alpha-amylase activity of wheat flour is one of the important factors to determine its suitability for baguette bread making. in this study, setareh flour (81% extraction rate) was procured from six flourmills situated in six climatically different provinces. ph, moisture, ash, wet gluten and alpha-amylase activity tests were applied on flour samples and showed that the alpha-amylase activity i...

The object of this study was to determine whether oat, buckwheat and whole brown rice flours have a prebiotic effect on Lactobacillus casei, acidophilus (LA5), Bifidobacterium animalis subsp lactis (Bifidobacterium BB-12). In the study, skimmed milk inoculated with above-mentioned bacteria fortified flours. According results, oat stimulated all investigated, whereas flour had no for L. casei.

Endogenous factors responsible for the textural characteristics of buckwheat products were studied. An analysis with various buckwheat samples showed that there were variations in protein, starch, amylose and amylopectin contents among the various buckwheat flours examined. The protein contents of the buckwheat flours were significantly negatively-correlated to the starch, amylose and amylopect...

The physical and functional properties of trifoliate yam flours processed using different pre-treated methods at varying harvesting periods were examined. The flours were subjected to physical (bulk density) and functional (water absorption, solubility and swelling power) analyses. The bulk density values for the trifoliate flours ranged from 0.54-1.03 g/cm3. The parboiled flours had higher bul...

This study describes the application of the laser photoacoustic spectroscopy (PAS) for quantification of total carotenoids (TC) in corn flours and sweetpotato flours. Overall, thirty-three different corn flours and nine sweetpotato flours were investigated. All PAS measurements were performed at room temperature using 488-nm argon laser radiation for excitation and mechanical modulation of 9 an...

This research aims to vary functional properties of native and extruded wheat flours combining cyclodextrin glucanotransferase and extrusion treatments. The level of released cyclodextrins (CD) was assessed, besides the microstructure, crystallinity, pasting properties and starch hydrolysis of the flours. Photomicrographs of enzymatically treated flours suggested the production of fragile struc...

Soybean flours stored for 20 years at -20 degrees C retained protein polypeptide profile integrity. Proteins in stored soybean flours retained their immunoreactivity. Long-term frozen storage of seed flours at -20 degrees C did not adversely affect seed protein in vitro pepsin digestibility.

Two types of crushing were applied to grains of red sorghum: manual crushing using a mortar and pestle of kitchen and mechanical crushing using a hammer mill. The flours obtained at the end of these various crushing were filtered and subdivided in different fractions according to the diameters of the mesh of the sieves (0.16mm; 0.25mm; 0.315mm; 0.4mm, and 0.63mm...). Some physical, chemical and...

Whole flours from four oat lines with different amounts of beta-glucan (4.8-8.1%) were examined for their antioxidant activity and total phenolic and lignin concentrations. These data, along with the beta-glucan percentages, were compared with bile acid (BA) binding. Only the lignin concentrations of the flours significantly (P < 0.01) correlated with the BA binding values. The oat flours also ...

The nutrient composition, antinutritional factors and flour functionality of cowpea and horse gram flours were evaluated in comparison to chickpea flour characteristics. Protein content of these flours was in the range of 22.5 24.1%. Fat content was highest in chickpea (4.8%) and lowest in horse gram (1.4%). Resistant starch and phytic acid were significantly higher in cowpea flour. Compared to...
