The United States invents a new method for keeping fruits and vegetables fresh

In order to keep fruits and vegetables fresh during transportation, a U.S. company has invented a new method for reducing the oxygen content and increasing the nitrogen content of containers to keep fruits and vegetables fresh. This method uses a new type of packing box with air-conditioning performance in transportation. This packing box has a special film that can absorb oxygen molecules and allow nitrogen to pass through. In this way, after the air enters the packing box through the film, the nitrogen content in the box can be as high as 98% or more, so that the respiration of fruits and vegetables can be slowed down, and the purpose of keeping freshness for a longer period of time can be achieved.
