Xanthan gum, also known as Hansen gum, is a high molecular polysaccharide with special physical and chemical properties. For example, it has a double helix structure, and its chemical properties are very stable. Common protease, Amylase, cellulase, hemicellulase, etc. are difficult to degrade it. It is insensitive to acid, alkali, salt, and temperature. It can be dissolved in cold water and hot water, and can adapt to different application environments.

Xanthan gum is a fermented industrial product, which is mainly made of glucose, sucrose, starch, corn and other carbohydrates. In the 1960s, Xanthan gum was first commercially produced in the United States, then in France, Japan and other countries, and in China since the 1980s. At present, the major countries that can produce Xanthan gum on a large scale are the United States, China, France, Japan and Austria. China's production capacity has gradually replaced the dominance of the United States.
