Dakere is a traditional steamed agglomerated dumpling produced from either millet (M) or sorghum (S) flour or both (MS). In the current study, millet and sorghum flours were separately fractionated into fine (f) (<250um), medium (m) (250-350um) and coarse (350-500um) fractions. Similar fractions from millet and sorghum were blended to obtain MfSf,MmSm and McSc. Each fraction was fortified separately with 30% toasted bambara groundnut or sesame seed flour or both (20% bambara groundnut and 10% sesame seed flour), blends were coded: MfSf, MmSm, McSc, MfSfB, MmSmB, McScB, MfSfSe, MmSmSe, McScSe, MfSfBSe, MmSmBSe and McScBSe. Experimental design corresponding to a 3x2x2 factorial design was used to generate runs and dakere were produced applying the traditional method of agglomeration of stiff dough followed by steaming, and thereafter dried. Traditional dakere was the experimental control. The blends and the dried modified dakere were evaluated for proximate composition and sensory properties. The moisture, crude protein, crude fat, crude fibre, total ash and carbohydrate contents of the  blended fractions and the fortified blended fractions varied significantly (p<0-05): 9.40-10.55%,11.42-15.80%,1.20-2.22%, 0.62-0.96%, 3.62-7.38% and 63.56-72.30% respectively and for the various modified dakere: 9.20-10.255, 11.70-16.82%, 1.23-2.77%, 0.55-0.88%, 4.64-8.30% and 60.22-70.86% respectively. Blended fractions and fortified blended fractions had greater nutrient density than the control, however more in the blends containing both bambara groundnut and sesame seed flours. As for sensory attributes of the modified dakere, the blended fractions especially MfSf had the best appearance, fortified dakere the best aroma and taste scores especially dakere with sesame seed meal despite the dull appearance. Dakere produced with blended coarse fractions or fortified coarse fractions were crispier and were desired more than others. The overall acceptability scores were generally high, the highest score observed in the sesame seed meal treated dakere. The study had succeeded in enhancing the nutrient density and sensory properties of dakere, an agglomerated stiff dough through the blending of similar flour fractions from millet and sorghum and fortification of the same with grain legume flours.

The nutrient and sensory properties of malted pre-gelatinized maize supplemented with varying amounts of soy and carrot flour was evaluated. The blends (Malted pre-gelatinized maize flour : Soy flour : Carrot flour) in grams were: A (80: 20: 0), B (73.125: 23.125: 3.75), C (66.250: 26.250: 7.50), D (65.625: 23.125:11.25), E (65: 20:15), F (63.125: 33.125: 3.75), G (63.125:25.625: 11.25), H (60: 25: 15) and I (100:0:0). There were significant (P ≤ 0.5) differences in the proximate composition of the blends. The moisture content ranged between 3.55 - 8.10%. The protein content of the samples increased (P ≤ 0.5) with the increase in soy substitution and varied from 11.61% for the control (sample I) to 21.53% for sample F. The fat, ash and crude fibre content of the blends varied from 1.68 - 10.86, 1.45 - 2.8 and 0.20 - 4.40% respectively. The control had significantly (P ≤ 0.5) the highest carbohydrate content of 75.61%, while it varied between 55.30 and 71.60 % for others. The energy values varied from 360.43 - 405.00 Kcal/g. The sensory scores were based on a 9-point hedonic scale, with 1 and 9 expressed as dislike extremely and like extremely. The assessors’ likeness for the sensory attributes (colour, texture, taste, aroma and general acceptability) was below neither like nor dislike. This study revealed that substitution with soybeans and carrot flours increased the nutrient composition of the malted pre-gelatinized maize, soybean and carrot flour blends. Particularly the soy flour as sample F with the highest soy flour substitution (33. 123g) had significantly the highest protein (21.53%), fat (10.86%) and energy (405 Kcal/g) values. This would be recommended for good quality porridge. Although, the sensory analysis revealed the need for further investigation on processing methods especially the malting process as to enhance the overall acceptability of the product.

The study evaluated the proximate composition and sensory properties of fruits (banana and tomatoes) and vegetables (Lettuce and cabbage) from an open market and a shopping mall to ascertain the effect of the two environments on the sample quality. Standard analytic procedures were used in sample analysis. Open market samples had moisture, protein, fat, ash, crude fibre and carbohydrate content of 76.56-92.96, 0.25-1.24, 0.03–0.91, 0.56–1.17, 2.20–3.34 and 1.17 – 14.13 % respectively, while values for shopping mall were 80.62-94.10, 0.16–0.29, 0.06–0.21, 0.40–0.86, 1.54–3.87 and 0.91–14.28 % respectively. The degree of likeness for the appearance, flavour (aroma/taste), texture (firmness/crunchiness) and overall acceptability of the samples from the open market ranged from 6.60 - 7.00, 4.90 - 6.35, 5.25 -5.95 and 5.80 - 6.10 respectively, and those of the shopping mall were 6.55–7.25, 4.70–6.65, 5.45–5.95 and 5.85–6.30 respectively. The environment had significant (P≤0.05) influence on the proximate composition and sensory properties of the fruits and the vegetables. Fruits and vegetables from the open market had significantly (P≤0.05) higher nutrient content. The environment of the shopping mall provided the low temperature which improved upon the moisture and sensory attributes of the samples as evidenced in higher degree of likeness of samples from the shopping mall. This revealed the importance of storage and sales of fruits and vegetables under chilled storage.

