Patent number: 10316107Abstract: 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: GrantFiled: September 16, 2013Date of Patent: June 11, 2019Assignee: N.V.

Patent number: 9435077Abstract: The invention is related to a method for processing biomass derived from plants or animals, comprising the steps of: a. pre treating said material with an aqueous solution of acid or base; b. subsequently passaging saturated or super heated steam through said material, wherein the water activity of the process is controlled by means of temperature and pressure of the super heated steam to be less than 1, preferably less than 0.8, more preferably in the range of 0.4-0.8. With such a process it is possible to disintegrate or make more accessible for subsequent treatments the lignocellulose from lignocellulose containing materials, like wood or other plant material, chitin from exoskeletons from Crustacea like crabs and shrimps, and proteins such as keratin from pig hair or chicken feather, for further derivation, like acylation, oxidation, etherification, carboxymethylation or esterification, or further enzymatic hydrolysis, and/or for production of chemicals, e.g.Type: GrantFiled: December 10, 2010Date of Patent: September 6, 2016Assignee: NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNOInventors: Johannes Wouterus Van Groenestijn, Jan Matthijs Jetten, Hendricus Cornelis Van Deventer, Ronald Slomp, Theodoor Maximiliaan Slaghek

Patent number: 9040571Abstract: This invention concerns a method for the preparation of a suspoemulsion formulation, which can be easily produced on an industrial scale and which allows the reproducible and effective administration of one or more water-insoluble veterinary drugs through water distribution systems. The water-insoluble veterinary drug, in finely ground form, is dispersed in a water immiscible liquid, followed by homogenization of this system into a water phase. To facilitate the preparation of a stable formulation, one or more stabilizing agents such as emulsifiers, thickeners, anti-oxidants and anti-microbials can be used. The resulting suspoemulsion shows excellent long term storage stability and a good “in use” stability after dilution in a vessel and during all handling and transport in the water distribution system.Type: GrantFiled: October 28, 2008Date of Patent: May 26, 2015Assignee: Elanco Animal Health Ireland LimitedInventors: Peter Frank Ekhart, Mario Van Wandelen, Jan Matthijs Jetten
