Abstract
The present invention relates to a preservation method and preservation apparatus which are suitable for preserving perishable goods for a long period of time. A method of the present invention is characterized by removing from the refrigerating chamber such harmful aging substances as ethylene or volatile base nitrogen triethylamine which are released from the perishable goods being preserved in a refrigerating chamber and which cause additional maturation and aging. In order to realize this method, an apparatus of the present invention is characterized by comprising adsorption materials which have adsorptivity to adsorb these harmful aging substances and are disposed in the refrigerating chamber for preserving the perishable goods. Since the above-described method and apparatus of the present invention can remove the harmful aging substances released from the perishable goods from the refrigerating chamber, it enables the safe prevention of the additional maturation and aging of the perishable goods which would be caused by the harmful aging substances. In addition, the apparatus of the invention is partitioned by a perforated plate into the cold-air blowout holes of a cooling un…
