This study concerned the search for protein biomarkers of tenderness and adiposity in order to ensure maximum tenderness and optimum deposition of adipose tissue for a good expression of the organoleptic qualities of meat from Maine Anjou AOP. Two groups from a total of 111 cows were formed for extreme tenderness or lipid content and were compared by two-dimensional electrophoresis. The proteins differing between the groups were identified by mass spectrometry. This provides a list of biomarkers that are currently being evaluated on new samples in order to confirm their use in a final tool for the routine evaluation of tenderness and adiposity on carcasses or on live animals.
