Cereal Chem. 82(2):166-172 One commercial bread wheat flour with medium strength (11.3% protein content. 14% mb) was fractionated into starch, gluten, and water solubles by hand-washing. The starch fraction was separated further into large and small granules by repeated sedimentation. Large (10-40 pm diameter) and small (1-15 pm diameter) starch fractions were examined. Flour fractions were rec...
In this study, the cellulose crystals, prepared by acid hydrolysis of flax fiber, consisted of slender rods with lengths ranging from 100 to 500 nm and diameters ranging from 10 to 30 nm, respectively. After mixing the suspension of flax cellulose nanocrystals (FCNs) and plasticized starch (PS), the nanocomposite films were obtained by the casting method. The effects of FCNs loading on the morp...
The effects of heat treatment on oat and barley starch water dispersions were investigated. As compared with barley starch, the granules from oat starch were more degraded, but the fractionation patterns of both starches were not significantly different. Microscopic examination indicated that no evidence of amylopectin fragments was observed in the liquid fraction after starch dispersions were ...
background spinal anesthesia is an important and commonly used method for surgical anesthetic in operating rooms. however, even with identical drug dosage and administration mode, the extent of drug distribution in vivo is highly variable and difficult to control. preanesthetic administration of fluids immediately before spinal anesthesia (preload) is normal practice. the choice of fluid type m...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Influence of sulfur dioxide (SO2) and lactic acid (LA) on grain sorghum steeping efficiency in terms of wetmilling characteristics was investigated using response surface analysis. Tested ranges of concentrations in steeping water were 0.050 to 0.278% and 0 to 0.282% for SO2 and LA, respectively. Measured wet-milling variables were steeping solids yield, starch yield, protein yield, fiber/germ ...
The ruminal biohydrogenation of c9,c12-18:2 can be affected by the fibre/starch ratio of the diet and the ruminal pH. The objectives of this study were to examine independently in vitro the effects of fermentation substrate (hay vs. corn starch) and buffer pH (6 vs. 7) on the biohydrogenation of c9,c12-18:2 carried out by grape seed oil, focusing on its t11 and t10 pathways, using 6-h ruminal i...
Starch is of fundamental importance for plant development and reproduction and its optimized molecular assembly is potentially necessary for correct starch metabolism. Re-structuring of starch granules in-planta can therefore potentially affect plant metabolism. Modulation of granule micro-structure was achieved by decreasing starch branching and increasing starch-bound phosphate content in the...
In-line slit and capillary die viscometers were specially designed to study the viscoelastic behavior of plasticized wheat starch under lowhydrated conditions. A wide range of shear rates could be obtained by the use of different die geometries. The effects of temperature (110– 150 8C), glycerol (10–35%) and moisture contents (0–20%) were studied. The influence of the specific mechanical energy...
The claims of environmental protection and the lack of petroleum resources provide a new opportunity for developing plastic materials derived from biopolymer resources. Starch is one of the most studied and promising raw materials for the production of biodegradable plastics, because starch is quite cheap, abundant, biodegradable and edible. Starch consists of two major types of molecules, prim...
