マアジゲルの物性に及ぼす測定温度の影響 Effect of Measuring Temperature on the Physical Properties of Horse Mackerel Gels
In order to investigate the difference in the protein network structure among <i>suwari</i> gel, <i>kamaboko</i> gel, and <i>suwari-kamaboko</i> gel, the effect of measuring temperature on their visco-elasticity was examined. These gels were prepared from the same <i>surimi</i> paste of horse mackerel <i>Trachurus japonicus</i>, by setting at 40°C for 1h, by heating at 80°C for 30min, and by heating at 80°C for 30min after setting at 40°C for 1h, respectively. With rising the measuring temperature from 5°C to 40°C, storage modulus and loss modulus obtained by dynamic test, elasticity modulus and viscosity obtained by stress-relaxation test, and compression stress before breakage in a puncture test decreased for all the gels but the breaking force and breaking deformation increased. Furthermore, master curves could be drawn from the time-stress curves recorded by the puncture test for these gels. Based on the above results, the network structure in these gels and its dispersion in them were discussed.
