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.

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.

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.

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.

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 purpose of this paper is to study and minimize loss of vitamin B₉ in bread during warming protocol.

In this study, warming intensity, warming time, warming device, and bread storage method were selected as the most effective factors on B₉ loss in bread. The variation of B₉ in bread and its loss were studied with orthogonal array design (OAD) using the L₉ optimization matrix.

With a calculated per cent of contribution (P%) of error of 0.38 per cent and according to the analysis of variance, ANOVA, of the fluorescence data, 86 per cent of B₉ was saved by using toaster as the warming device, a bread warming temperature of <200^○F and a warming time of <10min. Fluorescence method evaluated warming intensity and warming device as the most powerful factors affecting the B₉ concentration in bread with corresponding P% of 42.28 per cent and 41.72 per cent, respectively.

In conclusion, heat destroyed significant portion of B₉ in bread during daily warming protocols, and the suggested optimized parameters obtained in this work significantly minimized this loss.

The OAD can be used to effectively evaluate effective parameters on food science investigations.

The purpose of this paper is to describe the attributes and benefits of branded bread as perceived by the consumers.

Previous research on bread is illustrated briefly. The concepts of brand identity and image are introduced, and the brand as a product is presented and subsequently a value proposition is described and used as a theoretical model.

The findings indicate that nine types of attributes and six types of benefits as perceived by the consumers were found. The types of attributes were related to raw materials, taste, manner of baking, characteristics of the bread, outward appearance, quality, origin, package, and comparison with competing breads. The types of benefits were classified as functional, emotional, self‐expressive, and social. Furthermore, two types of price benefits emerged (positive and negative). The targeted brand identity by the bakery and the perceived image of the branded bread by the consumers were compatible. The brand image as perceived by the customers was varied.

The bakery can utilize the findings in its marketing communication, advertising, campaigns, and when planning the assortment. The findings offer valuable information also for the advertising agency when designing the advertising messages and the unique selling propositions for the case bread.

Compared to the existing research on bread, the contribution of the results is that the bread was analysed from the point of view of the attributes and benefits it offers.

Wheat is the staple food in many parts of the world and bread is one of the most important products of wheat flour. There is a need for innovations in bread making to increase its shelf life and consumer's attraction. Fermentation is mostly done by yeast but it does not produce appreciable amounts of organic acids, which are required to enhance the shelf life of bread. The present study aims to determine the effect of bacterial and yeast culture blends on the quality and shelf life of sourdough bread and to observe the sugar utilization during fermentation.

Three treatments were made using different blends of bacterial cultures (homo‐fermentative and hetero‐fermentative) and baker's yeast compared with a control having only baker's yeast. Chemical analysis, sugar utilization (Sucrose, glucose and fructose) through high performance liquid chromatography, sensory characteristics (both internal and external) and microbial count (Bacterial and fungal count) for each treatment were conducted at different storage intervals.

The hetero‐fermentative bacteria i.e. Lactobacillus plantarum along with baker's yeast exhibited the best results regarding the utilization of sugars during fermentation (after 3 h of fermentation 0.0158 mg/ml sugar remained), objective evaluation of bread and its sensory characteristics. The bread prepared using the blend of hetero‐fermentative bacteria (0.5 per cent) and yeast (0.5 per cent) also showed greater resistance against bacteria (9×10¹ cfu/g after 60 h of storage) and mold (1.1 ×  10² cfu/g after 60 h of storage) growth.

Hetero‐fermentative bacteria along with baker's yeast can be utilized in sour dough to improve major bread characteristics. This study is a step further in improving the shelf life of sourdough.

Presently only baker's yeast is being used by bread industry for fermentation purpose but a blend of bacterial culture along with baker's yeast can give better performance for better quality and shelf life of the bread.

