The pH and functional properties: water and oil absorption capacity, bulk density, solubility, swelling power and foaming capacity of tigernut and cowpea flour blends were determined. The flour blends were coded with the letters B, C, D, E, F, G and H for cowpea flour substitutions of 5, 10, 15, 20, 30, 40 and 50 % respectively. For comparison sample A1, A2 and A3 representing 100 % of wheat, tigernut and cowpea respectively, were also evaluated. Standard methods were used for all the analysis. pH of the flour samples varied significantly (P ≤ 0.05) from 5.60-6.23 for sample B (5 % cowpea flour substitution) and A2 (100% tiger nut flour) respectively. Water and oil absorption capacity varied significantly (P ≤ 0.05) from 1.00-2.90 ml/g and 0.39-1.38 ml/g respectively. Sample A1 (100% wheat flour) and Sample B (5% Cowpea: 95% tigernut flour) was significantly (P ≤ 0.05) the highest in water absorption capacity while sample A1 (% wheat flour) had the highest oil absorption capacity. Bulk density varied from 0.58 - 0.84 g/cm3. Although Cowpea flour (sample A3) had the highest bulk density, there was significant (P ≤ 0.05) decrease with increase in cowpea substitution. Swelling power and solubility ranged from 0.08-6.74 g/g and 8.00–67.35 % respectively. Sample A1 (% wheat flour) had significantly (P ≤ 0.05) the highest solubility and swelling power while Sample A3 (% cowpea flour) had the least. The functional properties of the tigernut-cowpea composite flour were comparable with that of the wheat flour, except for the swelling power that was significantly (P ≤ 0.05) higher for the wheat flour. The result showed that the composite tigernut-cowpea flour can be good alternative in the production of bakery products that would not require much swelling.

The feasibility of partially replacing wheat flour with coconut flour in baked products was investigated. Matured coconut (Cocos nucifera) endocarp was grated for the extraction of milk, dried, milled,and pulverized. Five blends of composite flour were prepared by combining wheat flour with 10% to 50% of partially defatted coconut flour,respectively. The 100% wheat flour served as control. The samples were analysed for proximate, mineral, functional,and pasting properties using standard procedures. The proximate analysis indicated 5.52 % moisture, 23.6% protein, 11.14% fibre, 5.4% fat, 5.21% ash,and 49.1% carbohydrate for coconut flour. The ranges of the proximate composition forthe flour blends were:moisture (4.79-5.55%), protein (14.9 -19.1%), fibre (0.44 -5.12%), fat (2.9 -5.3%), ash (0.68-2.13%), carbohydrate (62.7-76.2%),and energy (315.26-335.28 kCal). The values for moisture, protein, fat, fibre,and ash increased with the increasing levels of coconut substitution,except for carbohydrate and energy contents. There were significant differences (p≤0.05) in calcium, magnesium, potassium, phosphorus, iron,and zinc concentrations of the samples. The range of values obtained for these parameters was1.32-2.59 mg/kg, 2.60-3.83 mg/kg, 12.10-16.89 mg/kg, 12.40-18.50 mg/kg,0.50-1.22 mg/kg and 0.30-1.23 mg/kg, respectively. The ranges of functional properties were:loosed bulk density (0.28-0.49 g/mL),packed bulk density (0.44-0.75 g/mL), pH (5.77-6.57), swelling capacity (3.89-6.56%), water absorption capacity (0.89-3.97 ml/g),oil absorption capacity (1.26-3.20 ml/g),and gelation (12.0-18.0%). The pasting characteristics showed significant differences betweenthe100% wheat flour and coconut substituted samples. The results revealed modifications in nutritional, functional,and pasting properties in blends containing fractions of partially defatted coconut flour,which suggeststheir application in diverse food products.

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.

Aim: To evaluate effect of carrot powder addition on the quality attributes of cookies produced from wheat and soy flour blends. Study Design: Cookies were produced from wheat flour, soy flour and carrot powder composite blends. Functional (bulk density, foam capacity, oil absorption capacity, water absorption capacity and swelling index) properties, Proximate (crude protein, ash, moisture, crude fibre, crude fat, carbohydrate and energy value) composition, Physical (weight, diameter, thickness and spread ratio) and sensory (appearance, flavour, taste, texture and overall acceptability) attributes were determined. Results: The functional properties showed that Bulk Density ranged from 0.82 – 0.92, Foam capacity ranged 3.92 – 5.00, Oil Absorption Capacity ranged from 0.60 – 0.97%, Water Absorption Capacity ranged from 1.05 – 1.45% and Swelling Index ranged from 2.37 – 2.75. Results of percentage proximate composition showed that moisture content ranged from 4.70 – 7.57, protein content ranged from 10.61 – 21.60, fat content ranged from 8.89 – 15.85, fibre content ranged from 1.39 – 4.30, ash content ranged from 0.70 – 1.23 and carbohydrate content ranged from 52.34 – 70.84. The physical properties showed that weight of the cookies ranged from 17.85 – 21.60, diameter ranged from 57.50 – 60.50, thickness ranged from 20.50 – 24.00 and spread ratio ranged from 2.40 – 2.91. The sensory attribute showed that cookies produced from wheat flour, soy flour and carrot powder compared well with cookies produced with wheat flour. The wheat flour cookie sample (A) was most preferred by the panellist. Conclusion: The functional properties of the composite flour produced from wheat, soybean and carrot powder show potential quality that when properly harnessed could be used for the production of baked product like biscuits, pastry etc. The proximate composition shows that the composite flour cookies were the most preferred sample to the 100% wheat flour cookies. This is due to its high protein, fat, ash and fibre content to that of thee 100% wheat cookies. However, in terms of proximate composition, the composite cookies were most acceptable. The physical property of the cookies indicates that the composite flour cookies were most preferred to the 100% wheat cookie. This could be seen from the high values it’s had in weight, diameter and spread ratio. However, the sensory score of the overall acceptability shows that the 100% wheat cookies were most acceptable. Though, the composite flour cookies compete very closely with 100% wheat cookies.

