Abstract:

The water adsorption and desorption kinetics of okara were determined at different relative humidities (51.4-83.6%) at 30°C. Initial rates of water sorption and the specific rate constants showed different responses to increased RH. Both the adsorption and desorption rate constants dropped significantly at RH 51-55%; this behaviour is related to occurrence of glass transition phenomenon.
