Resumo
In this study, the effect of evaporated ethyl pyruvate (EP) was evaluated for the decontamination of Salmonella Enteritidis on chicken leg meat as a safe alternative to antimicrobial agent. Also, total aerobic mesophilic bacteria (TAMB), Enterobacteriaceae, Escherichia coli and yeast-mold counts samples were investigated. Subsequently, the samples were injected with 0, 42, 105 and 420 mg evaporated EP/L air to the paper filter attached to the container cover and stored at +4 °C for 10 days. According to the results, 42 mg EP/L concentration did not cause a significant decrease in Salmonella Enteritidis count (p>0.05). However, it was determined that 105 and 420 mg EP/L treatments reduced the number of Salmonella Enteritidis by more than 1 and 2 log, respectively. EP application also significantly influenced the number of TAMB, Enterobacteriaceae and yeast-mold. These results indicate that EP is an effective antimicrobial that could be used to enhance the safety of chicken meat.(AU)
