Proof of concept: predicting the onset of meat spoilage by an integrated oxygen sensor spot in MAP packages

During storage of modified atmosphere packaged (MAP) meat, the initial microbiota grows to high cell numbers, resulting in perceptible spoilage after exceeding a specific threshold level. This study analyses, whether elevated oxygen consumption headspace MA-packages would enable prediction method for meat spoilage. We monitored growth single spoiling species inoculated on high-oxygen MAP beef and poultry, performed sensorial analysis determined concentrations via non-invasive sensor spot technology. detected microbial occurring prior certain steaks. However, counts at onset were highly species-dependent, which resulted strong (Brochothrix thermosphacta) moderate (Leuconostoc gelidum subspecies) decrease content. No linear could be observed Carnobacterium divergens maltaromaticum poultry meat. demonstrate applicability an incorporated technology packages detection individual its onset. enables package evaluation sorting within retail, consequently reduces disposal as waste.
