Xanthan Gum Usage

Xanthan gum is a high molecular weight extracellular polysaccharide produced by the bacterium Xanthomonas campestris through a fermentation process. Its unique rheological properties, including high viscosity, pseudoplasticity, and stability across wide temperature and pH ranges, make it one of the most versatile hydrocolloids with applications spanning multiple industries.

Xanthan gum's performance stems from its unique molecular structure featuring a cellulosic β(1→4)-glucose backbone with trisaccharide side chains. This structure enables its exceptional stability against thermal, chemical, and enzymatic degradation. The gum is commercially available in various grades tailored for specific applications, with food-grade being the most prevalent. Its ability to maintain functionality at low concentrations (typically 0.1-1.0%) makes it economically attractive across these diverse applications
