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.

Publication number: 20020009239Abstract: A plastic bag comprises opposing body panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. A reclosable zipper extending along a mouth portion formed opposite the sealed bottom of the plastic bag. The zipper is preferably free of graspable upper pull flanges in order to best accommodate a slider and inhibit operation of the zipper without the slider. The slider is mounted to the zipper for movement between a closed position and an open position. The zipper is closed while the slider is in the closed position. The zipper is opened in response to movement of the slider to the open position. To inhibit tampering with the contents of the bag, the bag includes a tamper-evident feature. In one set of embodiments, the tamper-evident feature initially maintains the slider in the closed position and allows the slider to move away from the closed position toward the open position in response to removing or breaking the tamper-evident feature.Type: ApplicationFiled: September 10, 2001Publication date: January 24, 2002Inventors: Craig E. Cappel, Vernon C. Catchman, David V. Dobreski, David J. Thomas, Toby R. Thomas, Michael W. McManus

Publication number: 20010017133Abstract: 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.

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.

Patent number: 6221420Abstract: A thermally-inhibited granular starch or flour is used as an ingredient in various foods. The thermally-inhibited starches are functionally equivalent to chemically cross-linked starches. The stashes or flours are prepared by dehydrating the starch or flour to anhydrous or substantially anhydrous (<1% moisture), preferably at a neutral or basic pH, and heat treating the dehydrated starch or flour for a time sufficient to inhibit the starch to the desired degree. The dehydration may be carried out by heating the starch, extracting the starch with a solvent, or freeze drying the starch. The starch may be pregelatinized prior to or after thermal inhibition using known methods which do not substantially rupture the starch granules.Type: GrantFiled: May 29, 1996Date of Patent: April 24, 2001Assignee: National Starch and Chemical Investment Holding CorporationInventors: David J.

Patent number: 5718770Abstract: Pregelatinized granular starches and flours are thermally inhibited by dehydrating a starch to anhydrous or substantially anhydrous and then heat treating the dehydrated starch at a temperature and for a time sufficient to inhibit the starch. The starch may be pregelatinized prior to or after the thermal inhibition using methods known in the art which retain the granular integrity. Preferably, the pH of the starch or flour is raised to 7.0 or above prior to the thermal inhibition steps. The dehydration step may be carried out by directly heating the starch, by extracting the starch with a solvent, or by freeze drying the starch. Preferably protein and/or lipids are removed prior to or after the thermal inhibition.Type: GrantFiled: January 17, 1996Date of Patent: February 17, 1998Assignee: National Starch and Chemical Investment Holding CorporationInventors: Manish B.
