Download or read book Relationship of Selected Wheat Parameters to Arabic Bread Making Quality written by Samer Sami Harb and published by . This book was released on 1997 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty nine wheat (Trhicum aestivunt) flour samples were tested for moisture, ash, protein, sedimentation behavior (Zeleny test. Sodium dodecyl suIfate-SDS-sedimentation volume) and their mixing properties (Mixograph) were also recorded Fractionation of flour proteins into gliadins, glutenins and residue proteins was also performed. The data were correlated with the sensory quality of Arabic bread in order to determine the contribution of flour parameters to Arabic bread quality. Excluding PDR, all mixograph parameters, SDS-sedimentation value and gliadin protein to glutenin protein ratio correlated best with quality of Arabic bread. Flours with mixing times of 3-4 min, tolerance angle of 130-146°, bandwidth at peak dough resistance of 1.5-2.5 MU, resistance to break down 1.0 MU, mixing stability0.7 MU, bandwidth break down 1.2 MU. SDS-sedimentation values45 ml and gliadin/glutenin ratios of 1.5-4.5 are expected to yield high quality bread. In contrast to pan bread. Arabic bread quality did not show a linear relationship with protein content. However, a range of 10-12 % protein is optimum for quality The high correlation between rolling and folding, tearing quality and total scores of Arabic bread suggest that these attributes are the main determinants of Arabic bread quality.
