Patent number: 8816068Abstract: The invention relates to an improved process for the production of a sugar alcohol from the corresponding sugar through catalytic hydrogenation. Especially, the invention relates to a process for reducing the interference of sugar-derived aldonic acids in the hydrogenation process by adjusting the hydrogenation conditions so that the activity of the catalyst is maintained. In one embodiment of the invention, the process of the invention is carried out by adjusting the hydrogenation temperature by starting the hydrogenation at a lower temperature and then gradually rising the temperature to the final hydrogenation temperature. In another embodiment of the invention, the process of the invention is carried out by adding small-molecular monocarboxylic acids to the hydrogenation solution.Type: GrantFiled: April 26, 2007Date of Patent: August 26, 2014Assignees: Schott Solar AG, Dupont Nutrition Biosciences ApsInventors: Jyrki Kuusisto, Heikki Heikkilä, Matti Tylli, Martin Golde, Teppo Riihimäki

Publication number: 20050256307Abstract: The present invention pertains to a chromatographic process for separating saccharide monomers from dimers and/or saccharide trimers from dimers. The separation is effected with a cation exchange resin. If saccharide monomers are separated from saccharide dimers the cation exchange resin has a high degree of crosslinking. If the saccharide dimers are separated from saccharide trimers the cation exchange resins has a low degree of crosslinking.Type: ApplicationFiled: February 4, 2003Publication date: November 17, 2005Inventors: Vili Ravanko, Nina Mayra, Heikki Heikkila, Hannu Koivikko, Pekka Kekki, Hannu Kalliomaki, Matti Tylli, Johanna Nygren

Patent number: 6663717Abstract: The invention relates to a method of simultaneous purification and separation of pectin and pectic sugars/oligomers from sugar beet pulp using a multi-step process in an aqueous solution. The method comprises hydrolysis of the sugar beet pulp, solids separation from the sugar beet pulp hydrolysate as well as fractionation and desalting of the aqueous solution of the sugar beet pulp hydrolysate thus obtained into a desalted solution enriched in pectin and a desalted solution enriched in pectic sugars/oligomers. The process may also comprise optional further steps, such as clarification, adsorption, concentration and further chromatographic treatment.Type: GrantFiled: March 6, 2002Date of Patent: December 16, 2003Assignee: Danisco Sugar OyInventors: Tapio Juhani Antila, Timo Väkeväinen, Christina Lindqvist, Hannu Koivikko, Matti Tylli, Juho Jumppanen, Pertti Walliander, Nina Mäyrä

Patent number: 6660099Abstract: The invention relates to chromatographic fractionation of pectin-containing vegetable material, such as sugar beet pulp. In the method of the invention, a pectin-containing hydrolysate is chromatographically separated into a pectin fraction, a salt fraction and a sugar fraction. The method is carried out by using a cation exchange resin, which is preferably in the form of a multivalent metal.Type: GrantFiled: March 6, 2002Date of Patent: December 9, 2003Assignee: Danisco Sugar OyInventors: Tapio Juhani Antila, Timo Väkeväinen, Christina Lindqvist, Hannu Koivikko, Matti Tylli, Juho Jumppanen

Patent number: 6146856Abstract: The present invention relates to a process for the simultaneous production of converted and non-converted sugar and/or non-sugar products. The process is especially adapted to the simultaneous production of isomaltulose and/or trehalulose, and betaine or invert sugar from plant derived juices. Sucrose in said juices are enzymatically converted into isomaltulose and trehalulose and the target products are separately recovered from the resulting solution. The isomaltulose may be further converted into isomalt.Type: GrantFiled: May 21, 1998Date of Patent: November 14, 2000Assignee: Xyrofin OyInventors: Heikki Heikkila, Marja-Leena Sarkki, Mirja Lindroos, Paivi Ojala, Vili Ravanko, Matti Tylli
