Abstract: 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 succes

Abstract: Disclosed herein is a continuous manufacturing method for anhydrous crystalline maltitol comprising the following steps: (i) a heating and concentrating step where an aqueous solution containing maltitol in which maltitol is a main ingredient is continuously heated and concentrated to give a concentrated solution having a high concentration; (ii) a seed crystal adding and mixing step where the seed crystals are added to and mixed with the above concentrated solution with heating to give a massceuite containing the seed crystals; and (iii) a crystal aging step where the massceuite is subjected to disintegration, mixing, stirring and transfer in an atmosphere in which temperature and moisture are adjusted to proceed the crystallization.
