| Outline of Final Research Achievements |
In the exporting apples to Southeast Asia, the temperature change at landing causes ethylene formation, which accelerates the ripening of the apples. In response to this temperature step change from 4C at transport ship to 20C at the land, we aimed to develop a packaging box that would inhibit ethylene formation by the release of 1-methylcyclopropene (1-MCP), which is an ethylene receptor binding inhibitor, from the 1-MCP included α-CD powder-coated paper in the polystyrene box. 1-MCP was released from 1-MCP included α-CD powder at the step change of moisture concentration in the polystyrene box due to the step temperature change. In this study, apples (Orin) storages were investigated in polystyrene box containing 1-MCP-encapsulated α-CD powder-coated paper at 4C for 15 days and 20C for 15 days, and evaluated the apples. The hardness and acidity of the apples improved depending on the amount of 1-MCP-encapsulated α-CD powder on the paper.

| Academic Significance and Societal Importance of the Research Achievements |
果実を輸出する際、冷蔵保存中は果実からのエチレン発生はほとんどないが、陸揚げされた際に発生するエチレンは果実の熟成を促進する。本研究は果実の鮮度保持のための梱包箱の開発で, 果実の品質劣化を防ぎ食品ロスを抑止する技術として有用であると考えている。キイとなる技術はシクロデキストリンに包接したエチレン結合阻害剤１-メチルシクロプロペン(1-MCP)を、果実の包装箱の温度ステップ変化の際の水蒸気濃度変化に応じて徐放する特質を利用したものである。本手法はCD包接物質の水蒸気濃度に依存した徐放能を利用したもので、食品鮮度保持のために多くの応用が可能と考えている。
