the quality of the dried cherries was judged on the basis of the color and water activity change. The color assessment was realized through evaluation of the color difference (E), measured with the colorimeter CR-400 Konica Minolta (Japan). The color of the cherry samples was indicated by CIELab color scale L*, a*, b*, where L* is
lightness, a* the color parameter (color space from red to green) and
b* represents color space from yellow to blue. E was calculated
according to the following formula:
