Characterization of Thermorheological Behavior of Alaska Pollock and Pacific Whiting Surimi
ABSTRACT: Thermorheological behavior of Alaska pollock (AP) and Pacific whiting (PW) surimi was evaluated during gelation at different moisture contents (80% to 95%). The temperature sweep data (storage modulus, G′, compared with temperature) for both surimi clearly indicated G’ minima. Unlike for t...
