  • Patent number: 8592575
    Abstract: Embodiments of the processes provided herein allow for extraction of high quality pectins from pectin-containing plant materials using oxalic acid for extraction of the pectin containing material. Generally described, the process for extracting pectin having a high degree of polymerization includes preparing an aqueous suspension of a pectin-containing plant material; adding oxalic acid and/or a water-soluble oxalate to the aqueous suspension in an amount sufficient to provide a mixture having a pH of between 3.0 and 3.6 and a total molarity of oxalate greater than a total molarity of calcium(II); heating the mixture to a temperature from about 50 to about 80° C. for a time sufficient to extract pectin from the pectin-containing plant material; and separating the extracted pectin from the mixture.

  • Patent number: 8580955
    Abstract: The present invention provides a method for purifying cellobiose which comprises the steps of (A) preparing a cellobiose-containing sugar solution; (B) increasing the rate of cellobiose present in the sugar solution relative to the total saccharides present therein up to at least 50% by mass; and (C) crystallizing cellobiose; and a method for preparing cellobiose having a high content of the ?-anomer thereof which comprises the step of drying a cellobiose-containing sugar solution having a rate of cellobiose of at least 90% by mass relative to the total saccharides present therein while maintaining the sugar solution at a temperature ranging from 80 to 95° C. These methods of the present invention permit the economical preparation of cellobiose having considerably improved purity and recovery rate, without using any complicated process. Moreover, the present invention also permits the preparation of cellobiose highly soluble in water.

  • Patent number: 8575334
    Abstract: Disclosed is a method for separating anthocyanins depleted in phenolic mixture content from fruits or vegetables feedstock containing anthocyanins and phenolic mixtures. The first step is to contact the feedstock with a cation-exchange resin at low pH for a time period effective for the resin to selectively bind with the anthocyanins. Next, the non-bound phenolic mixture is separated from the resin for recovery. The bound resin is subjected to solvent wash to release the anthocyanins for recovery.

    Abstract: The invention relates to identifying and evaluating target coding and non-coding sequences for control of plant parasitic nematodes by inhibiting one or more biological functions, and their use. The invention provides methods and compositions for identification of such sequences and for the control of a plant-parasitic nematode population. By feeding one or more recombinant double stranded RNA molecules provided by the invention to the nematode, a reduction in disease may be obtained through suppression of nematode gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and the plant cells and plants obtained thereby.

  • Patent number: 8546561
    Abstract: Methods of making glucose and/or furfural from biomass require one or more supercritical fluids that may be used to process biomass, cellulose from the biomass, and/or xylose from the biomass. Examples of supercritical fluids for use in processing biomass include ethanol, water, and carbon dioxide at a temperature and pressure above the critical points for ethanol and carbon dioxide but at a temperature and/or pressure below that of the critical point for water. A supercritical fluid containing carbon dioxide and water may be used to convert cellulose to glucose or convert xylose to furfural. The fluid has a temperature and pressure above the critical point of carbon dioxide, but at least one of the temperature and pressure is below the critical point for water.
