Summary

CONCENTRATION PROFILES OF PUTRESCINE, CADAVERINE, HISTAMINE, SPERMINE AND SPERMIDINE WERE DETERMINED IN MICROBIAL SPOILAGE OF FRESH PORK. STERILE MEAT SAMPLES WERE INOCULATED WITH SPOILAGE BACTERIA DOMINANT AT LOW TEMPERATURE. SPOILAGE INDUCED BY PSEUDOMONAS INCREASED THE PUTRESCINE CONCENTRATION ABOVE THE FACTOR OF 10 AND ENTEROBACTERIA THE CADAVERINE CONCENTRATION ABOVE THE FACTOR OF 100. CONCENTRATIONS OF HISTAMINE, SPERMINE AND SPERMIDINE DID NOT CHANGE CONSIDERABLY IN THE INITIAL STAGE OF SPOILAGE. NATURAL SPOILAGE WAS SIMULATED BY A MIXTURE OF THE TESTED STRAINS. THE BACTERIAL MIXTURE CAUSED A SIGNIFICANT INCREASE OF THE SUM OF PUTRESCINE AND CADAVERINE CONCENTRATIONS. THE CONCENTRATION INCREASE WAS WELL TO BE CORRELATED WITH THE SENSORY ASSESSMENT AND THE BACTERIAL COUNTS. IN BEEF THE BACTERIAL MIXTURE CAUSED A SOMEWHAT LOWER CONCENTRATION INCREASE.
