In this study, the authors also found the same incidence of partly
PSE and PSE meat in the half-carcasses chilled using both methods
(Table 3). Dark, firm and dry (DFD) meat was observed only in one blast
chilled half-carcass. In our previous study, the rapidly chilled carcasses
had a lower incidence of partly PSE and PSE meat, but higher incidence
of DFD meat compared to the conventionally chilled halfcarcasses
(RYBARCZYK et al., 2012). PARK et al. (2007) observed that
either cold water showering or rapid chilling reduced PSE meat by 22%
compared to a conventional chiller-based slow chilling regime.
In this study (Table 4) the meat of the Duroc boars offspring had very
high rates of sensory properties and low shear force, which is probably
related to the high level of intramuscular fat. In a study in six genetic
groups of porkers (GRZES et al., 2005), the best culinary properties
were observed for the meat derived from pigs of the Duroc breed. The
high palatability and juiciness assessment, especially of the Landrace
x Duroc breed, could have been associated with the increase in fat
content of its meat.
In this study the authors observed no significant differences in the
sensory properties and shear force of the LL muscle between the
chilling methods, contrary to our previous studies (RYBARCZYK et al.,
2012) where blast chilling resulted in lower tenderness and worse
flavour of meat compared to conventionally chilled carcasses
