Consumer acceptance of quality protein maize (QPM) in East Africa

Abstract

Background: Undernutrition in sub-Saharan Africa remains problematic, and quality protein

Measuring consumers' interest in instant fortified pearl millet products: a field experiment in Touba, Senegal

“…The experience of this study showed how BDM, which is conducted individually, was easy to use with respondents with little or no education, and particularly suited for rural dispersed populations. It was therefore selected to estimate WTP for quality protein maize, in combination with both central locations affective tests and modified home use tests, with adults and with both mothers and children, with all experiments including an information component.…”

“…If the respondents are randomly selected, the standard procedure assumes that u i is randomly distributed; it is also called the random effects model. Such models have been used to analyse farmer participatory evaluation of new technologies and consumer evaluation of maize products …”

“…Before bringing improved cereal food products to the market in low‐income countries, it is important to evaluate consumer acceptance of these products. In Africa, HarvestPlus (a program to reduce malnutrition through biofortification of staple food crops) has been conducting consumer acceptance studies for biofortified crops such as orange‐fleshed sweet potatoes, while the International Maize and Wheat Improvement Centre (CIMMYT) conducted similar studies with Quality Protein Maize (QPM) in East Africa . HarvestPlus organised the first combination of sensory evaluation with economic experiments, in particular choice experiments, with provitamin A biofortified (proVA) maize and orange‐fleshed sweet potatoes .…”

Quality attributes of homemade tomato sauce stored at different temperatures

“…The widely used 5-point hedonic scale for evaluating sensory characteristics such as color, taste, flavor and texture was used (De Groote et al, 2014). Panelists were asked to evaluate tomato sauce at each testing time session on the 5 point scale (5 = Like extremely; 4 = Like very much; 3 = Like moderately; 2 = Neither like nor dislike; 1 = Dislike).…”
