Relationship between adenosine 5′‐triphosphate (ATP) concentration and R‐value, defined as the absorption ratio of the degradation derivatives inosine 5′‐monophosphate (IMP), inosine and hypoxanthine (E 250 ) to adenosine nucleotides (E 260 ), was studied in postmortem lamb Longissimus dorsi, until onset of rigor mortis, at different temperatures of muscle storage and lamb carcass weight. Results showed a high overall correlation coefficient (r =−0.960), nondependent of storage temperature or carcass weight. Thus, lamb postmortem ATP concentrations can be indirectly calculated through a simple, rapid, economic and reliable method such as R‐value measurements.
