Abstract:
A tandem mass tag technology, based on the quantitative proteomics strategy, was applied to investigate the relationships between proteome changes of Penaeus vannamei (PNVN) muscles and quality characteristics during low-temperature storage. 506 proteins were found as differentially expressed proteins (DEPs) after 10 days of storage under treatments of refrigerated storage (5 °C), ice temperature storage (0 °C), and particle freezing storage (-3 °C) compared with a fresh group (0 day). In addition, Uniprot Knowledgebase (UniprotKB), Gene Ontology enrichment, and Kyoto Encyclopedia of Genes and Genomes were reported. Correlation analysis indicated that nine DEPs were significantly related to quality characteristics-pH, color, and texture. Bioinformatics analysis showed that most of DEPs were involved in binding proteins, metabolic enzyme, and protein turnover. Besides, several DEPs could be good candidate biomarkers of muscle decline. These results could help to further comprehend the proteome changes and mechanisms of the quality decline of PNVN muscles during low-temperature storage.
