Anti-biofilm efficacy of single and binary treatments based on plant essential oils against Escherichia coli persistent in food-processing facilities.
Food Sci Technol Int. 2019 Jul; 25(5):385-393.FS

Abstract

The efficacy of single and combined treatments based on plant essential oils was investigated against Escherichia coli strains persistent in food-processing facilities. Surface materials (stainless steel and polystyrene), disinfectants (peracetic acid and sodium hypochlorite), and conditions (25 ℃, frequency of sanitizing of 24 h) commonly present in the food industry were also used to reach a more realistic approach. Thyme and pepper-rosmarin oils were significantly (P < 0.05) very effective against planktonic cells and biofilms formed by strains E6 and E7, respectively, followed by peracetic acid. Meanwhile, craveiro oil showed an efficacy that is significantly (P < 0.05) higher than sodium hypochlorite. All these disinfectants except sodium hypochlorite were able to kill 99.99% of biofilm cells in the range of concentrations tested (0.1%-3% v/v). However, binary treatments were needed to decrease the doses of these essential oils significantly (P < 0.05) for the control of E. coli biofilms. The effectiveness of peracetic acid against E. coli biofilms was also improved by blending with these essential oils. In particular, blends of pepper-rosmarin with thyme or peracetic acid demonstrated a suitable effectiveness for the control of persistent E. coli present in food-related environments. The application of these treatments could also reduce the current environmental impact generated during food-processing sanitization.
