  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.

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.

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 market of composite flour is growing as consumer nowadays choosing a healthy diet as personal preference. The suitability of the composite flour for use as intermediate or finish food ingredients highly depends on its physicochemical properties and its nutritional value. In this study, four types of local fruit crops (particularly their seeds) namely rambutan, cempedak, durian and nangka were dried and ground into powder form. The physicochemical properties such as bulk density, pH, water absorption capacity (WAC), oil absorption capacity (OAC), foam stability (FS), foam capacity (FC) as well as gelatinization properties of these composite flour were studied. Mineral content and heavy metal analytes were also determined. Results for bulk density from the least to the higher amount was 0.54±0.00 g/mL, 0.57±0.00 g/mL, 0.58±0.01 g/mL, 0.66±0.00 g/mL , 0.70±0.00 g/mL and 0.72±0.00 g/mL for rambutan flour, cempedak flour, tapioca flour, nangka flour, wheat flour and durian flour, respectively. Both cempedak flour and nangka flour showed the lowest pH value (5.72±0.01, 5.73±0.00), followed by rambutan flour and durian flour (6.67±0.00, 6.90±0.00) which similar to that tapioca flour and wheat flour (6.65±0.1, 6.08±0.0), respectively. Rambutan flour, cempedak flour and wheat flours showed the highest value in% of foam stability meanwhile these composite flours showed the lowest value in% of foam capacity. Results for water absorption capacity (WAC) and oil absorption capacity (OAC) in a range of 6% to 42% and 8% to 12% respectively, however, durian flour obtained the highest value for WAC while the value for OAC was the lowest. All of the composite flour possesses gelling properties at 13% concentration except for cempedak flour which completely gels at 20% of concentration. Rambutan flour showed the highest mineral analyte particularly in Zinc (107.19±0.17) and Copper (14.22±0.27) followed by nangka flour [Zinc (64.20±0.32) and Copper (10.40±0.12)] and durian flour [Zinc (52.38±0.42) and Copper (7.97±0.05)].

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.

Aim: To evaluate the Quality characteristics of Bread produced from Wheat and Kidney Bean composite flour blend. Study Design: Composite bread was produced from wheat and kidney bean flour of various proportions (10, 15, 20 and 25%). Proximate (protein, ash, moisture, fibre, fat and carbohydrate) composition, functional (Bulk density, foaming capacity, swelling index, water absorption capacity and oil absorption capacity) properties and sensory (appearance, taste, flavour, texture and overall acceptability) attributes were determined. Results: Bread was produced from wheat and kidney beans composite (B, C, D and E) flour. The bread samples were subjected to physical, proximate and sensory analyses. The functional properties of the composite flour blends were also determined. The functional properties shows a significant (P<0.05) difference in water absorption capacity, oil absorption capacity and swelling index with values ranged from 1.10 – 0.60 ml/g, 1.03 – 0.76 ml/g and 5.92 – 2.89 ml/g respectively. The bulk density and foaming capacity shows significant (P<0.05) difference with its values ranging from 0.90 – 0.97 g/ml and 32.69 – 26.94 cm3 respectively as kidney beans flour increases. The result of the physical properties shows significant (P<0.05) difference in dough height, proofing rate, loaf volume, specific volume, baking loss and oven spring with values ranging from 1.169 – 3.39 cm3, 0.01 – 0.02 cm3/min, 0.79 – 1.19 cm3, 0.32 – 0.48 cm3/g, 1.59 – 2.79 and 101.58 – 102.79 respectively while the loaf weight ranged from 243.21 – 246.09 g. proximate composition of the sample were also analyzed and the result shows significant (P<0.05) difference in crude protein, moisture content, ash, crude fat, crude fibre and carbohydrate with values ranging from 8.36 – 10.47%, 22.18 – 23.28%, 0.97 – 1.38%, 11.80 – 12.94%, 0.29 – 0.59% and 51.33 – 57.10% respectively. The results of the sensory scores shows a significant (P<0.05) difference in all the samples analyzed. However, sample C with 15% kidney beans flour was most preferred. Conclusion: It could be concluded that increased in kidney beans flour addition in the production of composite bread had significant (P<0.05) impact on the proximate, physical and organoleptic properties of the bread. Hence, 85% wheat to 15% kidney bean flour should be used in bread making.
