| 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 11141m of thickness. Fish stored in MAP conditions and vacuum 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 CO25 02 and N2 were used for 8 treatments of MAP and vacuum packages. Mixed gases including 20-100% CO2, 35-80% N2 and 0aw5% 02 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, microbia..... | ||
