The isotherms and the humidity sorption heath were determined at 26, 32 and 38 ºC. The range of water activity used was 0.10 to 0.90. The tendency of the isotherms was similar to the form which is characteristic to sorption isotherms of type III. The effect of temperature on the humidity sorption isotherms show that granulated panela can get more hygroscopic with increasing temperature, which makes this product another exception to the general rule that humidity sorption decreases with increasing temperature
