The impact of electrospun films of poly(ε-caprolactone) filled with nanostructured zeolite and silica microparticles on in vitro histamine formation by Staphylococcus aureus and Salmonella Paratyphi A
Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Esen Alp-Erbay, Kelly J. Figueroa-Lopez, José M. Lagaron, Emre Çağlak, Sergio Torres-GinerAbstractThis research study originally reports the preparation and characterization of electrospun films based on poly(ε-caprolactone) (PCL) with high histamine-binding capacity. To this end, submicron PCL fibers filled with nanostructured zeolite or silica (SiO2) microparticles in the 5–20 wt% range were first prepared by solution electrospinning. The resultant electrospun composite fiber mats were thereafter thermally post-treated at 55...

Characterization and release kinetic of crosslinked chitosan film incorporated with α-tocopherol
Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Thanakorn Yeamsuksawat, Jun LiangAbstractThe aim of this work was to produce the in-situ crosslinking emulsification chitosan film by the casting solution method and to study the effect of sodium tripolyphosphate (TPP), sodium citrate (CT), and glutaraldehyde (GLU) for the physical properties, barrier properties, mechanical properties, and release kinetics of chitosan film incorporated with α-tocopherol. The release of α-tocopherol to the 50% ethanol was also studied and the diffusion coefficient calculated by the Fickian diffusion ...

Properties of active starch-based films incorporating a combination of Ag, ZnO and CuO nanoparticles for potential use in food packaging applications
Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Seyed Jamaleddin Peighambardoust, Seyed Hadi Peighambardoust, Niloufar Mohammadzadeh Pournasir, Parisa PakdelAbstractStarch (St)-based nanocomposite films containing single or a combination of Ag, ZnO and CuO nanoparticles (NPs) were prepared by the solution casting method. Physico-mechanical and antibacterial properties of the obtained films were investigated. The results indicated that St-ZnO film had higher tensile strength than those of St/Ag and St/CuO films at 2 wt.% of each NPs. Moreover, the film containing a combination of ...

A new nanocomposite based on LASiS-generated CuNPs as a preservation system for fruit salads
Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Maria Chiara Sportelli, Margherita Izzi, Annalisa Volpe, Valentina Lacivita, Maurizio Clemente, Cinzia Di Franco, Amalia Conte, Matteo Alessandro Del Nobile, Antonio Ancona, Nicola CioffiAbstractIn this work, nanocomposites based on polyethylene oxide (PEO) and copper nanoparticles (CuNPs) for food packaging application were developed as new active packaging for fresh foodstuffs. Copper colloids were synthesized by femtosecond-pulsed laser ablation synthesis in solution (LASiS) using an organic environment, to ensure a good solubility...

Antibacterial LDPE/GSE/Mel/ZnONP composite film-coated wrapping paper for convenience food packaging application
Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Shiv Shankar, Yeong-Ju Bang, Jong-Whan RhimAbstractLow-density polyethylene (LDPE) based nanocomposite film incorporated with grapefruit seed extract (GSE), melanin nanoparticle (Mel), and zinc oxide nanoparticles (ZnONP) was prepared by the extrusion-blowing method. The UV–vis spectra of LDPE/GSE/Mel/ ZnONP film exhibited the characteristic absorption peak of ZnONP at 370 nm. The UV-barrier, thickness, elongation at break, and thermal stability of LDPE film increased after the incorporation of GSE, Mel, and ZnONP, but transparenc...
