Abstract

In this study, the usual procedures for determining sorption isosteric heats by the application of the Clausius-Clapeyron equation to sorption isotherms of grains was examined and isosteric heats of adsorption, desorption and total isotherms derived from various wheat, corn, rice and rapeseed cultivars were compared to those certain species. Isosteric desorption heats for shelled corn and rapeseed was found considerable higher than those of isosteric adsorption heat were. Isosteric adsorption heats for rice was found considerable higher than isosteric desorption heat. Sorption isosteric heats for all studied crop species were found the dramatically higher then those of total sorption isosteric heats.
