The texture of the material for imitation crab leg in foreign and domestic markets was psychorheologically investigated and approached from both sides of stress relaxation and creep measurements. The values of the relaxation modulus E(t) and the creep compliance J(t) were calculated from a system of plots between stress and strain with time t as a parameter. Then, continuous relaxation curves and continuous creep curves were drawn by the computer to give the best fit to the experimental points of E(t) and J(t). The connective equations between Maxwell model parameters of stress relaxation measurement and Voigt model parameters of creep measurement were derived from the differential equations. The Voigt rheological parameters were predicted from the stress relaxation data. Continuous creep curves were drawn using these predicted Voigt rheological parameters. For the most part, these curves fitted to the experimental points. Agreement was observed between the sensory evaluation and the stress relaxation/creep measurement, while reasonable relation was not observed between the sensory evaluation and the plunger penetration test. The measurement of E(t) was also effective to evaluate the physical property of the materials for imitation crab leg in both foreign and domestic markets. And E(t) and J(t) corresponded to the sensory softness even if the instrumental value of jelly strength did not correspond to the sense intensity of jelly strength.
