Abstract :The chemical fruit composition, phenolic profile, and corresponding total antioxidant activity of bilberry insert ignore into journalissuearticles values(Vaccinium myrtillus); and 2 commercial blueberry cultivars insert ignore into journalissuearticles values(Vaccinium corymbosum); were analyzed. Results from this study showed that cultivar Berkeley yielded the highest glucose and fructose contents insert ignore into journalissuearticles values(70.8 and 88.8 mg/g FW, respectively);, and the sweetness index expressed a similar trend, achieving the highest value for cultivar Berkeley insert ignore into journalissuearticles values(279.2);. Citric acid was the major organic acid in the berries tested. V. myrtillus yielded a total organic acids value 2-fold higher insert ignore into journalissuearticles values(0.35 mg/g FW); as well as the highest vitamin C content insert ignore into journalissuearticles values(25.8 mg/100 g FW);. Among the flavonols measured, myricetin was most abundant in V. myrtillus insert ignore into journalissuearticles values(10.7 mg/g FW);, whereas the highest amounts of kaempferol and quercetin were detected in the blueberry cultivar Bluecrop insert ignore into journalissuearticles values(4.75 and 9.11 mg/g FW, respectively);. Despite the challenge of characterizing phenolic acids due to the complexity and natural variation in fruit composition, this study confirms that cultivars of V. corymbosum are rich sources of chlorogenic acid, particularly cultivar Bluecrop insert ignore into journalissuearticles values(71.2 mg/g FW);. Nevertheless, total phenolics were higher in V. myrtillus than in the cultivated blueberries, and consequently the highest level of total antioxidant capacity was recorded in wild bilberry insert ignore into journalissuearticles values(6.16 mg asc/g FW);. This semicomprehensive study characterizes the fruit quality attributes and illustrates differences in the content of taste- and health-related compounds present in these Vaccinium berries.
