Pet Food Ingredient
Xanthan Gum
Polysaccharide produced by bacterial fermentation of sugar, used as a thickener and stabiliser in wet pet food. Gives products a smooth, consistent texture and prevents separation.
Also labelled as
Regulatory status
FDA GRAS. AAFCO-permitted stabiliser.
Key notes
- —Fermentation substrate for xanthan is often corn or soy-based, so xanthan gum in a "corn-free" or "soy-free" food is technically derived from one of those crops — though the final product contains no detectable protein.
- —Occasionally flagged in raw-feeder communities; pet-food evidence of harm at normal inclusion is minimal.
Common alternatives
Common questions
Is xanthan gum bad for dogs?
No documented evidence of harm at typical pet-food inclusion. FDA GRAS and AAFCO-permitted. Xanthan is produced by bacterial fermentation of sugar (often corn or soy-based substrate), which means "corn-free" or "soy-free" foods containing xanthan gum may have trace origin from those crops — but the finished product contains no detectable protein from either.
Is this ingredient in your pet's food?
Scan the label. If it contains xanthan gum or any of the alternative names above, the scanner will flag it against your pet's allergen profile.
