PROBLEM TO BE SOLVED: To provide a high-density blockish lyophilized food good in block shape and reconstitution tendency when to be eaten, and to provide a method for producing the same.SOLUTION: The blockish lyophilized food of such a type as to be eaten after being reconstituted into an aqueous edible liquid, is provided, which is produced by the following process: a cooked liquid adjusted so as to contain 9-90 mass%, on the whole solid basis, of di- to octa-saccharides 80°C or higher in glass transition temperature and contain 40-78 mass% of water is lyophilized to effect containing 9-90 mass%, on the whole solid basis, of the saccharides and being 0.23-0.72 g/cm3 in density.COPYRIGHT: (C)2012,JPO&INPIT【課題】ブロックの形状や喫食時における水戻り性が良好で、高密度のブロック状の凍結乾燥食品及びその製造方法を提供する。【解決手段】ガラス転移温度が80℃以上の2~8糖の糖類を全固形分中9~90質量%含有し、水分含有量が40~78質量%となるように調整された調理液を凍結乾燥して、ガラス転移温度が80℃以上の2~8糖の糖類を全固形分中9~90質量%含有し、密度が0.23g/cm3~0.72g/cm3である、水性可食液体に戻して喫食するタイプのブロック状の凍結乾燥食品を製造する。【選択図】なし
