Some physical properties like Gas barrier, thermal stability, and mechanical properties and brittleness of pure biopolymers film are inadequate for food packaging. The functional properties of quince seed mucilage-based films were enhanced by addition of nanoclay (NC) (Cloisite 30B). Edible films were cast from heated aqueous solutions of quince seed (10% w/w) and NC (0.5%, 1%, 1.5%, and 2% w/w...

The non-biodegradable nature of plastic packaging has brought about an attention in bio-basedpackaging materials. Edible composite films were prepared using soy protein concentrate (SPC) and pullulan(PUL) biopolymer at five different ratio (100:0; 70:30; 50:50; 30:70 and 0:100) with glycerol as plasticizer bycasting-evaporation method. The thickness, mechanical properties, water vapor permeabil...

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...

Cold plasma is an innovative strategy to strengthen the polysaccharide-based films characteristics. This study evaluated effects of dielectric barrier discharge (DBD) on hydrophilic character, water vapor permeability (WVP), and tensile properties corn starch-based films. Starch were exposed processing operating at excitation frequency 200 Hz for 10, 15, 20 min. DBD resulted in further enhanced...

In this work, poly(lactide-co-trimethylene carbonate) and polylactide/ polytrimethylene carbonate films are prepared using a film blowing method. The process parameters, including temperature and screw speed, are studied, and the structures and properties of the P(LA-TMC) and PLA/PTMC films are investigated. The scanning electron microscope (SEM) images show that upon improving the content of T...

In the present paper, a series of totally novel bio-nanocomposite films from cellulose laurate (CL) and starch nanocrystals acetate (SNA) were fabricated, and the properties of nanocomposite films were investigated in detail. SNA was obtained by modifying starch nanocrystals (SNs) produced by sulfuric acid hydrolysis of corn starch with acetic anhydride. The favorable dispersity of SNA in chlor...

Chitosan films incorporated with various concentrations of gallic acid were prepared and investigated for antimicrobial, mechanical, physical and structural properties. Four bacterial strains that commonly contaminate food products were chosen as target bacteria to evaluate the antimicrobial activity of the prepared gallic acid-chitosan films. The incorporation of gallic acid significantly incr...

Utilization of hemicelluloses from biomass energy is an important approach to explore renewable resources. A convenient, quick, and inexpensive method for the preparation of blended films from quaternized hemicelluloses (QH) and carboxymethyl cellulose (CMC) was introduced into this study. QH and CMC solution were first mixed to form homogeneous suspension, and then were dried under vacuum to f...

Polymer blends of cold water soluble starches (amylose or amylopectin soluble starch) with gelatin were prepared using solvent casting method. The solid state miscibility and polymer-polymer interactions between the constituent polymers were studied by fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorirmetry (DSC), light optical microscopy (OP...

To valorize abundant, unexploited, and low-cost agro-industrial by-products, olive pomace is proposed as a sustainable renewable raw material for cellulose microfibers (CMFs) production. In this study, CMFs were extracted from using alkaline bleaching treatments characterized in terms of morphological, structural, thermal properties. Afterward, the reinforcing capability was examined carboxymet...
