PROBLEM TO BE SOLVED: To improve the removal performance of an aging-promoting substance by using a photocatalyst in a removing device for removing a substance that promotes aging of fruits and vegetables, such as ethylene, generated in a vegetable room, thereby improving freshness of fruits and vegetables. Maintain for a long time. SOLUTION: A photocatalyst 11, a white adsorbent 28, a removing element 23 carrying activated carbon 29 with a palladium catalyst attached thereon, and a light source 24 are mounted on the same equipment 27, and the photocatalyst 11 functions when the light source 24 is turned off. Even if it is not performed, the removal of the aging-promoting substances such as ethylene present in the vegetable compartment 5 can be continuously performed. |
