Influence of Cultivar and Storage Conditions in Anthocyanin Content and Radical-Scavenging Activity of Strawberry Jams
The strawberry jam is rich in bioactive compounds. It
is economically and commercially important and widely consumed.
Different strawberries cultivars can be used for its preparation,
however, a careful selection should be performed to guarantee the
preservation of bioactive compounds during jam storage. Two
strawberry cultivars (Camarosa and American 13) were analyzed by
HPLC, three anthocyanins: cyanidin-3-glucoside, pelargonidin-3-
glucoside and pelargonidin-3-rutinoside were quantified. Camarosa
strawberries presented significantly higher concentration of
anthocyanins (p<0.05), and greater radical-scavenging activity.
During jam storage period significant changes occurred regarding
anthocyanin composition, at 15 and 60 days. Jams stored in dark
presented slightly higher levels of anthocyanins. No significant
changes were observed in jam-s radical-scavenging activity between
15 and 60 days of storage under dark and light conditions. Camarosa
cultivar is more appropriate for strawberry jam preparation because it
contains higher levels of anthocyanins and higher radical-scavenging
activity.
