Xanthan gum is a type of soluble fiber that is derived from the fermentation of carbohydrates by the bacteria Xanthomonas campestris. It is commonly used as a thickener, stabilizer, and emulsifier in a wide range of food products, including salad dressings, sauces, and baked goods. It is also used in some personal care products, such as toothpaste and lotion.
In protein powders, xanthan gum is used as a thickener and stabilizer, helping to improve texture and consistency. It can also help to prevent ingredients from separating and settling to the bottom of the container.
Xanthan gum is generally recognized as safe by regulatory agencies and is widely used in the food industry.
