Linear viscoelasticity and microstructure of heat-induced crayfish protein isolate gels

Linear dynamic viscoelastic properties have been used to evaluate the influence of heat processing on the microstructure of crayfish protein isolate (CFPI) in order to explore the potentials of crayfish in the production of surimi-like gel products. CFPI dispersions have been subjected to a temperat...
