Abstract



Couscous is a traditional cereal product that is generally produced by coating wheat bulgur with the wheat flour and water or milk in Turkey. In this study, different ratios of legume flours (soy bean flour, SBF; chickpea flour, CF; common bean flour, CBF; lentil flour, LF and lupine flour, LUF), buckwheat flour (BWF), and wheat germ were used in the production of couscous in order to improve the nutritional status. Some selected properties of couscous, such as, colour (L*, a* and b*) weight increase (WI) and volume increase, cooking loss (CL), moisture, ash, crude protein, phytic acid contents, minerals and sensory properties were determined. The addition of BWF and different legumes flours (SBF, CF, CBF, LF and LUF) resulted in higher redness (a*) and yellowness (b*), along with lower brightness (L*) values. Generally, the WI and CL of couscous samples increased significantly (P<0.05) with BWF and legume flour. Also the ash, crude protein, phytic acid, Ca, Mg, K, P, Fe and Zn contents of the couscous increased by BWF and legume flour addition. According to the sensory analysis results, legume flour significantly affected taste-odour, appearance, firmness, stickiness and overall acceptability of couscous (P<0.05). The couscous containing LUF and CF samples had the highest scores for overall acceptability. As a result, BWF and different legume flour can be used in couscous formulation for nutritional enrichment with minimum adverse effect on colour and technologic properties.
