the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

Collagen was extracted from the skin of pigs, and blended with sodium alginate, starch, and sodium carboxymethyl cellulose. Food packaging films were obtained by crosslinking the blend with glutaraldehyde. Fourier transform infrared spectroscopy (FT-IR), SEM and TGA analyses were used to characterize the resulting films. A strong hydrogen bonding was detected between the composite film molecule...

In this study, the effects of growth temperature, starch composition and granule size on the gelatinisation and solubility properties of barley starch were studied. The mechanical properties and structures of amylose and amylopectin film, with and without added glycerol, were investigated. A novel starch-based microencapsulation method was developed for probiotic bacteria by combining native st...

The effect of orientation on the properties of amylose and starch films was studied in order to determine if film strength, flexibility, and water resistance could be improved. Potato amylose and high (70%) amylose corn starch were peracetylated, cast into films, stretched in hot glycerol 1-6 times the original length, and deacetylated. Molecular orientation of potato amylose films was much hig...

Edible films from chitosan, cassava starch, and gelatin plasticized with glycerol have been developed by casting method, and the effects of cassava starch (50, 100 and 150 g per 100 g of chitosan), gelatin (0, 25 and 50 g per 100 g of chitosan) and glycerol (21, 42 and 63 g per 100 g of chitosan) from the film solution on various properties of chitosan-based films have been studied using respon...

Water vapor diffusion coefficient (WVDC) and thermal diffusivity (alpha) were determined in gelatin-starch films through photothermal techniques. The effect of different variables in the elaboration of these films, such as starch and glycerol concentrations and pH, were evaluated through the response surface methodology. The results indicated that an increase in the glycerol concentration and p...

Abstract Background Cellulose extraction from gloss art paper (GAP) waste is a recycling strategy for the abundance of waste. Here, study was conducted on impact ultrasonic homogenization cellulose GAP to improve particle size, crystallinity, and thermal stability. Results At treatment temperature 75.8 °C, power level 70.3% 1.4 h duration, with properties 516.4 nm 71.5% stability 355.2 °C were ...

Edible film is a thin layer that used as substitute for synthetic plastic or primary packaging of food product. Corn starch suspended with chitosan and glycerol able to improve the quality edible film. The purpose this research determine physical characteristics from modified corn starch. concentrations were 15%, 20% 25%, 30% 40%. Physical observed thickness, absorption, solubility degradation....

kaolin-based film as surround wp® was applied to ‘galaxy’ apple trees to evaluate its effects on postharvest fruit quality. following harvest, the surround wp® on the fruit skin was either wiped off, or left unwiped, then, the fruits from these treatments along with fruits from non-surround wp®-treated trees as the control were stored at 6°c for 100 days. surround wp® film application reduced w...
