Product Name
Xanthan gum from Xanthomonas campestris
Description
Xanthan gum is a monospore polysaccharide produced by the fermentation of Pseudomonas sp. It is made of carbohydrates as the main raw material from the cabbage black rot Xanthomonas spp. through aerobic fermentation bioengineering technology to cut 1,6 - Glycosidic bond, after opening the branched chain, an acidic extracellular polysaccharide composed of straight chains is synthesized by 1,4-bond. The structure and conformation of xanthan gum determine the functional properties of its solution: the complex aggregated structure and intermolecular forces of xanthan gum determine that its solution has high viscosity at low shear and low concentration, and is more viscous than other polysaccharide solutions. High modulus, as well as pseudoplastic behavior; Xanthan gum has hydrogen bonds, anions, and side chains entangled in the rigid and straight molecular chains of the molecular chain to protect the main chain, so that the solution has good heat and salt resistance. It also has good stability to acid-base and enzymatic hydrolysis. Due to its excellent physical and chemical properties, including high viscosity, thixotropy, and stability of dispersions, xanthan gum has been widely used in the food industry, oil extraction, coatings, and many other fields.
