Résumé

The effectiveness of lemongrass (EOs), sodium diacetate (OAs) and natamycin, a natural antifungal produced during fermentation by the bacteriumStreptomyces natalensis, was assessed in situ against four pathogens (Escherichia coli, Listeria monocytogenes, Salmonella Typhimurium and Aspergillus niger). The antimicrobial formulation was encapsulated in an alginate matrix to protect its antimicrobial efficiency and then the bioactive coating was applied on broccoli floret as a food model during 14 days of storage at 4 °C. A combined treatment of coating and γ-irradiation was also done in order to evaluate the possible synergistic effect between treatments. The in situtests of combined treatments were carried out on coated floret by applying 0.4 or 0.8 kGy of γ-irradiation. Results showed a synergistic effect between coating and γ-irradiation to reduce the growth of E. coli, L. monocytogenes, S. Typhimurium, and A.niger during broccoli storage at 4 °C.
