Caracterização físico-química, composição fenólica e atividade antioxidante de genótipos e cultivares comerciais de frutos de mirtileiro

[摘要] The physicochemical characterization, antioxidant potential and phenolic composition of fruits of six genotypes (BB3, BB4, BB6, PW1, PW2 and PW5) and seven commercial cultivars (Bluebelle, Bluegem, Briteblue, Climax, Delite, Powderblue and Woodard) were carried out of blueberry, from the 2019/2020 production cycle. Color, soluble solids content, pH, titratable acidity, antioxidant activity (DPPH and ABTS), total phenolic compounds, total flavonoids, total anthocyanins and individual anthocyanins were analyzed. In general, all genotypes and cultivars are rich in phytochemicals. The genotypes PW1, PW2, PW5, BB3 and the cultivars Bluegem, Briteblue, Climax and Delite stand out. Thus, the blueberry genotypes in this study are considered as promising for the food industry and also for fresh consumption as commercial cultivars already consolidated in the fruit market, in view of the excellent phenolic composition present in these small fruits.
