Changes in the physicochemical properties of wheat, sago, tapioca and potato starches were studied after heating for 1 hour at 100oC, 110oC, and 120oC and for 2 hours at 120oC. These properties were characterised through the swelling behaviour of starch granules, amount of carbohydrate materials leached from the granules, starch paste retrogradation rate and gel strength. For all starches excep...

Graft polymerizations of vinyl acetate onto granular corn starch were initiated by cobalt-60 irradiation of starch-monomer-water mixtures. and ungrafted poly(vinyl acetate) was separated from the graft copolymer by benzene extraction. Conversions of monomer to polymer were quantitative at a radiation dose of 1.0 IvIrad. However, over half of the polymer was present as ungrafted poly(vinyl aceta...

Green banana flour was extruded through a co-rotating twin-screw extruder with constant barrel temperature. The objectives of this study were to determine the effect of extrusion cooking variables (feed moisture, FM, 20% and 50%; screw speed, SS, 200 and 400rpm) and storing of the extruded flours at 4°C for 24h on the physicochemical properties, resistant starch (RS), pasting properties and ant...

Starch is one of the most widespread and used biopolymers in different applications such as in the paper, textile, food, pharmaceutical and cosmetics industries (Richardson & Gorton, 2003). Even starch is useful in various industrial fields, its use as a native form has been restricted by some limitations (high viscosity, low solubility in cold water, paste instability, etc.) in specific applic...

the aim of this study was to design orally disintegrating tablets of olanzapine and to complex olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

Samples of blood and sera were obtained from unrelated adolescent and adult Bantus who were clinical patients at the Central Hospital. Males and females were pooled together for analysis. Hemolysates were analyzed by starch-gel electrophoresis methods using Tris-EDTA-borate buffer at pH 8.6 [1] and by cellulose-acetate electrophoresis in the same basic buffer system. Benzidine was used for stai...

Potato starch was extruded and roasted with apple distillery wastewater to produce esters substituted malic acid residues. The esterification degree higher at the roasting temperatures. Starch modification contributed its darker color, increased resistance action of amylolytic enzymes, decreased solubility heat phase transition. changes in other properties examined depended on extrusion process...

Abstract Edible film as food packaging is an alternative solution to maintain Dodol quality and prevent decay during storage. Commonly, edible films were prepared from starch-based materials. Nevertheless, the which only made starch has a limitation due does not provided antibacterial properties. Therefore, this study aims synthesis characterize of Nagara sweet potato with addition garlic essen...
