MODELING WATER-ABSORPTION IN SOYBEAN, COWPEA AND PEANUTS AT 3 TEMPERATURES USING PELEG EQUATION

Peleg's equation was used to model moisture sorption in soybean, cowpea and peanuts at 2°C, 25°C and 40°C. Peleg K1 varied with temperature while Peleg K2 was not relatively affected. Peleg K2 could be used as a water absorption parameter. The lower the K2 value, the more water was absorbed. Values of K1 and K2 were predicted for each of the cultivars of the legumes studied. There was no significant (P > 0.05) difference in either K1 or K2 value for both the dehulled and undehulled peanuts. Peleg equation with the predicted constants gave fairly good fit for water absorption in the legumes. Copyright © 1990, Wiley Blackwell. All rights reserved
