Yams are not among the most common sources of industrial starch, which are mostly imported at a cost. Exploiting alternative sources of starch would lessen the burden of its importation. Starches from four local varieties of Dioscorea rotundata namely Pona, Labreko, Asobayere and Muchumudu were analyzed for their physicochemical and functional properties.

The effect of heat treatment on edible yam (Dioscorea cayenensis-rotundata cv. “Zrèzrou”) polyphenol oxidase activity was studied over a range of 35 to 75°C. Under all conditions investigated, a first-order kinetic model could describe the thermal inactivation data with k-values between 0.004 and 0.108 min-1 .

The improvement of yam (Dioscorea spp) nutritional quality is now an important challenge for yam breeders and producers. In order to identify yam parents with high technological potential for their use in varietal improvement schemes, two most dominant cooking forms (boiled and pounded) were considered. A total of 48 yam (Dioscorea rotundata Poir.) cultivars used as parents in Benin yam breeding program were evaluated. Trained and untrained panelists were invited to taste coded and randomized samples of boiled and pounded yam for the various tests using appropriate methods.
