Modeling water sorption in okara soy milk
Moisture sorption isotherms of okara soy milk were determined using the gravimetric method in the range 20 - 50°C. The sorption isotherms exhibited hysteresis along all the water activity range (0.1 - 0.9). The amount of sorbed water increased as the temperature was decreased. The GAB and Halsey mod...
