It is used to help the consistency, flavor, texture, shelf life, and appearance of many foods.  Xanthan gum also stabilizes foods helping to withstand different temperatures and pH levels and prevents foods from separating.

An allergy to xanthan gum triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

Allergy symptoms vary from one individual to the next ranging from mild to severe reactions, which can be experienced within minutes to hours after exposure. Common symptoms of a xanthan gum allergy may include one or more of the following symptoms:

  • Bloating
