Lettuce leaves were inoculated to contain a predetermined initial level of E. coli, held overnight at 4C, and treated with the following sanitizers: 100 ppm sodium hypochlorite; 0.25% citric acid plus 0.50% ascorbic acid; bubbling ozone; and 1.5 ppm ozone. The combination of citric acid and ascorbic acid dip for 2 min resulted in the least microbial reduction. Dipping into 1.5 ppm ozonated water proved to be less effective than bubbling ozone for 2 min. Moreover, treatment with bubbling ozone was found to be as effective as sodium hypochlorite solution. It was observed that, for short exposure times (2-5 min), the temperature (4-20C) of the washing water did not have a significant effect on the activity of ozone in terms of E. coli inactivation. Prior incubation time and temperature of inoculated lettuce leaves were shown to have a significant effect on the efficacy of the sanitizing treatment. Scanning electron microscopy images were used to visualize the E. coli populations on lettuce.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/92665</dc:identifier> <dc:identifier>oai:zenodo.org:92665</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>JOURNAL OF FOOD SAFETY 30(2) 288-299</dc:source> <dc:title>EFFECT OF DIFFERENT SANITIZING METHODS AND INCUBATION TIME AND TEMPERATURE ON INACTIVATION OF ESCHERICHIA COLI ON LETTUCE</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
