Starch is one of the most used polysaccharides in formulation Edible Films (EFs). This work aimed to develop starch-based EFs employing extrusion technology as a pretreatment casting technique and evaluate storage relative humidity (RH) effect determine their possible application food coating. Corn starch mixture plasticizers (sorbitol glycerol) were processed twin-screw extruder. The was for f...

background and objectives: preparation and evaluation of nanocomposite films have become prevalent in recent years. depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. the effects of montmorillonite (mmt), glycerol (gl), and thei...

pollution arising from plastic waste materials caused a great worry for researchers who are interested in protection of environment. this problem shifts their subject to bio-polymers for applications in packaging industries. however, their low water barrier properties are a critical problem. the effects of citric acid and methyl cellulose on water vapor and oxygen permeabilities and mechanical ...

the aim of this study was to investigate the rate of water vapor permeability (wvp) and moisture sorption of starch-montmorillonite (mmt) nanocomposite films. the nanocomposite films were prepared using the casting method andglycerol was used as a plasticizer. the effect of glycerol concentration on wvp of the films was determined at 25°c with a relative humidity of 0-99% (inside and outside of...

Potassium permanganate (KMnO4) is a dominant ethylene (C2H4)-scavenger extensively used in fresh horticultural commodities, mainly climacteric fruit, to prolong their shelf life. This material has been traditionally utilized as C2H4-permeable sachet for inclusion into packages of produces. New formulation strategies are required polymeric materials develop nanocomposites with scavenging potenti...

In the present work, faba bean protein (FBP) films plasticized with glycerol and reinforced different amounts (2.5, 5.0, 7.5 10% by weight of FBP) lignin extracted from pine cones (PL) have been obtained solution casting. The results showed an elongation at break 111.7% addition 5% PL to FBP film, which represents increase 107% compared control film. On other hand, it was observed thermogravime...

Films based on polysaccharides and proteins have been widely studied as possible substitutes for food packaging from fossil sources. However, its notorious sensitivity to water is still one of the primary drawbacks. In this study, sodium alginate (SA) hydrolyzed collagen (HC) blend films containing SiO 2 nanoparticles were prepared reduce sensitivity. The behavior these regarding vapor sorption...

Chitosan with sandalwood (Santalum album) essential oil (SEO) using malic acid as solvent were evaluated an active packaging film. It was applied sachet to butter packaging. The effects of SEO concentration (0.5 %, 1 % and 2 v/v) on chitosan film properties studied by measuring the equilibrium moisture content, solubility, water vapor permeability (WVP), mechanical, optical, heat sealability, a...

background: environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. the main objective of this study was to explore a calcium alginate based edible film to ...
