PROBLEM TO BE SOLVED: To provide a thermally irreversible dry food which is suitable for eating and has good restorability. SOLUTION: This method for producing the thermally irreversible dry food comprises adding a starch compound and a coagulant to a material containing glucomannan as a main ingredient to produce the thermally irreversible gelled product, adding a saccharide to the gelled product, and then subjecting the mixture to a dehydration treatment for reducing the water content. For example, the method for producing the thermally irreversible dry food comprises (a) a process for mixing and swelling glucomannan with water and a starch compound, (b) a process for adding an alkaline coagulant to the swollen mixture and then continuously extruding the mixture into hot water, (c) a process for adding a saccharide to the thermally irreversible gelled product obtained in the process (b), and (d) a process for freezing and vacuum-drying the saccharide-added mixture. A raw material containing the glucomannan in an amount of≥50% or tuberous roots of devil's-tongue are used as a raw material. COPYRIGHT: (C)2006,JPO&NCIPI
