Patent number: 7815741Abstract: A reactor for hydrolytic splitting of cellulose under high pressure and heat has an inlet and outlet each with a cross-sectional area smaller than the cross-sectional area of the reactor. The pressure and heat in the reactor forms a cellulose plug within the inlet and the outlet. The inlet plug stops cellulose from escaping out the inlet. Cellulose begins to breakdown under heat, pressure, and if required an acid or a lubricant. The outlet plug slows downstream movement of cooking cellulose. Cellulose may be pre-treated by the addition of water, a weak acid, a lubricant, or a combination of the foregoing. The outer surface of the plug cooks faster than the inner core of the plug, becomes a liquefied slurry, and slides faster towards the outlet than the inner core.Type: GrantFiled: January 25, 2008Date of Patent: October 19, 2010Inventor: David A.

Patent number: 7794548Abstract: A process for preparing a starch-containing biomass particle stream having a significant percentage of fiber for processing into ethanol comprises the first step of: mixing the particle stream with a liquid solvent to dissolve at least a portion of the starch in the carbohydrate particle stream to form a carbohydrate slurry stream containing starch dissolved in the liquid solvent. This first step removes a portion of the fiber from the carbohydrate slurry stream. In a second step, the carbohydrate slurry stream is held in a settling tank to remove a further portion of the fiber. An enhancement to the process is suitable for use with shell corn or other biomass having an oil-containing germ portion and a non-germ portion comprising mainly carbohydrates and fiber. This enhancement includes the step of grinding the corn to particles of a size suitable for separating the germ particles from the non-germ particles. The germ particles are processed first to remove the oil and then to remove the carbohydrates.Type: GrantFiled: May 4, 2007Date of Patent: September 14, 2010Assignee: Crown Iron Works CompanyInventor: Floyd C.

Patent number: 5804232Abstract: The present invention relates to a process for preparing an instant rice nectar which can be preserved for long time. The instant rice nectar of the invention is prepared by the process which comprises the steps of: adding water to malt while stirring, filtrating to obtain malt extract, adding starch hydrolase to the malt extract and saccharifying, heating and chilling, filtering, and adding sugar to the filtrate so that the total sugar content reaches Brix 32 to 68; steeping nonglutinous rice in water and boiling, adding 1 to 3 times of water by weight and starch hydrolase to the resulting nectaring rice, and saccharifying; diluting the malt extract with water saccharified nectaring rice to the resulting mixture, and filling up a container with rice nectar thus produced and sealing; and, putting the container filled with the rice nectar in a retort chamber and sterilizing.Type: GrantFiled: September 29, 1995Date of Patent: September 8, 1998Assignee: Vilac Company Ltd.Inventors: Jung-Man Kim, Bong-Jae Lee, Joung-Yeoul Lee, Sang-Hwan Han, Kwang-Ho Lee

Thermally-inhibited pregelatinized non-granular starches and flours and process for their production
Patent number: 5720822Abstract: 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: June 7, 1995Date of Patent: February 24, 1998Assignee: National Starch and Chemical Investment Holding CorporationInventors: Roger Jeffcoat, Chung-Wai Chiu, Manish B.

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. Shah, David J. Thomas, Chung-Wai Chiu, Roger Jeffcoat, Douglas J. Hanchett

Patent number: 5674322Abstract: In the process, a starch-containing suspension 1 is divided at admixture of washing liquid 5 in a centrifuge "A" into starch-containing concentrate 2, a first liquid phase 3 with primarily dissolved substances and a second liquid phase 4 with primarily undissolved substances. The first liquid phase 3 is especially suitable as washing liquid in counterflow washing processes as it contains no obstructive undissolved substances. Also, the disposal of this liquid phase is simpler. The second liquid phase 4 with the undissolved substances is generated in higher concentration compared to conventional processes so that the processing of this phase is less cumbersome.Type: GrantFiled: May 31, 1995Date of Patent: October 7, 1997Assignee: Westfalia Separator AGInventor: Herbert Kunz

Patent number: 5614243Abstract: A novel starch-based texturizing agent, methods of manufacture and food formulations containing the texturizing agent. The texturizing agent comprises an insoluble microparticle (e.g., titanium dioxide), a gum (e.g., xanthan gum) and starch (e.g., pregelatinized starch) in the form of a complex in which the insoluble microparticle has been stabilized or entrapped therein. The texturizing agent can be used in low fat and fat-free foods, including mayonnaise, edible spreads such as margarines, salad dressing, mousse, cottage cheese dressing, sour cream, ice cream, yogurt and cream cheese.Type: GrantFiled: March 30, 1995Date of Patent: March 25, 1997Assignee: Opta Food Ingredients, Inc.Inventors: John M. Dunn, Eugene T. Finocchiaro

Patent number: 5605577Abstract: A process wherein a grain flour is treated to remove proteins is described. The process uses ethanol and water for the extraction at acid or basic pH's and optionally heating with or without a reducing agent. The remaining solution is then used to form edible and biodegradable films by casting on a surface.Type: GrantFiled: November 28, 1995Date of Patent: February 25, 1997Assignee: Board of Trustees operating Michigan State UniversityInventors: Luis M. Rayas, Perry K.W. Ng
