PROBLEM TO BE SOLVED: To provide a method for imparting effect for keeping freshness of perishable foods with charged fine particle water, and concurrently preventing water content from evaporating from the surface of perishable foods.SOLUTION: Charged fine particle water is sprayed to a perishable food 1 covered with a wrap film 3, so that the resulting difference in concentration of the charged fine particle water between the inside and the outside of the wrap film 3 allows the charged fine particle water to infiltrate into the wrap film 3. Consequently the freshness of the perishable food 1 inside the wrap film can be kept.COPYRIGHT: (C)2014,JPO&INPIT【課題】生鮮食料品に対して帯電微粒子水による鮮度保持効果を及ぼすと同時に、生鮮食料品の表面から水分が蒸発することも防止する。【解決手段】ラップフィルム3で覆われた生鮮食料品1に対して帯電微粒子水を噴霧させ、ラップフィルム3の内側と外側で帯電微粒子水の濃度に差を設けることで、帯電微粒子水をラップフィルム3内に浸透させ、内部の生鮮食料品1に対して鮮度保持効果を及ぼす。【選択図】図1
