The study examined the chemical and functional properties of composite flours based on maize, Bambara groundnut, and mango for possible use as complementary food. Flours were prepared from yellow maize variety, Bambara groundnut and mango pulp and blended in the ratios 100/0/0, 90/5/5, 85/10/5, 75/20/5, 70/25/5 and 65/30/5 labelled as samples A, B, C, D, E and F respectively. Standard methods were used to evaluate the composite flours and the control for functional properties, and chemical properties. Analysis showed an increase in the moisture content, proteins (19.28% in sample A to 23.81 % in sample F), lipids, carbohydrate. Crude fibre content ranged from 2.97% in Sample F to 1.91% in Sample A. Ash content generally increased from 1,62% in sample A to 2.58% in sample F. Phosphorus, Calcium and Potassium showed an increasing trend as follows; (154 mg/100 g in sample A to 186.86 mg/100 g in sample F), (392.67 mg/100 gin sample a to 399.94 mg/100 g in sample F), (183.56 mg/100 g in Sample A to 192.02 mg/100 g in Sample F) respectively. Provitamin A and ascorbate showed significant increase in the composite flours than the control. All anti-nutrient compositions in the samples were within tolerable levels There was no significant difference in the swelling indices of the different flour blends; the highest water absorption capacities were seen in sample F (1.36 g/ml) while the lowest was seen in the control sample A (1.15 g/ml). Water absorption capacity therefore showed an increasing trend with increasing substitution of maize flour with BG flour and mango powder. Results showed that supplementing Yellow maize flour with Bambara groundnut flour and mango powder considerably improved the protein content of the flour, hence they can find useful application for ogi production.

The need to improve and enhance the nutritional quality of locally made foods (bakery and confectionaries) cannot be overemphasized. This study set out to meet this need by producing composite flours from wheat, defatted peanut and orange peel flour blends which will serve an even greater issue of reducing the cost of wheat importation and use. The samples were coded as follows: A-100:0:0, B-90:5:5, C-85:10:5, D-80:15:5, E-75:20:5 of wheat flour: Defatted peanut flour: orange peel flour. The flours produced were analyzed for functional, anti-nutrient, proximate, minerals, and phytochemical properties. The functional properties of flours; bulk density, swelling capacity, OAC, WAC, and Foaming capacity ranged from 0.43 to 0.93 g/ml, 0.89 to 5.67%, 0.47 to 2.55 g/L, 1.75 to 4.35ml/g, 0.52 to 10.56% respectively. The anti-nutritional properties: phytates, tannins, and trypsin inhibitor content of flours ranged from 0.0352 to 0.0845%, 0.040 to 0.600%, and 0.011 to 0.048mg/g respectively.  The proximate composition of the flour samples, Moisture, Protein, fats, crude fibre, ash, carbohydrates, and energy values ranged from 5.58 to 9.55%, 6.33 to 15.64%, 1.06 to 3.51%, 0.24 to 4.07%, 1.42 to 2.65%, 85.37 to 64.58% and 376.34 to 352.47kcal/100g respectively. The mineral composition in the samples ranged from 232.05 to 394.62mg/100g for Ca, 76.09 to 122.27mg/100g for Mg, 6.71 to 29.42 mg/100g for Fe, 108.78 to 256.47mg/100g for K, 10.09 to 25.75 mg/100g for Zn. The phytochemical composition of the samples was as follows; 0.067-0.153%, for saponins; 0.043-1.457%, for alkaloids; 1.03-13.77mgGAE/g, for Total phenolics; 3.07-29.31mg/QE, for Total Flavonoids respectively. The composite flour herein produced demonstrates great potential for its use in the development of functional foods given its great nutrients and improved functional characteristics. However sample E with 75%wheat: 20%DPF: 5%OPF surpassed all other samples in terms of the quality attributes and therefore was the best of the formulations.

This study evaluated the effect of adding ginger flour on the storage stability of soymilk. Fresh ginger rhizome was processed to flour by oven drying (OD), sun drying (SD) and ambient drying (AD).The ginger flour were incorporated into processed soymilk at 1 g and 2 g levels, respectively to obtain ginger spiced soymilk, which was stored for 21 days. The chemical composition and microbiological load of the soymilk were determined. The pH ranged from 6.6 to 4.7. The values decreased as storage time progressed. Total titratable acidity (TTA) ranged from 0.0015 to 0.0698 % and increased with storage time. Total soluble solids (TSS) decreased from 26.60 to 3.99 oBrix as storage time increased. Total solids (TS) decreased from 7.76 to 0.31 % during storage. The total viable counts of the control sample increased from 4.0×103 to 71×103cfu/mL while those of the treated samples increased from 0 to 33×103 cfu/mL, Coliform was not detected. Yeast and mould growth did not occur from day 0 to day 7 but increased from 2.0×103 to 5.0×103 cfu/mL on day 14 and 21, respectively. The highest microbial load was obtained in the control soymilk sample. Two grams of ginger flour preserved the soymilk better than one gram. As conclusion, the incorporation of ginger flour affected the chemical composition and microbial load of soymilk during storage at refrigeration conditions.
