Escherichia Coli
Data on Escherichia coli described by researchers at University of Guelph
April 22nd, 2008
In this recent study, researchers in Guelph, Canada conducted a study "To evaluate the efficacy of ultraviolet (UV) light (254 nm) combined with hydrogen peroxide (H2O2) to inactivate bacteria on and within fresh produce. The produce was steep inoculated in bacterial cell suspension followed by vacuum infiltration." "The inoculated samples were sprayed with H2O2 under constant UV illumination. The log count reduction (LCR) of Salmonella on and within lettuce was dependent on the H2O2 concentration, temperature and treatment time with UV intensity being less significant. By using the optimized parameters (1.5% H2O2 at 50 degrees C, UV dose of 37.8 mJ cm(-2)), the surface...
