PROBLEM TO BE SOLVED: To provide a method for thawing/refrigerating food which enables stable quality maintenance even for several days, with a simple structure and without requiring any level of skill for distinction or the like of food, and to provide a storage apparatus using the method.SOLUTION: The apparatus for thawing/refrigerating food includes: a disposition member 2 on which an object W to be stored can be boarded in an electrically-insulated condition an earth electrode 3 which is provided in a condition of being electrically insulated from the disposition member 2 and a voltage-applied electrode 5 electrically insulated from the object W to be stored across the object W to be stored, and facing the earth electrode 3 in a vertical direction, so that high-frequency alternating voltage set to 500-1,500 V is applied between both of the electrodes 3, 5 to form an electric field.COPYRIGHT: (C)2011,JPO&INPIT【課題】簡単な構成および食材の見分けなどの熟練度を要することなく、数日間の間でも安定した品質維持が可能な解凍・冷蔵保存方法およびこれを用いる保存装置を提供する。【解決手段】保存対象物Wを電気的に絶縁した状態で搭載可能な載置部材2と、該載置部材2と電気的に絶縁状態で設けられている接地電極3と、保存対象物Wを挟んで該保存対象物Wと電気的に絶縁され、上下方向で前記接地電極3と対向する電圧印加電極5とを設け、これら両電極3、5間に500~1500Vに設定された高周波の交流電圧を印加して電界を形成することを特徴とする。【選択図】 図1
