微波对苦瓜叶绿素的影响

Influences of microwave on chlorophyll in Momordica Charantia L.

采用响应面分析法研究不同微波处理条件下苦瓜叶绿素含量的变化并建立相应的回归模型。结果表明,微波功率、微波处理时间对苦瓜叶绿素的影响达到极显著水平,而切片厚度和载样量影响则不明显,各因素的影响大小排列如下:微波功率、微波处理时间、切片厚度、载样量。各因素间交互作用分析表明,微波功率与微波处理时间、微波处理时间与载样量之间存在着一定的交互作用;微波功率与苦瓜切片厚度、微波功率与载样量、微波处理时间与切片厚度、切片厚度与载样量之间交互作用不明显。

Content changes of chlorophyll in Momordica Charantia L. under different microwave processing conditions were studied by response surface analysis and the corresponding regression models were also set up too. The results showed that microwave power and microwave processing time had tremely significant influences on chlorophyll, but section thickness and sample load had no significant influences. The influencing level of every factors put in order from high to low was as follows： microwave power, microwave processing time, section thickness, sample load. The interactions between the factors were as follows： there was some interaction between microwave power and microwave processing time, microwave processing time and sample load; there was no obviously interaction between microwave power and section thickness, microwave power and sample load, microwave processing time and section thickness, section thickness and sample load.
