摘要: The present invention relates to a process for the production of xylose and dissolving pulp from xylan-containing biomass, such as hardwood. The invention is based on prehydrolysis of the xylan-containing biomass with SO2 in specified conditions, followed by chromatographic fractionation, nanofiltration or precipitation crystallization of the xylose-containing prehydrolyzate to obtain a xylose product having a xylose content of at least 55% on DS. The dissolving pulp obtained from the process can be used for example for the production of viscose.

摘要: 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.

摘要: 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.

摘要: The invention relates to a process of separating compounds with a small molar mass from compounds having a molar mass less than 1.9 times that of the compounds with a small molar mass using nanofiltration. The compounds with a small molar mass have a typical molar mass less than 250 g/mol. In one embodiment of the invention, pentose sugars are separated from hexose sugars. The invention can be applied to the recovery of xylose from spent liquors and to the recovery of betaine from sugar beet pulp extracts, for example.
