There has been a significant increase in the development of edible films and coatings recent times, this is expected to have impact on quality fruit vegetables coming years. Consumers expect fresh free from pesticide residues, with high quality, nutritional value an extended shelf life. The application fruits represents environmentally friendly approach innovative solution problem. Coatings can...

Starch-coated polyethylene (PE) films were prepared by immersing PE in a hot, jet cooked solution of starch. They were allowed to react with acrylonitrile (AN) in the presence of ceric ammonium nitrate initiator, and the graft polymerization that occurred produced starch-g-polyacrylonitrile (PAN) coatings that contained about 25 wt % grafted PAN. The starch-g-PAN coatings tightly adhered to the...

Assembly of carbon nanomaterials into two-dimensional (2D) coatings and films that harness their unique physiochemical properties may lead to high impact energy capture/storage, sensors, and biomedical applications. For potential biomedical applications, the suitability of current techniques such as chemical vapor deposition, spray and dip coating, and vacuum filtration, employed to fabricate m...

The rearrangement of the oil droplets in the film matrix during film drying, which defines its internal and surface structure, has an important role in the optical and mechanical properties of the emulsion-based films. The objective of this work was to study the effect of oil concentration and the use of surfactant sodium dodecyl sulfate (SDS) over color and mechanical properties of hydroxyprop...

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

A new approach is presented to produce amorphous porous silicon coatings (a-pSi) with closed porosity by magnetron sputtering of a silicon target. It is shown how the use of He as the process gas at moderated power (50-150 W RF) promotes the formation of closed nanometric pores during the growth of the silicon films. The use of oblique-angle deposition demonstrates the possibility of aligning a...

in this research, the effect of active edible coating based on carbocymethyl cellulose (cmc) containing pomegranate peel extract (ppe) and rese essential oil (reo) and also vacuum packaging (vp) on chemical attributes and microbial quality of packaged pomegranate arils during 15 days storage at 5 °c have been studied. the weight loss was increased by increasing storage time. but all treatments ...
