  • Solution assay method using polarimetry
    Patent number: 6939683
    Abstract: A method for the measurement of the concentration of a material such as dextran or raffinose in a solution, notably a sugar solution, includes the steps of measurement of the optical rotation of a solution sample, treatment of the sample with a reactive agent, measurement of the optical rotation of the sample after treatment to ascertain the difference that said treatment has made, and calculation of the concentration of the material by reference of said difference to a suitable standard. The reactive agent reacts with the material sufficiently to alter the optical rotation of the sample.

  • Fermentative production of isomaltulose
    Patent number: 4670387
    Abstract: Isomaltulose is produced by a process in which at least the isomaltulose-forming enzyme system of an isomaltulose-forming micro-organism is immobilized and then the immobilized enzyme system is contacted with a sucrose solution to convert at least part of the sucrose to isomaltulose.

    Date of Patent: June 2, 1987
    Assignee: Tate & Lyle Public Limited Company
    Inventors: Christopher Bucke, Peter S. J. Cheetham
  • Method of reducing dental plaque formation with products for human or animal consumption using isomaltulose sucrose substitute
    Patent number: 4587119
    Abstract: Isomaltulose is of use as a whole or partial replacement for sucrose in products for human or animal consumption.
    Type: Grant
    Filed: December 14, 1984
    Date of Patent: May 6, 1986
    Assignee: Tate & Lyle Public Limited Company
    Inventors: Christopher Bucke, Peter S. J. Cheetham
  • Production of isomaltulose
    Patent number: 4359531
    Abstract: Isomaltulose is produced by a process in which at least the isomaltulose-forming enzyme system of an isomaltulose-forming micro-organism genus Erwinia is immobilized on calcium alginate gel and then the immobilized enzyme system is contacted with a sucrose solution to convert at least part of the sucrose to isomaltulose.
