Effets du sexe et du muscle sur l’abondance de biomarqueurs de Tendreté et d’adiposité de la viande en aop maine anjou

Résumé

Some proteins have been revealed as biomarkers for beef tenderness and adiposity by previous studies. The abundance of these biomarkers could be affected by muscle, animal type (age, gender, breed) and the production system. This study analyzed the effects of animal and muscle type on the abundance of 20 biomarkers of meat tenderness and adiposity. The studied animals were 15 steers and 86 cows of the Maine Anjou PDO, and muscles were Longissimus thoracis, Rectus abdominis, Semimembranosus, Semitendinosus, Triceps brachii. The results showed that the abundance of the majority of tenderness or adiposity biomarkers varied significantly between muscles. Rectus abdominis is the most different from other muscles. Gender had an effect on the abundance of several biomarkers in four muscles. In Triceps brachii no effect of gender was observed. These results are valuable and should be considered when predicting meat tenderness and/or adiposity from the biomarker abundance and also when choosing the best predictor muscle.
