【 摘 要 】

The proximate composition, functional and physical properties, as well as sensory evaluation of breads based on blends of wheat and ‘orarudi’ (Vigna sp) flour were investigated. Batches of ‘orarudi’ (Vigna sp) were separately put in a container and subjected to natural lactic acid fermentation in deionized water in a ratio of 1:3 (w/v) at 28 ± 2°C for 24 h. The fermented samples were manually dehulled and the cotyledons dried at 55 ± 2°C in a drought air oven, hammer milled into flour (500 µm mesh screen) and stored in a refrigerator (5 ± 2°C). The blends were formulated thus, the ‘orarudi’ flour (ORF) substituted 5, 10, 15, and 20% wheat flour (WF). The 100% WF served as the control. The parameters investigated were evaluated using standard methods. The data obtained were statistically analyzed. The results showed that fermentation and food supplementation enhanced both the proximate, minerals and vitamin contents of the experimental breads. The physical parameters indicated that fermentation and type of supplements had negative effect on the test breads relative to the control. The results revealed that the experimentalbreads had highernutrientqualitythan the100%wheatbread, probably due .tofood-to-food fortification/supplementation.
