摘要: The aim of this study is to identify the protein indicator of freshness of Coregonus peled using two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption ionization-time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF MS) methods. Samples were obtained prior to (control group) and 2, 4, 6, and 8 days after refrigerated storage for quality and proteomics analysis. Three proteins were found to have significant differential abundance in sample groups during the refrigerated storage, including l-lactate dehydrogenase, adenylate kinase isoenzyme 1, and myosin heavy chain, which were associated with freshness changes of C. peled. The freshness of C. peled fish during the refrigerated storage can be differentiated from the comparison of the specific proteins. Practical Application The changes of food quality pose not only the relative economical loses but also the potential implications on consumer's health. Proteomics can represent a powerful tool to explore potential biomarkers that may be related to meat quality defects. The identification of key protein biomarkers linked to freshness of Coregonus peled allows to monitor the response of the food matrix during storage and try to minimizes these defects.
