Implication

Experimental study demonstrates electrical stimulation accelerates glycolysis and rigor onset in lamb carcasses, indicating rapid freezing is possible without causing meat toughness.

Key Points

To determine how electrical stimulation affects post-mortem glycolysis, the onset of rigor mortis, and subsequent tenderness in lamb carcasses.
Delivered a brief series of 250 V electrical pulses to freshly slaughtered lamb carcasses.
Placed stimulated carcasses into a blast freezer at 5 hours post-mortem, compared against untreated controls held for 16 hours prior to freezing.
Evaluated the acceleration of post-mortem glycolysis relative to electrical pulse voltage.
Brief 250 V electrical stimulation accelerated the rate of post-mortem glycolysis and hastened the onset of rigor mortis in lamb carcasses.
Stimulated carcasses transferred to a blast freezer at 5 hours post-mortem exhibited equivalent tenderness to untreated carcasses held for 16 hours to prevent post-mortem shortening.
