The effects of cooking and milling of grains from 14 maize cultivars on the characteristics of fine flours were studied in a factorial experimental design. Wet milling significantly increased (P<0.05) fine flour (<400 microns) yields, water absorption capacity at 90°C, solubility index at 25°C, swelling capacity at 95°C and least gel forming concentration. Fine flour composition and functionality were variety dependant. Maize cultivars producing similar fine flours in terms of functionality were classified into three groups: ATP SR-Y, ADV NCRE, CMS 9015, and 88094M131Exp124 for group 1; CMS 8704, CMS 8501, CMS 8806, PDY and ASPY for group 2; and the last group comprising K9351, 87036Exp124, CMS 2019. The specific functional properties maize cultivars should be taken into account in the formulation of pre-cooked weaning food from fine flours.

  This study formulated different flours from sprouted water melon seed and evaluated the proximate and sensory properties akara-analogue potential in Nigeria. The results showed that proximate composition: moisture (7.06-8.46%), protein (19.14%-37.24%), fibre (0.23-0.36%), fat (22.77-26.58%), ash (2.44-3.47%) and carbohydrate (30.58-41.91%) were significantly different at p<0.05. The bulk density ranged from 0.51-0.53g/ml, solubility index (40.30-40.01%), water absorption capacity (1.21-1.25%), swelling capacity (5.32-6.67%), pH (6.13-6.14); for sprouted and non-sprouted samples. Tannins, saponin, sterols, oxalate and phytate were detected in sprouted and unsprouted flour. Sprouting enhanced the amino acid content of composite flour. Mineral contents of Ca, P, K, Mg, Na, Cu, Zn and Mn were increased due to sprouting. The sensory analysis showed that the control samples have the highest taste score (7.35) and aroma (7.60) and were significantly different at p<0.05. Enhanced amino acid composition of watermelon may enhance the use of this flour as protein supplement for the development of new food product.

Bio-based hydrogels that adsorb contaminant dyes, such as methyl orange (MO), were synthesized and characterized in this study. The synthesis of poly([2-(acryloyloxy)ethyl] trimethylammonium chloride) and poly(ClAETA) hydrogels containing cellulose nanofibrillated (CNF) was carried out by free-radical polymerization based on a factorial experimental design. The hydrogels were characterized by Fourier transformed infrared spectroscopy, scanning electron microscopy, and thermogravimetry. Adsorption studies of MO were performed, varying time, pH, CNF concentration, initial dye concentration and reuse cycles, determining that when the hydrogels were reinforced with CNF, the dye removal values reached approximately 96%, and that the material was stable when the maximum swelling capacity was attained. The maximum amount of MO retained per gram of hydrogel (q = mg MO g−1) was 1379.0 mg g−1 for the hydrogel containing 1% (w w−1) CNF. Furthermore, it was found that the absorption capacity of MO dye can be improved when the medium pH tends to be neutral (pH = 7.64). The obtained hydrogels can be applicable for the treatment of water containing anionic dyes.

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.

Akamu, a starchy cereal-based lactic acid fermented gruel consumed in West Africa was prepared using different processing methods: use of dehulled (D) maize grains, use of partially germinated (PG) maize grains (36-48h) and blends: PG and soybean (S) (90:10), D and S (90:10) and D and Melon (M) seed (90:10). Soaking, wet-milling, wet-sieving, sedimentation (24h), decanting, dewatering were involved and the traditional maize akamu served as the control. The seven different samples were subjected to physicochemical microbiological and sensory evaluations. Crude protein (4.70-10.33%), crude fat (4.12-14.30%), total ash (0.26-0.88 %%), crude fibre (1.51-2.77%) contents were higher in oil seed treated akamu and the carbohydrate contents (<74.41%) were the lowest. The akamu made of dehulled(D) maize had poorer proximate composition. Dominant elements in all the akamu were Phosphorous and Potassium and surprisingly, Zinc (1.98mg/100g), Iron (7.33 mg/g) and potassium (106.83 mg/g) in the akamu made with dehulled maize and calcium higher in the control (14.21mg/100g) and partially germinated (14.71mg/100g) akamu. Low water activity in the dried akamu ensured satisfactory low bacterial and fungal counts (<103cfu/g). The control (U) and D akamu possessed better functional and sensory properties; water absorption capacity, swelling power and pH of the different akamu varied significantly: 7.40—8.10 ml/g, 2.74-5.73 g/g, and 5.41-7.42 g/g respectively. Short period of  germination (<48 h) did not affect negatively the proximate composition, sensory, water absorption capacity and swelling power of the PG, PG+U, PG+S akamu(s). The control (U) and D akamu were adjudged to possess better sensory properties especially U akamu with scores slightly greater than 8 on a 9-point hedonic scale, but the superior nutritive value of oil seed treated akamu(s) were masked by poorer sensory attributes. It is concluded that akamu made from PG maize or its blends with undehulled maize or soybean were better alternatives to traditional akamu which is nutritionally inferior although it possessed excellent sensory and functional properties.

