Study on decolorization process of the xylitol motherliquid
Aimed at the darker color of xylitol motherliquid after processing, the influence of the type and amount of decoloring agent, temperature, time and churning speed on the decolorization effect of xylitol motherliquid was systematically investigated in this paper. The results showed that active carbon A exhibited better decolorization effect. And the optional decolorization condition was obtained at the following condtion: the amount of the decoloring agent 2wt%～3wt%, temperature 60 ℃, time 40 min and churning speed 120 r/min. The best decolorization degree could reach up to 99.7%, meeting the needs of extracting crystal xylitol.
