Effect of Cold Dormancy Combined with Film Packaging on Quality and Metabolism of Crassostrea gigas during Ecological Ice Temperature Keep Alive
To optimize the oyster circulation operation mode and investigate the effects of different pre-treatment methods on the vitality and quality of oysters during the anhydrous preservation period, the actual industrial transportation was simulated, the harvested Crassostrea gigas were transported by co...

To optimize the oyster circulation operation mode and investigate the effects of different pre-treatment methods on the vitality and quality of oysters during the anhydrous preservation period, the actual industrial transportation was simulated, the harvested Crassostrea gigas were transported by cold chain to the place of sale, after artificial seawater recovery and depuration, they were treated in bulk and low temperature induced dormancy with film wrapping respectively and then treated under ecological ice temperature (0 ℃) for waterless preservation. The survival rate, weight loss rate, total bacterial count and coliform and muscle quality of oyster were measured.
