Loins from non-fasted pigs and pigs fasted 12 h (either on
farm or at the abattoir) were mainly exudative but not pale,
and therefore were classified as RSE. Furthermore, a fasting
period up to 24–26 h did not modify the incidence of PSE
loins and did not increase the proportion of DFD pork, and
could be recommended to increase the percentage of RFN –
red, firm and non-exudative – and reduce RSE pork – red,
soft and exudative – which is one of the main technological
problems of the meat industry
