Disclosed is a cold-water soluble starch and a process for preparing same. Generally, the process comprises providing a hydroxyalkyl starch and applying a shearing force to the starch in an extruder in the presence of moisture, the force and the moisture each being sufficient to gelatinize at least substantially all of the granules of the starch to thereby form a sheared starch. The starch is heated to its gelatinization temperature after the starch has passed partially through the barrel of the extruder, with the moisture being maintained at a level sufficiently high to allow gelatinization but sufficiency low to protect the starch from becoming too sticky to extrude. The extruded starch product thus formed may be used in connection with a number of film-forming, coating, and other applications.

Disclosed is a method for preparing a modified starch hydrolysate that has a relatively reduced tendency to become sticky as compared with the unmodified starch hydrolysate. The method includes the step of compacting a starch hydrolysate, preferably via roller compaction. Also disclosed is a modified starch hydrolysate. The compacted starch hydrolysates may be transported readily, and is useful in numerous applications, including poultry feed applications.
