High-oxygen MAP negatively influences shear force, thawing loss
and α-tocopherol content, as well as the sensory attributes tenderness,
juiciness and flavour compared with beef steaks packaged only
in vacuum. The ageing time influenced the colour stability during the
following storage of steaks in air. Ageing in MAP induced higher levels
of MetMb compared with vacuum ageing during the following storage
of steaks in air. Steaks aged for 15 days in vacuum or 5 days in vacuum
followed by 10 days in MAP had lower colour stability than steaks
aged for shorter times.
