Abstract

In Egypt, bread is traditionally produced from wheat "'Triticum aestivum" flour. Due to high demand, about 50%of
needed wheat is imported. The inability to sustain the national wheat imports for making wheat based foods, makes is
imperative that some substitutes for wheat must be incorporated in the bread preparation. Alternative non wheat cereals
that has capacity to substitute wheat in bread flour in Egypt, includes barley, maize, rice and sorghum The recent study
was carried out to determine the possibility of substituting local wheat varieties flour with rice, sorghum and naked barley
flours. Rice flour substitution blends versus sorghum flour substitution blends contained significantly higher 1.396 protein
units in Misr2 cultivar, 0.469 units in Giza171 cultivar and significant 0.016 units in Gimmeza11 cultivar. In the
meantime, the difference between flour blends that contained rice flour substitution and those contained barley flour
substitution in protein content were reduction of 1.899 units in Misr2 cultivar, 0.526 units in Giza171 cultivar and 0.484
units in Gimmeza11 cultivar. Meanwhile, the influence of fenugreek flour in blends to protein content showed that, less
protein content was associated with fenugreek substitution relative soybean. That reduction reached 0.129 units in Misr2,
0.158 units in Giza171 and 0.137 units in Gimmeza11 cultivar. Substitution of wheat flour by rice flour in blends resulted
in significant increase in dry gluten percentage of Misr2 cultivar reached 0.056% over blends with sorghum flour. While,
blends of Giza171 had significantly 0.233% lower dry gluten. Also, rice/Gimmeza11 flour blends showed insignificantly
0.010% lower dry gluten percentage relative to blends with sorghum flour. Wheat blends with rice flour in comparison to
blends with barley flour, indicated a reduction in dry gluten percentage reached -0.027, -0.332 and -0.227 for wheat
cultivars Misr2, Giza171 and Gimmeza11, respectively. Blend contained substitution with 5% fenugreek flour and 5%
soybean flour contained significantly less 0.078, 0.251 and 0.084% dry gluten in comparison to blends that contained a
substitution of 5% fenugreek for cultivars, Misr2, Giza171 and Gimmeza11, respectively.
