Maize is the major food staple in East and Southern Africa, where food-processing industries are emerging fast. New low-cost extrusion cookers allow small enterprises to enter the market for processed cereals, including instant, fortified, and flavored products.
Assess consumers' interest and preferences for the new products.
Consumers (n = 220) in Eldoret, Kenya, were invited to evaluate 4 new cereal products: (1) sifted maize flour mixed with sorghum, (2) instant sifted mixed flour, (3) instant whole flour, and (4) instant whole flour fortified with natural ingredients and to compare them to conventional sifted maize flour, using 2 preparations: stiff porridge () and soft porridge (). These were followed by economic experiments to estimate consumers' willingness to pay (WTP) for the new products and traits.
For , consumers preferred conventional sifted maize flour, while for , they appreciated the new products, especially sifted mixed flour (with sorghum) and instant whole mixed flour. Fortification with food-to-food sources was not appreciated, especially for . Comparing WTP for the traits with their production cost showed that mixed, whole, and instant flours were economical, but not fortification. Maize/sorghum mixtures realized a benefit of 24% over conventional maize flour, whole meal 11%, and instant mixtures 5%.
There is a potential market for improved cereal products in Kenya, but more for than for , especially with instant, mixed, and whole flour. Acceptable and affordable products, fortified with other foods that are locally available, however, still need to be developed, especially for .
玉米是东非和南非的主要粮食作物,那里的食品加工产业正在迅速发展。新型低成本挤压蒸煮器使小型企业能够进入加工谷物市场,包括速溶、强化和调味产品。
评估消费者对新产品的兴趣和偏好。
邀请肯尼亚埃尔多雷特的消费者(n=220)评估 4 种新的谷物产品:(1)筛过的玉米粉与高粱混合,(2)速溶筛过的混合面粉,(3)速溶全麦粉,(4)用天然成分强化的速溶全麦粉,并将它们与传统的筛过的玉米粉进行比较,使用 2 种制备方法:稠粥()和软粥()。随后进行经济实验,以估计消费者对新产品和特性的支付意愿(WTP)。
对于稠粥,消费者更喜欢传统的筛过的玉米粉,而对于软粥,他们则更喜欢新的产品,特别是筛过的混合面粉(与高粱混合)和速溶全麦混合面粉。用食物对食物来源强化并不受欢迎,特别是对于稠粥。将 WTP 与生产成本进行比较,结果表明混合、全麦和速溶面粉在经济上是可行的,但强化则不然。玉米/高粱混合物比传统玉米粉的效益高 24%,全麦粉高 11%,速溶混合物高 5%。
肯尼亚有改善谷物产品的潜在市场,但对于软粥的需求高于稠粥,特别是对于速溶、混合和全麦面粉。然而,仍需要开发可接受和负担得起的产品,特别是对于稠粥,强化其他当地可用的食物。
