Special Issue Information

Dear Colleagues,

Aquatic products are favorable among consumers. However, large spoilage inevitably takes place during live transportation, storage and processing, which results in serious economic loss. This Special Issue encompasses the preservation techniques, transportation methods and establishment of a robust cold chain infrastructure. Researchers should explore advancements in refrigeration technology, packaging solutions and logistical strategies to mitigate spoilage, preserve freshness and extend shelf life. This Special Issue aims to delve into the challenges faced in different environments and regions, offering insights into best practices for industry stakeholders. Ultimately, the goal is to enhance efficiency, reduce waste and uphold product nutrition, meeting consumer demand for high-quality aquatic products while adhering to stringent safety standards.

Water-free transportation (WFT) causes shrimp (Penaeus vannamei) flesh quality deterioration. However, the roles of endogenous protease-induced protein hydrolysis have been neglected in the research. In the present study, calpain zymography, gelatinase zymography, the hematoxylin–eosin staining method, and other methods were applied to investigate the response of various endogenous proteases (cathepsin, calpain, and gelatinase), the myofibril fragmentation index (MFI), and the microscopic morphology of shrimp muscle during WFT in comparison with the shrimp under the conventional water transportation strategy (WT). The results showed that the total activity of proteases in shrimp muscle increased significantly (p ≤ 0.05) after simulated transportation. Cathepsins and gelatinases were activated during WFT. No significant (p > 0.05) changes of the activity of caspase-3 and the muscle cell apoptosis rate were detected in shrimp muscle cells after WFT. In addition, the MFI increased and the gap among muscle fiber bundles enlarged after WFT. Compared with WFT, no significant (p > 0.05) effect on the activities of calpain, gelatinase, and caspase-3 in the muscle of shrimp was found after WT, and only the activity of cathepsin L significantly increased (p ≤ 0.05). Based on the findings, we concluded that the activation of various endogenous proteases was induced during WFT. Full article
