The anthocyanins suffered significant losses during both frozen
storage of the fruits for 6 months and refrigeration of the juice for
10 d (Tables 3 and 4). With respect to the anthocyanin profile, each
compound identified showed a different behavior during 6 months
of frozen storage, some being degraded and others not. During
refrigeration of the juice, all the compounds degraded in practically
the same proportions (mean of about 83%), cyanidin-3-glucoside
showing the greatest losses.
