Severino et al. (2015) incorporated bergamot essential oil to nanoemulsions on modified chitosan edible films and coatings. Edible films were capable to inhibit E. coli O157:H7 and Salmonella Typhimurium when bergamot essential oil was incorporated to chitosan coatings applied to green beans, exhibiting a bactericidal effect against the two tested patho-gens during storage. They reported that in combination with other preservative treatments like γ-irradiation and modified atmosphere packaging the results were extremely effective against bacterial growth during storage, not only in controlling microbial growth, but also in reducing inoculated population.
