The higher the concentrations of the antimicrobial solution, the better the antilisterial effects were. The treated inoculated beef samples were then stored at 4 °C for 30 days. During storage, Listeria growth inhibition effects were seen. While no growth was seen from the HAMS-treated samples, a 1.6 Log CFU/cm 2 increase was seen for MAMS-treated samples, a 4.6 Log CFU/cm 2 increase was seen for LAMS-treated samples, and a 5.7 LogCFU/cm 2 increase was seen for NoAMS-treated samples on Day30(~3Log CFU/cm 2 inoculation level).In the second stage,the impact of the roast beef storage time on solution's antilisterial effect was evaluated. Results showed
that the effect of the antimicrobial solution was dependent on both the initial inoculation levels and storage times.
