In order to clarify the rheological characteristics of the coagulated egg processed by ohmic heating, heating rate of liquid egg containing 0-2% salt was investigated under conditions of applied voltages ranged from 19 to 73 V and constant frequency of 60 Hz, and then the rheological behavior of coagulated egg was studied with stress relaxation tests in which the material was compressed to a constant strain. The average heating rate of liquid egg was directly proportional to the square of applied voltage, and it increased linearly with increasing salt content. The stress relaxation of coagulated egg consisted of three steps that could be expressed with a five-element Maxwell model. Analysis of the stress-relaxation of coagulated egg showed that the viscosity decreased, while the elasticity increased with increasing salt content in the range of 0-0.5%. However, there was no apparent effect of applied voltage on the viscoelasticity of coagulated egg.
