Ternary nano-biocomposite films based on poly(lactic acid) (PLA) with modified cellulose nanocrystals (s-CNC) and synthesized silver nanoparticles (Ag) have been prepared and characterized. The functionalization of the CNC surface with an acid phosphate ester of ethoxylated nonylphenol favoured its dispersion in the PLA matrix. The positive effects of the addition of cellulose and silver on the...

In the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. The effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. The results show that the effect of nanoparticles on composite ...

in view of the importance environmental pollution caused by plastic food packaging, in recent years there is a considerable interest in edible films and coating based on polysaccharides, proteins, lipids or combination of them. edible coatings also serve as carriers of food additives such as anti-browning and antimicrobials agents, colorants, flavor, nutrients and spices, so act as active packa...

Introduction Biomedical polyurethanes generally possess good biocompatibility and mechanical properties but, due to the low Tg and relatively high concentration of soft segments, are relatively permeable to air and water vapor. The ‘traditional’ approach to the permeability problem is to modify the chemistry of the copolymer, particularly that of the soft segment. For example, replacement of po...

Hydrosol is a side product of essential oil extraction from plants. In this study, the effect of various ratios (5-100 %v/v) of cinnamon hydrosol replacement in the formulation of edible gelatin films was investigated. Physical properties were evaluated and the antibacterial properties of gelatin films against Staphylococcus aureus, Staphylococcus saprophyticus and Staphyl...

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) ...

The active emulsified blend films based on gelatin-pectin (5% w/w) containing virgin olive oil (VOO) (0.1–0.3 g/g biopolymer) and grape seed (GSO) were prepared by casting method. GSO showed slightly more decreasing effect than VOO ultimate tensile strength (UTS) strain at break (SAB) of however; had reducing the water vapor permeability (WVP). scanning electron microscopy (SEM) images that inc...
