Evaluation of Bread Making Performance of Some Wheat Flour Brands Available in Nigerian Markets as Affected by Cassava or Sweet Potato Flour Inclusion

Abstract

The study examined the baking potential of wheat flour brands available in Nigerian markets and their performance in composite flour bread. Three flour brands were identified and selected based on availability and popularity: Dangote (DG) Bread flour, Golden penny (GP) Prime, and Honeywell(HW) Bakers Delight. Cassava (CV) and Sweet Potato (SP) flours were separately blended with each of the selected wheat flour brands in a ratio of 80:20 to obtain six formulations code named: DG, GP, HW, DGCV, DGSP, GPCV, GPSP, HWCV, HWSP. Breads were produced using AACC straight dough method. Physicochemical and sensory properties of the flours/flour blends were evaluated using approved procedures. The moisture, crude protein, crude fat, total ash, crude fibre and carbohydrate contents of the wheat and root flours were: 5.35-10.10%, 5.78-14.52%,1.79-3.15%, 0.80-2.59%, 1.77-3.15% and 70.83-81.16% respectively. GP flour had significant higher dry gluten (19.00%), water absorption capacity (2.0ml/g) and HW flour had the highest thoroughs (95%) through 212?m sieve followed by Sweet potato (92.50%) yet none met the Codex Alimentarius standard for wheat flour particle size. The specific volumes of the wheat breads varied significantly (p
