Products Application

Xanthan gum, due to its unique properties, has extremely extensive applications in more than a dozen fields such as food, petroleum, medicine, and daily chemical products. Its commercialization level and application scope are far beyond those of any other microbial polysaccharide.
1. In the food industry: Xanthan gum is added to many foods as a stabilizer, emulsifier, suspending agent, thickener, and processing auxiliary agent. It can control the rheology, structure, flavor, and appearance of the products, and its pseudoplasticity can ensure a good taste. Therefore, it is widely used in salad dressings, bread, dairy products, frozen foods, beverages, seasonings, brewing, candies, pastries, soup stocks, and canned foods. In recent years, people in developed countries often worry about the high calorific value of food causing them to gain weight. Xanthan gum, due to its inability to be directly degraded by the human body, has dispelled this concern. In addition, according to a report from Japan in 1985, after comparing and testing eleven food additives, xanthan gum was the most effective anti-cancer agent among them.
2. In the field of daily chemical products: Xanthan gum molecules contain a large number of hydrophilic groups and is a good surfactant. It also has antioxidant and anti-aging effects. Therefore, almost all high-end cosmetics use xanthan gum as their main functional component. In addition, xanthan gum can also be used as an ingredient in toothpaste to increase viscosity and shape, and reduce tooth surface wear.
3. In the medical field: Xanthan gum is currently a functional component in the popular microcapsule drug carriers in the international market, playing an important role in controlling drug sustained-release. Due to its strong hydrophilicity and water retention properties, it also has many specific medical application aspects, such as forming a dense water film to avoid skin infection; alleviating patients' thirst after radiotherapy, etc. In addition, Li Xin and Xu Lei wrote that xanthan gum itself has a significant enhancing effect on the humoral immune function of mice.
4. Applications in industry and agriculture: In the petroleum industry, due to its strong pseudoplasticity, a 0.5% aqueous solution of xanthan gum at low concentration can maintain the viscosity of drilling fluid and control its rheological properties. Therefore, the viscosity is extremely low at the rotating part of the drill bit, saving power; while at the relatively stationary drilling part, it maintains high viscosity, thus preventing well wall collapse. And due to its excellent salt resistance and heat resistance, it is widely used in drilling in special environments such as the ocean and high-salt layer areas, and can be used as a drilling fluid for oil extraction to reduce dead oil areas and increase oil recovery rate.
