Consumer acceptance of quality protein maize (QPM) in East Africa
Under nutrition in sub-Saharan Africa remains
problematic, and quality protein maize (QPM) can benefit populations whose
diets are heavily based on maize and who are consequently at risk for
inadequate intakes of quality protein. However, changes in the chemical
composition of QPM may affect its sensory characteristics and, hence,
acceptance. Acceptance tests were therefore conducted to evaluate QPM varieties
in three East African countries using central location tests with one or two
varieties in each country, using the most popular preparations: ugali
(Tanzania), githeri (Kenya) and injera (Ethiopia). In total, 281 urban and
rural consumers of both sexes and varying levels of education evaluated the
products on standard sensory criteria: appearance, aroma, texture, taste and
overall, using a Likert scale.
