Perception of Gluten-Free Bread as Influenced by Information and Health and Taste Attitudes of Millennials.

Information on what drives consumers to like or dislike bread is needed to provide insight on developing gluten-free (GF) bread, using indigenous and sustainable crops in Africa, such as sorghum and millet. Consumer attitudes toward the health and taste aspects of food are major drivers of food choices. The objectives of this work were (1) to determine the health and taste attitudes (HTAs) and general perceptions of a group of millennial consumers in South Africa (n = 354), concerning GF breads; and (2) to determine whether HTAs affect the acceptability of sensory properties of commercial GF breads, as assessed by consumers (n = 173), under informed and uninformed conditions. Mean scores of the taste factors were higher compared to health factors, indicating a greater taste orientation. The sensory properties of standard wheat breads were preferred over two commercial GF breads, irrespective of the health/taste interests of consumers, or if they were informed/uninformed about the nature of the bread (GF or wheat). Knowledge that bread samples were GF reduced only the acceptability of the aroma of GF bread. GF bread was perceived as healthier, but less tasty. For this group of millennials, the sensory properties of bread was the main driver of choice.

Towards Sustainable Shifts to Healthy Diets and Food Security in Sub-Saharan Africa with Climate-Resilient Crops in Bread-Type Products: A Food System Analysis.

Massive urbanization and increasing disposable incomes favor a rapid transition in diets and lifestyle in sub-Saharan Africa (SSA). As a result, the SSA population is becoming increasingly vulnerable to the double burden of malnutrition and obesity. This, combined with the increasing pressure to produce sufficient food and provide employment for this growing population together with the threat of climate change-induced declining crop yields, requires urgent sustainable solutions. Can an increase in the cultivation of climate-resilient crops (CRCs) and their utilization to produce attractive, convenient and nutritious bread products contribute to climate change adaptation and healthy and sustainable diets? A food system analysis of the bread food value chain in SSA indicates that replacement of refined, mostly imported, wheat in attractive bread products could (1) improve food and nutrition security, (2) bring about a shift to more nutritionally balanced diets, (3) increase economic inclusiveness and equitable benefits, and (4) improve sustainability and resilience of the food system. The food system analysis also provided systematic insight into the challenges and hurdles that need to be overcome to increase the availability, affordability and uptake of CRCs. Proposed interventions include improving the agronomic yield of CRCs, food product technology, raising consumer awareness and directing policies. Overall, integrated programs involving all stakeholders in the food system are needed.

Quality characterization of wheat, maize and sorghum steamed breads from Lesotho.

BACKGROUND: In Lesotho, traditional bread covers different types of dumplings prepared with cereal flour, water, salt and sourdough. This study characterized eight steamed breads prepared from wheat, maize and sorghum. Breads were prepared from both commercial and self-milled flours according to the procedures followed in rural and urban areas of Lesotho. Descriptive sensory evaluation was conducted to profile sensory properties of the breads. Flour particle sizes, sourdough properties and bread colour, volume and texture were also characterized. RESULTS: The type of cereal and milling properties of the flour used had substantial effects on the physical and sensory properties of the bread. Steamed wheat breads had greater volume, softer crumb and more bland flavour compared with sorghum and maize breads. Both sorghum and maize steamed breads prepared according to traditional Basotho procedures were characterized by low loaf volume, denser crumb, more complex and strong flavours and aroma, notably sour, musty, malty, dairy sour and fermented aroma. The texture of the non-wheat bread types was heavy, chewy, dry, fibrous and more brittle and needed a higher compression force to deform. CONCLUSION: This study provided insight on the sensory properties of steamed bread as prepared in Lesotho. Further research is needed to optimize sensory properties of the non-wheat steamed breads by controlling the flour particle size, compositing non-wheat flours with different levels of wheat flour, addition of protein sources and gums, altering the amount of water, improving the pre-gelatinization process and optimizing the steaming method of cooking bread.
