Abstract
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.
Claims25
A method of separating and recovering xylose from a xylose containing plant-based solution, comprising:
- performing the separation in a chromatographic separation system, which comprises one or more weak base anion exchange resins or a combination thereof 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;
- and
- recovering at least one fraction enriched in xylose wherein the recovered xylose fraction has a xylose purity of more than 45% on dissolved dry solids based on weight %.
