The aim of this study was to evaluate the influence gum Arabic incorporation on the proximate composition and sensory properties of biscuits produced from flour blends of wheat and water yam. Water yam was processed into flour and used in composite with wheat flour for biscuit production. Two formulations A and B were produced from the mixture of wheat and water yam flour in the ratios of 50:50 and 30:70, respectively. The two formulations each were used to produce biscuits with different concentrations of gum Arabic (0%, 0.3% and 0.5%) and 100% wheat flour as control. Biscuit samples were subjected to proximate and sensory analysis using standard methods. Increase in the concentration of gum Arabic resulted to an increase in the moisture content (5.63-6.41% and 5.31-6.01%), crude fibre (1.13-1.95% and 2.22-3.40%) and carbohydrate contents (76.96-78.99% and 73.73-77.75%) for formulations A and B, respectively. A decrease in the ash content (3.11-2.85% and 4.60-2.78%), fat (5.35-2.56% and 5.62-2.51%) and protein content (7.82-7.24% and 8.52-8.05%) was also observed as the concentration of gum Arabic increased for formulations A and B, respectively. Result of the sensory analysis revealed that the control biscuit sample was more preferable for colour, taste, flavor, softness and general acceptability while biscuit samples containing 0.5% gum Arabic was more preferred for crispiness and hardness. The result also showed that the incorporation of gum Arabic led to increased sensorial attributes of wheat/water yam composite biscuits. The control sample and biscuit sample containing 30% water yam flour, 70% wheat flour and 0.5% gum Arabic were significantly similar for crispiness, hardness, softness and overall acceptability suggesting that gum Arabic can be incorporated at 0.5% into wheat and water yam composite flour at 70% and 30%, respectively for the production of acceptable and quality biscuits.

Breakfast meals are described as any food obtained with or without supplementation through swelling, roasting, grinding, rolling, or flaking of any cereal. This study is aimed to produce and evaluate the functional, pasting, proximate composition and sensory properties of a breakfast meal made from blends of sorghum, bambara and date flours. Gruels were made using composite flour (450 μm) in ratio of 80:15:5, 70:20:10, 60:25:5 and 100:0:0 for sorghum, bambara and date palm respectively. Samples were assessed for functional, pasting, proximate and sensory properties using standard procedures. Data were analyzed using ANOVA at p = 0.05. The functional properties of the flour blends were significantly (p = 0.05) affected by the increasing level of supplementation of bambara and date palm flour. There was a decrease in gelatinization temperature and viscosity as the level of supplementation of bambara nut and date palm flours increased. The gruel from 100% sorghum flour (control) had the highest pasting properties. Proximate composition of the gruels was as follows: moisture, 10.79-9.22%; crude protein, 4.50-10.37%; crude fat, 1.56-2.12%; ash, 2.86-1.76%; crude fibre, 0.10-0.88% and carbohydrate, 80.33-75.15%. Samples made from 60:25:15 flour blends showed significantly (p = 0.05) highest sensory qualities while gruel from 100% sorghum was lowest. The use of bambara nut and date palm fruits at various substitution levels in the formulation of sorghum breakfast gruel significantly (p = 0.05) enhanced their quality characteristics.

Orange-fleshed sweet potato (OFSP) is a promising root crop due to its high β-carotene content which could help to reduce vitamin A deficiency (VAD). However, it is a less utilized perishable crop. In order to use OFSP tubers, incorporation with other flours in processing and baked products can be considered. The aim of this study is to determine the functional properties of the composite flour, development of extruded snacks using locally fabricated extruder from flour of different blend ratio of OFSP, YRC, Plantain fortified with moringa leaves powder and to determine the proximate composition of the fresh of orange fleshed sweet potato, yellow root cassava, plantain, the flour and the extruded baked snacks.

AbstractOrange-fleshed sweet potato (OFSP) flour is rich in health-promoting compounds that can improve the nutritional benefits of baked products when blended with wheat flour. However, the flour particle size and blend proportion may affect the quality properties and consumer acceptability of bakery products. This study investigated the effect of flour particle sizes and blend proportions on the physical, nutritional, textural and sensory properties of peeled and unpeeled OFSP composite flour cookies. Peeled and unpeeled OFSP flours (≤ 250 μm and ≤ 500 μm particle size) were produced, and each was used to replace soft wheat flour at the rate of 0 to 100% for cookies formulation. The results obtained showed that substitution of wheat flour with OFSP flours significantly (p < 0.05) decreased cookies baking loss, thickness, volume, crust lightness (L*) but increased diameter, spread ratio, crust redness, yellowness, contents of ß-carotene, vitamin A, ascorbic acid, total phenolics and flavonoids, and the antioxidant capacity. The hardness and fracturability of the OFSP-based cookies ranged between 1.389 and 10.142 kg and 0.873 and 9.431 kg, respectively, whereas the values of the control cookies were 1.281 ± 0.003 kg and 1.274 ± 0.003 kg, respectively. The effect of flour particle size on the physical and nutritional properties of cookies was insignificant (p > 0.05). However, the ≤ 250 μm particle size flour cookies had higher overall acceptability than the ≤ 500 μm particle size flour cookies. The unpeeled OFSP composite cookies had higher bioactive compounds concentrations except for ascorbic acid but had lower overall acceptability than the peeled OFSP cookies. Generally, the 30% peeled OFSP composite flour cookies had the highest consumer acceptability.

Ogi was produced from composite flour of fermented Acha, roasted Soybean and Carrot.  The raw materials were blended in varying proportions. Proximate composition, functional properties and sensory characteristics of the formulated Ogi samples were evaluated. The results of the proximate composition showed a significant increase in moisture (5.36% to 9.94%), protein (3.94% to 16.98%), fat (1.89% to 10.23%), crude fiber (1.80% to 3.12%) and ash (0.35% to 0.99%); while a decrease was observed in carbohydrate (86.66% to 58.74%) with increase in supplementation with roasted Soybean flour and constant addition of carrot flour along with the milk flavor. The functional properties showed significant increase in foam capacity (5.99% to 7.97%), Swelling index (2.46 v/v to 3.08 v/v) and Least gelation capacity (8.10% to 14.0%); while a decrease was observed in bulk density (0.84 g/mL to 0.72 g/mL), water absorption capacity (1.40% to 1.10%) and foaming stability (3.39% to 2.79%). Sensory characteristics result revealed that there was no significant difference (p<0.05) in aroma and overall acceptability with increasing incorporation of roasted Soybean flour and constant addition of Carrot flour with milk flavor. Aside the control sample (containing 100% fermented Acha flour) there was preference for Sample C (70% fermented Acha flour: 15% roasted Soybean flour: 10% Carrot flour: 5% Milk flavor) and Sample D (60% fermented Acha flour: 25% roasted Soybean flour: 10% `Carrot flour: 5% Milk flavor) in terms of color (6.65 and 6.25), taste (6.95 and 6.35), aroma (6.45 and 6.30), mouth feel (6.10 and 6.35) and overall acceptability (6.50 and 6.50) respectively, among the blend formulations. Supplementation of fermented Acha with roasted Soybean and Carrot flour considerably increased the protein and fat contents of the blend; hence Soybean should be used for supplementation of cereal based product in order to improve their nutritional composition.
