Abstract:During the transportation of shellfish, due to the changes and stimulation of the external environment, it is easy to produce a stress response, leading to death or changes in flavor components, resulting in a decline in quality. Keep-alive transportation and quality maintenance are important methods to ensure the quality of shellfish products. In order to understand the current status of research and application of shellfish’s keep-alive circulation and quality control at home and abroad, this article systematically introduces the currently commonly used technologies and their Characteristics, quality changes and influencing factors in the process of keeping alive, quality maintenance methods and principles, analysis and discussion on solving the problems of shellfish in the process of keeping alive transportation, and corresponding solutions are put forward to keep the shellfish alive. And the development trend of quality control was prospected, aiming to provide theoretical basis and technical support for realizing the high-quality live circulation of shellfish.
