  • Patent number: 4376824
    Abstract: A glucose/fructose syrup is produced by enzymatically isomerizing an unrefined starch hydrolysate. The hydrolysate is prepared under controlled liquefaction and saccharification conditions to provide an isomerization substrate wherein the concentrations of calcium ions and non-enzymatically generated ketose sugars are maintained at low levels.
    Type: Grant

    Inventors: Louis S. Hurst, Norman E. Lloyd
  • Patent number: 4355117
    Abstract: A process is provided wherein a fibrous ion exchange cellulose composite is prepared by agglomerating a hydrophobic polymer and fibrous cellulose and then derivatizing the cellulose to impart ion exchange properties thereto. The process is an improvement over the prior art processes wherein the composite is prepared by agglomerating the polymer with fibrous cellulose which has been converted to ion exchange cellulose prior to agglomeration.

  • Patent number: 4347322
    Abstract: Enzyme purification is carried out by contacting an impure liquid enzyme preparation containing enzyme and soluble impurities with an ion exchange material in a column to adsorb both the enzyme and impurities by the ion exchange material, adding an additional amount of the impure liquid enzyme preparation whereby the soluble impurities therein are preferentially adsorbed by the ion exchange material and the adsorbed enzyme is displaced from the ion exchange material to produce a purified liquid enzyme preparation containing higher enzyme activity than before purification. The purified enzyme is more highly adsorbed by ion exchange material when immobilizing the enzyme.

  • Patent number: 4288548
    Abstract: A glucose-containing liquor is treated with an ion exchange material in the bisulfite/sulfite form and the treated liquor contacted with immobilized glucose isomerase to convert a portion of the glucose to fructose.

  • Patent number: 4279791
    Abstract: This invention relates to removal of cerium, used as a free-radical initiator, from aqueous polymeric dispersions, particularly starch graft copolymer dispersions, by adsorbing cerium (III) onto a strong cation exchange resin, to separation of the adsorbed cerium (III) from the resin using a solution such as sodium sulfate or sodium oxalate to form a cerium (III) precipitate, and to oxidation of the separated cerium (III) to cerium (IV).
