Patent number: 6447615Abstract: The present invention is directed to sago fluidity starch and the use thereof. Such fluidity starches exhibit exceptionally fast gelling properties, high gel strengths, and exceptional elasticity. These properties allow for significantly reduced processing times, including reduced hold times. Further, the higher gel strength allows for reduced starch levels without loss of final product gel strength integrity or texture.Type: GrantFiled: August 10, 1999Date of Patent: September 10, 2002Assignee: National Starch and Chemical Investment Holding CorporationInventors: Douglas J. Hanchett, Tunyawat Kasemsuwan, Joseph Light, Ai-Tsing Tan

Patent number: 6413567Abstract: Physically modified starch products are prepared using pressure and heat such as by extruding starting material starch which optionally can be admixed with gums and/or surfactants. The properties of the products can be adjusted by varying the moisture content of the materials in the extruder and the temperature and pressure at a die plate provided at the discharge end of the extruder. The screw elements in the extruder are selected with the goal of using enough mixing elements at the discharge end to keep the pressure in the extruder barrel as high as possible over a short distance. The physically modified starch products are made up of partially to fully cooked starch and some raw starch particles. They are highly dispersible in cold or hot water with hot or cold swelling viscosity.Type: GrantFiled: September 8, 2000Date of Patent: July 2, 2002Assignee: Corn Products International, Inc.Inventors: Wayne Dudacek, Joyce A. Engels, J. E. Todd Giesfeldt, Gregory Vital
