Xanthan Gum (200 Mesh) is a natural gum used primarily as a food additive. Xanthan Gum can increase the viscosity, or thickness, of a liquid by adding in small quantities. It is ideal for making things like sauces and salad dressings as it remains thick. It can also be used in toothpaste, ice cream, cosmetics, and to replace gluten. Xanthan Gum (200 Mesh) is vegan, kosher, and gluten-free.
