The effect of gamma irradiation on moisture sorption isotherms of cowpeas was investigated The non-irradiated and irradiated cowpeas exhibited the typical three stage sigmoidal curve found in most foods. There was also a concomitant increase in the equilibrium moisture content (EMC) as relative humidity increased for non- and irradiated cowpeas. Drum cowpea (15 Gy) had the highest rate of water absorption. Generally, the amount of water absorbed by irradiated cowpeas is generally higher than non-irradiated cowpeas.
Key words: Cowpea, irradiation, moisture, sorption.
