Title: Influence of Cultivar and Storage Conditions in Anthocyanin Content and Radical-Scavenging Activity of Strawberry Jams
Issue Date: 2012
Abstract: -The strawberry jam is rich in bioactive compounds. Itis 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 thepreservation of bioactive compounds during jam storage. Twostrawberry cultivars (Camarosa and American 13) were analyzed byHPLC, three anthocyanins: cyanidin-3-glucoside, pelargonidin-3-glucoside and pelargonidin-3-rutinoside were quantified. Camarosastrawberries presented significantly higher concentration ofanthocyanins (p<0.05), and greaterradical-scavenging activity.During jam storage period significant changes occurred regardinganthocyanin composition, at 15 and 60 days. Jams stored in darkpresented slightly higher levels of anthocyanins. No significantchanges were observed in jam's radical-scavenging activity between15 and 60 days of storage under dark and light conditions. Camarosacultivar is more appropriate for strawberry jam preparation because itcontains higher levels of anthocyanins and higher radical-scavengingactivity
