For the blueberry fruits stored frozen at 18 8C, an average of about
59% degradation of the anthocyanins was found after 6 months of
storage. Considerable losses of total anthocyanins were reported
by Chaovanalikit and Wrolstad (2004a, b) for cherries stored frozen
at 23 8C. These authors found 88% degradation after 6 months of
storage and 67% in the first 3 months.
