This study on the longissimus lumborum(LL) of pig carcasses showed
that the use of blast chilling significantly reduced carcass temperature
and slowed down metabolic processes, accompanied by reductions in
the rate of pH decrease and the rate of EC rise during the initial periods
(at 2 and 6 h p.m.). At 24 h after slaughter, the chilling methods showed
no differences between ultimate pH, the range of their decrease, or final
EC.
