Xanthan

Descripción

Xanthan gum, also known as yellow gum and xanthan gum, is an extracellular acidic heteropolysaccharide produce by the fermentation of Xanthomonas. It has unique physical and chemical properties, which makes it widely used in many fields. The following are the main uses and functions of it:

1. Food industry

In the food industry, xanthan gum is often use for  a stabilizer, emulsifier, suspending agent, thickener and processing aid. It can control the rheology, structure, flavor and appearance of the product, and its pseudoplasticity ensures a good taste. It is widely use in salad dressings, bread, dairy products. Frozen foods, beverages, condiments, brewing, candy, cakes, soups and canned foods. In addition, since it cannot be directly degrade of the human body. It is also use in low-calorie foods to reduce consumers’ calorie intake.

2. Daily chemical industry

In the daily chemical industry, xanthan gum is a good surfactant because it contains a large number of hydrophilic groups in its molecules, and has antioxidant and anti-aging effects. Therefore, most high-end cosmetics use it as its main functional ingredient. In addition, xanthan gum can also be use for a component of toothpaste to help thicken and shape, and reduce tooth surface wear.

3. Pharmaceutical industry

In the pharmaceutical industry, xanthan gum is a functional component in microcapsule drug capsules, and plays an important role in controlling drug sustained release. Its strong hydrophilicity and water retention make it have many specific applications in medical operations, such as forming a dense water film, avoiding skin infection, and alleviating thirst after radiotherapy. Studies have also shown that xanthan gum has a significant enhancing effect on the humoral immune function of mice.

4. Industrial and agricultural applications

In the petroleum industry, due to its strong pseudoplasticity. A low concentration of xanthan gum (0.5%) aqueous solution can maintain the viscosity of the drilling fluid and control its rheological properties. This makes the viscosity of the high-speed rotating drill bit extremely small. Saving power; While the relatively static drilling part maintains high viscosity, thereby preventing the well wall from collapsing. In addition, due to its excellent salt resistance and heat resistance. Xanthan gum is widely used in drilling in special environments such as the ocean and high-salt layer areas. And can use for an oil recovery agent to reduce dead oil areas and increase oil recovery rates.

5. Skin care and beauty

Xanthan gum has the effect of moisturizing and hydrating, as well as anti-aging effects. As an essential ingredient in skin care products. It can help the skin lock in moisture and form a protective barrier on the surface of the skin to resist the influence of the external environment. At the same time, the antioxidant properties of it help stimulate the production of collagen in the skin’s outer layer. Thereby delaying skin aging. However, it should be note that excessive use of it may hinder the skin’s absorption of nutrients.  leading to yellowing of the skin, clogged pores and other problems. So it should be used in moderation.

In summary, due to its versatility and stability. Xanthan gum has a wide range of applications in many fields such as food, daily chemicals, medicine, industry and agriculture. And skin care and beauty.
