The aim of this study was to explore the effects of
rheological properties of cassava-wheat composite flour dough and also to determine the effect of drying
anti-nutritional factors of Qulle and Kello varieties cassava flours which were obtained fro
research center. The data were statistically analyzed using analysis of variance (ANOVA) in completely randomized
design (CRD). The level of cyanide was found to be
resulted in flours whereas 2.49±0.74 and 1.64±0.08 mg/100g in sun dried Qulle and Kello cassava flour samples, in the
given order. Furthermore, the level of phytate was found to be
Qulle flour samples, respectively while 4.6
given order. The results showed that, the highest value of water absorption and tolerance index of composite dough
samples was recorded 74.10 % and 591.50 FU for 30% sun dried Kello flour containing sample whereas the lowest was
52.5% and 36.50 FU for 10 % oven dried Kello flour, respectively. Furthermore, the highest value of dough
development time, dough stability time, Time to breakdown and Farinograph quality number of composite dough
samples were 5.60 min, 6.05 min, 7.50 min and 75.00 for 30% oven dried Qulle cassava flour containing sample,
respectively whereas the lowest was 1.60 min, 1.10 min, 2.55 min and 25.50 fo
samples, in the given order. It could be concluded that the substitution of cassava flour with wheat flour in dough
making with substitution level up to 20 % did not adversely affect the quality farinograph propertie
comparable to that produced from wheat dough
