Sažetak
Modied atmosphere packaging has been expanded and improved with the arrival of new technologies and increasing demands of
buyers. Modied atmosphere packaging is a mixture of dierent kinds of gases (Oxygen O2, Carbon Dioxide CO2 and Nitrogen N2)
in dierent ratios.
Total viable count of aerobic mesophyllic bacteria in fresh beef and pork meat packed in a modied atmosphere and unpacked meat
as control samples through the period of six days and stored at 4ºC, was determined in this paper. Total count of bacteria was lower in
meat packed in a modied atmosphere and was from 7 x 102 /g on the first day of beef meat storage, to 2.5 x 106/g on the sixth day
of storage. In control samples of beef, the total count was 8.8 x 104/g even on the rst day of storage; it was 4.2 x 106/g on the fourth
day, to be 1.6 x 107/g at the end of storage. The total count in pork samples packed in a modied atmosphere was from 1.8 x 103/g
to the most of 4.2 x 106 /g on the sixth day of storage. Unpacked pork contained 3.4 x 106/g even on the fourth day of refrigerator
storage, i.e. 8.8 x 107/g on the last day.
