The possibility of making bread from composite flour containing 60-80% wheat flour, 10-25% cassava flour and 5-15% Sorrel seeds protein isolate was investigated. The proximate composition, mineral constituents, functional and sensory evaluation were analyzed using standard methods.  The results of the analysis showed that crude protein (8.80±0.36 to 18.70±0.35) and crude fibre (0.77±0.02 to 1.58±0.04) contents of the composite breads increased significantly with increased incorporation of cassava flour and sorrel seed protein isolate flours. The moisture (34.00±1.00 to 32.04±1.00), ash (1.22±0.03 to 0.66±0.03), carbohydrate(54.99±0.25 to 46.83±0.77) and fat (0.24±0.01 to 0.20±0.02) contents were  observed  to  decrease  significantly  with  corresponding  increase  in  the  percentage  of  the  composite  flours from 5-25% for both cassava flour and sorrel seed protein isolate flour. The results of the mineral contents showed that calcium element increased as the level of composite flour increased, while sodium, potassium and magnesium decreased as the level of inclusion increased. The functional properties, water and oil absorption, and swelling index of the composite flour showed varying degrees of variation from the control sample (100% wheat flour). The results of the sensory evaluation showed  that there were no significant  differences  (P&gt;0.05)  in taste, texture, colour, flavour, appearance  and  overall acceptability, however, the  mean  sensory  scores  decreased  with increased  addition  of  cassava flour and  sorrel seed protein isolate  in the composite flour.  The outcome of the research showed that, nutritious bread could be produced from the composite flours of wheat, cassava and sorrel seeds protein isolate.Keywords: Bread, Wheat, cassava, Protein Isolate
