Publication number: 20160286840Abstract: A method for producing a low-prolamine product from a prolamine-bearing seed. Prolamine protein is extracted from the prolamine-bearing seed with an alcoholic solvent selected for solubilizing the prolamine to produce an extraction slurry. A solids fraction in the extraction slurry is removed from a prolamine fraction. The solids fraction is desolventized to provide the low-prolamine product.Type: ApplicationFiled: April 2, 2015Publication date: October 6, 2016Inventors: Philip L. Shane, Munir Cheryan, Shaun Knapp

Patent number: 8344107Abstract: Methods and apparatus for processing corn into one or more corn products. Oil is extracted from corn or corn products or by-products with a solvent. The corn-solvent mixture is separated into streams, one of which preferably includes an extract containing at least oil and solvent, and another containing de-oiled corn solids and adsorbed solvent. Zein is separated from the de-oiled corn solids. Solvent is then separated, and the de-oiled, de-zeined, desolventized corn solids are processed to provide one or more corn products.Type: GrantFiled: July 14, 2009Date of Patent: January 1, 2013Assignee: The Board of Trustees of the University of IllinoisInventor: Munir Cheryan

Patent number: 8236929Abstract: Methods and systems for obtaining zein and/or xanthophylls in highly pure form. Zein is first extracted from corn using aqueous ethanol. Suspended corn solids are separated, and the resulting extract is purified in a single size-exclusion chromatography step to separate impurities and produce substantially purified zein. The chromatography step may simultaneously produce substantially purified xanthophylls.Type: GrantFiled: May 8, 2007Date of Patent: August 7, 2012Assignee: The Board of Trustees of the University of IllinoisInventors: Munir Cheryan, Aniket V.

Publication number: 20120141644Abstract: A corn oil production method is described that produces oil from corn germ. An alcohol solvent is used to extract oil from corn germ. The extraction mixture is separated into the deoiled germ solids and an extract containing the alcohol solvent and oil. The extract is membrane filtered by nanofiltration or reverse osmosis. The oil is retained in the retentate and the alcohol solvent passes into the permeate. The oil contained within the retentate is concentrated and purified. The alcohol used in the extraction step may be produced in-house. The de-germed corn and the de-oiled germ solids may be used to produce the alcohol.Type: ApplicationFiled: December 6, 2010Publication date: June 7, 2012Inventors: Munir Cheryan, Philip Shane, Felipe Arana

Patent number: 7767836Abstract: A process for removing oil from an agricultural substrate, including a dry grind corn. An ethanol solution with a concentration in the range of from about 90% to about 100% ethanol is mixed with the dry grind corn in a ratio of from about 10:1 to about 1:1 to form an extraction solution including the ethanol solution, oil, and corn solids. The extraction solution is separated into the corn solids and a filtrate, the filtrate including the ethanol solution and oil. The filtrate is membrane filtered, including nanofiltration, to restrain an oil concentrate from the filtrate and pass a permeate of the ethanol solution. The oil contained within the oil concentrate is purified.Type: GrantFiled: October 12, 2006Date of Patent: August 3, 2010Assignee: The Board of Trustees of the University of IllinoisInventor: Munir Cheryan

Patent number: 7481890Abstract: Method and apparatus for processing corn into one or more corn products including dextrose. In a preferred process, corn is processed and treated with solvent(s) to extract oil. The oil can be subsequently recovered using membrane technology. Zein may also be produced if the solvent is an alcohol. Starch in the deoiled meal is converted to dextrose by liquefaction and saccharification with enzymes. The reaction mixture containing the dextrose and other components is subjected to one or more unit operations such as screening, filtration, and/or membrane technology to produce one or more of corn gluten, soluble protein, dextrose, and fiber.Type: GrantFiled: August 4, 2005Date of Patent: January 27, 2009Assignee: The Board of Trustees of the University of IllinoisInventor: Munir Cheryan

Patent number: 6648978Abstract: An improved corn wet milling process is disclosed in which a first stream comprising water, starch, and protein (e.g., gluten) is generated by separating fiber from wet milled de-germed corn particles (e.g. fiber separation step). Membrane filtration (e.g. starch-protein stream thickening) is performed on the first stream, producing a first retentate and a first aqueous permeate. The first retentate (e.g. thickened starch-protein stream) is separated into a second stream and a third stream (e.g. primary starch separation step). The second stream comprises water and a majority of the starch present in the first retentate, and the third stream comprises water and a majority of the protein (e.g., gluten) present in the first retentate. This process provides an economical means of recovering a higher percentage of the available cornstarch for inclusion in high value products.Type: GrantFiled: October 15, 2001Date of Patent: November 18, 2003Assignee: A.
