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.

Composite Bread

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.

Fermentation Parameters

Amaranth flour from germinated (GA) and non-germinated (A) seeds (0%-C, 5%, 15%, 25%) were mixed with wheat flour for breadmaking. Fermentation parameters of dough (time-tf, maximum volume-Vmax) were obtained. Specific volume (Vsp) of breads, crust color, texture and relaxation of crumb were analyzed. A high amount of germinated amaranth flour decreased Vmax and increased tf, obtaining breads with low Vsp and darkness crust. A firmed and chewy crumb, although with a more aerated structure (high area occupied by alveoli) was obtained. The GA25 bread presented the softer crumb. The elastic modulus-E1 of crumb increased and the relaxation time-T1 decreased with higher amounts of amaranth flour, suggesting the formation of a more structured crumb; mainly in the case of non-germinated amaranth flour. Wheat flour resisted the inclusion of 25% of germinated amaranth seeds (GA25) without substantial changes in bread quality.

The objective of this study was to examine the effect of different levels of catfish bone paste to flour on the physicochemical, textural and crumb structure properties of steamed bread. Six different levels (0, 1, 3, 5, 7,10 %) of catfish bone paste to flour were used in the formulation of the steamed bread. The results showed that the weight loss and TTA of steamed bread decreased with an increase in the levels of the catfish bone paste. On the other hand, the pH increased with an increase in the levels of the catfish bone paste. The specific volume, hardness, chewiness and gas cell structure in the crumb of steamed bread with catfish bone paste at 5% supplementation level were better. Thus, a value of 5% catfish bone paste was considered a better level for incorporation into the steamed bread.

Wheat Flours

Vital gluten is often used in baking to supplement weak wheat flours and improve their baking quality. Even with the same recipe, variable final bread volumes are common, because the functionality differs between vital gluten samples also from the same manufacturer. To understand why, the protein composition of ten vital gluten samples was investigated as well as their performance in a microbaking test depending on the water content in the dough. The gluten content and composition as well the content of free thiols and disulfide bonds of the samples were similar and not related to the specific bread volumes obtained using two dough systems, one based on a baking mixture and one based on a weak wheat flour. Variations of water addition showed that an optimal specific volume of 1.74–2.38 mL/g (baking mixture) and 4.25–5.49 mL/g (weak wheat flour) was reached for each vital gluten sample depending on its specific water absorption capacity.
