  • Hydrothermally modified starch
    Patent number: 10316107
    Abstract: A process for producing thermally inhibited starch is described resulting in a viscostable starch product. The process comprises providing an alkaline starch having a pH, when measured in a 20% (w/v) aqueous dispersion, between 9.1 and 11.2, adjusting the water content of the starch to between 2 and 22 wt. %, heating the starch between 130 and 190° C., especially between 140 and 180° C., for a sufficient time and at a sufficient pressure for the inhibition of the starch to be initiated before the water content has reached a level of 1 wt. % and before the pH has reached a value of 9, continuing heating the starch between 140 and 190° C. until viscostability is achieved, and cooling and optionally further processing the starch.
    Type: Grant
    Filed: September 16, 2013
    Date of Patent: June 11, 2019
    Assignee: N.V. NEDERLANDSCH OCTROOIBUREAU
    Inventors: Maurice Karel Hubertina Essers, Johannes Wilhelmus Timmermans, Jan Matthijs Jetten, Theodoor Maximiliaan Slaghek, Alida Anna Catharina Maria Oudhuis, Ricardo Nagtegaal
  • Resistant starch
    Patent number: 9783620
    Abstract: A colourless resistant starch is produced by a process comprising (i) suspending starch in a C2-C4 alcohol, in particular ethanol, in the presence of 0.01-3.0% (w/w) of acid based on the starch; (ii) heating the suspended starch at a temperature of 70-160° C., in particular 78-120° C., and (c) isolating the resulting product. The resulting starch has a resistant fraction of at least 20%.
