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 chillingmethods showed
no differences between ultimate pH, the range of their decrease, or final EC
