Rye flour based edible films were produced by using glycerol and ethylene glycol as plasticizers at concentrations ranging between 40 to 100% (w/w of rye flour). The structural, mechanical, physical, chemical properties the investigated. results showed that increasing plasticizer concentration resulted in a greater thickness, water vapor permeability, solubility films. While permeability not af...

  Objective(s): The aim of this study was to insert nitrofurazone in a chitosan membrane to be used as a wound dressing.   Materials and Methods: Several blend films using chitosan (Cs) and polyvinyl alcohol (PVA), containing nitrofurazone were prepared by means of casting/solvent evaporating technique. Different characteristics such as mechanical properties, water vapor transmission rate...

novel edible emulsified films were made using pistachio globulin protein (pgp) and palmitic fatty acid at concentrations of 2, 4, and 6 % w/w protein by tween-80 and homogenization technique. addition of palmitic acid to the pgp filmogenic solution resulted in great reduction of wvp in the emulsified films (37-40 %). concentration of palmitic acid did not create significant difference (p>0.05) ...

barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...

In this work, polyvinylchloride (PVC) membrane prepared via casting solution technique and phase inversion method. N, N dimethylacetamide (DMAC) was used as primary solvent and Tetrahydrofuran (THF) was used as a co-solvent. The effects of parameters such as membrane thickness, evaporation time of casting film before immersion precipitation and addition of polyethylenglchol (PEG) on PVC membran...

Hydroxypropyl methylcellulose (HPMC)–coated papers without plasticizer and plasticized with polyols were prepared, and the effects of coating weight, different plasticizers (glycerol (GLY), sorbitol (SOR), and polyethylene glycol (PEG)), and plasticizer contents (20% to 50%) on the physical and mechanical properties of the resulting biopolymer-coated papers were studied. Coating weight was the ...

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...
