Summary

THE INFLUENCE OF POTASSIUM SORBATE CONCENTRATION (27-1325 PPM OF SORBIC ACID) ON THE GROWTH OF NATURAL FLORA IN RAW BEEF SAMPLES WRAPPED IN PLASTIC FILMS OF DIFFERENT OXYGEN PERMEABILITY WAS STUDIED AT 273 AND 277 K (0 AND 4 DEG C). CHANGES IN AEROBIC PLATE COUNTS, PSEUDOMONAS SPP, BROCHOTHRIX THERMOSPHACTA, LACTOBACILLUS SPP, ENTEROBACTERIACEAE AND YEASTS WERE MONITORED. SORBATE TREATMENT EFFECT ON PERCENTAGE INCREMENT OF LAG PHASE AND REDUCTION OF GROWTH RATE DURING EXPONENTIAL PHASE FOR THE DIFFERENT MICROORGANISMS WERE ANALYZED AND ANTIMICROBIAL ACTION WAS EVALUATED BY THE INHIBITIONINDEX.
