Conteúdo: 	The nanoencapsulation of essential oils for biodegradable films functionalization is a viable alternative for the production of active food packaging. In this study, the Cinnamodendron dinisii Schwanke essential oil was nanoencapsulated using zein as wall material, and applied in chitosan matrix to produce an active nanocomposite film packaging for food conservation. The chemical composition of the Cinnamodendron dinisii Schwanke essential oil showed a variety of unexplored bioactive compounds, and 1,8-cineole was the major compound. The oil nanoencapsulation produced stable and homogeneous nanoparticles with zeta potential close to 30&#8239;mV and polydispersity index lower than 0.2. The nanoparticles size showed a size variation between 70 and 110&#8239;nm. The chitosan films obtained functionalized with nanoparticles demonstrated antioxidant activity and antimicrobial activity. The active packaging containing zein nanoparticles was efficient in the conservation of ground beef, stabilizing the deterioration reactions and preserving the color.
