Abstract: Corn powder was used to prepare whole glucose powder. This study focused on the saccharification and decolourization of liquefied starch powder. The optimized technological parameters of saccharification are as follows: tempera-ture 59 ℃,60 hours,pH 4.8,amount of diastase 300 U/g and amount of pullulanuse 0.1 ASPU/ml. The optimized technological parameters of decolourization are as follows: amount of active carbon 3%,temperature 85 ℃,time 20 min and pH 4.6.

Key words: glucose, saccharification, active carbon, decolourization
