Abstract:

The changes in Ca2+-activate-factor (CAF) activity, myofibril fragmentation index (MFI) and shearing force value (SFV) of longissimus dorsi muscle (LDM) and psoas muscle (PM) from Duroc × Landrance × Yorkshire cross breed pigs were studied during storage at 0-4 ℃ for postmortem aging and correlation analysis among the three indexes was conducted. The results showed that all the three indexes had significant correlations with postmortem aging time, and there were significant correlations among the three indexes during postmortem aging, which indicate that both CAF and MFI are two significant indexes of pork tenderness as SFV.

Key words: pork, chilling aging, tenderness indexes, correlation
