Although an analysis of variance did not show statistical
differences between the DE for compared samples, after 8 weeks of
storage the untreated samples had a DE value of only half compared
with whose US treated. Along with storage extension the observed
color changes nearly equalized. This can be explained by the fact
that the US treated samples, after 8 weeks storage, contained about
29% less anthocyanins (the compounds responsible for the color of
dried cherry) than the untreated sample after the same time of
storage, while after 24 weeks both samples contained only trace
amounts of anthocyanins (Table 6).
