Peak force and total energy significantly decreased during the first 5 days of ageing in vacuum, but no difference was found between 5 (V5M0) and 15 days (V15M0)
Peak force and total energy for samples aged only in MAP (V0M5) or in a combination of vacuum
and MAP (V5M10) were not different from day 0 samples (V0M0).MAP steaks had higher thawing loss with increased ageing time, but there was no effect of ageing time in vacuum packaged steaks. MAP steaks had higher thawing loss compared with vacuum packed steaks at the same total ageing time of 5 days or 15 days. The steaks with the highest thawing loss were V5M10; however, some of that high thawing loss may be explained by the fact that V5M10 steaks were repackaged. For cooking loss, no clear difference between treatments was found (P=0.093). Total loss for steaks aged in MAP for 5 days did not differ significantly from vacuum packaged steaks stored for
15 days. Total loss was significantly higher for V5M10 than all other treatments.
