Embodiment two,

This embodiment provides a fresh-keeping method for an assembled electric field fresh-keeping store, comprising the following steps:

Its working principle is: the fruits and vegetables picked from the field are preliminarily selected, put into plastic baskets, and fully pre-cooled, then placed on the shelf 4, close the warehouse door 5, and set the fresh-keeping temperature and humidity of the fruits and vegetables. The temperature range is 0- 10°C, humidity range 50%-100%, turn on the refrigeration button and the electric field generator button, the electric field treatment controls the charge of the electrode plate 3 by adjusting the electric field generator 1, and the charged ions finally act on the surface of the fruits and vegetables to sterilize and keep fresh Function, the assembled electric field fresh-keeping warehouse can sterilize the warehouse body and fruits and vegetables at the same time, inhibit the growth of microorganisms in the warehouse, and at the same time decompose the ethylene produced by fruits and vegetables, slowing down the ripening of fruits and vegetables.

The invention has the advantages of one-time use for long-term use, no pollution, and can maintain the nutrition and quality of fruits and vegetables to the maximum extent. After the fruits and vegetables are picked, there will be some microorganisms and bacteria on the surface that cause the fruits and vegetables to rot. Under the action of the electrostatic field, these microorganisms and bacteria will be inactivated to delay the rot of fruits and vegetables, and play a role in preserving freshness.

The preservation effect of electric field on fruits and vegetables is mainly due to the fact that the electrostatic field changes the transmembrane potential of the fruit and vegetable cell membrane, thereby affecting the physiological metabolism of the fruit; the bioelectric field inside the fruit and vegetable affects the electron transfer in the respiratory system, slows down the redox reaction in the organism, and thus Guarantee the freshness and storage of the fruit; the external energy field can cause the water to resonate, causing changes in the water structure and the combination state of water and enzymes, which eventually lead to the inactivation of the enzymes.

Therefore, the purpose of fresh-keeping can be achieved by using electric field treatment, and the assembled electric field fresh-keeping store is easy to install and maintain, and can be applied and promoted.
