water sorption isotherms of destoned and ground saiadey Jaul type dates were obtained at 30,40.50 C.using the gravimetric methods.Data were analyzed by applying the GAB,BAT ,Smith,Iglesias and Chrife,Halsey ,Henderson and Oswin Models.Isosteric heat of sorption value was calculated using the Clausius-Clapeyron Equation and tried to be as afunction of moisture content of dates. It was found that the experimental data fitted well to ,smith ,I glesias and Chirife ,Halsey, Henderson and Oswin equation, which are suitable for high sugar foods.Isosteric heat of sorption for dates varied from 0,9 to - 1,84 KJ/mol as moisture content changed from 11,0 to 18,0%.
