Publication number: 20230303723Abstract: A method for obtaining an inulin-containing composition includes providing an inulin-containing plant material, such as Cichorium intybus roots, and providing the inulin-containing plant material in particulate form, wherein the particles have a particle size distribution such that at most 45 vol % of the particles has a size ?0.15 mm, and at least 90 vol % of the particles has a size ?4.0 mm. The optionally dried particulate inulin-containing plant material is then subjected to an extraction step in which the inulin is extracted from the plant material to obtain an inulin-enriched juice and an inulin-depleted pulp, which are then separated, preferably by either vacuum filtration, pressure filtration and/or centrifugation.Type: ApplicationFiled: July 15, 2021Publication date: September 28, 2023Inventors: Benjamin LIMPENS, Linda MERTENS, Jan VAN LOO

Patent number: 10246729Abstract: A process for the recovery of betaine from a molasses comprises a conversion step, in which the molasses is subjected to the action of an enzyme having endo-inulinase activity and/or fructosyltransferase activity, to form a fructan-containing molasses (fructan-molasses); a separation step, in which the fructan-molasses is subjected to a chromatographic separation, thereby obtaining a betaine-containing fraction.Type: GrantFiled: May 12, 2011Date of Patent: April 2, 2019Assignee: TIENSE SUIKERRAFFIINADERIJ N.V.Inventors: Jan Van Loo, Wolfgang Wach

Patent number: 9896410Abstract: A process for the recovery of betaine from a raw material consisting essentially of molasses. The process includes a demineralization step, a conversion step and a separation step. In the demineralization step the overall amount of salts in the molasses is brought to a level lying below 2 wt. % (on overall dry matter). In the conversion step the molasses is subjected to the action of a fructan-forming enzyme, to form a fructan-containing molasses (fructan-molasses). Finally in the separation step, the fructan-molasses is subjected to a chromatographic separation, thereby obtaining a betaine-containing fraction. Whereby the demineralization step is executed prior to the separation step and whereby demineralization step may be executed prior to, during, or subsequent to the conversion step. The raw material may alternatively contain or consist essentially of thick juice.Type: GrantFiled: November 15, 2012Date of Patent: February 20, 2018Assignee: TIENSE SUIKERRAFFINADERIJ N.V.Inventors: Jan Van Loo, Wolfgang Wach
