| Abstract | ||||
| The present study aims to investigate the effects of the addition of theremally modified wheat flour, thermally modified starch at (160ºC, 180ºC and 200ºC) for 5 hrs. and maltodextrin on the rheological properties of wheat flour dough. From the obtained results it was cleared that addition modified wheat flour to dough increased water absorption, and decreased talerence index, and dough weakening but addition modified starch increased dough stability, and decreased tolerance index. Also addition of modified starch increased resistance to extension, proportional no., extensogram area (cm2) while addition of modified flour increased resistance to extension, proportional no., Extensogram area and decreased extensibility, also maltodextrin addition increased all parameters except extensibility. Meanwhile addition of modified wheat flour increased breakdown viscosity, maximum viscosity. On the other hand, addition of modified wheat flour and modified starch increased falling number in most treatments. | ||||
