The crystallization technology of saccharification liquid from broken rice for preparing glucose injection was optimized by central composite design and response surface methodology （RSM） with the concentration of saccharification liquid, amount of inoculating seed and crystallizing time as independent variables and the yield of glucose crystal as dependent variable. The results showed that the binomial regress equation fit the data well （r=0.916 0）. The optimal technology was as follows： the saccharification liquid was condensed to the co...
