    摘要: A continuous process for producing refined sugar from juice extracted from sugarcane or other raw material comprises removing part of the impurities and part of the coloring matter in the juice by the use of a continuous carbonation process, decolorizing the juice by the use of granular active carbon, further removing the impurities and coloring matter remaining in the juice by using a combination of ion-exchange resin and ionexchange membrane electrodialysis, concentrating the purified juice, and crystallizing the concentrated juice to form refined sugar.

    摘要: An electric current is passed through a mixed solution containing a saccharide(s) and an organogermanium compound, in a compartment whose anode side is defined by an anion exchange membrane and whose cathode side is defined by a cation exchange membrane, to separate and remove said organogermanium compound. In the present invention, an organogermanium compound can be very effectively separated and recovered from a mixed solution containing a saccharide(s) and said organogermanium compound. The present invention is particularly effective for separation and recovery of an organogermanium compound from a reaction mixture obtained when a compound having an aldose structure is isomerized into a compound having a ketose structure in the presence of said organogermanium compound.
