  • Patent number: 8951416
    Abstract: The present invention relates to a method of separating betaine and at least one other component from a sugar beet based fermentation solution. The invention is based on the use of a combination of SAC resins and WAC resins in a specific order and in specified proportions in a chromatographic SMB separation system. The chromatographic separation system is preferably a single integrated SMB system comprising both SAC and WAC resin beds.
    Type: Grant

  • Patent number: 7959811
    Abstract: The present invention relates to a chromatographic separation process for fractionating solutions containing sugars, sugar alcohols, sugar acids and/or betaine by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The starting solutions are typically multicomponent plant-based extracts and hydrolysates, stillages, and fermentation products and derivatives thereof. The process prow vides improved separation capacity and separation efficiency without affecting the yield or purity of product components, such as sugars, sugar alcohols, sugar acids, and betaine. The process can especially be applied to sequential SMB separation systems.

  • Patent number: 7625728
    Abstract: Effective processes are provided for the production of xylitol and ethanol and other products from solutions derived from lignocellulose-containing material in biomass. The solutions can be hydrolyzed or partially hydrolyzed before being fermented with microbes. The fermented solution can be distilled and can be subsequently separated, such as, by chromatographic separation, membrane separation, etc. The recovered xylitol solution can be crystallized to provide pure xylitol crystals.

  • Patent number: 7361273
    Abstract: 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.

  • Patent number: 6262318
    Abstract: The invention relates to a method of producing xylitol and erythritol from arabinoxylan-containing material. According to the invention, the arabinoxylan-containing material is hydrolyzed and xylose and arabinose are separated from the obtained hydrolysate, whereafter the xylose is reduced to xylitol, and the xylitol is recovered, and the arabinose is subjected to alkaline oxidation to obtain erythronic acid which is reduced to erythritol, and the erythritol is recovered.
