Patent number: 7244312Abstract: 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: January 22, 2002Date of Patent: July 17, 2007Assignee: National Starch and Chemical Investment Holding CorporationInventors: Douglas J.

Patent number: 6617446Abstract: The present invention is directed to cold water swellable starches exhibiting delayed viscosity development, preparation and use thereof. The cold water swellable starches are prepared using methods known in the art and then are compacted. These starches provide all the advantages of CWS starch, including texture, heavy body, glossy sheen, and viscosity. However, the rate of hydration may be controlled to delay viscosity development. Such starches may be used for a variety of industrial applications including food products, personal care products, cleansers, liquid detergents and fabric softeners, oil-well drilling, and paints and allow for easier processing of such products.Type: GrantFiled: June 3, 1999Date of Patent: September 9, 2003Assignee: National Starch and Chemical Investment Holding CorporationInventors: Andreas L.

Patent number: 6451121Abstract: Thermally-inhibited starches and flours which are functionally equivalent to chemically-crosslinked starches are prepared by a process which comprises the steps of dehydrating a granular starch or flour to anhydrous or substantially anhydrous (<1% moisture) and heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch, (e.g., 120-180° C. for up to 20 hours). Preferably the pH of the starch is adjusted to neutral or greater (e.g., pH 8-9.5) prior to the dehydration. The dehydration may be a thermal dehydration carried out simultaneously with the heat treatment or a non-thermal dehydration carried out by extraction with a solvent (e.g., ethanol) or by freeze drying.Type: GrantFiled: March 2, 2001Date of Patent: September 17, 2002Assignee: National Starch and Chemical Investment Holding CorporationInventors: Chung-Wai Chiu, Eleanor Schiermeyer, David J.

Patent number: 6261376Abstract: Thermally-inhibited, pregelatinized non-granular starches and flours are prepared by pregelatinizing the starch or flour and thermally inhibiting the starch or flour by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch. The pregelatinization may be carried out prior to or after the thermal inhibition using known methods which disrupt the granular structure such by drum drying or jet cooking and spray-drying. Preferably the starch or flour is adjusted to a pH above 7.0 prior to the thermal inhibition. The starch may be dehydrated by heating the starch in a suitable heating apparatus, by extracting the water from the starch using a solvent such as ethanol, or by freeze drying the starch. Preferably the starch or flour is treated with a solvent to remove proteins and/or lipids and thus prevent off flavors.Type: GrantFiled: November 10, 1999Date of Patent: July 17, 2001Assignee: National Starch and Chemical Investment Holding CorporationInventors: Roger Jeffcoat, Chung-Wai Chiu, Manish B.
