What is E415?

Xanthan gum is a thickening and stabilising agent produced by fermenting sugars with the bacterium Xanthomonas campestris. It is widely used to thicken sauces and to improve texture in gluten-free baking.

Produced by bacterial fermentation of a carbohydrate (often from corn/glucose), then recovered, dried and milled. The organism is a microbe, not an animal.

Why is it generally halal?

Xanthan gum is generally classified as halal because it is produced by microbial fermentation and is not animal-derived. A small number of strict reviewers ask about the fermentation medium and any processing aids; for full certainty, look for halal certification. The sugar substrate is typically plant-based.
