dc.description.abstractCowpeas (Vigna unguiculata L. Walp) are leguminous seeds widely produced and consumed in most developing countries of sub-Saharan Africa where they are a good source of affordable proteins, minerals and vitamins to the mainly carbohydrate-based diet of sub-Saharan Africa. At storage cowpea may be attacked by insects that cause severe damage to the seeds. The objective of this study was to investigate the effects of gamma irradiation on some physical and sensory characteristics of cowpea seed cultivars. Four cowpea cultivars were irradiated with gamma radiation at dose levels of 0.25, 0.50, 0.75, 1.0 and 1.5 kGy. Moisture content, thousand grain weight and bulk densities were determined as well as the amount of water absorbed during soaking and some sensory characteristics were equally determined. All the physical parameters studied were not significantly (p>0.05) affected by the radiation. There was no significant (p>0.05) effect of the radiation on the sensory attributes like flavour, taste, texture, softness and colour of the cowpea seeds. Similarly, the radiation did not affect significantly (p>0.05) the acceptability of the treated cowpea cultivars. © 2011 Elsevier Ltd.en_US
