Abstract:To evaluate the effect of heating rate on gelation properties of silver carp and grass carp surimi,the dynamic rheological properties,gelation temperature (tgel) and activation energy (Ea) of the surimi under different heating rates (1℃/min,5℃/min and 8℃/min) were investigated.Results showed that storage modulus G′ and loss modulus G″ of silver carp and grass carp surimi were higher,while loss angle tangent tanδ were lower in the 1℃/min group than that in the 5℃/min and 8℃/min groups.The gelation temperature increased,but gel activation energy decreased with heating rate increasing.Gelation temperature of silver carp surimi was lower than that of grass carp,but gel activation energy was higher than that of grass carp at the same heating rate.
