The aim of this research is to develop composite (CG-TA) films by using chitosan (CS)/gelatin (GL)/tannic acid (TA), for fresh-cut apples preservation. TA was used as the crossing-linking agent improve mechanical and barrier properties, active substance anti-ultraviolet antioxidant abilities chitosan/gelatin (CG) film. With incorporation from 0 1 wt%, tensile strength CG film increased while wa...

the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g...

Nowadays use of edible films and coatings is increasing due to their biodegradability and environment friendly properties. Fish gelatin obtained from fish skin wastage can be used as an appropriate protein compound for replacing pork gelatin to produce edible film. In this study films were prepared by combination of fish gelatin and different concentration (0%, 1%, 3%, and 5%) of two phenolic c...

Abstract This study was conducted to determine the effect of gelatin reology on mechanical, physical and morphological properties gelatin-based edible films. The aim this better understand variation viscosity structural behaviour films in presence glycerol sorbitol plasticizers. Gelatin-based were casted by using gelatins different viscosities as 2.5, 3.0 3.5 centipoise with plasticisers sorbit...

Tyrosinase (EC 1.14.18.1) a copper-containing monooxygenase, isolated from a fungal isolate Aspergillus niger PA2 was subjected for immobilization onto a composite consisting of chitosan and gelatin biopolymers. The homogeneity of the chitosan-gelatin biocomposite film was characterized by X-ray diffraction analyses. To evaluate immobilization efficiency, chitosan-gelatin-Tyr bio-composite film...

OBJECT Decompressive craniectomy plays an important role in the management of patients with traumatic brain injury (TBI) and stroke. Risks of decompressive craniectomy include those associated with cranioplasty, and may be related to adhesions that develop between the brain surface and overlying scalp and temporalis muscle. The authors report their institutional experience using a multilayered ...

Abstract Non-biodegradable petroleum-based packaging film waste has led to a severe environmental pollution and human health problems. Gelatin chitosan are attractive biopolymers for biomedical food applications due biocompatibility, biodegradability, renewability, nontoxicity, good gas barrier properties. However, disadvantages of the gelatin their low physicochemical stability poor mechanical...

Gold-gelatin bionanocomposite films are prepared by the reduction of gold ions by sodium borohydride in an aqueous solution. It is shown that both the solution and the films on glass substrates contain entrapped hydrogen micro- and nanobubbles with diameters in the range of 200 nm-3 μm. The optical properties of gold nanoparticles in the presence of gelatin and hydrogen nanobubbles are measured...

The objective of this research was to design a new colon‐targeted drug delivery system based on chitosan. The properties of the films were studied to obtain useful information about the possible applications of composite films. The composite films were used in a bilayer system to investigate their feasibility as coating materials. Tensile strength, swelling degree, solubility, biodegradation de...
