摘要: 以黄瓜为实验对象,研究了-100kV/m高压静电场短时处理对黄瓜采后呼吸强度、失重率、细胞膜透性的影响。实验结果表明:短时高压静电场处理能够显著抑制黄瓜果实在采后贮藏过程中的重量损失,抑制黄瓜果皮相对电导率的上升,但是对黄瓜呼吸强度没有显著影响。经短时处理0.5、1、1.5h各组腐烂率高于对照,说明短时高压静电场处理降低了黄瓜的采后抗病性,在高压静电保鲜操作中应当避免采用短时处理。

Abstract: The effect of short time -100kV/m high voltage electrostatic field (HVEF) treatment on the post-harvest physiology of cucumber was studied in this paper. The results showed that the weight-losing of cucumber during storage was significantly controlled by short time HVEF treatment. Meanwhile the increase of the relative conductivity of cucumber peel was controlled while there was no significant difference between the respiration of cucumber under HVEF and control, which indicated that the short time HVEF treatment was not suitable to store fruit and vegetable.
