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.

Application of wheat flour in various food products has increased the import of wheat flour over years. The use of domestically grown crops like Sorghum (Sorghum bicolor L. Moench) could reduce the demand of wheat. Sorghum flour can be used in partial substitution with wheat flour for many food products, like cookies. The use of sorghum as cookies ingredient could be combined with other flours to get a composite flour. The purpose of this research was to obtain proportion of sorghum flour, sweet potato flour and soyabean flour that produce cookies with good organoleptic characteristics. The proportion of composite flour adequacy was calculated using a list of foodstuffs (DKBM).The research method was based on Experimental Method with Randomized Block Design (RBD) in twelve treatments and two repetitions. The treatments were proportion of sorghum flour (6 minutes, 8 minutes, 10 minutes of dehulling time), sweet potato flour, and soyabean flour. The results showed that cookies made with proportion of sorghum flour, sweet potato flour, and soyabean flour gave no significant difference in organoleptic characteristics (Overall, color, taste, aroma, and hardness).  The result also showed that the characteristics of the cookies were not affected by dehulling of sorghum grains but influenced by other ingredient than flour. Keywords: Sorghum, Sweet Potato Flour,  Soyabean Flour, Cookies, Sensory Properties

The quality characteristics and consumer acceptance of wheat-rice composite flour bread were evaluated. Substitution of rice flour was done in wheat flour from 0 to 100% and the composite flour was used to produce bread. The bread samples were subjected to proximate, physical, and sensory analyses. The results showed significant differences (p ≤ 0.05) between the proximate compositions of bread samples studied. Bread from control (100% wheat flour) had moisture content of 28.61±0.28%. Bread from 10-50% wheat-rice composite flour had moisture contents ranged from 28.04±0.41 - 24.81±0.40%. The oven spring of the samples from control (100% wheat flour) had the highest value of 1.12±0.28 cm. The oven spring of wheat-rice composite bread ranged between 1.00±0.22 and 0.82±0.38 cm. There was inverse relationship between loaf weight (g), loaf volume and specific volume and the quantities of rice flour added to the wheat flour. The results of consumer acceptance showed that bread with 70:30 wheat: rice flour ratio was acceptable to the consumers. In conclusion, bread of good quality and good consumer acceptance could be made from wheat-rice composite flour.

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.

This study analyzes the nutritional and sensory properties of wheat- and unripe plantain composite flour having a mix ratio of 70:30, 80:20, 90:10 and 100:0 respectively, with 100:0 ratio mix serving as the control. Unripe plantain flour was selected due to its high iron content which can solve dietary concerns encountered by anaemic and celiac patients because of low iron and high protein (gluten) content in wheat bread. The nutritional analysis of the composite flour such as ash, lipid, fibre, carbohydrate, protein, moisture content and iron contents of the mixed flour were determined. Physical properties of the composite bread were determined: loaf weight, loaf volume, loaf height, and loaf specific volume.The incorporation of plantain flour into baking bread became effective because it is economical, better supplies essential nutrients such as iron and protein to humans, and a better overall use of domestic agricultural products such as plantain.Incorporation of higher amount of unripe plantain flour increased loaf weight with a corresponding reduction in specific volume of the bread, which affected the bread making process. It was concluded that organoleptically acceptable bread could be formulated from wheat-unripe plantain composite flours using up to 70:30 mix ratio as maximum acceptable levels of substitution for bread making

Bread is popular around the world and is one of the world’s oldest foods. Bread is usually made from common wheat-flour dough. Till date most people are not familiar with other types of bread apart from that made from 100% wheat flour. When a part of wheat flour is replaced with flours from other food sources (yam, cassava, etc) the wheat gluten is automatically reduced. This study aimed at re-examining the approval of ten percent (10%) cassava flour inclusion in bread baking in Nigeria and evaluating higher % substitutions, with a view to increasing cassava carrying capacity for producing acceptable bread. The water absorption capacity (WAC) of wheat, cassava and composite flours ranged from 62.7 to 79% while oil absorption capacity (OAC) ranged from 4.5 to 72%. As cassava percent inclusion increased both WAC and OAC increased. Bread loaves produced from 10-20% inclusions without egg white had sensory scores of 3.2 to 3.9 and were significantly (p &lt; 0.05) better than 25-30% wheat cassava composite bread loaves. In all sensory attributes, 10-20% cassava inclusion, with added egg white, produced bread loaves which were as good as 100% wheat bread. In terms of taste, colour, odour and texture 25-30% composite bread loaves had identical sensory values. This study showed that bread of acceptable quality can be produced from wheat flour substituted with up to 30% cassava flour.

Cassava (Manihot esculenta Crantz) and cowpea (Vigna unguiculata L. Walp) were processed into flours and used to substitute wheat flour for preparation of cookies. The chemical, including proximate composition and anti-nutritional factors, and functional and pasting properties of the blends were determined. Cookies were produced from the blends with 100% wheat flour as a control. The anti-nutritional factors, physical properties and organoleptic attributes of the cookies were evaluated. An increase in the level of cassava flour substitution resulted in a decrease in the protein content of the composite flour. However, addition of cowpea flour resulted in an increase in the protein content. There were significant (p<0.05) reductions in the studied anti-nutritional factors after baking. Cookies from composite flours were not significantly (p>0.05) different from the control in overall acceptability. This indicates the feasibility of producing nutritious cookies with desirable organoleptic qualities from cassava, wheat and cowpea composite flour.

