This article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (LDPE/starch) by infrared spectroscopy: Films of LDPE/Starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°C,and buried in the soil of public dump duri...

The properties and permeability of aroma compounds in food through the cassava starch films was investigated. Films were prepared by 5% starch and properties of the films were monitored at different concentration of two plasticizers; glycerol and sorbitol. Sorbitol-cassava starch films showed a better transmission rate (water vapor or/and oxygen), and had a higher mechanical properties; tensile...

The effects of konjac glucomannan (KGM) on thermal behavior of wheat starch have been studied in the presence of low concentrations of Na2CO3 (0.1-0.2 wt% of starch). Confocal laser scanning microscopy (CLSM) allows the visualization of the starch gelatinization process and granule remnants in starch pastes. Heating the starch dispersion in KGM-Na2CO3 solution significantly delays granule swell...

the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g...

A method to refine corn produces highly pure corn protein isolate (CPI) and intact granular starches (CPI starch). The CPI starch is superior to other commercial starches because of its intact membrane. This paper reports on the effectiveness of the CPI starch in laundering applications by comparison with a commercial starch and polyvinyl alcohol (PVA). Influence of the different starch materia...

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...

Starch- graft -poly(lactic acid) is put forward as an efficient compatibilizer of thermoplastic starch – PLA binary blend for a sustainable and high barrier film structures.

Starch-water slurries are commonly used to study fracture dynamics. Drying starch cakes benefit from being simple, economical, and reproducible systems, and have been used to model desiccation fracture in soils, thin-film fracture in paint, and columnar joints in lava. In this paper, the physical properties of starch-water mixtures are studied, and used to interpret and develop a multiphase tra...
