✦ Synopsis
Moisture adsorption isotherms of Tarhana were determined at 25 °C and 35°C. As the temperature increased, the adsorbed moisture content decreased at water activities between 0.2 and 0.9. The experimental sorption data obtained were applied to the Halsey, Harkins-Jura, Smith, BET and Freundlich isotherm equations to test ®tness of these equations to Tarhana. The order of best ®t or sorption data obtained for Tarhana was Halsey b Harkins-Jura b Smith b Henderson b BET b Freundlich. The obtained sorption data ®tted the Halsey, Harkins-Jura and Smith isotherm equations quite well in the 0.2±0.9 water activity range; However, the best ®t was obtained in the Freundlich, BET and Henderson isotherm equations in this water activity range.
