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.

Опубликована: Май 1, 2024

Abstract The shapes of micro‐ and nano‐products have profound influences on their functional performances, which has not received sufficient attention during the past several decades. Electrohydrodynamic atomization (EHDA) techniques, mainly include electrospinning electrospraying, are facile in manipulate products' shapes. In this review, generated using EHDA for modifying drug release profiles reviewed. These linear nanofibers, round micro‐/nano‐particles, beads‐on‐a‐string hybrids. They can be further divided into different kinds sub‐shapes, explored providing desired pulsatile release, sustained biphasic delayed pH‐sensitive release. Additionally, resulted from organizations electrospun nanofibers discussed delivery, inner structures considered together developing novel delivery systems. future, related shape–performance relationships at nanoscale, besides size, structure structure–performance relationships, would play important roles promoting developments field.

Macromolecular Materials and Engineering, Год журнала: 2023, Номер 309(4)

Опубликована: Ноя. 23, 2023

Abstract In this study, three kinds of electrohydrodynamic atomization (EHDA) processes (electrospraying, electrospinning, and coaxial electrospinning) are implemented to create hydroxypropyl methylcellulose (HPMC) based ultra‐thin products for providing the fast dissolution a poorly water‐soluble drug ketoprofen (KET). An EHDA apparatus, characterized by novel spinneret, is homemade conducting processes. The types electrospun nanofibers E1, electrosprayed microparticles E2, core‐shell E3. SEM TEM results indicate that they have anticipated morphologies inner structures. X‐ray diffraction Fourier Transform Infrared verify KET mainly amorphous in all composites due its fine compatibility with HPMC. vitro tests demonstrate rapid release performances has an order E3>E1>E2≫KET powders. mechanisms suggested advantages compared. super performance E3 furnishing attributed synergistic action small size (of shell thickness), high porosity, state drug, solubility nanostructures can support development nano delivery systems (DDSs) through tailoring spatial distribution molecules within products.
