摘要: 在前期电磁保鲜机理探讨的基础上,通过试验分析了电场处理下的番茄在保鲜过程中的呼吸强度、硬度及失重情况的变化规律。发现一定条件下静电场能有效地抑制番茄的呼吸、保持硬度。分析中认为静电场极有可能改变了水分子的结构,从而影响了利用水分子活化过程进行催化反应的酶分子在底物反应中的催化速率。

Abstract: Based on the previous discussion about the mechanism of preservation of fruits and vegetables byelectrostatistic field (EF), the law of breathing intensity and hardness of tomatoes in preservation processing were studed by a lot of experiments. It was found that EF can effectively restrain the breathing intensity and keep hardness of tomatoes under certain parameter condition. Analysis showed that EF affects the enzyme in the catalytic reaction most probably by changing the structure of water moleculers.
