The aim of this study was to investigate differences in modified atmosphere packaging (MAP) for the improvement of the shelf life of fresh meat products. Three different conditions for preserving fresh sausages were tested: MAPI (20% CO2, 70% O-2, and 10% N-2), MAP2 (40% CO2 and 60% O-2), and MAP3 (40% CO2, 30% O-2, and 30% N-2)- Samples from the MAP2 group had fewer spoilage bacteria, stable red color (no change of a* value), and good physical attributes (high water-holding capacity, little loss from cooking, and low shear force needed for cutting) compared with samples from other treatment groups. Thus, high concentrations Of CO2 (40%) and 02 (60%) resulted in a longer shelf life for fresh sausages.

Abstract
The aim of this study was to investigate differences in modified atmosphere packaging (MAP) for the improvement of the shelf life of fresh meat products. Three different conditions for preserving fresh sausages were tested: MAPI (20% CO2, 70% O-2, and 10% N-2), MAP2 (40% CO2 and 60% O-2), and MAP3 (40% CO2, 30% O-2, and 30% N-2)- Samples from the MAP2 group had fewer spoilage bacteria, stable red color (no change of a* value), and good physical attributes (high water-holding capacity, little loss from cooking, and low shear force needed for cutting) compared with samples from other treatment groups. Thus, high concentrations Of CO2 (40%) and 02 (60%) resulted in a longer shelf life for fresh sausages.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
