Xanthan gum is halal. Xanthan gum, also known as Hansen's gum, is produced by the wild rape Xanthomonas campestris with carbohydrates as the main raw material (such as corn starch) by fermentation engineering of a wide range of microbial extracellular polysaccharide. The secondary structure of xanthan gum is the side chain around the backbone of the main chain reverse winding, through the hydrogen bonding dimension to form a rod-shaped double helix structure.

Xanthan gum is a light yellow to white flowable powder, slightly odor. Easily soluble in cold and hot water, solution neutral, resistant to freezing and thawing, insoluble in ethanol. When water dispersion, emulsification into a stable hydrophilic viscous colloid. Xanthan gum has a unique rheology, good water solubility, heat and acid-base stability, and a variety of salts have good compatibility, as a thickener, suspending agents, emulsifiers, stabilizers, can be widely used in food, petroleum, pharmaceuticals and other more than 20 industries, is currently the world's largest production scale and extremely wide range of uses of microbial polysaccharides.
