Gum xanthan

Description

Xanthan gum is a complex carbohydrate, made from the fermentation of simple sugars by a bacterium called Xanthomonas campestris. Xanthan gum is a popular ingredient in gluten-free baking, providing the texture and consistency that is often lost without gluten. It is also used in personal care products like shampoo, toothpaste and cosmetics because of its ability to make the products thicker and more stable.

Application

1. Thickening agent: Xanthan gum is commonly used as a food additive to thicken liquids and create a desired texture in products such as salad dressings, sauces, and dairy products.
2. Stabilizer: It also acts as a stabilizer in food products, helping to prevent separation of oil and water or other ingredients.
3. Gluten-free baking: As a gluten-free alternative for wheat flour, xanthan gum can be used to provide elasticity and texture in baked goods.
4. Industrial applications: Xanthan gum is also widely used in industrial applications, such as in the production of oil and gas, paper, and textiles.
5. Personal care products: It can be found in personal care products, such as toothpaste, as a thickening agent.

Case Study

Chemical Modification of Xanthan Gum to Obtain Diverse Xanthan Gum Derivatives

Patel, Jwala, et al. RSC advances, 2020, 10(45), 27103-27136.

Xanthan Gum (XG) is known for its biocompatibility, non-toxicity and biodegradability. Further chemical modification of xanthan gum can break through its own limitations, and the obtained xanthan gum derivatives can meet the diverse needs of drug delivery, tissue engineering, oil drilling and other applications.
Synthesis of modified xanthan gum materials
· Etherified XG: The most common and widely studied XG ether derivative is O-carboxymethyl XG.
· Esterified XG: XG has also been reshaped through esterification. For example, esterification of the carboxyl group of XG with 1-bromooctane promotes hydrophobic association, thereby increasing the viscosity of XG.
· Oxidation of XG: Oxidation of XG can partially convert the glucopyranose units into aldehydes and create additional functional sites for covalent cross-linking.
· Amide Functionalized XG: The carboxyl functionality of the XG chain may be the focal point for bifunctional amine cross-linkers to establish covalent amide bonds.
· Acetal XG: The properties of XG can be modified by the formation of acetal bonds in the presence of aldehydes.
