PROBLEM TO BE SOLVED: To provide a thawing sheet for frozen foods or a thawing method capable of thawing frozen foods of meats and fish in a short time with minimizing drip without affecting such frozen foods.SOLUTION: There is provided a heat absorption sheet having a material made by mixing a gelatinous body made by mixing a water-absorbing polymer and water or a viscous body made by mixing sodium carboxy methyl cellulose (CMC) and water with powder aluminum or powder ceramic encapsulated in a polymer or metallic bag having flexibility. There is provided a thawing method for thawing frozen sushi rice, sushi materials or sushi which are targeted frozen foods by folding the heat absorbing sheet in two and sandwiching the targeted frozen foods.COPYRIGHT: (C)2014,JPO&INPIT【課題】冷凍食品に影響を与えずドリップも最小限に抑え、短時間でこれら肉や魚等を解凍することができる冷凍食品用解凍シートや解凍方法を提供する。【解決手段】吸水性ポリマーと水を混合したゲル状体もしくはカルボキシメチルセルローズナトリウム(CMC)と水を混合した粘性体と、粉末アルミニウムもしくは粉末セラミックスとを混合した材料を高分子もしくは金属製の柔軟性ある袋に封入した、熱吸収シート。この熱吸収シートを2つ折りにして、解凍対象冷凍食品である冷凍寿司米あるいは寿司ネタもしくは寿司を上下にはさみ込み解凍する、解凍方法。【選択図】図1
