Notes:
The effectiveness of electrical stimulation of calf carcasses by two different waveforms, one with a pulse frequency of 14.3 pulse sec−1, the other with a pulse frequency of 40 pulse sec−1, was compared by measuring muscle pH and Warner Bratzler (WB) shear values. Different muscles, in particular the semimem branosus (SM) and the longissimus (LD), responded differently to the two waveforms. For the LD, the 14.3 pulse sec−1 waveform was superior in that muscles from calf sides stimulated with this waveform had lower pH values and lower WB shear values than muscles from sides stimulated with the 40 pulse sec−1 waveform while for the SM the latter waveform was superior. These differences were confirmed by taste panel tests. The findings indicate that, when assessing the effectiveness of a particular stimulation system, it would be unwise to study only one muscle.
