摘要：Moisture sorption isotherms of pigeonpea grain ( Cajanas cajan ) and dehulled splits of pigeonpea (dhal) at 10, 20, 30, 40 and 50°C were derived. The sorption data were treated according to many well-known sorption isotherm equations. The goodness of fit was evaluated on the basis of criteria such as the residual sum of squares, standard errors of estimates and mean relative deviation. It was found that the modified Chung-Pfost equation was the most satisfactory model for representation of the EMC data for pigeonpea grain up to 80% ERH. Modified Henderson equation was the most satisfactory model for representation of the EMC data for pigeonpea dhal.
