The removal of foodborne pathogen biofilms with the treatment of ultrasound and/or organic acid

The purpose of this study is to investigate the effect ultrasound and/or organic acids against Escherichia coli and Listeria monocytogenes biofilms on microplates. In inactivation trials, pathogen formed microplates were exposed 2% acid (acetic, citric, malic lactic acid) for 10, 30 60 minutes. Biofilm detachment treatment with US was tested by microplate method based measuring optical density. study, removal foodborne varied depending (single or combined), time type (P<0.05). combined created additional biofilm detachment. min caused highest E. (77%) L. (70%) biofilms. Lactic among most effective both With increasing time, greater observed combination ensured safe more decontamination according single treatment. These findings indicate that can successfully be applied as an environmentally friendly technique in food industry.
