| Abstract: | The ability of chickpea flour to enrich pasta products (e.g. lasagne) was studied. In addition, the influence of protein and other components upon the rheological properties of the dough and the cooking quality of the wheat–chickpea blends was determined. Supplementing lasagne with 5–20% w/w chickpea flour improves the physical characteristics of dough, which achieves optimum strength and extensible properties thus allowing the lasagne to maintain a firm and elastic form. Organoleptic properties (colour, flavour and overall acceptability) improved with a low proportion of chickpea flour, especially for 5% w/w substitution. For supplementation ≥ 30%, while the content of the total protein increased along with the level of fortification, lasagne processing, handling and cooking characteristics deteriorated proportionally. This could be attributed primarily to the gluten fraction, which decreases upon being diluted by the added chickpea protein. The rheological properties of high supplemented dough products (30–50% w/w) have low extensograph values and the lasagne obtained has a brown colour and a soft mushy taste that is unacceptable to consumers. So, durum wheat flour can carry 5–10% (w/w) of chickpea flour and still meet the specification of pasta products in terms of firmness, cooking quality and sensory evaluation.
