- Thickening.
- Fake plasticity.
- Stability to heat.
- Stability to acid and alkali.
- Stability to salt.
- Stability to enzymatic hydrolysis.
What is the chemical composition of xanthan gum?
Xanthan gum, which is produced from aerobic fermentation by Xanthomonas campestris, is composed of a β-1,4-glycosidic bond-linked main chain and a trisaccharide side chain successively containing mannose, glucuronic acid, and mannose.

Is xanthan gum water-soluble?
Xanthan gum is a fast-hydrating water-soluble hydrocolloid that can easily be dissolved at room temperature. Continuous mixing and stirring reduce the hydration time of xanthan.
What is the pH of xanthan gum?
Why the pH of xanthan gum in aqueous solution is 7 (neutral) when it has glucuronic and pyruvic acids in its chemical structure?
What is xanthan gum write down the properties of xanthan gum?
Xanthan gum is a high-molecular weight polysaccharide produced by the microorganism Xanthomonas campestris using microbial fermentation. Xanthan gum is primarily used as a thickener, but is also the most efficient stabilizer for suspensions, emulsions, foams and solid particles in water-based formulations.
How does xanthan gum work chemistry?
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. Thanks to its water binding capacity, xanthan gum solutions exhibit good freeze/thaw stability.
What are the properties of guar gum?
It has strong hydrogen bonding properties. It has excellent thickening, Emulsion, Stabilizing and film forming properties. At very low concentration, Guar gum has excellent settling (Flocculation) properties and it acts as a filter aid. It is non ionic and maintains a constant high viscosity over a broad range of ph.
How does xanthan gum work as an emulsifier?
Xanthan, with it’s shear thinning, and high low-shear viscosity, is able to reduce the tendency of droplets to coalesce minimising the chances of emulsion separation.
Is xanthan gum emulsifier?
Xanthan gum serves two primary purposes: As a thickening agent: It is added to toothpaste and some other products to keep them uniformly thick. It is also used in industry, for example, helping to thicken drilling oil. As an emulsifier: Its ability to bind moisture means it can prevent products from separating.
What are the applications of xanthan?
Typical food applications of xanthan gum are salad dressings, sauces, gravies, dairy products, desserts, low-calorie foods and convenience foods in general. Xanthan gum is also used in cleaners, coatings, polishes and in agricultural flowables.
How does xanthan gum stabilize?
When xanthan gum powder is added to a liquid, it quickly disperses and creates a viscous and stable solution. This makes it a great thickening, suspending and stabilizing agent for many products (2). It was discovered by scientists in 1963.
