TENDERIZING CALLIPYGE LAMB WITH THE HYDRODYNE PROCESS AND ELECTRICAL-STIMULATION

The effectiveness of the Hydrodyne process and low voltage carcass ele ctrical stimulation (ES), either alone or in combination, for tenderiz ing muscle fr om callipyge and normal lambs was evaluated. One hundred grams of explosive was used for the Hydrodyne treatment Reductions in shear force with magnitudes of 33 to 67% were observed for the Hydrod yne treatment for the longissimus (LM) muscle from callipyge and norma l lambs, respectively. Carcass ES had no effect (P>0.05) on either cal lipyge or normal lamb shear values. However, ES improved the response (48%) of the Hydrodyne treatment in the LM of callipyge lamb. Shear fo rce for semitendinosus muscles averaged 3.53 kg and showed no response to either tenderizing treatment. Results suggest successful tenderiza tion of lamb LM with the Hydrodyne technology.
