Objective=To study on the liquefied and saccharified craft for the dual-enzyme hydrolysis method of making injection-glucose with broken rice, and to explore the best process conditions suitable for the preparation of the liquefaction and saccharification. Methods： Used double enzyme method,and mathematical model of Michaelis-Menten equation. Chose the value of DE,the protein content, and the light transmission rate and other indicators. Results：The best grinding broken head was 60-80 mesh. Optimum amount of liquid enzyme 160U.g-1 Liquefaction process for the best pieces rice was to 60 mesh, mixing the concentration was 25% to 30%, liquefaction time was 30min, CaCl2 amount was 0.3%, pH was 6.0, temperature was 90-95℃, Hong Ying Xiang enzyme dosage was 160U/g. Optimum saccharification Hong Ying Xiang glucoamylase for the amount was 150U/g dry matter, pullulanase dosage was 0.25U/g dry matter, saccharification time was 24h, pH of 4.2, the temperature was 60℃. Conclusion：Through this study,the best craft for the liquefaction and saccharification process conditions with the broken rice was solved, and the foundation of making glucose injection with broken rice was set.
