Publication number: 20100152435Abstract: Processes for oxidation of primary alcohols or aldehydes into the corresponding carboxylic acids are provided herein, including processes for the aerobic catalytic oxidation of a hydroxyl moiety pendant to a cyclic carbohydrate to a carboxylic acid in a manner that preserves the cyclic carbohydrate structure. The oxidation processes may be performed in the absence of a transition metal catalyst, halogenated solvent and a hypochlorite reagent. The processes and compositions with and without a bromide source are provided. A liquid reaction media comprising a carboxylic acid and a catalyst composition may be combined with the reactant alcohol substrate to form a reaction media which can be pressurized at constant volume with an oxygen-containing gas under conditions of temperature and constant pressure within a reaction vessel to selectively oxidize the reactant substrate to form a carboxylic acid product.Type: ApplicationFiled: March 14, 2008Publication date: June 17, 2010Inventors: Jonathan A. Stapley, Setrak K. Tanielyan, Robert L. Augustine, Norman M. Marin Astorga, Gabriela D. Alvez Manoli

Patent number: 7727975Abstract: This invention relates to a pectin-modified resistant starch prepared by cross-linking starch with pectin by pectinesterase reaction. Such resistant starch is low amylase digestible and thus is useful in food products, including nutritional supplements, to reduce calorie content and increase fiber content. This invention also relates to a composition containing the resistant starch and a process for the preparation of the same.Type: GrantFiled: November 7, 2007Date of Patent: June 1, 2010Assignee: Food Industry Research and Development InstituteInventors: Wei-Hsien Chang, Jiing-Yang Wu, Chin-Hung Chang, Yi-Shan Cheng

Patent number: 7728156Abstract: The invention includes a method of treating a solid acid catalyst. After exposing the catalyst to a mixture containing a sugar alcohol, the catalyst is washed with an organic solvent and is then exposed to a second reaction mixture. The invention includes a process for production of anhydrosugar alcohol. A solid acid catalyst is provided to convert sugar alcohol in a first sample to an anhydrosugar alcohol. The catalyst is then washed with an organic solvent and is subsequently utilized to expose a second sample. The invention includes a method for selective production of an anhydrosugar. A solid acid catalyst is provided within a reactor and anhydrosugar alcohol is formed by flowing a starting sugar alcohol into the reactor. The acid catalyst is then exposed to an organic solvent which allows a greater amount of additional anhydrosugar to be produced than would occur without exposing the acid catalyst to the organic solvent.Type: GrantFiled: January 26, 2006Date of Patent: June 1, 2010Assignee: Battelle Memorial InstituteInventors: Jianli Hu, Johnathan E. Holladay, Xinjie Zhang, Yong Wang

Patent number: 7728125Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C. to about 150° C. and a reaction pressure ranging up to about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.Type: GrantFiled: June 24, 2008Date of Patent: June 1, 2010Assignee: Grain Processing CorporationInventors: Frank W. Barresi, Richard L. Antrim

Publication number: 20100121047Abstract: A method of hydrolyzing woody cellulosic material containing lignin and air pockets involves impregnating the woody cellulosic material a first alkali having a pH of from 10 to 14 such that the first alkali is in contact with the lignin within the woody cellulosic material. Thereafter, the woody cellulosic material is advanced through a gravity pressure vessel for the acid hydrolysis conversion of cellulosic material to sugars. In accordance with other methods, ultrasound may be introduced during impregnation or at the gravity pressure vessel or both.Type: ApplicationFiled: October 21, 2008Publication date: May 13, 2010Inventor: James Titmas
