had lower mean TBARS values during the 10 days of storage compared to meat in O2 packages.
High O2 concentration led to higher lipid oxidation and modified atmosphere packaging did not extend the shelf-life of ostrich meats compared to air packaged ones. TBARS values of all air packaged ostrich samples remained lower than those of modified atmosphere packaged samples. This was observed during the entire storage time except in 60:40:0/O2:CO2:N2 atmosphere and 3:1 headspace packages, which showed at day 10 a difference to 8.78 mg MDA/kg (Fig. 3). Samples in 1:1 headspace ratios had higher (Pb0.01) TBARS values than those with a 3:1 headspace. These results agree with Ordonez and Ledward (1977) who stated that the concentration of oxygen in the atmosphere is the determining factor for the rate of lipid oxidation.
