To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...

Development of antibacterial and antibiofilm surfaces is in high demand. In this study, nanocomposite of Poly (ε-caprolactone)/Cloisite 30B was prepared by the solvent casting method. The membranes were characterised by SEM, AFM, and FTIR. Evaluation of water uptake, antimicrobial, antibiofilm, and microbial barrier properties demonstrated a significant antimicrobial and antibiofilm activity ag...

improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. in this work, titanium dioxide (tio2 )/low density poly ethylene (ldpe) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. the oxygen permeability of the nanocomposite with 4% of tio2 decreased for about 16% comp...

Functionalize nano-architecture CaO/Ag-chitosan bio-nanoparticles were prepared by the acetic acid sol-gel process and loaded into chitosan nanocomposite. The so bioactive nano-CaO/Ag-chitosan nanocomposite was characterized using XRD, TEM, FE-SEM, optical, antimicrobial activity evaluated. antibacterial evaluations implied that chitosan, nano-CaO, are exhibited subtle activities against both G...

Antimicrobial additives have been used successfully for many years as direct food additives. The literature provides evidence that some of these additives may be effective as indirect food additives incorporated into food packaging materials. Antimicrobial food packaging is directed toward the reduction of surface contamination of processed, prepared foods such as sliced meats and Frankfurter s...

Abstract There are several physical and chemical methods for synthesizing nanomaterials, while the most appropriate techniques involve using green chemistry eco-friendly material. Recently, synthesized materials different applications have gained attention as a result of their environmental friendliness cost-effectiveness. Applying nanoparticles (NPS) in food packaging has been extensively inve...

In this research work, the production of undoped and silver (Ag) doped zinc oxide (ZnO) thin films for food packaging applications was developed. The main goal was to determine the influence of coatings morphology and thickness on the antimicrobial performance of the produced samples. The ZnO based thin films were deposited on PET (Polyethylene terephthalate) by means of DC reactive magnetron s...

Bioactive essential oil components, aldehydes, terpenes and phenols can be encapsulated into nanosized emulsified droplets. Nano-encapsulated bioactive oils emulsions were prepared by high amplitude ultrasonic homogenization with food grade ingredients. The effect of delivery system on the antimicrobial activity of different oils components, e.g., carvacrol, lemon grass and cinnamaldehyde, was ...

Active food packaging involves the packaging of foods with materials that provide an enhanced functionality, such as antimicrobial, antioxidant or biocatalytic functions. This can be achieved through the incorporation of active compounds into the matrix of the commonly used packaging materials, or by the application of coatings with the corresponding functionality through surface modification. ...
