Abstract

Composite flour blends (acha, defatted soybean and groundnut flour) in the ratio of 100:0, 90:10, 90:5:5, 80:10:10, 70:15:15, 60:20:20 and 50:25:25 respectively were produced and analyzed for chemical properties. Biscuits and cakes were produced from the flour blends and the mineral contents investigated using standard methods. The chemical properties of the blends showed that sugar ranged from 3.66 to 1.53%, starch from 51.78-74.31%, amylose from 18.59 to 38.47%, amylopectin by difference from 30.52 to 45.43%. Moisture content ranged from 9.69 to 12.92%, ash from 0.40 to 1.79%, fat from 0.60 to 9.79%, crude protein ranged from 7.48 to 29.38%, crude fiber from 3.76 to 8.55%, while total carbohydrate ranged from 41.26 to 74.44%. Sugar, amylopectin ash, fat, protein and fiber contents increased while starch, amylase moisture, and total available carbohydrate decreased with increase substitution, indicating a significant (p˂0.05) difference. The mineral analysis result of the biscuit produced ranged from 20.55 to 65.53 mg/kg, 16.17 to 46.20 mg/kg, 7.49 to 13.23 mg/kg, 5.43 to 11.12 mg/kg and 19.59 to 68.59 mg/kg respectively for iron, calcium, potassium, zinc and magnesium. While the mineral content of the cake produced ranged from 13.15 to 44.52 mg/kg, 12.51 to 24.90 mg/kg, 7.42 to 15-21 mg/kg, 6.70 to 14.92 mg/kg and 6.77 to 56.99 mg/kg for iron, calcium, potassium, zinc and magnesium respectively.
