Background: Edible films and coatings are biodegradable that can preserve the quality and extend the shelf life of foods. The aim of this study was to investigate the physical and mechanical properties, and antimicrobial activity of carboxymethyl cellulose (CMC) film containing Artemisia sieberi Essential Oil (AEO). Methods: The studied parameters were the antibacterial activity and physical p...

Nanofibers, produced through the novel method of electrospinning, have a high ratio surface area to volume, which allows them different optical, electrical, thermal, and mechanical properties than macroscale materials. In this study, it was aimed produce nanofibers with gelatin curcumin. The effects concentration crosslinking citric acid on characteristics electrospun were studied. Gelatin film...

Edible film dibuat dari pati sagu alami dan termodifikasi. Pati termodifikasi merupakan yang telah dipresipitasi (diendapkan) dengan pelarut etanol variasi waktu presipitasi (1, 2, 3, 4, 5 jam). Karakterisasi edible meliputi analisis gugus fungsi menggunakan FTIR, kadar air, kelarutan dalam sudut kontak, water vapor permeability (WVP), ketebalan, uji mekanik. Hasil menunjukkan bahwa proses modi...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

A novel nanopackaging film was synthesized by incorporating ZnO nanoparticles into a poly-lactic acid (PLA) matrix, and its effect on the quality of fresh-cut apple during the period of preservation was investigated at 4 ± 1 °C for 14 days. Six wt % cinnamaldehyde was added into the nano-blend film. Scanning electron microscope (SEM) analysis showed a rougher cross-section of the nano-blend fil...

in this study the feasibility of using salep as a new film-forming material was studied. the mechanical properties, water vapor permeability and thickness of salep films incorporated with glycerol were determined. increasing the content of dry material of salep from 1% to 3%(w/v) increased values for tensile strength and elongation at break from 16.16% and 18.85 mpa to 70.15% and 24.50 mpa resp...

introduction:packaging is an important factor in food industry and is dominated by petroleum-derived polymers. therefore, the amount of research involving the production and characterization of biodegradable films has increased substantially, mainly due to interest in minimizing the ecological impact caused by the use of synthetic packaging materials. several biopolymers have been exploited to ...

The antimicrobial, mechanical, physical and structural properties of chitosan-gallic acid films. Manuscript version of a work that was subsequently published in LWT – Food Science and Technology. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may ...

Background and Objectives: Kefiran (Kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...

Sustainable food packaging films were developed using a combination of k-Carrageenan (k-C), hydroxyl ethyl cellulose (HEC), silicon dioxide (SiO2), and silver (Ag) nanoparticles. The CH-SiO2/Ag nanocomposites showed promising results, mainly due to their transparency, flexibility, low cost, environmental friendliness. structure uniform morphology the determined by FT-IR, XRD, SEM analysis. Barr...
