In this study, we demonstrated that emulsion based nanoformulations sharing thefollowing composition 1%alginate/1.5%LEO/1%Tween 80 favors the inhibitory action oflemongrass (Cymbopogon nardus) essential oil against Rhyzopus spp., Penicillium expansumand Aspergillus niger, for at least 10 days of incubation. In addition to the positive preliminary in vitro results, future research is mainly needed to evaluate the in vivo antifungalactivity of the proposed systems.
