UV-Heat Treatments for the Control of Foodborne Microbial Pathogens in Chicken Broth 2015 Access copy available to the general public Unrestricted This investigation established the process criteria for using UV-C light and mild heat (UV-H treatment) to inactivate 5-Log10 cycles (performance criterion) of common foodborne pathogen populations, Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus, when inoculated in chicken broth. To define the target microorganism and the proper UV-H treatment conditions (including UV dose, treatment time, and temperature) that would achieve the stated performance criterion, mathematical equations based on Geeraerd''s model were developed for each microorganism. For the sake of comparison, inactivation equations for heat treatments were also performed on the same chicken broth and for the same microorganisms. L. monocytogenes was the most UV-H resistant microorganism at all temperatures, requiring a UV dose between 6.10 J/mL (5.6 min) and 2.26 J/mL (2.09 min) to achieve 5-Log10 reductions. In comparison with UV treatments at room temperatures, the combination of UV and mild heat allowed both the UV dose and treatment time to be reduced by 30% and 63% at 55°C and 60°C, respectively. Compared to heat treatments, the UV-H process reduced the heating time for 5-Log10 reductions of all the investigated microorganisms in chicken broth from 20-fold to 2-fold when the operating temperature varied from 53 to 60°C. info:eu-repo/grantAgreement/ES/CICYT-FEDER/CIT-020000-2009-40 info:eu-repo/grantAgreement/ES/MINECO/AGL2012-33522 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.134 2015 MEDICINE, RESEARCH & EXPERIMENTAL 72 / 124 = 0.581 2015 Q3 T2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY 81 / 161 = 0.503 2015 Q3 T2 0.854 2015 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2015 Q2 Medicine (miscellaneous) 2015 Q2 Immunology and Microbiology (miscellaneous) 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-5895-2157 Gayán, E.
