Patent number: 9777342Abstract: The invention relates to a method of separating and recovering xylose from a xylose-containing plant-based solution. The method is performed in a chromatographic separation system, which comprises one or more weak base anion exchange resins and optionally one or more other resins selected from strong acid cation exchange resins and weak acid cation exchange resins, by passing the solution through the separation system, followed by recovering at least one fraction enriched in xylose. Optionally, a rhamnose fraction may also be recovered.Type: GrantFiled: September 19, 2013Date of Patent: October 3, 2017Assignee: DUPONT NUTRITION BIOSCIENCES APSInventors: Jari Lewandowski, Nina Nurmi, Jari Mattila, Kari Laiho, Kati Kekalainen

Patent number: 7722721Abstract: The invention relates to a process of recovering galactose from a solution derived from plant-based biomass. In the process of the invention, the starting solution is subjected to one or more chromatographic fractionation steps, which may carried out with a strongly basic anion exchange resin and optionally with a strongly acid cation exchange resin, in any desired sequence, followed by recovering at least one fraction enriched in galactose. The galactose fraction thus obtained is further purified by crystallization to obtain crystalline galactose. The invention also relates to non-animal derived crystalline D-galactose.Type: GrantFiled: March 5, 2007Date of Patent: May 25, 2010Assignee: Danisco Sweeteners OyInventors: Heikki Heikkilä, Katja Häkkä, Juho Jumppanen, Pia Saari, Nina Nurmi, Vili Ravanko

Patent number: 7361273Abstract: The present invention relates to a method of separating sugars and sugar alcohols from each other. More particularly the present invention relates to the use of a weakly basic anion exchange resin in a chromatographic separation process. The advantage of the present invention compared with the prior art is that it is especially suitable for separating reducing sugars in acidic conditions as well as for example in weakly acidic conditions. The method using chromatographic separation comprises at least one step where a weakly basic anion exchange resin is used in a chromatographic column or in a part of a column.Type: GrantFiled: March 26, 2003Date of Patent: April 22, 2008Assignee: SaniscoSweetners OyInventors: Heikki Heikkilä, Päivi Sarmala, Ari Kärki, Nina Nurmi, Hannu Paananen

Publication number: 20070112187Abstract: The invention relates to a process of recovering arabinose and optionally other monosaccharides from vegetable fiber rich in heteropolymeric arabinose, such as gum arabic. Said other monosaccharides are typically selected from galactose and rhamnose. The process of the invention comprises controlled hydrolysis of the arabinose-rich vegetable fiber and fractionation of the hydrolysis product to obtain a fraction enriched in arabinose and optionally other product fractions followed by crystallization of arabinose. The invention also relates to a novel method of crystallizing arabinose from biomass-derived material. Furthermore, the invention relates to novel crystalline L-arabinose.Type: ApplicationFiled: October 29, 2004Publication date: May 17, 2007Inventors: Heikki Heikkila, Hannu Koivikko, Juha Nurmi, Jari Mattila, Pia Saari, Nina Nurmi, Paivi Sarmala, Mirja Lindroos, Jari Lewandowski

Patent number: 7037378Abstract: The invention relates to the recovery of deoxy sugars, such as fucose from biomass-derived solutions, such as spent liquors obtained from pulping processes. The invention is based on the use of chromatographic fractionation with specific column packing materials and combinations thereof. The deoxy sugar product obtained from the chromatographic fractionation may be further purified by crystallization. The invention also provides a novel crystalline fucose product and a novel process for the crystallization of fucose.Type: GrantFiled: September 24, 2003Date of Patent: May 2, 2006Assignee: Danisco Sweetners OyInventors: Juho Jumppanen, Vili Ravanko, Heikki Heikkilä, Juha Nurmi, Nina Nurmi, Pia Saari, Katja Häkkä, Jari Lewandowski
