2.2. Storage conditions
Ostrich meat was immediately sliced (eight steaks about
2.5 cm thick were cut from each muscle). Each pack (a total
of 60 packs) was prepared by placing two steaks (randomly
distributed) in a spanded polystyrene tray (318 · 235 ·
38 mm), which was overwrapped with a high barrier film
of water vapor permeability 1.1 g/m2/24 h at 23 C/50%
RH, nitrogen permeability 2.7 cm3/m2/24 h at 23 C/50%
RH, carbon dioxide permeability 23 cm3/m2/24 h at
23 C/50% RH and oxygen permeability <5 cm3/m2/24 h
at 23 C/50% RH (W.K. Thomas Spain S.L., Rubı´, Barcelona,
Spain). These packs were separated in 4 batches of 15
packs. Each batch was brought to different packaging
atmospheres using an EGARVAC packaging machine
(Barcelona, Spain). One batch was packaged directly by
sealing the film upon the tray (AIR). A second batch was
vacuum packed (VACUUM). The third batch was packed
in modified atmosphere using a gas mixture of 80%
