Xanthan gum
Halal
- Typical source
- Bacterial fermentation
- Plain-language explanation
- E415, or xanthan gum, is a thickening agent created by fermenting sugar with the bacterium *Xanthomonas campestris*. The sugar used can come from various sources like corn, wheat, or soy, but the final product is highly purified. Major halal certification bodies universally consider xanthan gum halal because the fermentation process neutralizes the source material, making it permissible regardless of the sugar's origin.
