Coconut has a unique taste and aroma and excellent dietary fibre which has potential application in baked products and human nutrition. Bread was baked using wheat flour and coconut flakes at different substitution levels 100% wheat flour (AWB), 80% wheat and 20% coconut flakes (CWB8), 85% wheat flour and 15% coconut flakes (CWB8.5) and 90% wheat flour and 10% coconut flakes (CWB9). Some quality parameters such as proximate, mineral, pasting, sensory and microbiological analyses were determined to find out the most appropriate substitution level that can give better acceptability. The results showed that proximate contents of samples increased with substitution level. Protein content ranged from 12.63% to 10.26%, fat from 2.23% to 6.13% and fibre from 0.23% to 0.29% respectively. There was a significant difference (p< 0.05) in the Calcium content of the flour blends with 20% coconut flakes (CWB8) having the highest value of 16.94m/kg while the control had the lowest value of 10.93mg/kg. Same trend was observed in the magnesium and potassium contents. The pasting properties revealed that 20% blends (CWB8) had the highest peak viscosity, through breakdown and final viscosity. The peak viscosity ranged from 1681 RVU to 2580 RVU and final viscosity from 1689 RVU to 2645 RVU when compared with the control which has 1814 RVU. Sensory evaluation results showed that CWB8 is the most preferred for all attributes determined when compared with other samples. Microbiological study showed that microbial counts of CWB8 had the highest value of 2.66 x 105 cfu/g at ambient temperature which was higher than the permissible limit within one week while samples stored in the fridge and freezer had low microbial counts. From this study, enrichment with coconut flakes increased the nutritional benefits of the bread because of the increased protein and dietary fibre contents which acts as a prebiotic that helps probiotic bacteria thrive and encourages optimal digestion helping to prevent constipation.

Additions of barley flour alone or with combination of chestnut and acorn flour (30%; 30+5%; 30+10%) were aimed at increasing the dietary fibre content in wheat bread. In this regard, enhancement by acorn flour elevated the dietary fibre by a greater extent (up to 7.80%) compared to barley or chestnut flours. Increasing the proportion of non-traditional raw materials also influenced flour pasting properties during the amylograph test as well as the farinograph and extensigraph properties of non-fermented dough. In contrast to the wheat flour, analysis of Falling Number and Zeleny values showed a decrease in technological potential of flour composites of approximately 30%. Water absorption increased about 2 percentage points, mainly with enhancement by chestnut flour. All the non-traditional raw materials slowed dough development, whilst dough softening degree differed according to actual composition. Dough viscous and elastic properties worsened as shown by a decrease in energy absorbed, depending on the type and the addition of the non-traditional products. Changes in flour composition were reflected in amylograph viscosity maximum, which became lower with increasing amounts of chestnut and acorn flour. A significant worsening of the bread specific volume as well as of bread shape (vaulting) corresponded with a partial dilution of the gluten matrix. Compared to the wheat bread, 10% chestnut flour caused bread size to diminish to less than one half of the wheat loaf. Statistically, the principal features were water absorption, dough softening degree and extensigraph energy together with specific bread volume. In terms of wheat flour and bread quality, the influence of barley flour overcame the effects of adding chestnut or acorn flours.

