Ethylene gas modifying method, ethylene gas modifying device, and freshness keeping device for fresh agricultural product

摘要

To provide a method for irradiating ultra-violet rays a water retention member added with water droplets, generating OH radical in the water droplets and modifying ethylene gas into ethane and water through the OH radical. Water is supplied to the aeration water retention member formed with a water retention surface capable of holding water in its particle shape in such a way that the water is held on it under particle shape to cause the water retention surface to be kept in a state where the water retention surface is wetted with water droplets. Utra-violet rays are irradiated water held on the water retention surface and then the OH radicals are generated in the water droplets with energy of irradiated ultra-violet rays. Gas containing ethylene gas is aerated the water retention surface holding water containing the OH radicals and the ethylene gas contacted under an action of the OH radicals is modified into ethane and water.
