Abstract

Moisture absorption in black gram was investigated at 30, 40, 50 and 60°C using Peleg Model. The Peleg constant K, varied with temperature. At a given temperatures lower the K, water absorbed was lowering. The Peleg constant K2 was almost unaffected by temperature and could be used to predict the equilibrium water absorption. The Peleg's equation with predicted constants gave fairly good fit for water absorption in black gram.
