Post-mortem alterations (Glycolysis) of pantanal alligator's (Caiman crocodilus yacare) muscle

This paper presents a study of glycogen degradation in longissimus dorsi muscle of pantanal alligator. Glycogen concentration and muscle pH measurements were assessed. Glycolysis took about 50 hours to complete. Initial muscle pH value were in the limits of 6.6 and 6.7 and after 36 hours they dropped to 5.5-5.6. On the first 20-25 hours postmortem 80-85% of inicial glycogen was metabolized. Through histologycal PAS test it was observed during cold storage a decrease on the number of glycogen granules. On the first 20-25 hours postmortem 80-85% of inicial glycogen was metabolized.
