Despite the fact that many infant formulas exist, malnutrition is still a problem in Cameroon. According to previous studies, this malnutrition could result from inadequate feed practises, lack of time from parents and the fact that mothers are not involved in the formulation process. The aim of this study is to improve the adoption of locally produced instant formulas by the integration of mothers in the formulation and price determination processes. The methodology adopted is made of formulation of instant formula from germinated maize, rice, soya bean and sesame by wet and dry methods, then the determination of acceptability, purchased intention and psychological price by 50 mothers and wet nurses and finally the evaluation of production cost. The results show that flour produced by wet method with an equal proportion of germinated maize, rice and soya bean have the highest production yield (26%), are the most appreciated and have the highest purchased intention (47%). The production cost of this flour (125 FCFA/30 g of flour) is the lower than the price of instant flour sell in the markets (250 à 300 FCFA/50 g of flour). Moreover, the energy density of the produced flour satisfied Codex Alimentarius requirements in terms of infant formula.

Participatory varietal selection is a process that is gradually gaining ground in terms of its ability to improve the results of a selection. This work would identify the preferences of its kind on the choice of the variety of rice in Cameroon. The hypothesis states that rice varietal selection in Cameroon is significantly influenced by gender. Data were collected through individual questionnaires and group interviews from 240 producers in the Mbam, North and Northwest. Using inferential statistic and logistic regression, the study showed that gender has no effect on the choice of rice varieties in Cameroon at all the growing stages.
