摘要：
A new enzymatic pre-Treatment method for improving milling characteristics was studied by spraying cellulases solution on brown rice. The effects of enzymatic pretreatment parameters on milling characteristics of brown rice were analyzed by response surface methodology. The optimum milling characteristic was obtained under cellulases concentration of 117.4 mg/mL, interval time of 77.2 min and temperature of 35.5 °C. Validation experiments indicated that head rice yield and milling energy consumption were respectively 4.59% higher and 32.95% lower than the values for untreated samples, 1.83% higher and 8.10% lower than those of moisture conditioning treatment. The breaking force and surface structure of the brown rice by enzymatic pre-Treatment were studied to reveal the mechanism of change for milling characteristics. © 2018 Canadian Biosystems Engineering.
