legumes are rich sources of protein and consider a good alternative to make a protein films. in this study, central composite design to investigate the simultaneously effect of the grasspea protein isolates (2 - 10 percent), glycerol (0.5 - 7%) and oleic acid (0 - 2%) on properties of edible films made from grasspea protein isolates, such as thickness, density, percentage of solubility in water...

background: development of biodegradable and biocompatible films based on protein polymer with strong antioxidant and antibacterial activities has gradually obtained extensive concern in the world. in this study, the improvement of gelatin film properties incorporated with ferula assa-foetida essential oil (fao) as a potential antioxidant/antibacterial wound dressing film was investigated. mate...

background and objectives: kefiran (kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. the expansion of mixed systems can propose kefiran and polyvinyl alcohol (pvoh) as a new composite film. materials and methods: solutions of 20 gra...

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...

in this study the feasibility of using salep as a new film-forming material was studied. the mechanical properties, water vapor permeability and thickness of salep films incorporated with glycerol were determined. increasing the content of dry material of salep from 1% to 3%(w/v) increased values for tensile strength and elongation at break from 16.16% and 18.85 mpa to 70.15% and 24.50 mpa resp...
