Xanthan gum is a popular food additive that’s commonly added to foods as a thickener or stabilizer. It’s created when sugar is fermented by a special type of bacteria that produces a thick liquid that is processed into a powder. When xanthan gum powder is added to a liquid, it quickly disperses and creates a thick and stable solution. It was discovered by scientists in 1963. Since then, it has been well researched and determined safe.
