Increasing loin IMF by 1% improved predicted sensory TL ratings
by only 0.23 (Table 5) across the 1–6% range evaluated, representing
a relatively small influence of IMF on perception of tenderness
by panelists. At IMF levels of 1% and 6%, 50.7% and 57.4% of sensory
responses were predicted to be P7 on the 10-point scale, respectively.
One potential factor influencing the relationship between
IMF and TL in the present study is the 7–10 day aging period for
the fresh loin
