This study investigated the changes in peptide and metabolite profiles in exudates from pork stored at different temperatures. The results suggest that these changes can be used as markers of pork spoilage.
Previous studies have evaluated pork quality by omics methods. However, proteomics coupled with metabolomics to investigate pork freshness by using pork exudates has not been reported. This study determined the changes in the profiles of peptides and metabolites in exudates from pork stored at different temperatures (25, 10, 4, and -2 degrees C). Multivariate statistical analysis revealed similar changes in profiles in exudates collected from pork stored at -2 and 4 degrees C, and additional changes following storage at higher temperatures. We identified peptides from 7 proteins and 30 metabolites differing in abundance between fresh and spoiled pork. Significant correlations between pork quality and most of the peptides from these 7 proteins and 30 metabolites were found. The present study provides insight into changes in the peptide and metabolite profiles of exudates from pork during storage at different temperatures, and our analysis suggests that such changes can be used as markers of pork spoilage.