Cooking of bambara groundnut is time and energy consuming. This research was therefore carried out to find a way of reducing the cooking time of bambara groundnut and at the same time reduce losses of nutrients. Green pawpaw slices, both fresh and dried were added to the raw bambara groundnut and cooked. The treated Bambara groundnut recorded the lowest cooking time (P<0.05) compared with the untreated. The treatment did not have any effect (P<0.05) on the calcium, and phosphorous contents, but rather led to increased levels (P<0.05) of crude protein, crude fat and iron but reduced levels of carbohydrate, crude fibre and ash content. However, the untreated Bambara groundnut gave the best sensory properties and hence the best overall acceptability. The findings of the research when applied, has the potential to reduce fuel consumption and conserve the environment.Keywords: Green pawpaw; Bambara groundnut; cooking; dry pawpaw slices; crude.

Chin-Chin, a traditional Nigerian snack was prepared utilizing wheat-fermented maize residue composite flour at 0 – 30% replacement levels. Effects of this addition on the functional and pasting properties of the flour composite was evaluated. The snack produced was also evaluated for its sensory attributes, proximate composition and invitro-protein digestibility (IVPD). Functional properties results showed an increase in water absorption capacity (WAC), a decrease in oil absorption capacity (OAC), decrease in Bulk Density (BD), swelling power and solubility index with residue addition. Pasting property results showed a drop in the value of peak, trough, breakdown and final viscosity with substitution while set back viscosity increased.Peak temperature decreased, but values for pasting temperature showed no significant difference between the control and the blends. Results for sensory evaluation showed equal preference for overall acceptability. Proximate composition results showed residue addition led to an increase in crude fibre and protein content with a drop in the carbohydrate value. Residue addition did not increase protein digestibility. Addition of fermented maize residue in chin-chin production can be another way of utilizing the fibre rich by-product of the production of fermented maize starch.

The levels of proximate composition, minerals, antinutrients, fibre components and calculated parameters for mineral bioavailability were determined in the testa, dehulled and whole seeds of Bambara groundnut on dry weight basis. Proximate levels were (g/100 g): ash (2.46- 4.36); crude fat (2.47-6.99); crude protein (15.2-22.2); crude fibre (1.03-22.9) and carbohydrate (51.6-61.9). The non-starch polysaccharide (NSP) components were (%): ADF, 7.13-29.0 (or 16.1 %-65.5 %); NDF, 1.77-23.6 (or 6.28 %-83.7 %); ADL, 6.15-28.0 (or 14.9 %-67.8 %); cellulose, 1.36-23.3 (or 5.02 %-86.0 %) and hemicellulose, 0.84-26.5 (or 2.86 %-90.1 %). In minerals (mg/100 g): Mn, Co and Cu were not detected; Na, K, Ca, Mg, Fe and P were low in values whereas Zn was high at 11.2-40.2. These parameters were also good for human health: Na/K (0.47-0.51) and Ca/Mg (2.58-4.36). Antinutrient values showed that Phy was high (14.4-29.2 mg/g); oxalate was high (5.02- 8.59 mg/g) and unavailable phosphorus as Pp % of P (10.2-49.3 %). The mineral bioavailability showed Ca/Phy to be good at 0.20-0.89 and [Ca] [Phy]/[Zn] to be good at 0.09-0.23 thereby making Zn bioavailable in all the samples.

This study evaluated some quality attributes of pancakes from peeled and unpeeled sweetpotato flours and cassava starch. Cassava starch was substituted up to 30% of the total composite flour. The proximate composition, colour, carotenoid and functional properties of the different flour blends were determined. The flour blends were processed into pancakes and the proximate composition and sensory acceptability of the pancakes were determined. Data obtained were subjected to analysis of variance. The result showed that they were significant differences (p<0.05) in the functional properties of the flour blends. Bulk density, Water absorption capacity, Oil absorption capacity, swelling capacity ranged from 0.70 to 0.78 g/ml, 1.87 to 2.30 g/ml, 1.02 to 1.40 g/ml and 5.18% to 6.66%  respectively. There were significant differences (p<0.05) in the proximate composition of the pancake samples. The values ranged from 42.76 to 45.53%, 2.13 to 3.98%, 9.06 to 10.34%, 5.01 to 7.18%, 3.75 to 6.01% and 29.19 to 35.33% for moisture, ash, fat, protein, crude fibre and carbohydrate contents, respectively. Pancake produced from 100:0 peeled and unpeeled sweetpotato flour had the highest score for overall acceptability which can compare favorably, with pancakes from wheat flour which is the control sample. In conclusion, sweetpotato flour blended with cassava starch at different ratio gave good proximate and functional properties which resulted in pancakes of good quality attributes.

