Description In this study, physicochemical changes, phenolics profile, and antioxidant
potential in three grape varieties during berry development were assessed.
The results showed a significant difference in stage-wise accumulation of
phenolics. The fully matured Bangalore blue grapes showed the high total
phenolic content (1484.87 mg GAE/100 g) followed by Krishna Sharad
(1361.42 mg GAE/100 g) and Dilkhush variety (1108.61 mg GAE/100 g). The
Krishna Sharad grapes contain the high anthocyanin content (1622.7 mg/kg)
at full maturity. A similar pattern was observed for flavonoid content. The
UPLC-PDA analysis showed that chlorogenic acid, catechin, epicatechin, and
hesperidin were present in significant amount in Bangalore blue grape
variety. In Krishna Sharad, gallic acid, chlorogenic acid, hesperidin, catechin,
hesperetin were significant phenolics. Dilkhush grapes were rich in catechin,
chlorogenic acid, and caffeic acid. The Bangalore blue and Krishna Sharad
showed high antioxidant potential at full maturity in DPPH and ABTS activity.
Collectively, the results suggest that berry development stages have an
impact on its antioxidant properties, bioactive content, and berry
composition.