The demand for food products with functional attributes is on the increase worldwide. The present study was aimed at evaluating the effect of supplementing whole wheat flour with 0, 10, 20, 30, 40 and 50% whole green plantain flour on pasting properties of the flour blends, proximate composition, minerals and sensory characteristics of crackers made from the blends. The 100% whole wheat flour served as the control sample. The result showed that the peak viscosity (PV), trough viscosity (TV), breakdown viscosity (BDV), final viscosity (FV) and setback viscosity (SBV) were significantly affected by the level of plantain flour substitution. The 20% plantain flour substitution level recorded the minimum PV (264.00RVU), TV (248.00RVU), FV (531.00RVU) and SBV (263.00RVU) while the 50% plantain flour substituted blend recorded the highest PV (362.00RVU), TV (328.00RVU) and FV (603.00RVU). The control sample recorded the highest SBV (312.00RVU) and least BDV (3.00RVU). The peak times for all the blended samples were the same (7 min) while the time for the control sample was 5 min. There was insignificant difference (P>0.05) in the pasting temperature which ranged from 91.30 – 92.80oC. The crude protein, fat and calcium contents progressively decreased while the ash, crude fibre, carbohydrate, K, Mg, Fe and Zn contents in the prepared crackers progressively increased with increase in the proportion of plantain flour substitution. Cracker prepared from the blend of 80% whole wheat and 20% whole green plantain flours was the most preferred by the sensory evaluation panellists in terms of taste, texture and overall acceptability. It is evident from the study that acceptable crackers of enhanced nutritive value could be produced from blend of 80% whole wheat and 20% whole green plantain flours. The use of flour from unpeeled plantain as ingredient in cracker production would eliminate waste generation and its associated environmental problems.

The aim of this work was to produce biscuits from wheat flour substituted with different amounts of wheat sprout powder (2.5–7.5%). The biscuits were subjected to chemical, phytochemical, and microbial evaluations. The crude protein, fat, and ash contents and the energy value of the biscuits increased with increasing percentage of wheat sprout powder. Adding sprouts resulted in higher values of phenolics, alpha-tocopherol, and antioxidant activity. There was no statistically significant difference in the contents of total phenolics and alpha-tocopherol between biscuits supplemented with 5% sprouts and biscuits substituted with 7.5% sprouts. The phenolic content in biscuits containing 7.5% sprouts was 245 mg gallic acid equivalents (GAE)/100 g dm compared with 110 mg GAE/100 g dm in control biscuits. Antioxidant activity was the highest in biscuits substituted with 7.5% sprouts. All levels of substitution of wheat flour with wheat sprouts had an effect on the nutritional properties of biscuits, but the substitution level of 2.5–5% is recommended for the improvement of their sensorial properties. The biscuits produced had a low microbial load and were microbiologically safe. Escherichia coli, Salmonella spp., and sulfite-reduction clostridia were not detected in any sample during the period of investigation from 2 to 60 days of storage.

Kañawa (Chenopodium pallidicaule Aellen) is an Andean crop harvested in Bolivia and Perú. Because of the characteristics and properties of kañawa seed, its flour can be used to replace partially wheat flour in pasta to increase its nutritional value. The objective of this study was to investigate the production of fiber- and protein-enriched pasta made with wheat and kañawa blends. The effect of the substitution level of wheat by kañawa flour on pasta quality was evaluated taking into account the influence of kañawa composition on starch behavior and gluten network formation. Proximal composition, thermal behavior, and pasting properties of kañawa and wheat flours were determined. Pasta was made from wheat flour (control) replacing 10, 20, and 30% of wheat by kañawa flour from L1 and L2 ecotypes. Water absorption and cooking loss were increased showing the deleterious effect of kañawa flour on pasta quality, but the L1 ecotype showed better performance in cooking properties. Kañawa pasta firmness and chewiness decreased with the kañawa content increase; however, the L1 ecotype did not modify the firmness when 10 and 20% were included in pasta. Both kañawa flours improved the nutritional quality of pasta, increasing the dietary fiber content and protein quality.

