5. Implementation
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;...

Outlook
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.

Regulations
Xanthan gum is classified as an additive, not as an ingredient, because it cannot be assimilated by humans. It has been approved for use in the food industry since 1969 by the US Food and Drug Administration (21 CFR 172.696).
It is one of the 27 polysaccharides approved by the EEC (Directive 80/597/EEC of 29/05/80, approval since 1974 for xanthan gum), and bears the number E 415.

Standardization
The only authoritative reference standard in the industry is the Food Chemical Codex, cited in the bibliographic reference.
Main producers (in 2000)
The main producers of xanthan gum are, in descending order of tonnage:
Kelco (Monsanto – USA)
Rhodia (Melle – France)
ADM (USA)
Jungbunzlauer (Austria)
SKW Trotsberg (Germany, formerly SBI France)
Production tonnages for each of these companies are confidential and...
Future prospects
Periodically, manufacturers review the studies already carried out on new polysaccharides, and may select some whose interest had not previously been perceived. Indeed, in the light of new applications (evolving customer needs) or with the progress of studies on structure-function relationships, the screening grids for potential polysaccharides evolve. This screening must be carried out with great rigor, even courage,...
