Experiments were carried out with UHT-milk inoculated with Escherichia coli (E. coli), DH5? and Listeria innocua (L. innocua) WS 2258. Furthermore, the inactivation of microorganisms originally occurring in raw milk was investigated. E. coli, DH5? and L. innocua serving as biodosimeter were reduced by 4.58-log and 3.19-log, respectively. In milk, the original microorganisms showed a 4-log reduction. Without FGE the reduction was below 0.13-log. Thus, it can be derived that the efficacy of a UV-C thin-film reactor processing absorptive media like milk can be highly improved using FGE. © 2021 Elsevier B.V.en10.1016/j.ijfoodmicro.2021.109105info:eu-repo/semantics/closedAccessEscherichia coliListeria innocuaMilkThin film reactorUltravioletUV-Celementflow guiding elementpotassium iodidestainless steelunclassified drugabsorptionArticlebioprocesschemical analysischemical reactiondosimetryEscherichia coliheat treatmentinoculationListeria innocuanonhumanoptical densityraw milkultraviolet C radiationanimalbacterial countchemistrydevicesEscherichia colifood controlfood irradiationgrowth, development and agingListeriamicrobiologymicrofloramilkproceduresradiation responseultraviolet radiationAnimalsColony Count, MicrobialEscherichia coliFood IrradiationFood MicrobiologyListeriaMicrobiotaMilkUltraviolet RaysArticle343Q1WOS:0006332264000092-s2.0-8510132667033636589Q1
