Summary

THE INFLUENCE OF GAS ATMOSPHERE PACKAGING (1) 15% CO2, 40% O2, 45% N2; (2) 60% CO2, 40% O2; (3) 10% CO2, 5% O2, 85% N2; (4) FILM OVERWRAP (CONTROL) ON THE MICROBIAL GROWTH AND SUCCESSION ON STEAKS WAS STUDIED DURING STORAGE. TREATMENT 3 WAS MOST EFFECTIVE IN REDUCING PSYCHROTROPHIC GROWTH ON STEAKS. PSEUDOMONAS SPECIES DOMINATED THE MICROFLORA FOR ALL PACKAGING TREATMENTS DURING EARLY STORAGE. IN ALL GAS ATMOSPHERES, SERRATIA LIQUEFACIENS INCREASED WITH STORAGE TIME AND THE 10% CO2 ATMOSPHERE SHOWED THE GREATEST INCREASE. ENTEROBACTER AEROGENES APPEARED LATE IN THE STORAGE PERIOD AND YERSINIA ENTEROCOLITICA WAS ISOLATED AFTER 12 DAYS FROM STEAKS IN ATMOSPHERE 1.
