Abstract:
... The efficacy of ozone and ultraviolet light (UV) treatment as hurdles against Listeria monocytogenes suspended in fresh (9% NaCl, 91.86% transmittance) and spent brines (20.5% NaCl, 0.01% transmittance) was evaluated. Brines were inoculated with a cocktail of L. monocytogenes-strains N1-227, N3-031, and R2-499. Ozonation was performed by sparging gaseous ozone into brine. This was followed by UV i ...