Reports a study to determine the suitability of beniseed for bread making as well as the chemical composition and acceptability of the bread among Nigerian bread consuming population. Three bread samples were developed from wheat, beniseed, and cassava composite flour using the formulae 85:10:5, 80:15:5 and 75:25:5. Baking characteristics, chemical composition and acceptability tests were carried out on the samples with wheat bread serving as control. Results show that bread produced from beniseed composite flour has similar baking characteristics in terms of appearance, colour and flavour when compared with wheat bread. Consumer acceptability tests indicated that the bread samples were all acceptable, with the sample with formula 85:10:5 ranked first and being the most preferred. Analysis of chemical composition indicated that the bread samples contain higher protein, fat, crude fibre and ash. This study has shown that acceptable bread of higher nutritional value can be produced from beniseed.

After completion of the case study, students are expected to demonstrate understanding of the process of strategy formulation (which include conducting situational analysis) and strategy implementation.

Perusahaan Azan, which trades under the brand name Roti Azan for its fresh bread and Azan for its dry bread or rusks, was established as a family business in 1968 by Haji Abu Bakar bin Ali in his hometown in Kuala Pilah, in the state of Negeri Sembilan in Malaysia. In the mid-1980s, the management of the business was passed on by Haji Abu Bakar to one of his sons, Haji Mohd Ghazali bin Haji Abu Bakar. Haji Ghazali was named managing director in 1985 and officially inherited his father’s company in 1987. By 2004, Perusahaan Azan breads had started to penetrate major grocery stores nationwide, and later the business began to expand internationally in 2010, with Oman and Iraq among the first countries it ventured into. The company sold both its fresh and dry bread in local stores; however, in the international market, only dry bread types were sold, specifically wholemeal rusks and long rusks, which had longer shelf lives. Post-pandemic, by 2022, the company had exited the retail fresh bread market and had focused only on its contractual fresh bread and retail dry bread markets. He thought about the main strategic choices he had of going forward, either to revive its retail fresh bread segment or venture into a coffee shop business. The former was the bread and butter of the company in the last 50 years. However, he knew that re-entering this market was getting more difficult, as it requires competing head-to-head with the giant breadmakers. There were also issues of rising costs and high wastage. For the latter coffee shop project, the company did not have experience in directly “serving” the customers, with its businesses so far had been mainly in production. He pondered on the best decision to undertake to sustain the company’s profitability into the next generation. Few family businesses can pass this crucial stage. He knew he had to act fast to ensure that the company’s plans for the future could be successfully implemented. The case study is suitable for use in teaching courses in strategic management, organisational management and integrated case study for advanced undergraduates and postgraduates in the programmes of business administration, Muamalat administration and accounting.

The purpose of this current investigation is to evaluate the effect of adding different levels of cheeseweed Malva parviflora L. mallow leaves powder (MPLP) on the nutritional and quality characteristics of bread.

Wheat flour was partially replaced with MPLP at 0%, 1%, 2%, 3%, 4% and 5% levels to obtain the wheat– MPLP composite flour. Chemical composition, phenolics, flavonoids and antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl of wheat flour and MPLP were determined. Physicochemical and sensory characteristics of bread enriched with various levels of MPLP were evaluated.

MPLP contains 23.9% of protein, 10.1% of crude fiber and 9.8% of ash, respectively. MPLP had a significantly higher concentration of micronutrients than wheat flour. The content of total phenolics, flavonoids as well as free radical scavenging activity of MPLP were 17.6, 38.2 and 6.0 fold, respectively, higher compared to wheat flour. Protein content in bread samples increased with the addition of the MPLP in a range of 1.2%–6.6%. The increasing replacement of MPLP in the composite flours resulted in progressively higher dietary fiber and ash contents for fortified bread samples. The higher level of MPLP reduced the specific volume of fortified breads. The highest scores for the sensory attributes were noted for bread samples fortified with 2% and 3% of MPLP, whereas the lowest scores for bread samples fortified with 4% and 5% MPLP.

Supplementation of wheat bread with different levels of MPLP resulted in significant increases in macro and microelements of fortified breads.

Supplementation of wheat bread with different levels of cheeseweed Mallow (Malva parviflora L.) leaves powder resulted in significant increases in macro and microelements of fortified breads.

The purpose of this paper is to investigate the effect of partial substitution of wheat flour with sweet potato flour on the nutrient composition and sensory properties of bread.

