The aim of this study was to develop a novel ultrathin fibrous membrane with core-sheath structure as an antioxidant food packaging membrane. prepared by coaxial electrospinning, and the release active substances regulated its special structure. Ferulic acid (FA) incorporated into electrospun zein/polyethylene oxide fibers ensure their synergistic properties. We found that had good morphology smooth surface. internal stable, three materials we used were compatible. For different loading positions, it observed core layer ferulic-acid-loaded sustained action, while sheath pre-burst action. Finally, apples selected for using membranes simulate practical applications. effective in reducing water loss apple quality loss, well extending shelf life. According these experiments, FA-loaded zein/PEO electrospinning fiber can be will also undergo more improvements future.
