Inhibitory potential of Eugenia sulcata essential oil and its nanoemulsions against Aspergillus spp.

Natural products are in the spotlight of novelty for obtaining ecofriendly agents against pests. In this context, searching for new antifungal alternatives for control of grain microorganism is recommended. In this paper we show a brief description of nanoemulsification as a valuable tool for modification of essential oil properties. Low energy method was used for the preparation of Eugenia sulcata nanoemulsion. This approach was also used for the preparation of this type of colloid with β-caryophyllene, the main component of this essential oil. Especially regarding Aspegillus parasiticus, it was possible to observe increment of bioactivity by nanoemulsification of E. sulcata. This short communication contributes to better knowledge of mechanism in the rationalization of antifungal nanoemulsions based in essential oil and its main constituents, providing relevant insights that can be used for other complex volatile mixtures.
