Research on properties of collagen from silver carp scale.Rheological properties values and rheological curve of collagen solution were investigated by using MCR30 senior rheometer and NDJ-8S digital viscometer.The results showed that silver carp scale collagen solution as a typical pseudoplastic fluid.The viscosity of the collagen solution were significantly affected by shear rate,concentration and temperature.When the oscillation frequency was less than 20 rad/s,the silver carp scale collagen solution( 1.0%) mainly show in viscous behavior.When the oscillation frequency was greater than 20 rad/s,the silver carp scale collagen solution( 1.0%) mainly show in elastic behavior.After the occurrence of thermal denaturation of collagen,which is essentially the same fluid elastic behavior and viscous behavior decline.
