Description	Adsorption isotherms of black currant, black elderberry and chokeberry were obtained at 10, 25 and 40°C. Generally, increasing temperature decreased adsorbed moisture particularly at 10°C, whereas the adsorption was similar at 25 and 40°C in the range of 0.10-0.75 aw for all the berry samples. All the berries sorbed more water at 40°C than at 10 or 25°C above 0.75 aw. Of the six sorption models, Peleg's model gave the best fit. The net isosteric heats of adsorption were obtained using Clausius-Clapeyron equation showing that the adsorbed water is strongly bound to adsorbent at low moisture content. The glass transition temperature concept was also discussed. Based on the results of the study and the literature reviewed, the chilled storage has a favourable effect on the quality and shelf life of the dried berries.
