Characterization of films of low density polyethylene incorporated with oregano essential oil

Abstract: The purpose of this study was to develop active films of low-density polyethylene incorporated with different concentrations of oregano essential oil (1, 2, 3, 4, 5 and 6% w / w). The production of the films was carried out in a modular mono screw extruder and the   antimicrobial activity was evaluated by the agar diffusion test. The films were analyzed for mechanical, optical and gaseous barrier properties to evaluate changes in the films due to the addition of an antimicrobial agent. As a result, it was foun… Show more

“…However, such preservatives exhibit a drawback, which is their volatile nature and consequent easy EOs loss from the packaging material. This fact motivated researchers’ efforts to develop different encapsulation technologies of EOs in food packaging materials and stabilizing their controlled release in food [ 11 , 12 , 13 , 14 ]. Valderrama Solano and de Rojas Gante [ 12 ] developed antimicrobial packaging materials by incorporating known concentrations ( w / w ) of oregano and thyme oil into LDPE via ionizing treatment and directly by extrusion.…”

“…2 promising inhibitory action against a broad range of food spoilage microorganisms. In the literature there is a plethora of studies with EOs addition on polymers such as polyethylene (PE), low density polyethylene [7][8][9], polyethylene tetraphthalate (PET) [10], polystyrene (PS) [11] and biopolymers such as starch, chitosan, gelatin, alginates, poly-lactide acid (PLA) active packaging films [12][13][14][15][16][17][18][19][20]. In addition, there are many studies with use of EOs active components in active packaging systems such as limonene, eugenol, thymol, cinnamaldehyde and carvacrol [21][22][23][24][25][26][27][28].…”
