Abstract
Objective:
Meat is biochemically active, and the various pre-and post-harvest processes
can affect meat quality. Metabolomics is a valuable tool to elucidate metabolite changes in meat.
The overall goal of this study was to provide an overview of various techniques, data analysis, and
application of metabolomics in meat color research.
Results:
Both targeted and non-targeted approaches have been used to determine metabolite profiles in meat. Researchers use gas-, liquid-chromatography, and nuclear magnetic resonance platforms to separate molecules. Metabolomics is used to characterize muscle-specific differences in
color stability, meat tenderness, the impact of aging on meat color, and to determine metabolite profile differences between normal-pH and dark-cutting beef. Color stable muscles have more glycolytic metabolites than color labile muscles.
Conclusion:
The use of metabolomics has greatly enhanced our understanding of metabolites' role
in meat quality. There are challenges in data analysis; thus, there is a need for multiple platforms in
order to obtain comprehensive metabolite libraries specific to food. Metabolomics in combination
with wet-laboratory techniques can provide novel insights on the relationship between postmortem
metabolism and meat color.
