Product Overview
Xanthan Gum is a microbial polysaccharide produced by the bacterium Xanthomonas campestris. It appears as a fine, white to off-white powder and is highly effective at increasing viscosity and stabilizing emulsions and suspensions. It is valued for its ability to maintain texture and prevent ingredient separation across a wide range of temperatures and pH levels.
