Phytochemicals and Antioxidant Activities

This work aimed to evaluate the antimicrobial effectiveness of a biodegradable composite, cellulose acetate film with the incorporation of various combinations of cinnamon, oregano and sweet fennel EOs against E. coli, S. aureus and Penicillium spp. Moreover, the mechanical and water vapor barrier properties of these films were evaluated. The films with the incorporation of pure oregano EO and the combination oregano + cinnamon EOs presented the best results. The water vapor transmission rate of the film was reduced with the addition of the EOs and the thickness of the film increased. The results suggest that the EOs incorporated as natural antimicrobial agents can potentially be used in food packaging, reducing the risk of microbial contamination of food.
