many enzymes such as protease, amylases, cellulases, and hemicellulases cannot degrade xanthan gum.

Xanthan Gum in food :
xanthan gum is most often found in salad dressings and sauces. It helps to prevent oil separation by stabilizing the emulsion, although it is not an emulsifier. Xanthan gum also helps suspend solid particles, such as spices. Xanthan gum helps create the pleasant texture in many ice creams, along with guar gum and locust bean gum.

Xanthan Gum in oil industry :
In the oil industry, xanthan gum is used in large quantities, usually to thicken drilling mud. These fluids serve to carry the solids cut by the drilling bit back to the surface. Xanthan gum provides great "low end" rheology. When the circulation stops, the solids still remain suspended in the drilling fluid. The widespread use of horizontal drilling and the demand for good control of drilled solids has led to its expanded use. It has also been added to concrete poured underwater, to increase its viscosity and prevent washout.

Xanthan Gum Cosmetic Use
The cosmetic industry has also been able to see the properties of xanthan gum as a stabilizer and binder, that is, to prevent its components from separating. Xanthan gum can be found in:
• Toothpaste
• Bathroom gels
• Shampoos
• Creams and makeup
• Lotions and body ointments
