Xanthan gum is glucose that has been fermented by the xanthomonas caperstis bacteria. It has no sugar, fat or protein, but has 2.6 g of fiber per teaspoon. Xanthan gum is used by the cosmetics and food industries as a thickener, emulsifier and stabilizer. It makes salad dressings that are glossy and cling to your salad without sacrificing flavor, according to Aki Kamozawa, author of “Ideas in Food: Great Recipes and Why They Work.” It also allows you to reduce or eliminate entirely the amount of oil you add to your salad dressing.
