Abstract: 
The effects of modified atmosphere packaging (MAP) on the shelf life of Stellate sturgeon, Acipenser stellatus, fillets, (headed and gutted) stored in 4°C was examined and compared to vacuum condition. Three-layered packs (LDPE/EVOH/LDPE) were used with 110 mm of thickness. Fish stored in MAP conditions andvacuum samples (as controls), in different times, were evaluated for quality, chemical factors (TVN, PV and pH), microbial parameters (total viable count) and sensory factors. Different gases compositions of CO2, O2 and N2 were used for 8 treatments of MAP and vacuum packages. Mixed gases including 20-100% CO2, 35-80% N2 and 0-5% O2 were used for MAP conditions. Statistical analyses showed that quality, chemical, microbial and sensory factors were significantly different during cold storage (P<0.05) among treatments. Mixed gases showed no inhibitory effect on spoilage factors (chemical and microbial count), but the spoilage progress was delayed.
Increasing of the chemical, microbial and sensory changes in control samples were between 9 to 12 days but in MAP samples were 15 days, and in some such as "D pack" were even more. The "D pack" with mixed gases including "CO2 (60%) and N2(40%)" followed by the "G pack" including "CO2 (60%), N2 (35%) and O2 (5%)" were the best formula with a shelf life of at least 15 days. When CO2 concentration was increased, amounts of TVN and Microbial community were decreased in MAP packs and the shelflife was increased. The results also showed that storage of Stellate sturgeon fillets at -4oC in MAP condition prolongs storage time and increases the product shelf life even after 15 days.
