Degradation of anthocyanins revealed as a color change, and in
particular in decrease of lightness L* and color parameter a*, was
observed for all cherries after drying. The value of E obtained
for the samples dried solely convectively was the highest of all
other performed drying tests. It proves that a long-lasting hot
air drying in a high temperature causes a meaningful color alteration. The results of E for the samples dried in intermittent
conditions are smaller than those dried at constant air temperature. Furthermore, the osmotic pretreatment resulted in better
quality preservation after intermittent drying. However, the best
quality cherries from the color point of view were obtained after
