Moisture desorption isotherms (EMC/ERH) of canola cultivar of 'Option 500' determined at 30, 40, 50 and 60 °C using the standard gravimetric static method over a range of relative humidity from 11% to 81%. The experimental desorption curves were ?tted by four equations: modi?ed Henderson, modi?ed Chung-Pfost, modi?ed Halsey and modi?ed Oswin. The modi?ed Oswin model was found as best model to describe desorption isotherms of canola. The net isosteric heat of desorption of canola was determined
