Implication

Metabolomic analysis demonstrates heating duration alters fish muscle compounds across four species, indicating pyruvic acid serves as a universal thermal history marker.

Key Points

To assess the effects of heating duration on low-molecular-weight compound profiles across diverse fish species and identify species-independent markers of thermal history.
Subjected muscle samples from yellowtail, chum salmon, Alaska pollock, and Pacific herring to varying heating durations.
Performed gas chromatography-mass spectrometry (GC-MS) metabolic profiling, followed by compound annotation and semi-quantification.
Applied orthogonal partial least squares regression analysis to evaluate profile changes and identify candidate thermal markers.
Heating and extended heating durations significantly altered the low-molecular-weight compound profiles across all four fish species.
Pyruvic acid and glycolic acid were identified as candidate markers with high variable importance in projection scores, both increasing with heating duration.
Pyruvic acid demonstrated high correlation with heating duration across all species, with coefficients of determination R² ≥ 0.8.
