Cassava Varieties

Substitution of wheat flour with high quality cassava flour (HQCF) in bread making is economically important in Nigeria as wheat is mainly imported. Different treatments are applied to cassava used for HQCF production and the effects of such a treatment on cassava-wheat bread quality is scarce in literature. This study was conducted to study the effects of cassava varieties (TME 419, TMS 30572), fertilizer type ((NPK 15-15-15, 20-10-10, 12-12-17) and dosage (150, 300 kg/ha) on physical and sensory characteristics of cassava-wheat composite bread according to General Linear Model (GLM) analysis. According to the results, the independent variables had varying effects on the composite bread quality. While the main effect of fertilizer type was significant for oven spring and crumb moisture content, the interactive effects of fertilizer type and dosage significantly influenced crumb texture and taste. In spite of the significant differences in certain physical and sensory attributes, the overall acceptability of bread samples did not differ significantly. HQCF from cassava variety TMS 30572 showed the best performance in making composite cassava-wheat bread in terms of physical and sensory properties.

Replacement of wheat flour by other kinds of flour in bread making is economically important in South East Africa as wheat is mainly an imported commodity. Cassava is widely available in the region, but bread quality is impaired when large amounts of cassava are used in the bread formulation. Effect of differently processed cassavas (sun-dried, roasted and fermented) on composite cassava-wheat-maize bread quality containing cassava levels from 20 to 40% (w/w) was evaluated in combination with high-methylated pectin (HM-pectin) added at levels of 1 to 3% (w/w) according to a full factorial design. Addition of pectin to cassava flour made it possible to bake bread with acceptable bread quality even at concentration as high as 40%. In addition to cassava concentration, the type of cassava flour had the biggest effect on bread quality. With high level of cassava, bread with roasted cassava had a higher volume compared with sun-dried and fermented. The pectin level had a significant effect on improving the volume in high level roasted cassava bread. Crumb firmness similar to wheat bread could be obtained with sun-dried and roasted cassava flours. Roasted cassava bread was the only bread with crust colour similar to wheat bread.

The aim of this investigation was to incorporate tomato seed into bread in order to improve it quality. Whole ground tomato seed at different levels (0, 5, 10, 15 and 20%) was used to replace wheat flour 650 type of a very good quality for bread making to make bread. Bread quality through physical, colour, crumb cell, textural and sensory characteristics were analyzed and compared with those of bread without tomato seed. The substitution of wheat flour with 10% tomato seed has the effect of highest values for loaf volume, porosity and elasticity. Color intensity, expressed as the L*, a*, b* values of breads with tomato seed were lower than those of control bread. The hardness of bread samples increased with the increase level of tomato seed addition. Also, the addition of increasing amounts of tomato seed highlighted large cells in crumb structure of bread. Sensory characteristics showed that bread samples with addition of 5 or 10% tomato seed to wheat flour were similar from of point of view of overall acceptability, but 20% addition resulted in slightly acceptable samples. Principal Component Analysis revealed significant correlations (p < 0.05) between bread physical characteristics, loaf volume, porosity, elasticity and bread overall acceptability at different tomato seed flour addition levels in wheat flour. Overall, tomato seed flour could be incorporated up to levels of 10% into bread to provide its beneficial health effects, not negatively changing its quality.

Purpose – The purpose of this paper is to evaluate some common bread improvers (normally used for 100 per cent wheat bread) for their effect on the quality attributes of wheat-cassava (90:10) composite bread. Design/methodology/approach – Four commonly used bread improvers (ASA, ABT, EDC and PTB) in Nigeria were evaluated for their effect on the baking potential of wheat-cassava (90:10) composite flour. Bread samples were baked from wheat-cassava (90:10) composite flour, with and without bread improvers. Changes in dough height during fermentation, oven spring, yield and specific volume of bread samples were determined. Bread samples were also evaluated for their sensory and staling characteristics. Findings – Results showed that dough height during fermentation did not change significantly (p<0.05) and crumb colour, firmness, taste and aroma were unaffected by addition of bread improvers; but oven spring, yield, specific volume, bread shape, crust colour, texture and overall acceptability of bread were significantly different (p>0.05). All the bread improvers except ABT extended the shelf life of wheat-cassava (90:10) composite bread for a period of 24-48 hours. Practical implications – Bread improvers normally used for 100 per cent wheat bread could be used effectively for wheat-cassava (90:10) composite bread without an adverse effect on quality of bread. Originality/value – Bread makers need little or no additional training to handle wheat-cassava (90:10) composite flour for bread making process hence, Nigeria can sustain her policy of using wheat-cassava composite flour for baking without any serious technical problem.

The aim of this investigation was to incorporate mustard flour into bread in order to improve its quality. For this purpose, wheat flour 650 type for bread making was replaced with mustard seed flour at the level of 5, 7 and 10%. Bread quality through physico-chemical and sensory characteristics was analyzed and compared to those of bread without mustard flour. The protein content of mustard flour bread increased with 5.03% as a result of mustard flour incorporation, coupled with an increase in ash content. Sensory evaluation results revealed that the sample containing 7% mustard flour scored highest in most of the attributes including overall acceptability. The study reveals that incorporation of 7% mustard flour gave desirable results in terms of phisyco-chemical and sensory caracteristics of mustard flour fortified bread.

