Process for preparing L-arabinose from pulp sugar beet pulp.

摘要

A method of preparing crystalline L-arabinose, characterized by the combination of the following steps: a) extraction of sugar beet pulp from which sugar has been extracted, in a strong alkaline solution, b) hydrolysis of the crude araban obtained with strong acid at an elevated temperature, c) neutralization and filtration of the obtained solution, d) chromatographic separation of the fraction of L-arabinose using a cation exchanger in a monovalent metal such as separation resin, e) purification solution Larabinose obtained through cation and anion exchangers and absorbent resins, and f) recovering the pure L-arabinoa as crystalline product.
