The Effect of Starch Microstructure on Glass Transition, Gelatinization, and the Elevation of the Gelatinization Temperature by Saccharides
The microstructure of starch and non-uniform distribution of water within starch granules affect how starch granules interact with water which in turn governs the magnitude, energy, and temperature of subsequent thermodynamic transitions.

Preparation and structure of Octenyl succinic anhydride modified waxy maize starch, microporous starch and maltodextrin
Octenyl succinic anhydride (OSA) modified starch is widely used in emulsion and encapsulation applications. The functionality of OS starch depends on its molecular structure. A systematic study was performed to investigate the reaction of OSA with granular waxy maize (WM) starch, microporous WM …

THE EFFECTS OF FEED PROCESSING ON THE FORMATION OF STARCH DAMAGE IN SOFT AND HARD WHEAT AND ITS IMPACT ON STARCH DIGESTIBILITY AND APPARENT METABOLIZABLE ENERGY IN BROILER CHICKENS
… for this is not known. It was hypothesized that starch damage is caused by hammer milling and pelleting but hard or durum wheat will have the highest levels due to hard endosperm structure and this increases starch utilization resulting in increased AMEn. The objective was to investigate the …

Probing the Ability of Flexible Hydrogels to Protect Fragile Objects
… or silica do not help. However, the addition of starch granules to the above gels greatly enhances their protective abilities. When a load strikes a gelatin gel with 20 wt% starch, the peak impact force is reduced by 25% when compared to a bare gel without the starch. Correspondingly, the …

Hydrocyclone fractionation of chickpea flour and measurement of physical and functional properties of flour and starch and protein fractions
Chickpea grain contains a high amount of starch and valuable protein. Many grain legumes (pulses) can be processed by pin milling and air classification with high separation efficiency. However, chickpea exhibits low separation efficiency because it has a relatively high fat content compared to …

An Ultrastructural Study of Fresh and Ensiled Alfalfa Using the Light and Transmission Electron Microscope
… xylem, and pith. Iodine staining (LM) showed starch localization in chlorenchyma cells. Transmission electron microscopy analysis showed starch localized in chloroplasts of chlorenchyma. Leaf cells averaged nine chloroplasts per cell section and eight starch granules per chloroplast section. …

Improving the quality of non-wheat bread made from maize using sourdough fermentation
… total maize flour) and pre-gelatinization of the starch in the maize flour with boiling water. The second was a Food and Agriculture Organization method which involved pre-gelatinization of the starch in 10% of the maize flour by cooking. The third method was a modern gluten-free sourdough method …

A Regulatory Role for 14-3-3 Proteins in the Starch Biosynthetic Pathway of Zea mays
Starch derived from cereal endosperm is responsible for supporting humanity’s global caloric requirements and is applied in various industrial applications. Semi-crystalline starch granules are comprised of glucose polymers, amylose and amylopectin, which are synthesized by four classes of enzymes …

Physicochemical properties and molecular structure of kiwifruit starch
… desirable nutritional properties. Kiwifruit is a starch-storing fruit: it accumulates abundant starch by the time commercial harvesting occurs, and most of the starch is gradually hydrolyzed into simple sugars during ripening. Starch plays an important role in kiwifruit development, but basic …

Granular Starch Hydrolysis for Fuel Ethanol Production
… of soft and hard endosperm. More exposed starch granules and rough surfaces produced from soft endosperm compared to hard endosperm will create more surface area which will benefit the solid phase hydrolysis as used in GSH process. In this study, the effects of protease, urea, endosperm …

White apple leafhopper affects apple fruit quality and leaf gas exchange
… These uninjured cells contained an abundance of starch granules, however, possibly indicating that they were not functioning properly. Spongy mesophyll cells dorsal to the feeding area were left intact as were the epidermal cells ventral to the feeding area. There was no evidence of cell wall …

Technologies for improving the quality of bread doughs made with barley spent grain and sorghum
… of protein bodies by the respective treatments. Starch granules observed by scanning electron microscopy (SEM) seemed to remain intact, indicating the effects to be protein-related. However, the elevated temperature (>50oC), glacial acetic acid treatment and combination thereof, reduced dough …

Identification of causal mutations of grain chalkiness in rice EMS populations via mapping-by-sequencing
… mutant has an opaque endosperm and abnormal starch granules and is inherited as a single locus recessive. Representative of the opaque/floury phenotype, grains of M3848 showed a higher grain percent chalkiness in comparison with that of IR64 Wild Type (IR64_WT). The contents of amylose in …

An Archaeobotanical Contribution to Foodways, Wood Collecting Strategies, and Niche Construction at the Late and Terminal Archaic Site of Côte Rouge in Southern Québec
… attested in the form of charred nutshells or starch granules on pebble tools. Finally, the potential for a local pollen analysis was judged poor but the observation of a selection of stone tools under high magnification revealed the presence of a few starch grains and brown and red residues …

Characterisation of the effect of stress on nitrogen metabolism in the commercially important agarophyte, Gracilaria gracilis
… of glutamine synthetase to intracellular starch granules. Overall, findings in the current study have suggested multiple roles for these metabolic enzymes that include nitrogen assimilation/transport, cell wall biosynthesis and senescence. This study led to the development of a model of …

Importance of zein composition in quality protein maize (QPM) to microstructural and chemical modifications of proteins during extrusion and their impact on texture of corn-based extrudates
… results of thermal and pasting properties for starch isolated from QPM and normal maize grits showed either no or negligible differences between starch of normal and QPM maize types. This finding allowed maize grits to be used in prospective studies for comparison of possible modifications in …

BioLaser: Establishing a High-Resolution Laser Ablation Tomography Platform for UK Bioimaging Research
… the automatic exposure and measurement of A-type starch granules in wheat seed endosperm, the high-resolution tomographic imaging of dried oat stems, and the successful tracking of vessels through green brachypodium node. This thesis lays the foundation for a high-resolution ultrafast laser …

Functional properties of white maize meal stored under tropical conditions
… were determined for maize meal and its isolated starches during storage of the white maize meal. The pasting properties in the cooking phase during storage of white maize meal were dependant upon humidity of storage. These observations were explained by hydrothermal effects due to prolonged …
