Abstract
A process for the preparation of a dispersion of starch in an hydroxylic liquid, the process comprising introducing a feed starch and an hydroxylic liquid to an extruder, and applying shear forces in the extruder to the starch and the liquid under conditions sufficient to prepare a stable dispersion of starch particles in the hydroxylic liquid.
Claims12
A process for the preparation of a dispersion of starch in a hydroxylic liquid, the process comprising:
- introducing a feed starch and aft hydroxylic liquid selected from water, an alcohol, and mixtures thereof, to an extruder, and
- applying shear forces in the extruder to the starch and the liquid in the substantial absence of a cross-linker under conditions sufficient to prepare a stable dispersion of starch particles in the hydroxylic liquid, with the proviso that the dispersion has a solids content of at least 15%.
