Xanthan gum properties:
1. Suspension and emulsification
Xanthan gum has a good suspension effect on insoluble solids and oil droplets. Xanthan gum sol molecules can form super-bonded ribbon-like spiral copolymers, forming a fragile glue-like network structure, so it can support the shape of solid particles, droplets and bubbles, showing strong emulsification stabilization and high suspension ability.
2. Good water solubility
Xanthan gum can quickly dissolve in water and has good water solubility. Especially it can dissolve in cold water, which saves complicated processing and is convenient to use. But because it has strong hydrophilicity, if the water is added directly and the stirring is not sufficient, the outer layer will absorb water and expand into a micelle, which will prevent the water from entering the inner layer, thereby affecting its function. Therefore, it must be used correctly. Dry xanthan gum powder or mix it with salt, sugar and other dry powder auxiliary materials and slowly add it to the stirring water to make a solution for use.
3. Thickening
Xanthan gum solution has the characteristics of low concentration and high viscosity (the viscosity of 1% aqueous solution is equivalent to 100 times that of gelatin), and it is an efficient thickener.
