Resumen:
The biochemical bases of meat color are determined by the concentration and redox state of myoglobin, haemoglobin, cytochromes, and other pigments. Post mortem depletion of cellular oxygen results in oxidative stresses that consume NADH and affects reducing activity, while enzymatic detoxification influences the cellular oxidative processes, both affecting meat color. The aim of this work was to study the influence of several genes related to cellular oxidative processes that could affect CIELAB meat color parameters. The study was performed in steers that received a grass-based diet combined with different supplements (grains, hays and silages). A possible association of SNP with colorimetric parameters (a*, b* and chroma) in GSTP1 and LDHA genes was detected (P < 0.05). Although the influence of these enzymes on meat color has been suggested in previous studies performed at biochemical and protein expression level, further association studies in different populations and functional studies of proteins are needed to confirm these results.
