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....

As a biodegradable and flexible copolymer, poly(butyleneadipate-co-terephthalate) (PBAT) is used for packaging. However, high cost limited properties restrict its applications. Because of the hydrophobic nature PBAT, low mechanical are observed when PBAT cellulosic fibers, which hydrophilic, in blends. To increase interfacial adhesion between cellulose γ-(2,3-epoxypropoxy) propytrimethoxysilane...

The objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51SU. The four antigen preparations for immunization ofBALB/c mice were: CL: BLV-FLK cell lysate, UF: a fraction of CL (between 30 and 100 kDa), WVP: wholevirus particles and SP: with ion exchange chromatography, gp51SU was semipurified. A total of ninesucce...

The main aim of the present study was to investigate effect microwave irradiation time on photocatalytic and physiological comfort characteristics zinc-oxide-nanorod-coated cotton fabrics. An ultra-fast technique employed grow zinc oxide nanorods fabrics using a microwave-assisted hydrothermal method. axial (length) lateral (diameter) growth observed increase with time. ZnO uniformly entirely c...

Cold plasma (CP) is an effective strategy to alter the limitations of biopolymer materials for food packaging applications. Biopolymers such as polysaccharides and proteins are known be sustainable with excellent film-forming properties. Bio-based films can used alternative traditional plastic packaging. There hydrophobicity, poor barrier, thermos-mechanical For this reason, biopolymers must mo...

Abstract The current study was performed to develop biodegradable films with matrix composed from gum Arabic (GA) and different concentrations Alpinia officinarum phenolic extract (AOE). color indices, physical properties, surface shape, crystallinity, mechanical properties thermal stability of produced were investigated. incorporation AOE (0.25 g/100 mL) inside GA increased dark yellow color, ...

Preserved eggs are prone to lose water during storage, which causes the preserved shrink and have poor taste, bad flavor, reduced quality. By studying a degradable coating agent applying it eggs, we explored its effect on quality of storage. In this paper, structure performance gelatin film (GF), gelatin–bacterial cellulose (GBF), cellulose–MgO nanocomposite (GBMF) were by adding bacterial (BC)...

the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...
