In order to keep fruits and vegetables fresh during the airlift process, a U.S. company invented a new method of reducing oxygen and increasing nitrogen content in containers to keep fruits and vegetables fresh.
This new method uses air-conditioned containers in air transportation. The package has a special layer of film that absorbs oxygen molecules and allows nitrogen to pass through. In this way, after the air enters the box through the film, the content of nitrogen 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 time can be achieved.
