Effects of pre-slaughter transport stress on the structure of pork MPs during postmortem aging, (A) CD spectra, (B) secondary structure ratio, (C) the amount of bound BPB, (D) intrinsic fluorescence spectra, and (E) particle size distribution spectra and average particle size. Different letters (A–C) indicate a significant difference among aging time points at the same treatment (p < 0.05); Different letters (a, b) indicate a significant difference between two treatments at the same aging time (p < 0.05). TR: three-hour transport followed by three-hour resting treatment; T: three-hour transport treatment.
