“…Consumers from western Kenya have a lower preference for white maize, while those from central Kenya a stronger preference for biofortified yellow maize . The survey results also reveal that biofortified b-carotene-enriched maize and OFSP in Mozambique and cassava in northeast Brazil is acceptable to many consumers in these countries (Low et al 2007;Stevens and Winter-Nelson 2008;Gonzalez et al 2009). The yellow gari (made from biofortified cassava containing high b-carotene) in Nigeria is fetching a higher price than white gari (HPlus Nigeria Project).…”

“…This study also revealed the lack of seed availability as one of the main factors limiting the adoption process and thus, suggested strengthening seed production and distribution for better diffusion of the newly developed cultivars among the producers (Gonzalez et al 2011). Preliminary studies in Kenya, Mozambique, and South Africa have shown that provitamin A biofortified maize (grain color orange yellow because of b-carotene) may be adopted where white-seeded maize is the predominant staple crop (Wolson 2007;Stevens and Winter-Nelson 2008).…”

“…It is, therefore, worth investigating the social and economic impacts of nutritionally enhanced transgenic plants such as the cost-effectiveness of adapting local cultivars, social acceptance of the strategy, willingness to pay for genetically modified food Stevens and Winter-Nelson 2008;Gonzalez et al 2009), and the overarching regulatory policy (see Section VII.C) for producing such crops on an agronomic scale (Ramessar et al 2008). The proof of concept of developing nutritionally enhanced biofortified crops through genetic engineering have been demonstrated in maize and rice (see Section VII.A).…”

“…With respect to Golden Rice, the visible differences between this GM biofortified rice crop and its regular counterpart could be a constraint to consumer acceptance, because its yellow color may be linked with a longer shelf life and, thus, lower quality. Similarly, orange, pro-vitamin A biofortified maize is less preferred than unfortified white maize 129,130 .…”

“…The aroma and taste of (conventional) pro-vitamin A enriched maize, for example, was negatively evaluated in Mozambique 130 . Other negative product attribute changes that might be associated with GM biofortification of rice, such as shelf life, duration and sensory quality of cooking, could also play a role and need to be further investigated 129 .…”

SummaryMicronutrient malnutrition, characterized by insufficient intake levels of vitamins and minerals, is a major public health problem that affects about 2 billion people worldwide. In order to reduce the burden of this 'hidden hunger', biofortification is more and more advocated as an alternative to the current micronutrient interventions. Through the enhancement of the micronutrient level of staple crops, it could address micronutrient malnutrition where the need is highest. Because staple crops are characterized by low micronutrient concentrations, genetic breeding techniques are often applied to increase specific vitamin levels, such as folate and pro-vitamin A. This study sheds a light on the global status of micronutrient malnutrition, biofortification and GM biofortified rice as both a GM food product with health benefits and a micronutrient intervention. Thereby, key consumer preference studies and cost-effectiveness analyses on Folate Biofortified Rice and Golden Rice are presented. Support is found for GM biofortified rice as a well-accepted GM food crop and a highly cost-effective health intervention.

We examined whether folate‐fortified maize (FFM) improves the health of rural women of childbearing age and whether the health intervention is associated with the consumer willingness‐to‐pay (WTP) for FFM. First, a randomized single‐blind FFM intervention trial was conducted in rural childbearing‐aged women. Participants (n = 55) consumed one stalk of either FFM (treatment group) or ordinary maize (control group) daily. This dietary intervention lasted for 2 months, during which we assessed the participants' serum folate levels at baseline, mid stage (after 1 month), and final stage (after 2 months) to evaluate the health effect of FFM. We found that the serum folate level in the treatment group (13.31 ng/mL) was 3.40 ng/mL higher than that in the control group (9.91 ng/mL) in the final stage of the study. These findings suggest that regular dietary FFM intake significantly increased serum folate levels in rural Chinese women. Second, we further expanded our study by involving 181 local rural women with similar demographic characteristics to participate in a Becker–DeGroot–Marschak (BDM) bidding experiment to measure their WTPs for FFM. Results showed that local consumers were willing to pay 2.82 Chinese Yuan (CNY) per stalk of FFM, approximately 1.21 CNY higher than the price of ordinary maize. And women who participated in and completed the intervention trial had a higher preference for FFM during the evaluation. We provide evidence on the health improvement effect of biofortified foods and shed light on the associated consumer valuation and policy implementation.
