Orange-fleshed sweet potato (OFSP) is bio-fortified with vitamin A precursors through breeding and is thus ideal for combating vitamin A deficiency (VAD). One of the potential mechanisms to promote the consumption of OFSP is to enhance its availability through processing into products with a longer shelf life and more desirable to consumers. However, very few farmers and agro-processors practice value addition due to market uncertainties; there is little information on market availability for OFSP products. This study examined consumers' preference for OFSP puree chapati in rural and urban areas of Kenya, using the contingent valuation method. Data was collected from a random sample of 411 sweet potato consumers and a double-bounded logit model was applied to analyze consumers' willingness to pay (WTP) for OFSP puree chapati.
Consumers were willing to pay a price of Kenya shillings (KES) 19 (USD 0.14) and 35 (USD 0.26) for OFSP puree chapati in Homa Bay and Nairobi counties, respectively. The presence of children under 5 years in a household, consumers' awareness of OFSP products and benefits of consuming OFSP, and level of education had a positive and significant influence on WTP for OFSP puree chapati in both regions.
The study demonstrated that consumers exhibited a positive preference for OFSP puree chapati. In order to increase the consumption of OFSP and its value-added products, it is important to promote consumer awareness of OFSP puree chapati and other such nutritious products through cooking demonstrations and other nudging approaches using attractive illustrations and social media platforms that engage mothers and care-givers of children under 5 years old as well as the youth. © 2023 The Authors.

通过培育,橙色果肉甘薯(OFSP)富含维生素 A 前体,因此非常适合防治维生素 A 缺乏症(VAD)。促进 OFSP 消费的一种潜在机制是通过加工成保质期更长且更受消费者欢迎的产品来增加其供应。然而,由于市场不确定性,很少有农民和农产品加工商进行增值加工;关于 OFSP 产品的市场供应情况,信息很少。本研究使用条件价值评估法,考察了肯尼亚农村和城市地区消费者对 OFSP 泥糊状薄饼的偏好。从随机抽取的 411 名甘薯消费者中收集数据,并应用双边界对数模型分析消费者对 OFSP 泥糊状薄饼的支付意愿(WTP)。
消费者愿意分别为霍马贝和内罗毕县的 OFSP 泥糊状薄饼支付肯尼亚先令(KES)19(0.14 美元)和 35(0.26 美元)的价格。家中有 5 岁以下儿童、消费者对 OFSP 产品的认识及其食用益处,以及教育程度对两个地区的 WTP 都有积极和显著的影响。
本研究表明,消费者对 OFSP 泥糊状薄饼表现出积极的偏好。为了增加 OFSP 及其增值产品的消费,通过烹饪示范和其他吸引力插图和社交媒体平台,以吸引 5 岁以下儿童的母亲和照顾者以及年轻人为目标,推广消费者对 OFSP 泥糊状薄饼和其他此类营养产品的认识非常重要。© 2023 作者。John Wiley & Sons Ltd 代表化学工业协会出版的《食品科学杂志》。
