Granulated grades (500 to 1,500 µm) are easily castable and prevent dust formation.
If it's the dispersion stage that causes problems (lump formation), you can use a powder with a large particle size (150 to 250 µm, for example). Failing that (less than 100 µm, for example), the various ingredients (sugars, other powders, etc.) must be carefully premixed with the xanthan gum. Solubilization should then be rapid (a few minutes). With higher particle size powders, solubilization may take 30 min to 1 h, depending on the other components in the formulation and the stirring speed (e.g. less than 1,500 rpm).
An indicative preparation protocol might be as follows:
use a high-speed mixer (> 1,500 rpm);
Gently rain xanthan gum onto the surface of the vortex;...

Economic data
The world xanthan gum market exceeded 30,000 t in 1998, and is growing at over 5% a year. Xanthan gum is highly developed in the United States and, to a lesser extent, in Europe. Continued growth in the United States, the Americanization of food habits in Europe and innovation in the mass retail sector (detergents, cosmetics, etc.) are the driving forces behind xanthan gum's development.
