Segregation of blackberry cultivars based on the fruit physico-chemical attributes

Abstract

Blackberries are considered as a rich source of phyitochemicals with high nutraceutical value and beneficial health effects. The objective of this work was to determine the berry size and composition status of blackberry cultivars grown under Serbian conditions. Fresh berries of seven blackberry cultivars ('Black Satin', 'Dirksen Thornless', 'Chester Thornless', 'Thornfree', 'Čačanska Bestrna', 'Loch Ness' and 'Navaho') were used as a plant material during two growing seasons. According to the results, the highest berry size was found in 'Čačanska Bestrna' and 'Loch Ness', dry matter (DM) and titratable acidity (TA) in 'Chester Thornless' and pH value in 'Dirksen Thornless' cultivars. The highest content of soluble solids (SSC), sugars content, SSC/TA rate and total sugars (TS)/TA rate was observed in 'Navaho', and mineral mater (MM) in 'Loch Ness' and 'Chester Thornless'. The highest total phenolics content (TPH) and total antioxidant capacity (TAC) were found in 'Black Satin', total flavonoids content (TFC) in Thornfree, and ascorbic acid (AA) in 'Loch Ness'. Based on the present results, the strong relationships between some phytochemicals, especialy between bioactive compunds, were observed. On the basis of principal component analysis (PCA), the cultivars were segregated based on the better quality attributes, which were observed in 'Navaho' and 'Loch Ness', somewhat in 'Chester Thornless' and 'Black Satin'.

Investigation on High-Value Bioactive Compounds and Antioxidant Properties of Blackberries and Their Fractions Obtained by Home-Scale Juice Processing

“…This finding shows that bioactive compounds content is higher in samples coming from a region with a milder climate in terms of the temperature and amount of precipitation. Our data recorded for the L-AsAc content of fresh blackberry samples are comparable with those reported in different blackberry cultivars by Milosevic et al [46].…”

Gluten-free crispbread with freeze-dried blackberry: quality and mineral composition

“…The addition of BP to crispbread increased its calcium content by 71%, potassium by 57%, iron by 46%, copper by 19%, magnesium by 16% and manganese by 12%. Blackberries are considered as a rich source of phytochemicals with high nutraceutical value and beneficial health effects (Milosevic, Mratinic, Milosevic, Glisic, & Mladenovic, 2012). These berries are also a good source of essential nutrients such as manganese, magnesium and potassium as reported by Amidžić Klarić, Klarić, Velić, and Vedrina Dragojević (2011).…”
