Özet
The natural polymer-based electrospun fibers and fibrous mats have sparked a lot of interest in both academic and industry, and they are being used in a wide range of applications including food packaging and coating due to their biocompatibility, edibility, hydrophilicity, and nontoxicity nature. Encapsulating medicinal and aromatic plant (MAP) extracts into biofibers is a viable method for obtaining desirable biofiber properties for edible food packaging (EFP) applications. Here, angelica root (Angelica sylvestris) oil (ARO) was encapsulated into a Zein/ Hyaluronic Acid/Gelatin based biofiber using an emulsion electrospinning process to fabricate EFP materials. First, volatile compounds in ARO were identified using GC/MS. It was found that fatty acid esters are the major compounds in ARO and; eucalyptol, iso-psoralen and thymol are other volatile compounds. The conductivity and viscosity of as-prepared emulsion were investigated. Then, morphology, and chemical properties of electrospun biofibers were studied using SEM and FT-IR, respectively. Then, their mechanical and antimicrobial character-istics were analyzed. Although the inhibition of ARO on bacteria differed according to the gram (G) charac-teristics of bacteria, inhibition of biofibers on bacteria was observed only when the amount of ARO in the biofiber was increased to 20%. Release kinetic models of eucalyptol and thymol, major essential oil components of an-gelica root oil, were also studied. Experimental data were fitted to different models, and it was found that thymol and eucalyptol release followed the Fickian, and non-Fickian models, respectively. Therefore, ARO loaded fibers have the potential to be an EFP material with their antimicrobial and mechanical properties.
