UPLC-QqQ-MS/MS-based phenolic quantification and antioxidant activity assessment for thinned young kiwifruits

For the first time, thinned young kiwifruits (TYK) have been investigated as a source of deserted agriculture resource and evaluated for their phenolic characteristics along with antioxidant capacity. Two batches of TYK in different maturity stages (TYK1 and TYK2) and mature kiwifruits (MK) were sourced from three New Zealand cultivars. Comparing with MK, the TYK, especially TYK1, exhibited significantly higher contents of total phenolics (7.92...
