The feasibility of improving the bread-baking performance of two varieties of Nigerian-grown wheat (Lee X and Inia 66) in pure and compositeflour, using the oxidising agents potassium bromate and ascorbic acid was studied. Composite flour was prepared by mixing pre-cooked bambara bean (Voandzeia subterranea) flour at levels between 0 and 50% with each of commercial (control), Lee X and Inia 66 wheat flour. Physical and sensory evaluations showed that the performance of straight Lee X and Inia 66flours was inferior to that of the commercial flour. The commercial flour showed better tolerance to blending with bambara flour, producing acceptable loaves at up to 20% substitution with bean flour; Lee X and Inia 66 could not tolerate blending beyond 15% and 5 % levels, respectively. Physical properties and baking performance of the Lee X and Inia 66 flours were improved b y treatment with various levels of the oxidising agents KBrO,, ascorbic acid and KBrO,/ascorbic acid combinations. Lee Xflour was more responsive to the treatments than Inia 66. Concentrations of 25 mg kg-1 KBrO, and 80 mg kg-1 ascorbic acid singly were found to improve Lee Xflours adequately, but a combination of the two agents at a level of 25/60 mg kg-' KBrO,/ascorbic acid was optimal. When treated with the optimal level of improver combination, Lee X flour performed as well as the commercial flour; and treated Lee X composite flours containing up to 30% pre-cooked bambara flour were found to produce loaves not significantly different from 100% commercial wheat bread (PSO-05).
