The assessment effect of modified atmosphere packaging (60% CO2, 10% O2, 30% N2; MAP) and vacuum packaging on the quality of tilapia (Oreochromis niloticus) fillets stored at 4°C was investigated. Maximum inhibition of the bacteria mesophilic and psychrotrophic growth was achieved with stored under MAP. Moreover, tilapia kept under CO2-enriched atmosphere had lower total volatile base (TVB-N), ...
