Consumer acceptance of foods derived from blended wheat flour in Nairobi, Kenya
通过感官评价和条件估值法，研究了肯尼亚内罗毕消费者对混合高粱、小米或木薯粉的小麦粉制成的查帕提和面包的接受度，发现消费者在知情后更偏好混合粉产品并愿意支付更高价格。
• Consumers perceived wheat-based foods derived from blended flour as healthy. • Most consumers accepted chapati made from wheat flour blended upto the 10% level. • Bread derived from blended wheat flour blended above the 5% level was less preferred. • Information on flour composition increased preferences for foods derived from blended wheat flour. • Consumers prefer products derived from blended flour due to perceived health benefits. Governments across Africa have shown enthusiasm for wheat flour blending to reduce food security risks and pull demand for traditional but underutilized crops. However, research has sidestepped the question of whether consumers will accept foods derived from blended wheat flour. We used sensory evaluation and contingent valuation techniques with a sample of 1871 consumers in Nairobi, Kenya to measure the acceptance of two commonly consumed foods (chapati and bread) made from wheat flours blended with up to 20% sorghum, millet, or cassava flour. In blind tasting, bread made of blended flour was slightly less preferred than conventional bread, while chapati products made of wheat and sorghum (10%) or millet (5%) blends were equally valued as chapati made of 100% wheat flour, suggesting the potential to replace up to 10% of wheat flour in chapati without compromising sensory characteristics and consumer acceptance. When informed about the flour composition before tasting, consumers showed a stronger preference for the products made from blended flour and expressed a higher willingness to pay for blend-based products than conventional products. We discuss the policy implications of how consumer interest in such foods can be harnessed to advance food security and economic development goals.
