Abstract
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.
