Japan developed a successful anion preservation machine

An electrical appliance company of Japan has successfully developed an anion preservation machine that uses the negative oxygen ions and ozone generated by the negative electrostatic field to achieve the preservation purpose. Negative oxygen ions can inhibit the activity of enzymes in the metabolism of vegetables and fruits, and reduce the production of ethylene with ripening effect in fruits and vegetables. At the same time, ozone can also sterilize, sterilize, inhibit and delay the decomposition of organic substances, thus extending the fruits and vegetables. Storage period. With this type of fresh-keeping machine, fresh fruits and vegetables are still fresh after two months, and the freshness rate is above 95%.
