Is e415 xanthan gum vegan?

E415 is the European food additive code for xanthan gum, a widely used thickening agent, stabilizer, and emulsifier. It is produced through the industrial fermentation of simple sugars by the bacterium Xanthomonas campestris. The carbohydrates used in the fermentation broth are typically derived from plant sources such as corn, wheat, soy, or sugar beets. Following fermentation, the resulting broth is precipitated with alcohol, dried, and milled into a fine powder. Food manufacturers frequently add xanthan gum to salad dressings, sauces, gluten-free baked goods, syrups, and plant-based dairy alternatives to create a smooth texture and prevent ingredients from separating.

E415 xanthan gum is considered vegan because it is entirely of microbial and plant origin. The manufacturing process relies on bacterial synthesis fueled by plant sugars and does not require animal tissues, animal by-products, or animal-derived processing aids. Because no animal inputs are involved in its cultivation or extraction, products containing this ingredient are suitable for a vegan diet.