The optimisation of bread-making process can have a positive impact in ramping up the quality characteristics of cassava-wheat bread to  that of whole wheat bread. In this study, a threevariable Box-Behnken design response surface methodology was employed to investigate and optimise independent variables namely cassava flour composition, water content and proofing time in relation to response variables namely dough yield, loaf specific volume and loaf protein of cassava-wheat-composite bread. The data from the experimental design were fitted into second-order regression models and their validity and reliability were confirmed by analysis of variance. Optimal cassava flour composition, water content and proofing time were derived as; 100 g/kg, 589 g/kg and 90 min, respectively. It was revealed that cassava flour composition had the most effect on the quality characteristics of cassava-wheat-composite bread. At constant cassava flour  composition, increase in water content and proofing time had a positive effect on all the studied quality characteristics of cassava-wheat composite bread. Increase cassava flour composition regardless of proofing time and water content had a negative effect on loaf specific volume and protein. This study has provided bread-making conditions which can be utilised in enhancing the consumer acceptability of cassava-wheat composite bread.

The aim of this work was to investigate the effect of date seed water-soluble polysaccharides (DSP) and hemicellulose (DSH) as dietary fiber sources in enhancing the wheat bread’s quality. DSP and DSH were extracted from the three date seed varieties Deglet Nour, Ghars Souf, and Allig. The extraction yields ranged from 3.8% to 6.14% and from 13.29% to 18.8%, for DSP and DSH, respectively. DSP and DSH showed interesting functional properties and were incorporated at 0.5% and 0.75% (w/w) in wheat flour with low bread-making quality (FLBM). The results showed that the addition of 0.75% DSH significantly improved the alveograph profile of the dough, and in a more efficient way than that of DSP. Furthermore, bread evaluation revealed that the addition of DSH considerably improved the volume (by 24.22%) and the texture profile of bread (decrease of the hardness and chewiness by 41.54% and 33.81%, respectively), compared to control bread (prepared with FLBM). A sensory analysis showed that the better overall acceptability was found for bread supplemented with DSH. Results in this work demonstrate that hemicellulose fraction extracted from date seeds (DSH) and added with a level of 0.75% to FLBM represents the component that improved bread quality the best.

This study was carried out to investigate proximate composition, bread characteristics and sensory evaluation of cocoyam-wheat composite breads at different levels of cocoyam flour substitution for human consumption.A whole wheat bread (WWB) and cocoyam-composite breads (CCB1,CCB 2 and CCB 3) were prepared in triplicate at 0, 10, 20 and 30% levels of cocoyam flours substitution respectively and assessed for proximatecomposition, bread characteristics and sensory attributes.The results indicate that carbohydrate, crude fiber, and ash contents of the cocoyam-composite breads increased significantly (p<0.05) while the moisture and protein contents decreased significantly with progressive increase in the cocoyam flour substitution. The significant (p<0.05) highest ash, fibre and carbohydrate values of 1.61, 1.54 and 70.40 g/100g dm respectively were observed in 30% cocoyam-wheat composite bread compared to lowest values of1.15, 0.29 and 63.25 g/100g dm, respectively in 100% wheat bread. The significant (p<0.05) higher moisture and protein values of 20.99 and 12.54 g/100g dm were observed in 100% wheat bread compared to lowest values of 17.31 and 9.04 g/100g dm, respectively in 30% cocoyam-wheat composite bread. Bread characteristics showed that, the loaf weight of cocoyam composite breads increased significantly (p<0.05) while loaf volume and specific loaf volume decreased significantly (p<0.05) with increasing cocoyam flour substitution The significant (p<0.05) highest loaf weight of 229.33 g was observed in 30% cocoyam-wheat composite bread compared to 208.33, 221.67 and 225 g observed in 100% wheat bread, 10 and 20% cocoyam-wheat composite breads respectively. The highest loaf volume and specific loaf volume of 800 and 3.49 cc were observed in 100% wheat bread compared lowest values of 580 and 2.78 cc respectively observed in 30% cocoyam-wheat composite bread. The sensory evaluation showed no significant (p>0.05) differences in sensory attributes of taste, aroma and acceptability between the 100% wheat and 10% cocoyam-wheat composite breads (p<0.05). In conclusion, this study has shown that the use of cocoyam flour in bread making is feasible and that incorporation of up to 10% of the flour into wheat flour produced acceptable bread with similar taste and aroma comparable to 100% wheat bread. Nevertheless, it is important to consume this bread with other protein rich diet in order to supplement the reduction resulted from substitution.

Uganda produces cassava, which has potential as a raw material for agro-industry. In this study, wheat flour was blended with high quality cassava flour in the ratios 100:0, 90:10; 80:20; 70:30; 60:40; 50:50 and 40:60 and the composite dough used to prepare bread. The doughs were subjected to rheological analysis using mixolab, consistograph and alveograph. Bread physical properties were measured and sensory qualities evaluated to correlate rheological characteristics of flour/dough with bread quality. Inclusion of cassava flour in the composite dough negatively affected the quality of the composite bread compared to the control. Bread volume (631.0 to 516.7 cm3) decreased, specific volume (2.065 to 1.574 cm3/g) decreased, bread density (0.49 to 0.63 g/cm3) increased. Mean scores for sensory quality parameters reduced: crust colour (6.88 to 4.63), taste (7.13 to 4.25), crumb texture (6.5 to 4.63) and overall acceptability (8.13 to 4.5). Bread quality was positively correlated with mixolab parameters protein weakening (C2), dough stability and dough development time (DDT); alveograph parameters tenacity (P) and deformation energy (W); and consistograph parameter maximum pressure (PrMax). Results showed that bread of acceptable quality can be processed using wheat composite containing 20 % cassava flour. Rheological properties can be used to assess suitability of flour for bread making.