Production and evaluation of biscuits made from wheat flour and toasted watermelon seed meal as fat substitute was studied. Extracted watermelon seeds were toasted and grounded into seed meal, which were later usedto formulate composite flour blends in the ratio of 10:90 (MW1), 20:80 (MW2), 30:70 (MW3), 40:60 (MW4) with and 50:50 (MW5) of water melon seed meal: wheat flour respectively, while 100% wheat flour served as control (W1). Each blend was used to produce biscuits adopting robbing process. The functional properties of flour blends, proximate composition and physical properties of the biscuit samples were determined. Sensory qualities of the biscuits were evaluated by 20-members panelist. The accepted composite biscuit samples was stored on a shelf for 6 weeks and analyzed for moisture and total viable count. Data obtained were analyzed statistically (P&le;0.05) for ANOVA, and means separated using Fisher&rsquo;s LSD Test. The results of the functional properties showed variations in behaviour. There were no significant differences (P&le;0.05) in pH, swelling index, viscosity and gelation temperature of the flour blends while significant differences &lsquo;(P&le;0.05) existed in bulk density, water absorption capacity and wetability. There were significant differences (P&le;0.05) in protein, fat, crude fibre, ash and carbohydrate for both flour blends and biscuit samples respectively. The addition of toasted watermelon seed meal increased protein, fat, crude fibre and ash contents while carbohydrate content decreased with higher substitution level of wheat flour. Moisture content ranged from 10-11 % (flour) and 6.25 -10% (biscuit). Significant differences (P&le;0.05) were recorded in thickness, spread ratio and break strength within the samples. The result of sensory evaluation showed that W1I was significantly different (P&le;0.05) in taste, aroma and overall acceptance. However, MW4 and MW5 were significantly different in texture, but in terms of crispiness, MW1 and MW3 were preferred. Moisture content of the preferred samples (MW1 and MW3) stored for 6 weeks increased from 6.25-11.75 % (MW1) and 6.75 &ndash; 11.0% (MW3) while the viable microbial counts ranged from 2.0 x 102-6.8 x 105cfu/g for bacteria and 1.8 x 101-7.4 x 103cfu/g for mould respectively.

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 purpose of this study is to determine the quality of chickpea and black gram flour used in preparation of traditional products. As the study of physical properties of flour, both chickpea as well as black gram flour shows higher in bulk density. Water absorption index show lower level of both chickpea as well as black gram flour and water solubility index shows both chickpea as well as black gram flour in between bulk density and water absorption index. While the functional properties of flour, water absorption capacity lower for chickpea flour but higher oil absorption capacity. Higher the water absorption capacity for black gram flour and lower the oil absorption capacity for black gram. This concluded that bulk density for both chickpea flour and black gram is highest while oil absorption capacity is lower in both chickpea flour and black gram flours.

Most snacks are prepared from basically cereal flours which are nutritionally inadequate. There is the need to complement the nutrient content of these snacks by varying the food sources. Chin-chin snacks were produced from composite flours of Maize, soybean and OFSP with the following formation; sample A (50%: 25%: 25%), B (25%: 25%: 50%), C (25%: 50%: 25%), D (0%: 50%: 50%) and E (50%: 50%: 0%). Wheat flour (100%) served as the control F. The flour bends were analysed for functional properties while the chin-chin snacks were analysed for their nutrient and sensory qualities. The result of functional properties of the flours showed that bulk density of wheat flour (F) was the highest (0.746 g/ml). OFSP flour enhanced the water absorption capacity of the flour blends. Flour blends with soybean recorded higher values in foam capacity (11.20 - 22.55%). In proximate composition, the moisture was low (3.80 – 4.80%) in the chin-chin. Higher fibre content (2.60 - 4.20%) was obtained in samples containing higher proportion (50%) of OFSP. Samples D (19.38%) and C (18.80%) with higher soybean, recorded higher protein values. The mineral and the vitamin contents of snacks from composite flours were higher than that of the control F. Vitamin B1, B2, B3 and β-carotene contents of the snacks were enhanced by OFSP. The sensory evaluation showed preference for snack F (100% wheat flour) followed by snack A (50% maize, 25% soybean and 25% OFSP). However, improved nutrient dense chin-chin snacks were produced from the composite flours.