The paper examines the effect of native and germinated pumpkin and watermelon seeds on the quality of semi-finished and finished bread products. Native and germinated seeds, pre-dried and ground into flour, were used as an additive to bread in the amount 5%, 10%, 15% by weight of the flour. Pumpkin and watermelon seeds were added in order to enrich the bread with micronutrients. The influence of these additives on the quantity and quality of gluten has been analysed. It has been found that the addition of pumpkin seed flour in quantities of 5%, 10% and 15% by weight of wheat flour leads to a decrease in the gluten content and an increase in its elasticity. The study has shown that adding native pumpkin seeds does not have a significant effect on the moisture and acidity of semi-finished and finished products, and adding germinated seeds leads to a slight increase in these parameters. Thus, the moisture content of the crumb with native pumpkin and watermelon seeds added increased by 0.2–1.3%, as compared with the reference sample, and with germinated seed flour added, it increased by 0.5–2.2%. The acidity of the crumb changes slightly, within experimental error. According to the physicochemical quality parameters, the most practical amount of the additives is 5% by weight of wheat flour. A comparative analysis has been carried out to establish how addition of 5% of native and germinated pumpkin and watermelon seeds changes the organoleptic properties of bread. The analysis has shown that ready-made bread products containing native pumpkin seeds taste better and have better olfactory properties than products with germinated seeds. The nutritional and calorific values of the reference sample and of bread with 5% of pumpkin and watermelon seed flour have been compared and characterised. It has been found that the addition of native pumpkin seeds will increase the content of minerals: of iron by 230%, of magnesium by 116%, and of potassium by 118%. The addition of native watermelon seeds will increase the phosphorus content by 13%. As a result of this research, the prospects of using flour of native pumpkin and watermelon seeds to fortify wheat bread have been shown

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.

Aims: The aim of the study was to evaluate the physicochemical, sensory and functional properties of coconut flour (CF), coconut wheat composite flour (CWCF) and Cake produced from CF and CWCF. Methodology: Flour was prepared from matured ripe coconut fruit (CF). It was then blend with wheat flour (WF) into coconut wheat composite flour (CWCF) to produce cake. The CF and CWCF were subjected to proximate composition and functional properties analyses. Also, the physical properties, proximate composition and the sensory attributes of the cakes produced from CF and CWCF were determined. Results: The moisture content of CF and CWCF ranged from 4.5 to 9.04 g/100 g, the ash content of CF and CWCF ranged from 4.10 to 6.41 g/100 g and the dietary fiber content of CF was 11.16 g/100 g. CWCF exhibited a higher (87.1± 0.6) water absorption capacity and packed bulk density (0.79 ± 0.3 g/ mL). In this study, the cake volumes increased significantly (P < 0.05) in wheat flour (WF) as compared to CWCF and CF. The specific cake volume observed ranged from 1.48 to 2.01 mL/g. The blend of 50% coconut and 50% wheat flour increased significantly (P < 0.05) the moisture content of the CWCF cakes. The total carbohydrate content of the cakes varied from 20.40 ± 0.02 g/ 100 g to 63.05±0.14 g/ 100 g. Fat, ash and crude fiber and minerals (Ca, K, P Zn, Mg and Fe) increased in CWCF cakes. The sensory analysis conducted showed that there was a significant difference (P < 0.05) between CF cakes, WF cakes and CWCF cakes in the sensory qualities of appearance, texture, flavour and overall acceptability. In terms of appearance, the panelists scored coconut cake highest, but was significantly different (P < 0.05) from coconut wheat cake and wheat one. The least liked sample in terms of texture was wheat one. Conclusion: The present study underscored the potential application of coconut flour in the production of cake and possibly other bakery products.

Composite flour/bread technology is an important area to be properly harnessed in food industries to help reduce the cost of wheat importation in Nigeria. In this study, bread produced from composite flours using Saccharomyces cerevisiae isolated from local fermented beverage (Burkutu) was investigated. Sugar fermentation, carbohydrate utilization and ethanol tolerance tests were carried out in identifying and characterizing the yeast isolates. Composite breads were produced from Wheat Flour (WF) (100%) and its blends with Rice Flour (RF) (40%), Plantain Flour (PF) (40%) and Cassava Flour (CF) (40%) using the straight dough method. The yeast survived in 25% glucose and 15% ethanol, suggesting its usefulness in industrial application. Loaf weights and loaf volumes of the composite bread samples ranged from 318.4 - 355.7 g, and 420.6 - 457.3 mL respectively, with 100% Wheat Bread ranking highest while Composite rice bread the least, using a significant difference of P<0.05. The total yeast count recorded after 4 days showed 0.25 x 10-3 CFU/mL (100% W bread), 0.40 x 10-3 CFU/mL (W/R (bread), 0.21 x 10-3CFU/mL (W/P bread) and 0.32 x 10-3CFU/mL for W/C bread. Sensory assessment revealed that there was no significant difference (P>0.05) in the bread samples analysed. Shelf life assessment of the bread samples at room temperature (26±1oC) within the first three days revealed no microbial growth/cell count. Bread produced from the incorporation of cassava with wheat flour was found to be acceptable, with insignificant variation when compared to bread made with 100% wheat flour.

