Effect of gamma irradiation on moisture sorption isotherms of cowpeas

Abstract

The effect of gamma irradiation on moisture sorption isotherms of cowpeas was investigated The nonirradiated 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.
