In this study, we confirmed that S. Tennessee experienced
greater reduction than the other two Salmonella serovars which
indicates that S. Tennessee shows less heat resistance than the other
two serovars. There are some studies which correlate with the results
of the present study.reported that mean
D-values of S. Tennessee in aqueous sucrose of different aw were
smaller than those of S. Typhimurium.reported that D-values of S. Typhimurium and S. Senftenberg in
apple and orange juice were not significantly different.reported that D-values based on first-order kinetics of
three strains of S. Tennessee isolated from patients associated with a
2006e2007 peanut butter outbreak, 2 isolates of S. Tennessee from
sporadic cases unrelated to this outbreak, and 5 Salmonella strains of
other serotypes (S. Enteritidis, S. Typhimurium and S. Heidelberg)
were 13.4, 8.6 and 9.4 min at 90 C, respectively. In this study, we
reduced Salmonella by about 3e4 log after 5 min treatment with a
6 kW, 915 MHz microwave. Pasteurization of peanut butter by microwave
heating can dramatically reduce the processing time.
