The functional, sensory and cooking characteristics of noodles from blends of Acha-tigernut composite flour were investigated. The flour blends and noodles produced were analyzed for functional properties and cooking characteristics. The tiger nut flour was substituted into acha flour at 5, 10, 15 and 20% to produce Acha-tigernut composite flour which was used with other ingredients (salt and powdered ginger) to produce acha-tigernut based noodles. The functional properties of the flour, sensory and cooking characteristics of the noodles produced were determined. The water absorption capacity and swelling capacity increased from 210.59 to 215.53 (g/g) and 524.43 to 586.57, respectively with increase in tigernut flour. While oil absorption, solubility and bulk density decreases from 209.80 to 192.72 (g/g), 10.17 to 5.19 and 0.79 to 0.61 (g/ml) respectively. The swelling capacity ranged from 524.43 to 586.57 (%) with an increase in tigernut flour. The final viscosity of the samples was found to range from 2833.00to 2201.00 (m2/s). The peak properties decreased from 2680.67 to 1580.33 (RVU). The pasting temperature increases from 82.47to 87.57°C. The addition of tigernut decreased the trough, breakdown and peak time from 1730.67 to 1205.67, 985.67 to 434.67, and 5.84 to 5.71 RVU, respectively. The average mean scores for colour decreased from 6.95 to -6.30(%) While that of taste, flavor, texture and general acceptability increased from 5.55 to 6.60, 5.95 to 6.85 (%), 5.95 to 6.44 (%) and 6.70 to 6.83 (%), respectively, as the percentage of tigernut increased.

The present study was undertaken to develop bread from composite flours. Composite flours were prepared by blending wheat flour with watermelon rind flour in ratios of 100:0 (AB1), 90:10 (AB2), 80:20 (AB3), 70:30 (AB4) and 60:40 (AB5), respectively. This study was carried out to ascertain the effects of watermelon rind flour at different replacement levels (0%, 10%, 20%, 30%, 40%) on the proximate and functional properties of composite wheat bread. The results of proximate properties determination on wheat/flour blend gave low bulk densities of 0.54g/cm3 to 0.60g/cm3, high water absorption capacity of 2.389 to 3.044 g/g as well as a high swelling capacity of 5.764 to 7.610 g/g and a low oil absorption capacity of 1.608 to 2.150 g/g. The results of proximate composition of composite bread revealed an increase in % protein, % carbohydrate and % ash from 15.7% to 18.8%, 47.1% to 52.0% and 0.6% to 1.2% respectively and a subsequent decrease in % fat from 18.4% to 13.8. There was a reduction in energy density for composite bread. The functional properties of composite flours such as swelling capacity, water absorption capacity, oil absorption capacity and bulk density were increased with increase in the incorporation of watermelon rind flour with wheat flour. Thus, the results indicate that by incorporating watermelon rind flour, it is possible to enhance the nutritional quality, chemical and functional properties of bread.

This study evaluated flour blends from Wheat, Pearl millet and Andrographis paniculata leaf for functional properties and pasting characteristics profiling. The functional properties such as solubility, gelling capacity, water absorption capacity (WAC), Oil absorption capacity (OAC), Bulk density, foaming capacity and stability and swelling capacity and the pasting characteristics were studied. The inclusion of A. paniculata leaf flour in the blends revealed a significant general increase in water absorption capacity, oil absorption capacity, swelling capacity, and bulk density. However, a general decrease in the foaming capacity, solubility, and least gelation was observed as the inclusion of A. paniculata leaf flour increased. The pasting properties of WPMF (flour blend without the inclusion of A. paniculata leaf flour) exhibited the following values: peak viscosity (658 RVU), breakdown (372 RVU), final viscosity (923 RVU), setback (637 RVU), peak time (5.07 min), and pasting temperature (84.8oC). The inclusion of A. paniculata leaf flour in the blends led to a significant general decrease in all the pasting factors. The inclusion of A. paniculata had a significant effect on the functional and pasting properties of wheat-pearl millet based flour.

