Abstract
This study was conducted to investigate the physicochemical properties and antioxidant activities of strawberries from different cultivars and ripening stages grown in Korea. Fragaria ananassa ‘Seolhyang’ and ‘Janghee’ in unripe and ripe stages were used in this study. Overall, firmness of unripe fruits was harder than that of ripe fruits, whereas firmness of ‘Seolhyang’ was harder than that of ‘Janghee’. There was no significant difference in soluble solid content (SSC) between the two cultivars, whereas SSC increased when fruits matured. Total phenolic and flavonoid concentrations of ‘Seolhyang’ were greater than those of ‘Janghee’ cultivar. However, there was no ripening effect on total phenolic concentration in both cultivars. Total anthocyanin concentrations of the two cultivars were higher in ripe stage while that of ‘Janghee’ was greater than that of ‘Seolhyang’ statistically. Total antioxidant activities of ‘Seolhyang’ were greater than those of ‘Janghee’. Total phenolic and flavonoid concentrations were highly correlated with antioxidant activities but there was no correlation between total anthocyanins and total antioxidant activities.
