Xanthan gum

Xanthan gum, also known as xantan gum or xanthan, with the chemical formula (C₃₅H₄₉O₂₉ (monomer)), is an extracellular polysaccharide obtained from various Xanthomonas species through microbial fermentation.

This thickening agent is the first gum of the new generation of polysaccharides, and its building units include glucose, mannose, digluconic acid, and other acids. It is used in very small amounts in the food industry, and despite its very high molecular weight, it dissolves easily in both hot and cold water. Even minimal use can produce a highly concentrated solution. Although stirring reduces its viscosity, its pH remains unchanged.

Xanthan gum is applied in various sectors of the food industry, including soft drinks, canned foods, and solid food products.