Introduction: There is complete dependence on wheat flour for baked products, which are imported from other parts as wheat can’t grow in Nigeria. Therefore, to reduce the cost of importation, composite flour can be an alternative. Composite flour has some advantages for developing countries such as Nigeria as it reduces the importation of wheat flour and encourages the use of locally available resource for making flour. Methodology: Orange -fleshed sweet potatoes (OFSP), yellow roots cassava (YRC) were all sourced from National Root Crops Research Institute Umudike (NRCRI), while the plantain and Moringa oleifera leaves were gotten from Umuahia market and Michael Okpara University of Agriculture Umudike (MOUAU) respectively. The samples were processed into flour to form different blend ratio. The flour blend constitutes of yellow root cassava, orange fleshed sweet potato and plantain which were fortified with Moringa oleifera leaves at constant portion of 5% while the YRC, OFSP and plantain were varied at different concentrations. Three (3) experiments were conducted, of which experiment 1 is the flour made from the blend of YRC, OFSP, plantain and moringa oleifera leave. Sample A, B, C, D, E F, G and H were the composite flour. A consist of  65% YRC, 10% OFSP, 20% Plantain, 5% moringa leaves powder: B consist of 70% YRC, 10% OFSP, 15% Plantain, 5% moringa leaves powder: C is 75% YRC, 10% OFSP, 10% Plantain, 5% moringa leaves powder, D is made up of  80% YRC, 5% OFSP, 10% Plantain, 5% moringa leaves powder, E is  85% YRC, 5% OFSP, 5% Plantain, 5% moringa leaves powder, F is 95% and 5% moringa leaves powder, G is 95% plantain and 5% moringa leaves powder and H is 95% and 5% moringa leaves powder respectively. Experiment 2 was the extruded baked snacks from the blend ratio of composite flour and Experiment 3 was the fresh of yellow root cassava, plantain and orange fleshed sweet potatoes analysed on fresh basis. Results: The breakdown of the extruded baked snacks ranged between (254.72 RVU to 298.54 RVU) from sample P to J. No significant difference (P >0.05) was observed among samples K (271.64 RVU), N (276.64 RVU) and M (279.11 RVU). Peak viscosity values obtained from experiment 1 ranged from 202.31 RVU to 388.68 RVU. There was no significant difference (P >0.05) among the samples A (382.65 RVU), D (382.07 RVU), E (383.07 RVU) and H (384.63 RVU).The holding strength of the composite flour in this study range from 123.16 RVU to 256.62 RVU. The result on experiment 3i. e. fresh of yellow root cassava had the highest peak viscosity of (355.72 RVU), followed by sample R (291.75) and sample S (260.09 RVU) which were the fresh plantain and fresh orange-fleshed sweet potato. Result of trough, indicated that sample Q (117.17 RVU) had the highest trough followed by sample R (83.40 RVU) and S (80.16 RVU). A significant difference was observed on final viscosity within the fresh samples whereby sample Q (394.09 RVU) had the highest score followed by sample R (334.13 RVU) and S (300.63 RVU). Conclusion: There was no significant difference (P >0.05) within experiment 1, 2 and 3 on peak value, final viscosity, setback, breakdown and peak time while the trough was high in experiment 1 (composite flour) than in experiment 2 and 3. As food, the extrudates with low relative viscosity can easily be eaten by infants while those with high viscosity can only be eaten easily by adults because they tend to be hard and cohesive in texture than samples with low viscosities.

Flour quality is influenced by the nature of the gluten and its various components. Gluten free flour made of pulses is known to enhance the nutritional quality of wheat flour. However, its addition can compromise the rheological and sensorial attributes of the bread. We used mixture design to optimize nutritional and technological qualities of a wheat–chickpea flour blend by adding milk powder as a natural organoleptic improver. A total of thirteen flour blends were prepared by incorporating 10 to 30% chickpea flour and 10 to 20% milk powder to wheat flour. Our results showed that the optimal flour blend consisted of 60% wheat, 24% chickpea, and 16% milk powder. Farinographic parameters of the optimal dough blend remained on par with those of the control dough (100% wheat flour), thereby preserving its bread-making quality. Sensory analysis of breads made from the optimal flour blend revealed no significant difference (p ≤ 0.05) from wheat flour for crumb and chewiness. Appreciation was brought to the appearance, crust, aroma, and taste in the optimized bread. This study suggests that chickpea flour can be suitably incorporated into bread wheat flour up to a percentage of 24% with 16% milk powder to produce bread with optimal nutritional quality while improving its sensory attributes and consumer acceptability.

The influence of secondary apple raw materials (frozen apple pomace) on organoleptic and physicochemical indicators of the quality of wheat bread has been studied. The traditional recipe of wheat bread was taken as a basis. In this recipe for the sample of bread No. 1, a part of the premium wheat flour was replaced with 25% rice flour and 10% frozen apple pomace. In the sample of bread No. 2, a part of the premium wheat flour was replaced with 12.5% rice flour and 10% fresh frozen apple pomace. For the organoleptic assessment, a five-point scale for assessing the quality of bread was developed, in which the maximum number of points up to5 was assigned to each indicator. According to the results of the study of the organoleptic indicators of the quality of the developed samples of bread using a point scale, it was found that they exceeded the control sample. The best was the sample with fresh frozen apple pomace10% and rice flour in the amount of 12.5%. In terms of physical and chemical indicators, the developed samples of wheat bread enriched with apple raw materials meet the regulatory requirements.

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.
