Retail market prices of fonio reveal the demand for quality characteristics in Bamako, Mali.

African consumers' expectations concerning quality of food products are great. In spite of constrained budgets, we showed that market retailed prices revealed quality preferences of the consumers and not only production costs. In very poor countries like Mali, food innovation is limited by the very low purchasing power of the population. However, technological food product or process innovations are possible and sometimes valuable. Demand driven innovation may lead to open new markets, opportunities for small and medium scale enterprises and to improve consumers' welfare. Based on this assumption, technical research was done to provide new food products. In this paper, using both sensory test and a hedonic price approach, we estimated consumer demand for different characteristics of fonio, a West African cereal, and showed that poor consumers do have quality requirements and actually pay for it. We showed that the shadow or hedonic price paid for quality characteristics is small but significant. A comparison of sensory test and market study showed a convergence between what people say they prefer and what they really pay for. Results were consistent and showed directions for technological improvement of the product and its production process. The Partial Least Square method was used to estimate hedonic prices of the different modalities of fonio quality traits.Demand and Price Analysis,

Sensory diversity of fonio landraces from West Africa

This study aims to establish if there is some sensory variability among fonio landraces. Fonio, the oldest indigenous and very tasty cereal growing in West Africa, is usually consumed as a couscous. Group interviews of consumers were conducted in Bamako, Mali to identify the main quality criteria of a cooked grain. Fonio grain must be swollen, not sticky with a soft consistency, pale and containing low impurities. Sensory properties of 20 fonio landraces from Mali, Guinea and Burkina Faso were established using a descriptive sensory analysis. Five sensory descriptors were chosen among the quality criteria. Each landrace was tasted and scored in triplicate by a group of 18 trained panellists. Principal component analysis and hierarchical cluster analysis were used. The 20 landraces clustered into four sensory classes. Sensory criteria of variability were first visual characteristics (colour and impurities) and then the consistency of cooked grains. Landraces from Guinea and Mali were variable for both visual and textural characteristics; those from Burkina Faso appeared to be more homo-genous. The sensory variability of fonio offers to processors, who intend to promote this tiny cereal both in the sub-region and beyond, the possibility to choose adapted landraces to develop new products

This method was interesting since it solved the OrdinaryLeast Square method's colinearity problems
