In addition to these databases, the bibliographies of retrieved articles were
also reviewed to obtain additional citations. Titles and abstracts of the references
were scanned and full papers that were likely to contain comprehensive information
on the anthocyanin contents of the fruits were obtained. Because some
anthocyanins are not stable during storage [120], only fresh fruit and freshly
squeezed juice were considered for anthocyanin content. Fruits are considered
only if their total anthocyanin contents were >20 mg/100 g fruit. The rank order
of anthocyanin contents was evaluated for each fruit. If different rank orders were
found in different papers, the anthocyanins are listed and separated by commas
in Table 1. When too many references were found, only recent references on the
common fruit varieties are cited.
