PURPOSE: To obtain a devil's tongue-like food excellent in viscoelasticity, heat resistance, salt resistance and palate feeling by heating and coagulating a dispersion containing a specified amount of curdlan under specified conditions to effect ready gelation.

CONSTITUTION: A dispersion containing 0.5-8wt.% of curdlan is brought to an alkaline state of ≥pH 10 to effect dissolution of the curdlan; an acid such as adlpic acid or citric acid is added to the resultant solution to neutralize the solution to pH 2-9, and 0.1-0.5wt.% of seaweed powder (e.g. Wakame seaweed, tangle, Hizikia fusiforme, green layer) is added to the solution followed by heating at 60-130°C and coagulating the solution, to obtain the objective devil's tongue-like food. It is preferable that the above seaweed powder-added solution be injected into a coagulating liquid at 40-100°C containing 0.05-10wt.% of a polyvalent metal salt such as calcium chloride to effect thready coagulation to obtain a thready devil's tongue-like food.
