PROBLEM TO BE SOLVED: To provide a method and an apparatus for easily thawing, which: enable no breakdown of cell membranes during thawing prevent water (drip) containing taste component from flowing out maintain original state as much as possible so that taste of high grade is kept shorten thawing time and enable sterilization of pathogen.SOLUTION: A method for thawing frozen fish, shellfish and meat comprises: a step of mounting an object to be thawed (a frozen block of fish or meat) on a metallic thawing plate in an external vibration applying machine including an electromagnetic vibration generating part and the metallic thawing plate a step of mounting a metallic electrode on the frozen block of fish or meat, in which an electric power supply for electrification and the metallic electrode are included in a Joule heating machine and a step of providing external vibration with the frozen block of fish or meat together with electrifying the frozen block of fish or meat to subject the frozen block of fish or meat to Joule heating. An apparatus for thawing frozen fish, shellfish and meat comprises: an external vibration applying machine and a Joule heating machine, in which the external vibration applying machine includes: an electromagnetic vibration generating part and a metallic thawing plate, and the Joule heating machine includes: an electric power supply for electrification to generate Joule heat and a metallic electrode to be mounted on a frozen block of fish or meat.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】解凍時の細胞膜破壊がなく、旨み成分を含む水分(ドリップ)の流出を防ぎ、原体状態を極力維持し高品位の味が保たれ、解凍時間を短縮でき、病原菌の殺菌ができる、簡便な解凍方法及び装置を提供する。【解決手段】電磁振動発生部と金属製解凍板とからなる外部振動付与機の前記金属製解凍板上に被解凍対象(冷凍魚肉塊)を載置し、通電用電源と金属製電極とからなるジュール加熱機の前記金属製電極を冷凍魚肉塊の上部に載置し、冷凍魚肉塊に外部から振動を与え、同時に冷凍魚肉塊に通電してジュール加熱する冷凍魚貝肉類の解凍方法、及び外部振動付与機とジュール加熱機を有し、前記外部振動付与機が電磁式振動発生部と金属製解凍板とからなり、前記ジュール加熱機がジュール熱を発生させるための通電用電源と冷凍魚肉塊の上部に載置する金属製電極とからなる冷凍魚貝肉類の解凍装置。【選択図】図1
