The Effect of Plasticizers on Mechanical Properties and Water Vapor Permeability of Gelatin-Based Edible Films Containing Clay Nanoparticles
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...

15 صفحه اولdetermination of some physical and mechanical properties red bean
چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولeffect of oleic and stearic acids on the mechanical, water vapor permeability and microstructural properties of sodium caseinate films
the effect of oleic and stearic acids on the water vapor permeability (wvp) and mechanical properties of sodium caseinate films was investigated. emulsifiers (span 80 and 85) were employed to produce the base mixture of film. tensile strength (ts), elongation (e) and young's modulus (ym) were obtained for both standard (without lipids) and hydrophobic films. results showed that the additio...
متن کاملthe effects of ribose on mechanical and physicochemical properties of cold water fish gelatin films
native fish gelatin has some disadvantages such as high hydrophilic, and solubility in cold water. mixing with other biopolymers and crosslinking by sugars may improve functional properties of fish gelatin. so in this research, the effects of ribose were investigated on moisture sorption isotherm, solubility in water, and mechanical properties of cold water fish gelatin (cwfg) films. ribose sug...
