Cover Story (view full-size image): Natural extracts and essential oils were successfully encapsulated in ultrathin fibers of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) by electrospinning. The resultant electrospun mats were annealed to produce continuous layers and their antimicrobial and antioxidant activity was evaluated in both open and closed systems for up to 15 days. The electrospun PHBV layers containing oregano essential oil (OEO) showed the highest antimicrobial activity against two strains of food-borne bacteria as well as the most significant antioxidant performance, being therefore potential candidates to be applied as active layers in biopackaging structures to provide shelf life extension and food safety.
