A nanocellulose-gelatin (bacterial cellulose gelatin (BCG)) film was developed by a supplement of gelatin, at a concentration of 1%-10% w/v, in a coconut-water medium under the static cultivation of Acetobacter xylinum. The two polymers exhibited a certain degree of miscibility. The BCG film displayed dense and uniform homogeneous structures. The Fourier transform infrared spectroscopy (FTIR) r...

One of the mainly popular consumed colloid protein materials in pharmaceutics, medical, food and military industries is Gelatin. Especially from warm-water fish gelatin report poss similar characteristics to mammalian’s gelatin .Yellow fin tuna (Thunnus albacares) gelatin skin, lots of waste in form of skin and bones of the fish are produced every day. Analysis factors were extracted alkaline g...

Abstract Ariid catfish is a demersal fish species with high production rate. Fishbone by-product protein content converted into gelatin. Gelatin can be utilized as an edible film due to its low water resistance and tensile strength so that suitable polymer needed form good film, namely chitosan tapioca starch. This study aimed determine the effect of on characteristics best formulation ariid bo...

High pressure, at 250 and 400 MPa, for 10 or 20 min, was applied at either of two stages: during pre-treatment in acid at 10 8C to facilitate destabilisation of acid labile crosslinks, or during extraction in water at 45 8C to accelerate collagen hydrolysis. The resulting gelatins were evaluated in terms of yield of extraction, molecular weight distribution by SDS-PAGE, and viscoelastic propert...

The effects of glycerol and sorbitol as two plasticizers on mechanical properties, water vapor permeability, thermal properties, color and capability of heat sealing of gelatin films (of phytophagous fish, bovine gelatin with high gel-forming ability, and bovine gelatin with low gel-forming ability) containing clay nanoparticles were studied in this research. For this purpose, 6 × 2 × 3 factori...

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...

Thin films of were prepared by casting and its tensile properties like tensile strength (TS) and elongation at break (Eb%) were studied. The gelatin films were procured with two types of monomers such as 5% ethylene glycol (EG) and 5% ethylene glycol dimethacrylate (EGDMA) to increase the tensile properties. Five percent of monomer solutions were prepared in MeOH along with 2% photoinitiator; I...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

The physical and chemical properties of composite starch-based films containing cellulosic fiber, chitosan, and gelatin were investigated. Films containing both cellulosic fibers and chitosan demonstrated tremendous enhancements in film strength and gas permeation. The water absorbency of composite films could be greatly reduced in film composites containing cellulosic fibers and gelatin, but t...
