Treatment with lauric arginate ethyl ester and commercial bacteriophage, alone or in combination, inhibits Listeria monocytogenes in chicken breast tissue

摘要: The inhibitory effect of a commercial bacteriophage preparation (ListShield) on Listeria monocytogenes, alone or in combination with treatment lauric arginate ethyl ester (LAE), was studied using artificially inoculated fresh chicken breast tissue. A mixture three L. monocytogenes strains (ATCC 19113, ATCC 19115, and 13932) tissue at approximately 4.5 log CFU/g, followed by LAE (l00, 200, 400 mg/kg) and/or phages. Tissues samples were analyzed after 5 min, storage 4 °C for 1, 2, 3 days. Phage-treated showed reduction 0.81 treated both phage during the period 1.96 CFU/g cell density. evaluated parameters such as pH, surface color, 2-thiobarbituric acid-reactive substance (TBARS) content, sensory analysis. No significant difference observed TBARS quality control days post phages (400 mg/kg). Thus, can be very effective reducing load fillets, either treatment.
