Nowadays use of edible films and coatings is increasing due to their biodegradability properties. Fish gelatin obtained from fish skin wastes can be used as an appropriate protein compound for preparing the edible films. It can be also replaced pork gelatin. In this study, films were prepared from fish gelatin and phenolic compound caffeic in four levels of 0%, 1%, 3% and 5% at pH>10, temperatu...

Kefiran, which was isolated from kefir grains, used for the fabrication of cryogel-films in presence plasticizers, such as glycerol and sorbitol. Varying concentration ratios exopolysaccharide/plasticizer system were employed process cryogel-film formulation their effect on physical (film thickness, moisture content, solubility) mechanical (tensile strength elongation at break) properties films...

Biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. Thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish Myofibril protein. The film forming solution containing 1.5%, 2% and 2.5%(w/v) Myofibril protein isolate of 100ml solution and glycerol ...

a novel starch/poly (vinyl alcohol)/nano-titanium dioxide (st/pva/nano-tio2) biodegradable nanocomposite film was prepared by homogeneously dispersed tio2 nanoparticles in different ratios of starch/pva-based materials, via a solution casting method. glycerol was used as plasticizer. the mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...

The use of PLA and PLA-g-AA/starch as materials for the controlled release of encapsulated PSB was evaluated. The results showed that the bacterium degraded both the PLA and the PLA-g-AA/starch composite films, resulting in cell release. Severe disruption of the film structure occurred after incubation for 60-90 d. The PLA-g-AA/starch (20 wt.-%) films were more biodegradable than those made of ...

Using biodegradable films is increasingly growing since they contain natural materials. In this study, sago starch and carboxymethyl Cellulose (CMC) were used in film preparation. Sago starch films with 0, 5, 10, 15 and 20% CMC concentrations were prepared using solvent casting method. The mechanical properties were determined according to standards of American Society for Testing and Materials...

Materials based on biodegradable polyesters such as poly(butylene terephthalate) (PBT) 20 or poly(butylene terephthalate-co-poly(alkylene glycol) terephthalate) (PBTAT) have potential 21 application as pro-regenerative scaffolds for bone tissue engineering. Herein is reported the 22 preparation of films composed of PBT or PBTAT and an engineered spider silk protein, 23 (eADF4(C16)), that displa...