The evaluation of the chemical (proximate composition, mineral composition, toxicant composition and vitamin composition), nutritional and industrial potentials of two varieties of cocoyam (Xanthosoma sagittifolium (XS) andColocasia esculenta (CE) were carried out using recommended methods of analysis. Baking trials were conducted with the two varieties of cocoyam at different levels of substitution (20%, 30% and 50%). The produced bread samples were analyzed for their physical parameters and proximate composition. Sensory evaluation test was also carried out on the produced bread. The result of the analysis showed that the preferred bread in terms of loaf weight, volume and specific volume was given by sample I (control sample) containing 100% wheat flour with a specific volume of 3.54 cm3/g. This was closely followed by sample A with specific volume of 3.25 cm3/g containing 20% substitution level ofCE. Sample H containing 50% substitution level ofXSwith specific volume of 2.58 cm3/g gave the poorest performance. The sensory evaluation result further revealed that apart from the 100% wheat flour based sample I, sample D with 20% substitution level ofXSwas rated good and maintained better performance amongst the cocoyam varieties while samples G and C with 100% and 50% substitution level ofCErespectively were rated the poorest. The proximate composition of the bread samples was also carried out.CE, XSand wheat bread samples (100%) recorded 15.0633±1.4531, 12.1133±1.5975 and 11.2867±0.7978 respectively for the moisture content.XSbread recorded the highest carbohydrate content of 45.0133±3.0274. In terms of ash,CEbread recorded the highest value of 31.4367±1.6159 while wheat bread recorded the highest value for protein i.e. 20.6033± 0.8113.XSperformed better in terms of crude fat and energy value of 12.2967± 0.8914 and 371.5367 respectively. The use of cocoyam - wheat flour mixture in producing composite bread is therefore strongly recommended from this study.

In this study, carried out at Makurdi Nigeria, peanuts and avocado pulp were processed into flours and blended with refined wheat flour in proportions 100:0:0, 95:5:0, 90:5:5, 85:10:5, 80:10:10 and 75:15:10. The functional properties of the flour blends were determined. Cookies were made using the creaming method from these flour blends with one hundred per cent wheat flour serving as control. The physico-chemical and sensory properties of cookies from wheat/defatted peanut/avocado flour were determined using standard analytical methods. The functional properties of the flour blends increased with increasing substitution of wheat flour with defatted peanut flour and avocado flour. The enriched cookies were found to have higher protein, energy, vitamin and mineral content as compared to refined wheat cookies. The protein content increased from 15% in the control sample to 26.64% in the sample F which is the sample with the highest substitution of wheat flour. Magnesium content increased from 173.37 mg/100 g in the control sample to 221.36 mg/100 g in sample F. There was no significant difference in the dietary fibre content of the enriched cookies as compared to the control. Substitution with peanut flour and avocado flour did not alter the physical properties of the cookies. The sensory scores for all the cookies enriched with defatted peanuts flour and avocado flour were above average 4.5. Sample C, with 5% peanut flour and 5% avocado flour had the best sensory attributes among the supplemented cookies at 5% level of significance and compared favourably with the control cookies. Thus cookies made from wheat, defatted peanut and avocado composite flour at an optimal substitution level of 90;5;5 can be regarded as a suitable balanced meal.
