The linear viscoelasticity of the three grades of KAMABOKO, and its relation to ASHI, textural quality, were studied in non-resonant forced oscillation under 0.54-98.7 Hz and 12-60°C. The frequency and temperature dependences of shear storage modulus, loss modulus, and real part of the complex dynamic viscosity revealed that KAMABOKO was slightly crosslinked, and was a thermorheologically simple material. The temperature dependence of the shift factors of each grade of KAMABOKO did not conform to either the WLF equation or the Arrhenius one. No marked differences in the dynamic viscoelasticity at very small strain and in the tem-perature dependence of the shift factors could be found among the three grades of KAMABOKO. It is, however, probable that the difference in the quality of KAMABOKO may appear in the relaxation spectrum for the longer relaxation time region than that studied.
