Does information on food production technology affect consumers' acceptance of biofortified foods? Evidence from a field experiment in Kenya.
This paper combines Just-About-Right (JAR) sensory evaluation and means-end chain (MEC) analysis to examine consumer evaluation of the sensory attributes of conventionally bred biofortified orange-fleshed sweetpotato (OFSP). It specifically examined the role of information on biofortification pro...
