摘要： Disclosed herein is a method for the purification of a saccharide, characterized in that, water and a feedstock solution containing at least L-arabinose and oligosaccharide where L-arabinose and/or xylose are/is the constituting component(s) obtained by hydrolysis of plant tissues are supplied to a chromatographic apparatus of a simulated moving-bed system where a solution can be circulated in one direction in an apparatus equipped with a packed bed in which an adsorbent is filled and the solution in the packed bed is moved in one direction whereupon at least L-arabinose and oligosaccharide are separated each other and concentration distribution of each of them is formed in the packed bed, then at least a concentrated L-arabinose solution and a concentrated oligosaccharide solution are extracted from the packed bed and, in addition, an inlet for the feedstock solution, an inlet for water, an outlet for the concentrated L-arabinose solution and an outlet for the concentrated oligosaccharide solution are successively shifted to the downstream inlets or outlets along the flowing direction of the solution.

摘要翻译： 本文公开了一种纯化糖的方法，其特征在于，水和至少含有L-阿拉伯糖和寡糖的原料溶液，其中L-阿拉伯糖和/或木糖是通过水解得到的构成成分 将植物组织供给到模拟移动床系统的色谱装置中，其中溶液可以在装有填充床的装置中在一个方向上循环，其中填充有吸附剂，并且填充床中的溶液在一个方向上移动 因此至少将L-阿拉伯糖和寡糖分开，并在填充床中形成各自的浓度分布，然后从填充床中提取至少浓缩的L-阿拉伯糖溶液和浓缩的寡糖溶液，另外 ，原料溶液的入口，水的入口，浓缩的L-阿拉伯糖溶液的出口和浓缩的寡糖的出口 沿着溶液的流动方向依次移动到下游入口或出口。
