Edible films were made from proteins (corn-zein and wheat gluten) and celluloses (methyl cellulose and hydroxypropyl cellulose), and tested fog permeability of gases. Oxygen and carbon dioxide permeabilities of edible films were generally lower than those of plastic films. However, water vapor permeabilities of edible films were higher than those of plastic films. The concentration of plasticiz...

In this study, hemicellulose-based polymeric gel films were synthesized using the free radical polymerization mechanism. Hemicellulose was obtained from tea leaf brewing waste by delignification process. Polymeric produced in accordance with solution-casting technique. The effects of synthesis parameters investigated on structure and properties films. For purpose, characterized analytical test....

biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish myofibril protein. the film forming solution containing 1.5%, 2% and 2.5%(w/v)myofibril protein isolate of 100ml solution and glycerol a...

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...

The carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared by adding 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 was investigated. The best result was obtained through the nanocomposite film contain 3% nano...

Replacement of plastics used in the food industry seems to be a serious issue to overcome mainly the environmental problems in recent years. This study investigates the hydrophilicity and permeability properties of starch biopolymer which ethylene vinyl alcohol (EVOH) (0-10%) and nanocrystalline cellulose (NCC) (1-15%) were used to enhance its properties. Starch -EVOH nanocomposites were prepar...

The aim of this study was to evaluate a new packaging system in which the paper covered with solution sodium alginate and cinnamon essential oil (CEO) that used as for burger beef. papers were characterized their physical, optical, mechanical, sorption properties. In addition, burgers evaluated antioxidant activity, lipid oxidation, color difference. total, four treatments developed: Con: witho...

Whey protein coatings and cast films are promising for use as food packaging materials. Ongoing research is endeavoring to reduce their permeability. The intention of this study was to evaluate the effect of the reactive additives sodium sulfite, sodium dodecyl sulfate (SDS), and urea on the oxygen barrier, water vapor barrier, and protein solubility of whey protein cast films. The concentratio...
