Kuktaite, R. 2004. Protein Quality in Wheat: Changes in Protein Polymer Composition During Grain Development and Dough Processing. Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6778-0 The overall objective of the present studies was to increase the understanding about protein quality in wheat, i.e. to make it possible to improve the production of wheat with desired quality for different en...

Whole-grain bakery products and cereals are valuable sources of dietary fiber, vitamins, and trace elements. However, the presence of phytate, could decreases mineral bioavailability due to its chelating properties. In this study, the effect of fermentation and baking on the phytate content of different bakery products was measured by HPLC; the mineral availability in bakery products during pro...

The rheological properties of wheat dough directly influence the texture and appearance of bakery products, and the effect of wheat proteins on flour dough properties is a question attracting considerable interest. We present results that complement this ongoing theoretical scrutiny by empirically relating intrinsic grain properties to end-use flour characteristics. More specifically, we presen...

This experiment was conducted at Azad University experiment station to evaluate the effects of planting date and time of nitrogen application on yield and sugar content of sweet sorghum in 2003. Four planting dates (May 4, March 19, June 3 and June 18) and three stages of nitrogen application (3-5/8 leaf stage, boot stage and soft dough stage) were assigned to the main and subplots, respectivel...

A cost-effective, faster and efficient way of screening wheat samples suitable for tortilla production is needed. This research aimed to develop prediction models for tortilla quality (diameter, specific volume, color and texture parameters) using grain, flour and dough properties of 16 wheat flours. Another set of 18 samples was used to validate the models. The prediction models were developed...

This study was conducted to improve the knowledge of molecular processes involved in the interaction between Fusarium graminearum and emmer in the course of grain ripening. Emmer plants were artificially inoculated with a F. graminearum spore suspension at anthesis. In the course of grain ripening from milk ripe to plant death stage, grains at four phenological growth stages were collected for ...

The architecture of baked breads made of fresh dough and frozen dough was depicted by magnetic resonance imaging (MRI). Pieces of bread (16 mm cubic cakes) were soaked in organic solvents containing various concentrations of heavy metals (Cu, Co and Fe) and images of the grain structure of the breads were obtained. Of the organic solvents tested, acetone was preferable because of its single pea...

A field experiment was conducted with four wheat varieties Raj4134, HD2733, NW 1014 and K9006 for characterization of heat stress tolerance traits under heat stress condition. Heat stress was induced by delayed sowing of 35 days from normal date of sowing so that grain filling stage of wheat could experience severe heat stress. Data related to plant height, chlorophyll content, starch content a...

Investigations were conducted on the level of the overall proteolytic activity in flour fractions as well as fine and bruise bran, obtained from four varieties of wheat (‘Zyta’, ‘Pegassus’, ‘Sukces’, ‘Tonacja’), subjected to pre-harvest sprouting. Moreover, an analysis was conducted on the effect of pre-harvest sprouting on the functional properties of flour, determining the physical properties...

Multispectral remote sensing has potential to provide quick and inexpensive information on sugarcane aphid, Melanaphis sacchari (Zehntner), pest status in sorghum fields. We describe a study conducted to determine if injury caused by sugarcane aphid to sorghum plants in fields of grain sorghum could be detected using multispectral remote sensing from a fixed wing aircraft. A study was conducted...
