  • Hydrophobic starch derivatives
    Patent number: 7157573
    Abstract: The invention relates to a process for preparing a hydrophobic starch, comprising etherification, esterification or amidation of a root or tuber starch comprising at least 95 wt. % of amylopectin, based on dry substance of the starch, or a derivative thereof, with a substituent comprising an alkyl chain having from 4–24 carbon atoms. The invention further relates to a hydrophobic starch obtainable by said process.

  • Oxidation of starch
    Patent number: 6822091
    Abstract: The invention relates a process of oxidizing starch wherein a root or tuber starch comprising at least 95 wt. % based on dry substance of the starch amylopectin, or a derivative therof, is treated with hydrogen peroxide in the presence of a catalyst, which catalyst comprises divalent copper ions. The present invention further relates to an oxidizable starch obtainable by a process comprising treating a starch with hydrogen peroxide in the presence of a catalyst, which catalyst comprises divalent copper ions.

  • Oxidation of starch
    Patent number: 6777548
    Abstract: The invention relates to a process for the oxidation of starch, wherein a root or tuber starch comprising at least 95 wt. % of amylopectin, based on dry substance of the starch, is treated with an oxidizing agent and the resulting product is subjected to an alkaline treatment, said treatment comprising keeping the product for at least 15 minutes at a temperature of 20-50° C. and a pH higher than 10. The invention further relates to an oxidized starch obtainable by said process and to various applications of said oxidized starch.
    Type: Grant

  • Process for making paper
    Patent number: 6767430
    Abstract: The invention relates to a process for making paper and to the use of starch in said process. In particular, the invention relates to a process for making paper, wherein in the wet-end a cross-linked starch is added to an aqueous suspension of cellulose-based fibers, which starch has a degree of cross-linking of, measured as a FANN viscosity at 300 rpm, of less than 50 mPas, and a FANN-A value of less than 2.5.
    Type: Grant

    Assignee: Cooperatieve Verkoop-en Productievereniging van Aardappelmeel en Derivaten AVEBE B.A.
    Inventors: Thomas Albert Wielema, Jan Hendriks, Ronald Peter W. Kesselmans, Jacob Terpstra
  • Dextrinization of starch
    Patent number: 6613152
    Abstract: The invention relates to a process for preparing a starch dextrin wherein a starch comprising at least 95 wt. %, based on dry substance of the starch, of amylopectin or a derivative of said starch is dextrinized. The invention further relates to a dextrin obtainable by said process and to the use thereof as an adhesive.
    Type: Grant

    Date of Patent: September 2, 2003
    Assignee: Cooperatieve Verkoop-en Productievereniging van Aardappelmeel en Derivaten Avebe B.A.
    Inventors: Augustinus Arnoldus M. Maas, Johanuddes Cornelis P. Hopman, Ronald Peter W. Kesselmans
  • Extrusion of starch
    Publication number: 20030141637
    Abstract: The invention relates to the field of processing starch. In particular, the invention relates to a process for extruding starch to obtain a starch product having a certain intrinsic viscosity when dissolved or dispersed in water, which process requires less specific mechanical energy input than conventional extrusions of starch.
    Type: Application
