摘要：

Rehydration characteristics of the maize (varieties MASYN VARS, IK93TZL COMP.3-YCI, ACR.86TZ ESR-W and IK937ZYTSR-W) and cowpea seeds (varieties 14C, 12C2, 19C and 12C1) were investigated at 25, 35 and 45C using Peleg model. The physical characteristics of the seeds observed were different among the varieties studied. The Peleg model applied can predict effectively the kinetics of rehydration of the seeds with R2 varying between 0.871 and 0.99.The Peleg constant K1 varied between 0.5773 and 1.177min/% for maize seeds and 0.0604 and 0.2417min/% for cowpea seeds. For the K2, the effect of variety and temperature was observed in this work. The equilibrium moisture content within the experimental range varied between 13.03 and 18.66kg/kg dry basis (d.b.) and 11.86 and 13.77kg/kg d.b. for cowpea and maize seeds, respectively. Temperature dependence of 1/K1 followed an Arrhenius-type relationshi
