Pharmaceutical grade xanthan gum experimental application, research and development small test 500g sales xanthan gum is currently the international biological glue that integrates thickening, suspension, emulsification and stabilization
.
The number of pyruvic acid groups at the end of the molecular side chain of xanthan gum has a great influence on its performance
.
Xanthan gum has the general properties of long-chain macromolecules, but it contains more functional groups than general macromolecules and will show properties under specific conditions
.
Its conformation in aqueous solution is diverse and exhibits different properties under different conditions
.
1.
Suspension and emulsification Xanthan gum has a good suspending effect on insoluble solids and oil droplets
.
Xanthan gum sol molecules can form super-bonded ribbon-shaped helical copolymers, forming a fragile glue-like network structure, so they can support the morphology of solid particles, droplets and bubbles, showing strong emulsion stabilization and high suspension.

.
2.
Good water-soluble xanthan gum can dissolve quickly in water and has good water-solubility
.
In particular, it can be dissolved in cold water, which can save complicated processing and is easy to use
.
However, due to its hydrophilicity, if water is directly added without sufficient stirring, the outer layer will absorb water and swell into micelles, which will prevent water from entering the inner layer, thus affecting the performance of the product, so it must be used correctly
.
Xanthan gum dry powder or dry powder auxiliary materials such as salt and sugar are mixed well and then slowly added to the stirring water to make a solution for use
.
3.
The 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 thickening agent
.
4.
Pseudoplastic xanthan gum aqueous solution has high viscosity under static or low shear action, and under high shear action, the viscosity drops sharply, but the molecular structure remains unchanged
.
When the shear force is removed, the original viscosity is restored immediately
.
The relationship between shear force and viscosity is completely plastic
.
The pseudoplasticity of xanthan gum is very prominent, and this pseudoplasticity is extremely effective for stabilizing suspensions and emulsions
