    摘要: The present invention relates to a chromatographic separation process for fractionating betaine-containing solutions by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The process provides improved separation capacity and separation efficiency without affecting the yield or purity of betaine or other products. The process can especially be applied to sequential SMB separation systems.

    摘要: 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.

    摘要: The invention relates to an improved nanofiltration process for separating and recovering components, such as sug ars and sugar alcohols from multicomponent mixtures. The process of the invention is characterized by collecting the nanofiltration retentate/permeate in several fractions with different purity, optional recycling of at least one of the collected nanofiltration retentate/permeate fractions to the nanofiltration and recovering the desired component from the nanofiltration permeate/retentate fractions by dif ferent methods. In one embodiment of the invention, the process comprises a combination of nanofiltration and chromatography.

    摘要: 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 provides 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.
