PROBLEM TO BE SOLVED: To provide an ethylene decomposition catalyst capable of maintaining freshness of plants or fruits and vegetables for a long period under an atmospheric temperature.SOLUTION: In a freshness retention method of plants, a catalyst manufactured by immersing a porous material into aqueous solution of a silver salt and then drying it, is inserted into a sealed container packed with fruits and vegetables, to thereby oxidize and decompose ethylene generated from the fruits and vegetables by coexisting air.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】植物や青果物の鮮度を大気温度において長期間維持することの出来るエチレン分解触媒の提供。【解決手段】銀塩の水溶液に多孔質素材を浸漬、乾燥することで製造される触媒を、青果物を詰めた密閉容器中に挿入して、青果物から発生するエチレンを共存する空気により酸化分解させる植物の鮮度保持方法。【選択図】図1
