The pork-butt and beef-loin samples inoculated with E. coli
O157:H7, S. Typhimurium, and L. monocytogenes and the noninoculated
samples were treated with the thin-layer DBD plasma
for 0, 2.5, 5, 7.5, or 10 min. Each sample was placed inside the food
package containing the DBD-plasma system; the package was then
sealed using the zipper to confine the reactive chemical species
generated during plasma treatment. Immediately after DBDplasma
treatment, respective samples were used for microbial
analysis and instrumental color measurement. The other samples
were stored under commercial storage conditions at 4 C until the
next day for the analysis of other physicochemical properties and
sensory parameters.
