Available in PDF, EPUB and Kindle. Book excerpt: Regression analysis of the magnitude estimates of 9 manual and 7 oral attributes was utilized to identify' the key textural traits of Arabic bread. The best average coefficient of determination (R") of the triplets predicting the remaining manual attributes and oral attributes were 0.901 and 0.833. receptively. The best triplet for predicting the other manual attributes comprised the force required to initiate tearing, the degree to which the sample extends before rupturing and the pliability of samples. The magnitude of these attributes decreased significantly {P 0.05) upon storage of Arabic bread samples. The resistance to tearing and pliability did not differ significantly between samples of good and medium and were significantly low er in poor quality Arabic bread when assessed after 2 h of baking. The degree to which the sample extends prior to rupturing was found to be an effective discriminator of quality of Arabic bread, with significant differences being detected between samples of different quality, when assessed after 2 h of baking. Significant differences in pliability . resistance to tearing and the degree to which the sample extends prior to rupturing were observed between samples of good, medium and poor quality after aging for 24 h at room temperature. Composite scores of the ratings of the indicated attributes on fresh and 24 h old samples showed significant differences between breads of different quality, These findings suggest that the pliability, resistance to tearing and the degree to which the sample extends prior to rupturing could be adequately used in following the rate of staling in Arabic bread and that a composite score of the ratings of the indicated attributes on fresh and 24 h old samples provides an index for ascertaining differences in quality in this class of baked products.
