くい。(Operation) The decolorizing action of the decolorizing resin is conventionally known, and is described in, for example, "Decolorization and Deodorization Using Ion Exchanger" (Chemical Factory, Vol. 8, No. 5, pp. 83-87). I have. However, the present invention is characterized in that the decolorizing resin not only decolorizes the sugar solution but also removes weakly acidic substances at the same time, thereby improving the ion exchange efficiency in the subsequent step. That is, in the ion exchange step, the processing capacity is determined by the capacity of the anion exchange resin. But,
Strong acids are more easily adsorbed on the anion exchange resin than weak acids, and the weak acids exit the anion exchange resin before the strong acids. This means that the electric conductivity increases quickly, reaches the end point of the liquid passage earlier, and the amount of treatment decreases. Further, when the decolorizing resin is placed between the cation exchange resin and the anion exchange resin, it is difficult to ionize the weak acid in the aqueous solution after passing through the cation exchange resin, so that it is difficult to remove the weak acid in the decolorization step.
ゆえに、本発明においては、脱色工程を脱カチオン工
程の前に置くことが必要となる。Therefore, in the present invention, it is necessary to place the decolorization step before the decationization step.