Lactic fermentation is commonly employed to improve protein digestibility and overall nutritional quality of grains foods. This study evaluated the functional and rheological properties of flour samples from Bambara groundnut fermented with Lactobacillus plantarum [NRRL B-4306] and Lactobacillus fermentum [NRRL B-1932] obtained from the United States Department of Agriculture. Functional profile such as particle size index, water absorption capacity, swelling capacity, and least gelation concentration of the flour were determined; as well, amylograph and maturograph evaluations were used to determine the rheological properties and the results presented as average, minimum, and maxi­mum values. Particle size determination observed that 150, 125, 105 µ orifice did not readily accommodate particles from the non-inoculated samples while the inoculated samples passed through 150 and 125 µ but did not readily pass through 105 µ orifice. Bioprocess with lactic acid bacteria increased the water absorption capacity of the flour samples from 346.5 to 386.4%, the least gelation concentration decreased from 5.3 to 4.1%, while swelling capacity increased from 14.9 to 23.2 mg/100 g for non-inoculated and inoculated flours, respectively. Rheological investigations show evaluations for amylograph and maturogram determinations. Values obtained for amylograph indicate that temperature at start of gelatinization was peak at 63.8 and 63.00C for non-fermented and LAB-fermented flour with no significant (p ˂ 0.05) difference, while temperature at maximum viscosity and maximum viscosity had significant (p ˂ 0.05) values of 92.1 and 76.00C, as well as 730 and 265 brabender units (BU), respectively. Thus, amylograph quality of the fermented flour sample was indicated by the maximum viscosity which is significantly higher in the case of non-inoculated flour sample. The maturograph evaluation also recorded the maturation behavior of the dough prepared from the test flours after the proofing time (fermentation rest) by means of a sensing probe which records the elasticity of the mature dough every 2 min and produces the typical zigzag form of the maturogram. This action was recorded in maturograph units (MU) on the strip-chart with values of 44 and 28 min for final proof time, 750 and 610 MU for dough level, 210 and 220 MU for dough elasticity, as well as 10 and 12 min for proofing stability, determined respectively for non-fermented and LAB-fermented flour samples. LAB-fermentation demonstrated to improve the functionality and rheology of Bambara groundnut flour and the production process could be further controlled to achieve products of optimal quality.

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.

Aim: Consumption of pupuru (a cassava based food) is on the increasing trend in most parts of Nigeria, hence the need to improve the nutrients with under-utilised legume, African yam bean (AYB). The aim of this work was to co-ferment cassava and AYB at varying proportion and processed to pupuru flour. Study Design: Randomised Block Design was used in this study to assess the influence of different substitution levels of AYB on the properties of pupuru flour and the meal prepared from it. Methodology: The cassava roots were washed, peeled and grated to mash while the AYB was boiled, decorticated and milled into slurry. The AYB slurry was co-fermented with the cassava mash at different substitution level (0, 10, 20, 30 and 40%) and processed to pupuru flour. The 0% served as control (100% cassava). Samples of pupuru flour were evaluated for proximate composition, mineral and anti-nutritional contents. Meal (stiff dough) prepared from the flour was subjected to sensory evaluation. Data obtained were subjected to statistical analysis using SPSS software package. Results: The protein content ranged from 2.9 to 38.68%. The bulk density, swelling capacity, water absorption capacity ranged from 0.72% - 0.86%, 245.56% – 351.84%, and 191.01% - 255.36% respectively. The oxalate, tannin, phytate, and cyanide contents were in the range of 80.00-175.00 mg/100g, 24.55-73.70 mg/100g, 1.34–3.85 mg/100g, and 0.29-0.58 mg/100g respectively. The sensory attributes of pupuru meal indicated a significant difference (p < 0.05) among the samples, with 100% cassava pupuru been the most preferred in terms of taste and general acceptability.
