France made an electronic preservation machine. Put this machine in the fruit and vegetable storage room, so that the stored fruits and vegetables can be fresh and picked up within 75 days. This preservation machine uses negative oxygen ions and ozone generated by a high voltage negative electrostatic field to achieve the purpose of preservation. Negative oxygen ions can purify fruits and vegetables through metabolic processes, thereby reducing the respiration process of fruits and vegetables and reducing the production of fruit ripening agents. Ozone is a strong oxidant, and it is also a good disinfectant and bactericide. It can kill and eliminate microorganisms and their toxic substances on fruits and vegetables, inhibit and delay the decomposition of organic matter, thereby prolonging the storage period of fruits and vegetables.
