| Popis: | Salmonella Typhimurium is frequently isolated from chicken meat. The main purpose of current study was to analyze the decontamination of S. Typhimurium by using different concentrations of chitosan, lactic acid and chitosan and lactic acid combination on broiler carcasses. S. Typhimurium was inoculated to broiler carcasses at 108 cfu/mL in eight different study groups. Then, contaminated carcasses were treated with 1%, 2% lactic acid and 0.1%, 0.05% chitosan for 5, 10, 15 min. Also, effects of the combination of chitosan and lactic acid (0.05% chitosan- 1% lactic acid, 0.01% chitosan- 1% lactic acid) were analyzed for 5, 10, 15 min. Carcasses samples treated with chitosan and lactic acid were analysed for survival of S. Typhimurium on the 0, 3 and 7 days of storage time. Lactic acid (1%, 2%), combination of chitosan and lactic acid (0.05% chitosan + 1% lactic acid and 0.01% chitosan and 1% lactic acid) were detected to have antimicrobial effect on S. Typhimurium inoculated into carcasses (P0.05). According to the study, it was found that the combination of lactic acid and chitosan is the most effective method against S. Typhimurium in poultry carcasses. As a result, it is thought that the decontaminant agents which preferred in the study can be used in various applications in the poultry industry. |
