外文摘要：Differential metabolites and potential biomarkers of hybrid grouper and golden pompano muscles were identified in this study. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were performed to evaluate liquid chromatography-mass spectrometry (LC-MS) metabolomic analysis. Among the metabolites, 1678 co-contained differential metabolites in positive modes and 1445 co-contained differential metabolites in negative modes were investigated. Sixteen most differential metabolites were determined as potential biomarkers in different muscle groups. The top 10 KEGG-enriched pathways were identified. The sensory characteristics of groups were highest in aroma and sulfur-organic compounds in both fishes. Most organic acid contents in hybrid grouper were significantly higher than those of golden pompano. This present study provides a baseline for a better understanding of potential metabolites involved in muscle quality and taste as well as could provide a piece of further knowledge to identify the significant role of key biomarkers in fish muscles.
