Glucose is an organic compound with the formula C6H12O6. It is the most widespread and important monosaccharide in nature and a polyhydroxyaldehyde. Pure glucose is a colorless crystal with sweet taste, but not as sweet as sucrose, easily soluble in water, easily soluble in ethanol, insoluble in ether. Natural aqueous glucose solution is optically turned to the right, so belongs to the "dextrose".

Xanthan gum is a microbial exopolysaccharide produced by Xanthomnas campestris with carbohydrates as the main raw material (such as corn starch) by fermentation technique.

Xanthan gum has a unique rheology, good water solubility, stability to heat, acid and alkali, and good compatibility with various salts. As thickener, suspension agent, emulsifier and stabilizer, it can be widely used in more than 20 industries such as food, petroleum and medicine. It is currently the largest and most commonly used microbial polysaccharide in the world.

Sucralose is a high-intensity sweetener with the formula C12H19Cl3O8. High stability, light, heat and pH stable. Slightly soluble in water, methanol and ethanol, slightly soluble in ether. The pH value of a 10%aqueous solution is 5~8.
