Flour from rice can be applicable into several types of food, or be used directly as a food substitute, and this can have an impact on the final quality of the product. This aimed to determine the functional properties of some selected NERICA varieties, namely, FARO 44, FARO 52, FARO 57, FARO 60 and FARO 61. Results obtained showed that the functional properties, such as the water absorption capacity (WAC), swelling power, water solubility index (WSI), bulk density, oil absorption capacity (OAC), and the foaming capacity, ranged from 251.74 to 298.51 (%); 7.42 to 8.41 (g/g); 10.01 to 12.27 (%); 0.92 to 1.00 (%); 0.45 to 1.36 (%); and 7.29 to 11.76 (%) respectively. All recorded samples were significantly difference (p < 0.05). FARO 61 recorded highest point of 298.51 (%), and 1.36 (%), in WAC and OAC respectively. While FARO 57 recorded the highest swelling power of 8.41 (g/g). These determined results of the functional properties of NERICA flour samples, will be useful in determining their suitability in food and other relevant industries because the flour samples showed high quality range of functional properties that makes them favourable for such activities.

Starches were isolated from cocoyam (Xanthosoma sagittifollium), white yam (Dioscorea rotundata) and bitter yam (Dioscorea dumentorum). Starch modification was carried out using acetic anhydride and phthalic anhydride. The native and modified starches were characterized using Fourier Transformed Infra-red Spectroscopy (FTIR) for identification of the functional groups. Functional properties such as water absorption capacities, oil absorption capacity, swelling power, solubility, gelation temperature, least gelation capacity, amylose content and pH were determined using standard procedures. Acetylation increased the water absorption capacity, oil absorption capacity, swelling power, amylose content, and solubility of the starches while phthalation decreased water absorption capacity, oil absorption capacity, swelling power, and solubility of the starches. Native cocoyam starch has the highest gelation temperature (85 °C) while Acetylated bitter yam has the lowest gelation temperature (74 °C). The pH of the native and modified starches was within the range of 4.14 − 6.55. Phthalation and acetylation increased the bulk density of the starches. Native cocoyam, white yam, and bitter yam starches had the lowest gelation concentration (6%). Modification of native starches will improve the usage of starch in food and non-food applications.

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.

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.
