“…A target level of 15 mg b-carotene equivalents/g dry weight has been set by nutritionists for provitamin A biofortification of maize based on calculations that this would provide the estimated average requirement of vitamin A to children who consume 200 g/d dry maize (44). Although recent studies in Central and South Africa suggest that acceptance is likely (45)(46)(47), the obvious yellow/ orange color of the kernels represents an obstacle for acceptance by consumers accustomed to eating almost exclusively white maize. Food preferences are often modifiable with enough incentive or education.…”

Africa shares a unique relationship with maize (Zea mays). After its introduction from New World explorers, maize was quickly adopted as the cornerstone of local cuisine, especially in sub-Saharan countries. Although maize provides macro-and micronutrients required for humans, it lacks adequate amounts of the essential amino acids lysine and tryptophan. For those consuming >50% of their daily energy from maize, pandemic protein malnutrition may exist. Severe protein and energy malnutrition increases susceptibility to life-threatening diseases such as tuberculosis and gastroenteritis. A nutritionally superior maize cultivar named quality protein maize (QPM) represents nearly one-half century of research dedicated to malnutrition eradication. Compared with traditional maize types, QPM has twice the amount of lysine and tryptophan, as well as protein bioavailability that rivals milk casein. Animal and human studies suggest that substituting QPM for common maize results in improved health. However, QPM's practical contribution to maize-subsisting populations remains unresolved. Herein, total protein and essential amino acid requirements recommended by the WHO and the Institute of Medicine were applied to estimate QPM target intake levels for young children and adults, and these were compared with mean daily maize intakes by African country. The comparisons revealed that w100 g QPM is required for children to maintain adequacy of lysine, the most limiting amino acid, and nearly 500 g is required for adults. This represents a 40% reduction in maize intake relative to common maize to meet protein requirements. The importance of maize in Africa underlines the potential for QPM to assist in closing the protein inadequacy gap. Adv. Nutr. 2: 217-224, 2011.

“…In this case farmers as well as consumers have to decide actively in favor of biofortified crops for the latter to have an impact on mineral malnutrition. Various studies on the acceptance and on potential barriers to the adoption of noticeably biofortified crops have been carried out (Chowdhury et al 2009;Stevens and Winter-Nelson 2008;Muzhingi et al 2008;De Groote and Chege Kimenju 2008;Dickinson et al 2009;Heyd 2007;Wolson 2007;Mazuze 2007;Chong 2003;Hagenimana and Low 2000). These studies indicate that, above all, biofortified crops have to have agronomic properties of interest to farmers (e.g.…”

“…Prices of yellow maize are generally lower than for white maize, as observed in Zambia (Diskin and Kipola, 1994), Mozambique (Tschirley et al, 1996) and South Africa (FAO and CIMMYT, 1997). During surveys, consumers have frequently stated their preference for white maize, as documented in Mozambique (Tschirley and Santos, 1995) and Zimbabwe (Rubey and Lupi, 1997;Muzhingi et al, 2008). In both countries, consumers were willing to switch to yellow maize given a price discount.…”
