Bob’s red mill xanthan gum is a naturally gluten-free emulsifier sourced from the outer layer of inactive xanthomonas campestris bacteria. Use our xanthan gum as a gluten substitute in baked goods to add volume and enhance binding, or add it to sauces, gravies, dressings and dips as a thickener. A 1 tbsp. Serving has just 30 calories and contains no fat or added sugars. This 8 oz. Bag has a resealable zipper to keep the xanthan gum fresh between uses.
