The present invention provides a system for the preservation of food and a method of application thereof For that purpose, it presents a device for capturing gases using the phenomenon known as adsorption, geared toward the configuration of a system for the preservation of food during storage and transport, although it is not limited to other applications that similarly require gas capture in closed containers. The device comprises in its most general form: a plurality of mineral layers that selectively adsorb carbon dioxide, a plurality of mineral layers that selectively adsorb ethylene gases, a plurality of mineral layers that selectively adsorb oxygen, and a plurality of mineral layers that selectively adsorb humidity.
