dc.description.abstractTHIS RESEARCH EVALUATED THE CONTRIBUTION OF NANOCOMPOSITE FILMS BASED ON DIFFERENT CONCENTRATIONS OF NZH-CU (1%, 2%, AND 3%) TO THE MICROBIOLOGICAL, ORGANOLEPTIC, AND PHYSICOCHEMICAL CHARACTERISTICS OF PACKED CHICKEN BREAST MEAT. ANALYSIS OF SOME MEAT QUALITY TRAITS, SUCH AS MICROBIOLOGICAL, CHEMICAL, AND PHYSICAL, WERE CONDUCTED ON A LABORATORY SCALE. FOR THIS, SMALL SQUARES OF CHICKEN BREAST MEAT, WEIGHING APPROXIMATELY 10 G, WERE ASEPTICALLY WRAPPED WITH RECTANGULAR PIECES OF 5 × 10 CM PLA-NZH-CU NANOCOMPOSITE FILMS, WHICH WERE STORED AT 4 °C FOR 20 DAYS. THE MICROBIOLOGICAL RESULTS INDICATED EFFICIENT ANTIBACTERIAL ACTIVITY (AT ANY NZH-CU CONCENTRATION IN THE NANOCOMPOSITE FILMS) ON THE TOTAL VIABLE COUNT OF GROUPS OF PSYCHROPHILES, AEROBIC MESOPHILES, ENTEROBACTERIACEAE, AND SALMONELLA SPP. UNTIL DAY 10 OF STORAGE (P < 0.05). NO SIGNIFICANT CHANGES WERE OBSERVED IN THE ORGANOLEPTIC (COLOR) AND PHYSICOCHEMICAL QUALITIES (TEXTURE, WEIGHT, PH, AND ACIDITY) UNTIL DAY 10 OF STORAGE AT 4 °C (P < 0.05). THE ANALYSIS OF THE EXPERIMENTAL TESTS CARRIED OUT DETERMINED THAT THE PLA-NZH-CU NANOCOMPOSITE FILMS PLAYED AN EFFECTIVE ROLE IN THE BACTERIAL SAFETY OF THE PACKAGED CHICKEN. IT WAS CONCLUDED THAT THE NZH-CU NANOCOMPOSITE FILMS, AT ALL CONCENTRATIONS TESTED, EXTENDED THE SHELF LIFE OF THE CHICKEN BREAST MEAT FOR UP TO 10 DAYS IN A REFRIGERATOR AT 4 °C.
