摘要
设计了2因素(脉冲频率和电场强度)3水平的正交试验,以干燥时间为试验指标,探索脉冲电场预处理对马铃薯微波干燥特性的影响。通过直接分析和极差分析,并与未处理样品进行比较,结果表明脉冲频率比电场强度对马铃薯微波干燥时间的影响略大;其中,最优组合(40Hz,1.5kV/cm)的脉冲电场预处理可使马铃薯微波干燥的时间减少23%。
In order to research the effects of PEF pre-treated on potatoes microwave drying characteristics, two factors (pulse frequency and electric field intensity) and three levels comprehensive experiments were designed with the drying time as experiments target. Through direct analysis and rang analysis, and compared with the control samples, the resuhs from the experiments demonstrated that potatoes microwave drying time is further affected by pulse frequency than by electric field intensity; and the optimal combination 40 Hz witbl.5 kV/cm of pulsed electric field pre-treated can reduce about 23% of the potatoes microwave drying time.
