摘要：This study was conducted to investigate the effects of indicators (temperature and time duration) on physic-engineering properties of Wuyunjiang paddy rice variety using response surface methodology (RSM). A mathematical model was used to predict length, width, thickness, thousand kernel weight (TKW), bulk density, true density, porosity and hardness as affected by temperature (40.86, 45, 55, 65 and 69.14 °C) and time (39.29, 60, 110, 160, 180.71) each with five levels. Higher values of R~2 and Adj. R~2, non-significance of lack fit and significance of F-test demonstrated the suitability and accuracy of the model. The predicted optimum temperature and time were 62.41 °C 126.20 min, and the predicted values for length, width, thickness, TKW, bulk density, true density, porosity and hardness were 7.26 mm, 3.25 mm, 2.24 mm, 29.25 g, 696.83 kg m~(-3), 1475.21 kg m~(-3), 52.76 % and 51.74 N. The results revealed that the responses were significantly affected by the indicators and can be predicted by temperature and time duration. Central composite design of the response surface methodology was successfully used to study dependence of physic-engineering properties of paddy rice. This useful information can be implemented and utilized by the rice processing industries.
