In this study, the chemical composition and sensory properties of noodles prepared from flour blends of broken rice (R), African yam bean (AYB) and rice bran (B) were determined. A preliminary work was carried out to ascertain the optimal acceptable level of rice bran using 0 to 14% (w/w) addition to rice flour noodle processing. Rice bran yielded the most acceptable noodles at 8% (w/w). Consequently in the main study, the level of rice bran was maintained at 8% (w/w) while AYB and rice flours were varied in the ratios of 100:0:0, 92:0:8, 83:9:8, 64:28:8 and 46:46:8% giving a total of five samples. The noodles were characterized for proximate, mineral contents and sensory evaluation. The protein content of the noodles ranged between 5.8 and 18.4%, increasing with increasing ratios of AYB. Potassium, sodium and magnesium were the predominant minerals in the noodles ranging from 57.00 to 200.40 mg/100g, 1.60 to 105.10 mg/100g and 19.20 to 116.30 mg/100g respectively. Cooking time ranged from 6.0 to 8.3 min with sample 46:46:8R: AYB: B taking the longest time to cook while the control (Rice noodle) cooked fastest. Sample 46:46:8R: AYB: B had the highest sensory scores of 7.3 on a 9 point hedonic scale for General acceptability.
