A process for preparing a starch dispersion may include combining a feed starch and an aqueous liquid to form a starch slurry. The starch slurry may be subjected to a first degradation treatment to form a first mixture. A temperature of the starch slurry during the first degradation treatment may be less than a gelation temperature. The first mixture may be heated to a temperature between the gelation temperature and a solubilization temperature. The heated first mixture may be subjected to a second degradation treatment to form a second mixture. The second mixture may be sheared to form the starch dispersion.

Process for production of high solids starch dispersion using multi-stage degradation

In one or more embodiments, the present disclosure provides for a process for preparing a dispersion of starch particles in an aqueous liquid. In one or more embodiments, the process includes introducing a feed starch and the aqueous liquid into a rotor stator mixer, maintaining the feed starch and the aqueous liquid in the rotor stator mixer at a temperature ranging from a gelation temperature to less than a solubilization temperature, and shearing the feed starch into starch particles with the rotor stator mixer to form the dispersion of starch particles in the aqueous liquid. In one or more embodiments, the starch particles produced by this process have an average particle size diameter of no larger than 2 micrometers and the dispersion has 20 to 65 weight percent of the starch particles based on a total weight of the dispersion.