Sweet potato flour was blended with wheat flour at 5, 10, 15, 20 and 25 percent levels of substitution for bread production. Proximate, minerals and antinutritional factors of the breads were investigated using AOAC methods. Sensory evaluation was carried out by a panel of 50 consumers. Data were subjected to analysis of variance and means were separated by Tukey’s comparison test at p <0.05. Results were reported as mean ± SD.

The nutritional and sensory quality of bread made from wheat flour supplemented with sweet potato flour at 5, 10, 15, 20 and 25 percent was investigated. Blending of sweet potato flour with wheat flour had significantly decreased the protein content (4.76–7.78 percent) while the ash (1.35–3.07 percent), crude fiber (0.24–1.03), carbohydrate contents (88.39–90.45 percent), iron, zinc, phosphorus and vitamin A contents were significantly increased ( p<0.05) with increasing sweet potato flour in the formulations. The tannin and phytate contents of the composite breads were low. Sensory evaluation of the breads revealed a mild reduction of the bread’s general acceptability with increase in the substitution level by sweet potato flour.

This study showed that the wheat flour used in making breads could be substituted with up to 15 percent sweet potato flour without compromising its nutritional quality, with only a mild reduction in sensory quality.

Soaked–dehulled moth bean seed (SDMBS) powder was incorporated into wheat flour and the paper aims to investigate its effects on the nutritional and quality properties of composite bread.

Different ratios of SDMBS powder (0%–12.5%) were mixed into wheat flour to prepare composite bread. Proximate composition, mineral content and functional properties of SDMBS powder and wheat flour were studied. The composite bread samples were assayed for proximate composition, mineral nutrients, amino acid composition, physical characteristics as well as sensorial properties.

Protein and ash contents of SDMBS powder were found to be 2.15 and 5.69 fold higher than wheat flour. Water absorption capacity (WAC), oil absorption capacity (OAC), (FC) and emulsion activity (EA) values of SDMBS powder were also 1.63, 1.78, 4.43 and 1.58 times higher than wheat flour, respectively. The inclusion of different levels of SDMBS powder into wheat flour significantly (p = 0.05) increased the functional properties of composite flours. Bread samples fortified with SDMBS powder exhibited higher values of essential amino acids than the recommendations of World Health Organization/Food and Agriculture Organization/United Nations University (2007). The bread samples containing 10% and 12.5% of SDMBS powder provided 39.23% and 41.15% of the recommended lysine level, respectively. The addition of a higher proportion of SDMBS powder into wheat flour gradually increased the protein and ash contents of the bread samples. Control sample without SDMBS powder (0%) and samples fortified containing 2.5% and 5% of SDMBS powder received the highest scores of overall acceptance, whereas the bread sample with the highest SDMBS powder (12.5%) content received the lowest scores.

The main findings of the current investigation indicated that the addition of 2.5–5% of SDMBS powder into wheat flour enhanced the nutritional and quality characteristics of wheat bread.

SDMBS powder could be incorporated into refined wheat bread to achieve functional bread with significantly higher protein content.

The preparation of gluten-free bread is a challenge because the gluten in wheat is the main ingredient responsible for the retention of the gases which cause the bread to rise. This paper aims to develop breads without gluten and fat, and to evaluate the effect of the use of chia (Salvia hispanic L.) flour on the physical, nutritional and sensory properties of the breads that were developed.

Three formulations were developed with different proportions of chia flour (2.5, 5 and 7.5%), fat-free. Physiochemical, sensorial analyses were performed out in three repetitions (p-value = 0.05).

In the nutritional assessment, the results demonstrated that 7.5% chia showed higher levels of protein (15.1%), lipid (3.43%), total fiber (7.04%) and lower levels of carbohydrates (22.49%), with significant nutrient enrichment (p-value = 0.05). The specific volume and the elevation of the dough decreased with the addition of chia flour. In the sensorial analysis, the treatments with chia flour showed no significant difference regarding flavor and texture when compared to the standard. The addition of chia improved the nutritional and sensory properties (p-value = 0.05).

The chia flour improved the nutritional characteristics of the breads, in the reduction of carbohydrate content and the increase in the content of protein, minerals and fiber. It presented good acceptability and good nutritional characteristics, providing a healthy and differentiated variation in this segment.
