The effect of high oxygen modified atmospheres on the quality degradation of packed live blue mussels (Mytilus edulis)

Oxygen (O2) plays a vital role in the blue mussel (Mytilus edulis) survival, microbial growth, and volatile organic compounds (VOCs) formation during transport storage. This study measures impact of different atmospheres (% CO2/O2/N2): 30/40/30; 40/60/0; 0/60/40 on mussels' spoilage. Quality parameters were monitored at 4 °C for up to 16 days storage, including headspace composition CO2/O2), pH, mortality, analysis, VOCs concentrations. Selected-ion flow-tube mass spectrometry (SIFT-MS) was used real-time measurements. At end odor activity values (OAVs) calculated assess that contributed overall profiles (OAV ≥1).
