魔芋干制色泽褐变规律与模型的研究

Regularity and Model of Konjak Co1or-Browning under Hot Air Drying

采用二次正交旋转组合试验设计，在２３种工况下模拟魔芋片的热风干燥过程，研究了干燥介质温度、流动速度与切片厚度３因素对产品色泽的影响规律，得到定量描述产品色泽变化的数学模型和保证最佳产品色泽的干燥工艺参数。

With the method of quadraticrotation-orthogonality the effects of the airtemperature,air speed and sliced thickness on the color of the dried konjak produce havebeen studied under 23 different working condition with simulating hot air drying tests.As a result,the mathematical model,which quantitatively explains produce colorchanges,and drying processing parameters,which ensures the optimum produce color,have been obtained.
