Patent number: 8951594Abstract: 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.Type: GrantFiled: June 21, 2012Date of Patent: February 10, 2015Assignee: Grain Processing CorporationInventors: Lin Wang, Pete Miller, Jeff Underwood, Tonya Armstrong, Michael Kramer, Susan Freers, Roger McPherson, E. Daniel Hubbard, Terry Andren

Patent number: 6379467Abstract: 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.Type: GrantFiled: June 15, 2000Date of Patent: April 30, 2002Assignee: Grain Processing CorporationInventors: E.

Patent number: 4566910Abstract: Starch phosphates are prepared by reacting with an alkaline starch paste while maintaining an alkaline pH a phosphate salt at a temperature of about 45.degree. to 95.degree. C. for a period of not more than about 120 minutes. Amphoteric starch phosphates are prepared by also reacting with the starch paste a cationizing agent.Type: GrantFiled: November 12, 1982Date of Patent: January 28, 1986Assignee: Grain Processing CorporationInventors: E. Daniel Hubbard, Richard D. Harvey, Mark L. Hogen

Patent number: 4554021Abstract: A process for preparing a cationic starch dispersion wherein an alkaline, gelatinized starch is reacted with a cationic reagent either concurrently with, or subsequently to, the cooking process resulting in a product in which the cationic reagent is chemically bound to the starch molecule. The process is conducive to on-site preparation of a cationic starch derivative which can be utilized without additional treatment as a papermaking adjunct, textile size, waste-water treatment or tailings flocculent, etc.Type: GrantFiled: May 28, 1982Date of Patent: November 19, 1985Assignee: Grain Processing CorporationInventors: Richard D. Harvey, E. Daniel Hubbard, Robert A. Meintrup

Patent number: 4373099Abstract: A process whereby a gelatinized starch having a cationic reagent chemically bound to the starch backbone and a reduced viscosity is prepared by (1) gelatinizing starch and substantially simultaneous with gelatinization reacting said treated starch with an alkyl or alkenyl amine and a water soluble oxidant or (2) simultaneously reacting an alkyl or alkenyl amine and a water soluble oxidant with a gelatinized starch. The process is conducive to the on-site preparation of a thinned cationic starch derivative which can be utilized without additional treatment as a papermaking additive, textile size, waste water treatment, tailing flocculent, etc.Type: GrantFiled: October 7, 1981Date of Patent: February 8, 1983Assignee: Grain Processing CorporationInventors: E.
