1. Product introduction
Xanthan gum is usually made from corn starch. It is an acidic extracellular heteropolysaccharide composed of Xanthomonas campestris of black rot of Brassica napus with carbohydrates as the main raw material and aerobic fermentation bioengineering technology.

3. Purpose and function
Xanthan gum solution has the characteristics of low concentration and high viscosity (the viscosity of 1% aqueous solution is 100 times that of gelatin). It is an efficient thickener. Xanthan gum can dissolve rapidly in water and has good water solubility. Especially it can be dissolved in cold water, which can save the complicated processing process and is convenient to use. Xanthan gum solution can be miscible with many salt solutions (potassium salt, sodium salt, calcium salt, magnesium salt, etc.), and the viscosity is not affected. Under the condition of high salt concentration, even in saturated salt solution, it still maintains its solubility without precipitation and flocculation, and its viscosity is almost unaffected.
4. Use guide
Dosage: 0.1-0.5%. Because of its strong hydrophilicity, if the direct addition of water is small and the stirring is not sufficient, the outer layer absorbs water and expands into micelles, which will prevent the water from entering the inner layer, thus affecting the role. Therefore, we must pay attention to the feeding speed and the best high-speed stirring and shearing.
