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...

Melting of native tapioca starch granules in aqueous pastes upon heating is observed in situ using simultaneous small- and wide-angle X-ray scattering (SAXS/WAXS) and solution viscometry. Correlated structure and viscosity changes suggest closely associated amylose and amylopectin chains in the semicrystalline layers, and the release of amylose chains for enhanced solution viscosity occurs larg...

The study evaluated two novel coprocessed excipients (with two methods) as disintegrants in an orally disintegrating paracetamol tablet formulation. The tablets produced were assessed for mechanical properties with the use of friability and tensile strength while the release properties were assessed with wetting time, water absorption ratio, disintegration time and dissolution profile. The resu...

Since last five decades ago many natural, semisynthetic and synthetic compounds have been explored as excipients for pharmaceutical drug development. In all these compounds starches remain a strong choice because of its high availability, biocompatibility and multifunctional behaviour. Starches are one of the most used pharmaceutical excipient globally[1]. Although maize and potato starch is th...

This research aims to develop solid waste produced by oil palm plantation processing in the form of mesocarp fiber. Utilization which is usually only as boiler fuel a Palm Oil Mill. fiber reduce waste, has large heating value, and selling value. In process making briquettes, raw materials are provided, drying, charcoal (carbonization), filtering, forming 100 gr with 150 ml, 200 300 ml water sol...