Impacts of cooking times (steaming and cooking on embers) on some physico-functional parameters of yam (D. bulbifera) flours cv Dougou-won were determined during 10, 20 and 30 min. Results showed that steaming and cooking on embers increased significantly (P <0.05) the dispersibility (D), water absorption capacity (WAC), paste clarity (PC), water solubility index (WSI), swelling power (SP), least gelation capacity (LGC) and solubility (S) but decreased significantly (P <0.05) foam capacity (FC), wettability (W) and foam stability (FS) of flours (D. bulbifera) cv Dougou-won. Steaming increased significantly (P <0.05) oils absorption capacity (OAC) and bulk density (BD). However, cooking on embers decreased significantly (P <0.05) oils absorption capacity (OAC) but not affected significantly (P <0.05) bulk density (BD). The steaming time (30 min) is recommended to considerably influence the physico-functional parameters of the yam (D. bulbifera) flours cv Dougou-won.

Considering the nutritional and functional characteristics of chickpea, flours of two varieties of chickpea (“Blanco Noroeste” and “Costa 2004”) were prepared to know the effect of cooking. Thus the objective of this study was to compare their physicochemical and functional properties in both, raw and cooked flours. Physical properties of the grain, for the two varieties were similar, whereas the physicochemical and functional properties of the flours exhibited differences as a function of the variety and the processing. The chickpea cooked flours showed lower lightness and higher redness and yellowness with respect to raw flours. The proximal composition of cooked flours presented significant differences in fat (5.98% - 6.09%) and moisture contents (0.48% - 0.54%) with respect to raw flours. The particle size distribution determined for the raw and cooked flours samples, indicated a unimodal behavior with a wide distribution. The water absorption capacity and oil capacity showed significant difference among flour varieties. For pasting properties, a higher viscosity was measured for Costa 2004 (380 cP) and Blanco Noroeste (272 cP) raw flours, raw flour exhibited better pasting properties than cooked flours.

Bambara nut (Vigna subterrenean) is a cheap source of leguminous protein that can be a good substitute for relatively expensive animal protein to reduce malnutrition. Despite its potentials, it remains underutilized owing in part to long cooking time, presence of antinutritional factors and drudgery in dehulling. In this regard, this study determined effects of fermentation on antinutritional and functional properties of bambara nut flour. Bambara nut was procured from local market in Abeokuta while pure culture of Rhizopus oligosporous was obtained at the Department of Food Science and Engineering, Ladoke Akintola University of Technology. Bambara nut was fermented for 12, 24, 36, 48, 60 and 72h at 32ºC and dried in oven (55ºC/24 h). The antinutritional (tannin, oxalate, phytate, and trypsin inhibitor) and functional properties (water-absorption-capacity, solubility and swelling power) of the composite flour were determined. The data obtained were subjected to descriptive and inferential statistics and significance established at P=.05. Respective range of values for tannin, oxalate, phytate and trypsin inhibitor were 0.08 - 0.32, 0.72 - 1.49, 0.15 - 3.64 and 0.42 - 3.25 mg/g, respectively. Water absorption capacity, solubility and swelling power ranged from 8.67 - 11.04, 52.59 - 53.07, 9.20 - 10.16 and 9.14 9.16%,  respectively. The fermentation process reduced the antinutritional factors and increased the protein content.

Abstract Functional properties of Bambara bean protein concentrates (BPCs), as a function of extraction pH and NaCl concentration, were investigated. The results showed that protein content of the concentrates ranged between 69.27% and 74.40%. The addition of NaCl during protein extraction favourably affected water solubility index particularly at pH 10–11. Moreover, the maximum water absorption capacity (4.28 g/g) and oil-holding capacity (OHC) (2.50 g/g) were recorded at extraction pH 11 and in the absence of NaCl. It was also noticed that protein extraction at pH 8–10 was not recommended for applications where high OHC is required. BPCs presenting high emulsifying activity were prepared at NaCl concentration of 0.5 M and pH 7, and at pH 11 without NaCl. Finally, foaming ability (FA) increased with NaCl concentration, and the maximum FA was recorded at pH 7 (114%).
