Characterising flavour differences in Mandarin fish muscle under live prey and formulated feed diets using flavouromics and metabolomics.

ABSTRACT: Substituting formulated feed for trash fish in aquaculture has the potential to reduce farming costs and decrease dependence on natural resources. However, the impact of such feed substitution on muscle flavour remains unclear. This study is the first to utilise two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC × GC-TOF MS) and liquid chromatography-mass spectrometry (LC-MS) to analyse differences in muscle flavour between mandarin fish (Siniperca chuatsi) fed live prey and those fed formulated feed. The results identified 65 differential flavour compounds, with four key contributors: 2,3-butanedione, (E)-2-nonenal, furan, 2-pentyl-, and (E)-2-octenal. Metabolomic analysis revealed 139 differential metabolites, with significant upregulation of amin
