摘要: 采用三因子二次回归正交旋转组合设计,对马铃薯变温压差膨化干燥工艺进行了优化研究。分析膨化温度(X1)、抽空温度(X2)和抽空时间(X3)三个变量对产品含水量(Y1)、脆度(Y2)、色泽(Y3)的影响,在此基础上由试验数据推导出描述三个指标的二次回归模型,并对变量进行响应面分析,得出最佳膨化干燥工艺条件为:膨化温度为135℃,抽空温度为125℃,抽空时间为60min。

Abstract: A central composite rotatable design (CCRD) was adopted to optimize the technology of explosion puffing drying at modified temperature and pressure for potatoes and the effect of water content after puffing temperature (X1), vacuum drying temperature(X2) and vacuum drying time(X3) on the water content after puffing(Y1), crispness(Y2), and color (Y3) were analyzed. Based on the experimental date, the quadratic regression model of three indexes were deduced, then variables were analyzed with response surface methodology (RSM). The optimal technical conditions were obtained as follows: puffing temperature was 135 ℃, vacuum drying temperature was 125 ℃ and vacuum drying time was 60 min.
