kaging systems reached values of above 98 and 95%,
respectively. After 7 d of refrigerated storage, the N2 concentration
inside the N2-enriched MAP decreased approximately 23%, while
this gas evolved within the Ar-enriched MAP (constituting 27% of
the headspace composition). In both MAP, the final content of CO2
and O2 were less than 16 and 9% for N2- and Ar-enriched MAP,
respectively. The final headspace gas composition of air-packaged
samples revealed comparable values of N2 (73%), while the
percentages of CO2 and O2 were approximately 15 and 12%,
respectively. The observed changes can be attributed to the plant
respiration and diffusion of gases through the LDPE film
