| Abstract: | ABSTRACT: The content of nucleotide metabolites in the muscle L.dorsi from 9 exudative and 9 acceptable quality pork carcasses was determined during 7 d of aging in order to establish a period postmortem for detecting exudative meats. Hypoxanthine and inosine levels in exudative meats were different (p < 0.05) from those of normal meats up to 3 days of aging, while 5'-inosine monophosphate (IMP) and 5'-adenosine triphosphate (ATP) contents only differed during the 1st 4 and 6 h postmortem, respectively. The IMP/ATP ratio was only different (p < 0.05) at 2 h. Thus, 2 h postmortem is proposed as the optimal sampling time for the detection of exudative pork meats. |
