Proteomic biomarkers of meat colour of blonde d’aquitaine young bulls: towards a better comprehension of the biological mechanisms
Résumé
Relationships with CIE-L*a*b* colour traits of protein biomarkers known to be related to tenderness were studied in Longissimus thoracis muscles from 21 French Blonde Aquitaine young bulls. L*, a* and b* coordinates were correlated with 9, 5 and 8 of the 21 biomarkers, respectively. Regression models explained between 47 and 65% of the variability between individuals in L*a*b* values. Results suggest that development of colour and tenderness may share common biological pathways. They further show that inducible Hsp70s and μ-calpaïn influence the three colour parameters interactively.
