ABSTRACT
In order to reduce post-harvest losses of yams in Côte d'Ivoire by more efficient conservation methods, four varieties of local yams (Lokpa, Assawa jaune, Assawa blanc, Kponan) were pretreated with a dilute solution of juice of lemon to 1% before the production of the different flours, according to the methods of the AOAC. The results indicate that the pretreatment reduced the loss of levels of physicochemical parameters such as proteins, total sugars and reducing sugars during cooking. However, the pretreatment did not significantly influence (p ≥ 0.05) the swelling and solubility of the flours obtained. Couscous made from pre-cooked flour was generally appreciated, especially those of flours preserved in 100 μm thick bags. In terms of grading, the most accepted couscous was that of the Assawa jaune variety followed by the Kponan variety, then the Assawa blanc variety and finally the Lopka variety.
