Last Updated December 20th, 2021

What is xanthan gum?

Xanthan gum is a polysaccharide (a carbohydrate) whose molecules consist of a number of sugar molecules bonded together) that is extracted from bacteria Xanthomonas campestris. The xanthan gum is obtained from sugar with the help of fermentation (the chemical breakdown of a substance by bacteria) from bacteria Xanthomonas campestris. It is broken down into a broth substance which is made solid by the addition of alcohol. This mixture is then dried and powder.

Allene Rosalind Jeanes, a renowned researcher for the U.S. Department of Agriculture, discovered xanthan gum and it was developed for commercial use. The FDA deemed it a safe food additive in 1968. Xanthan gum is produced by natural fermentation (the chemical breakdown of a substance by bacteria) of corn, soy, wheat, or cabbage. The bacteria digest the sugars in these vegetables and produce a complex sugar polymer. Alcohol is added to make it drop out of solution.

The xanthan gum is then dried and converted into a powder that can be used in the food and other products. It has also found a popular role to play in the production of gluten-free food products. Xanthan gum is found in many food, personal care, and industrial products.

The U.S. Department of Agriculture National Organic Program has added xanthan gum on the National list for use in organic processing in the U.S. Xanthan gum has also found a major area of importance in organic production. It is classified as a vegetarian product and can be deemed to be halal (permissible or lawful in traditional Islamic law) and kosher (foods are those that conform to the Jewish dietary regulations.)
