During ripening of the sweet cherries, there occurs increase in
fruit weight, soluble solids content, fructose, malic acid and
total antioxidant activity, as well as in bioactive compounds
and decrease in firmness and glucose level. The most rapid
fruit size increase occurs during the first week of ripening
(Blazkova et al., 2002). During ripening, an accumulation of
anthocyanins, especially cyanidin-3-O-rutinoside takes place
and produces the red-purple colour typical of the fruit. As
cherry skin colour changes from full light red to full dark, fruit
weight, soluble solids content, TSS/TA ratio increases