PurposeThis study aims to investigate the effects of incorporating seaweed composite flour on soft roll dough rheological characteristics and quality.Design/methodology/approachIn this study, wheat flour was substituted with seaweed powder obtained from red seaweed (Kappaphycus alvarezii) at varying proportions (100:0; 99:1; 98:2; 97:3; 96:4; 95:5, 94:6, 93:7 and 92:8) and applied in soft roll production. The effects of seaweed composite flour were evaluated in terms of rheological characteristics, proximate composition and physical properties. The sensory characteristics of the soft rolls was evaluated by 40 untrained panellists by using a hedonic scale.FindingsFarinograph analysis of the soft roll doughs showed that the incorporation of seaweed powder promoted an increase in water absorption, development time and mixing tolerance index, whereas it decreased stability time. Analysis of the proximate composition of the soft rolls showed that protein and carbohydrate contents decreased, but moisture, ash and crude fibre contents substantially increased. Dietary fibre increased with the increase in the proportion of seaweed powder added. The specific volume, bulk density and firmness of the soft rolls ranged from 3.01 to 5.48 cm3/g, 0.18 to 0.33 g/cm3 and 1.86 to 20.63 N, respectively. Sensory evaluation results showed that the mean score of sensory attributes decreased as the proportion of seaweed powder added was increased in the formulations. With regard to the overall acceptability, the panellists preferred the soft rolls with the least amount of seaweed powder added. The results of hedonic tests revealed that the panellists' acceptance decreased as higher amounts seaweed powder were added in the formulations.Originality/valueThis study showed that the seaweed powder of K. alvarezii can be utilised as an ingredient to improve the nutrient composition of baked products.

Advocacy on the utilization of locally grown crops keeps increasing. This study was however carried out to evaluate the qualities of extruded snacks from blends of yellow cassava and sesame seeds flour. The yellow fleshed cassava roots and sesame seeds (germinated and fermented) were dried, milled and sieved prior to further analysis. Flour of each of the processed sesame seed was blended with yellow cassava flour at substitution levels of 0, 15 and 30%. Functional and anti-nutritional analyses were carried out on the flour blends. The flour blends were mixed thoroughly to produce extruded snacks in a single screw extruder before frying in a deep fryer. Anti-nutrient, proximate and sensory evaluations were carried out on the extruded snacks. There was considerable increase in the functional and proximate compositions with an increase in sesame seed flour incorporation most especially samples with 30% fermented sesame seeds flours, but with a considerably low anti-nutrient in the extrudates. Extruded samples with 30% Fermented sesame seed flour also had the highest (7.20) rating with regards to the overall acceptability closely followed by extruded snacks from 100% yellow cassava flour (7.05) and samples with 30% germinated sesame seeds flour. The results indicated significant differences (p<0.05) among the samples. This research revealed that extruded snacks can be produced from non-wheat flours which will reduce over dependence on imported wheat and hence increase the utilization of locally grown crops. It will contribute to large scale production and utilization of the crops for enhanced national food security.

In this study, attempt was taken to increase the functionality of cake by substituting wheat flour with 10%, 20%, and 30% jackfruit seed flour (JSF). JSF contained 6.29% moisture, 13.23% protein, 3.09% crude fibre, 73.42% carbohydrates, 2.72% ash and 1.25% fat, and wheat flour contained 12.86% moisture, 1.2% ash, 10.76% protein, 1.32% fat, 1.4% crude fibre and 72.46% carbohydrate. Three cake samples were prepared with composite flour (JSF and wheat flour)mixed with other ingredients and compared with a control sample. The specific volume of cake for 20% substitution was higher than that of all other cakes. The crust and the crumb characteristics changed with the incorporation of JSF. Proximate composition of the cakes like carbohydrate, ash, fibre and protein increased with the substitution of JSF, butfat and protein decreased. Nutritionally, composite cakes with different levels of JSF were found better than control sample. In sensory tests, significant changes were found in color, flavour, texture and taste, and overall acceptability of cakes were observed with the increase of substitution. However, cake with 10% JSF incorporation got the highest acceptability by the panelists.J. Bangladesh Agril. Univ. 14(2): 219-227, December 2016
