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.

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 study established the proximate composition, pasting, and functional properties of cassava flour (CF) blended with chia seeds flour (CSF). Composite flour was prepared by blending CF with CSF in the ratios of 95:05, 90:10, 85:15, 80:20, and 75:25 with CF and CSF used as controls, respectively. The effect of blending significantly (p < 0.05) increased protein, fat, fibre, and ash contents as CSF increased. On other hand, moisture and carbohydrate contents decreased significantly. Pasting properties of composite flour blends decreased significantly (p < 0.05) as the incorporation of CSF increased and a noticeable change was observed for composite flour (75:25) except for peak time and pasting temperature. Functional properties of water absorption capacity (WAC) of CSF were significantly different with CF and composite flour blends. Oil absorption capacity (OAC) of CF and CSF were significantly different, while the composite flour blends had varied OAC due to the inclusion of the different amounts of CSF. The swelling capacity (SC) of CF and CSF were not significantly different, but composite flour blends were significantly different from both CSF and CF. The least gelation concentration (LGC) and bulk density (BD) increased significantly as chia seeds increased. Increased concentration of chia CSF in the composite flour blends showed to alter the functional properties. This study recommends composite flour 75:25 for processing semiliquid products like porridge due to reduced pasting properties values that may be associated with increased energy density compared to CF.

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.
