摘要

The objective of the current study was to evaluate the antimicrobial action of different concentrations of acetic (0.3% and 0.4%) or citric (1% and 1.4%) acids and their combinations (1% citric acid plus 0.4% acetic acid and 1.4% citric acid plus 0.3% acetic acid) againstSalmonellaTyphimurium,Escherichia coliO157:H7 andStaphylococcus aureusin tabbouleh salad stored at 21, 10 and 4 °C. Acetic acid was more inhibitory towardS.Typhimurium andE. coliO157:H7 than citric acid at 21 °C;S.Typhimurium andE. coliO157:H7 cells were not detected in tabbouleh treated with 0.4% acetic acid after 5 and 7 days, respectively. The combined effect of acetic and citric acid was synergistic againstS.Typhimurium, andE. coliO157:H7, but not againstS. aureus.The combinations of acetic and citric acids reducedS.Typhimurium, andE. coliO157:H7 to below the detection levels after 2 and 3 days at 21 °C, respectively. However, these treatments significantly reducedS. aureusnumbers compared to the control at tested temperatures by the end of storage. Acetic and citric acids have the potential to be used in tabbouleh salad to reduce the risk fromS.Typhimurium,E. coliO157:H7 andS. aureus.
