AB  - Purpose– The purpose of this paper is to report on a study to produce wheatless bread from acha/fonio (Digitaria exilis) flour with sprouted soybean flour (SSF) using Irish potato starch (IPS) as gluten replacer and determine the sensory qualities of the product.Design/methodology/approach– Acha bread (AB) was baked from acha flour with varying quantities of yeast and IPS added as determined by the 32 factorial design arrangement. Nine different formulations of acha were produced. The loaves were assessed for loaf volume (LV), specific loaf volume (SLV), loaf firmness (LF), proximate composition and consumer acceptability to determine the effect of IPS, yeast and SSF.Findings– The different levels of yeast and IPS gave significant (p < 0.05) changes in firmness of the loaves. A negative effect was observed for yeast and positive effect for IPS. Beyond 4 per cent yeast the effect of yeast on LV was not significant. Hence, the optimal level of yeast was between 2 to 4 per cent. The effect of IPS significantly (p < 0.05) increased the LV. The product with 2 per cent yeast +20 per cent IPS +5 per cent SSF was judged the best recipe for consumer acceptable acha bread. Addition of SSF made the bread softer and significantly increased the crude protein and fibre content of the loaf. The acha bread had apparent yield stress of 286.6 to 546.8 kN/m2 and specific loaf volume of 2.05 to 2.16 cm3/g.Research limitations/implications– A deliberate attempt was made to remove sugar from this product and as such is believed to serve as a good alternative to wheat bread for diabetic individuals and those allergic to gluten. Further research will investigate the functionality of IPS and SSF in AB making and nutritional qualities of the product.Practical implications– The study demonstrates that IPS was effective in retaining gas evolved during baking and that SSF significantly increased the nutritional quality of acha bread.Originality/value– The results of this research contribute to development of specialty cereal based foods for diabetic individuals in Africa and Dominican Republic where acha (fonio) is grown.
