Abstract: Docosahexaenoic acid (DHA) is a long chain polyunsaturated fatty of the omega‐3 series (ω‐3), which exerts strong positive influences on human health. The target this study was stabilization by encapsulation bioactive ingredient in zein ultrathin capsules produced electrospraying. DHA observed ATR‐FTIR spectroscopy to be more efficient against degradation under both ambient conditions and confined space (so‐called headspace experiment). In latter case, that closely simulates sealed...

In this context, chitosan is a sustainable, biocompatible, biodegradable, antimicrobial non‐toxic polysaccharide great relevance many fields application. Because its abundance nature excellent biocompatibility, cationic very promising polymer producing functional nanofibers. Although material has good physicochemical...

In this research, different contents of eugenol in the 2.5-25 wt.% range were first incorporated into ultrathin fibers poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) by electrospinning and then subjected to annealing obtain antimicrobial monolayers. The most optimal concentration PHBV monolayer was 15 since it showed high electrospinnability thermal stability also yielded highest bacterial reduction against Staphylococcus aureus (S. aureus) Escherichia coli (E. coli). This...

The main goal of this study was to develop poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films with long-term antimicrobial capacity interest in food packaging applications. To end, eugenol first highly efficiently encapsulated at 50 wt.-% the pores mesoporous silica nanoparticles by vapor adsorption. eugenol-containing were then loaded 2.5–20 range into PHBV electrospinning and resultant electrospun composite fibers annealed 155 °C produce continuous films. characterization showed...

This research work aims to study the influence of reprocessing cycles on mechanical, thermal, and thermomechanical properties polylactide (PLA). To this end, PLA was subjected as many six extrusion resultant pellets were shaped into pieces by injection molding. Mechanical characterization revealed that presented relatively similar up third cycle, whereas further induced an intense reduction in ductility toughness. The effect also studied changes melt fluidity, which showed a significant...

Novel active films of polylactide (PLA) containing extract Allium ursinum L. (AU), also called wild garlic, at 10 wt% were succesfully prepared by the electrospinning technology. Electrospinning AU-containing PLA solutions yielded fibers in 1–2 μm range with a beaded-like morphology, suggesting that AU was mainly encapsulated certain fiber regions. The resultant electrospun mats then subjected to annealing 135 °C obtain continuous application interest packaging. film cross-sections revealed...

In this research, the antibacterial and antioxidant properties of oregano essential oil (OEO), rosemary extract (RE), green tea (GTE) were evaluated. These active substances encapsulated into ultrathin fibers poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) derived from fruit waste using solution electrospinning, resultant electrospun mats annealed to produce continuous films. The incorporation resulted in PHBV films with a relatively high contact transparency, but it also induced...

Poly(3-hydroxybutyrate) (PHB) has gain in recent years a huge interest the food packaging field due to its renewable origin from waste as well non-food crops, high mechanical strength, medium-to-high barrier performance, and inherent biodegradability natural environments. Despite these advantages, PHB also shows narrow processing window brittleness since this homopolyester low thermal stability crystallinity, limiting industrial application. The present review provides an updated state of...

Collagen, as the major structural protein of extracellular matrix in animals, is a versatile biomaterial great interest various engineering applications. Electrospun nanofibers collagen are regarded very promising materials for tissue applications because they can reproduce morphology natural bone but have drawback poor consistency wet conditions. In this paper, comparative study between performance different cross-linking methods such milder enzymatic treatment procedure using...

Electrospinning of uniform biohybrid fibers with concealed cellulose microfibrils (CMF) is reported as a promising and environmentally sound concept for reinforcement polymer nonwoven fiber systems fine dimensions. The extraction refinement the high-strength crystalline microfibril bundles (15−20 nm thick) from bacterial networks presented, well their morphology prior to post electrospinning, Nanofibers composed poly(methyl methacrylate) (PMMA) matrix contents reaching 20 wt % were...

This work originally reports on the use of electrohydrodynamic processing (EHDP) to encapsulate Aloe vera (AV, barbadensis Miller) using both synthetic polymers, i.e., polyvinylpyrrolidone (PVP) and poly(vinyl alcohol) (PVOH), naturally occurring barley starch (BS), whey protein concentrate (WPC), maltodextrin. The AV leaf juice was used as water-based solvent for EHDP, resultant biopolymer solution properties were evaluated determine their effect process. Morphological analysis revealed...

This paper reports on the development and characterization of oxygen scavenging films made poly(3-hydroxybutyrate) (PHB) containing palladium nanoparticles (PdNPs) prepared by electrospinning followed annealing treatment at 160 °C.
