PROBLEM TO BE SOLVED: To provide a wrapping which impregnates natural hinokitiol by using only safe water without using alcohols which may affect to fresh food and to provide a production method of the same.SOLUTION: The wrapping for maintaining food freshness is produced by following steps of: creating mixture 1 by including hinokitiol of at least 500 ppm in the water pouring the mixture 1 into a pressure vessel 2 and stirring by a stirrer 3 heating the mixture 1 by a heating device 4 until its temperature reaches to 70°C in degrees centigrade from room temperature releasing heat of the mixture 1 until its temperature reaches to room temperature while maintaining stirring state pressurizing the mixture 1 and spraying to a roll-like unwoven fabric 6(or paper)by using a spraying device 5 so as to impregnate and drying. Then the unwoven fabric is wound into a roll-like state.COPYRIGHT: (C)2014,JPO&INPIT【課題】 従来の生鮮食品へ影響を与える可能性のあるアルコールを一切使用せず安全な水のみを用いて、天然ヒノキチオールを含浸した包装紙およびその製造方法を提供することを目的とする。【解決手段】 本発明の食品鮮度保持用包装紙は、水にヒノキチオールを少なくとも500ppmを含む混合液1を作成し、この混合液1を圧力容器2に入れて、撹拌機3により撹拌しながら常温より摂氏70度まで加熱装置4により加熱、撹拌状態を維持しつつ混合液を常温まで放熱し加圧して噴霧器5を用いてロール状の不織布6(または紙)に吹き付け含浸させ、乾燥させる工程を経て、ロール状に巻き取る。【選択図】図1
