Characterization of Phenolics in Rejected Kiwifruit and Their Antioxidant Potential

Kiwifruit hold significant nutritional value and are a good source of antioxidants due to their diverse range bioactive compounds. waste is generated throughout the food supply chain, particularly during transportation storage. rejected from retail market unfavorable appearance still possess potential economic as kiwifruit abundant in phenolic The present work studied profile antioxidant kiwifruit, including SunGold (Actinidia chinensis), Hayward deliciosa), round organic deliciosa). Regarding phenolics estimation, possessed highest TPC (0.72 ± 0.01 mg GAE/g), while exhibited TFC (0.05 0.09 QE/g). In assays, showed activities DPPH (0.31 0.35 AAE/g), FRAP (0.48 0.04 ABTS (0.69 0.07 •OH-RSA (0.07 0.03 AAE/g) FICA (0.19 EDTA/g), whereas RPA (0.09 0.02 TAC (0.57 AAE/g). Separation characterization were conducted using LC-ESI-QTOF-MS/MS. A total 97 tentatively characterized (71 phenolics), (55 (9 phenolics). Hydroxycinnamic acids flavonols most common three samples. quantitative analysis was by HPLC-PDA found that chlorogenic acid (23.98 0.95 mg/g), catechin (23.24 1.16 quercetin (24.59 1.23 mg/g) notable presence compounds corresponding capacities indicate rescuing for further utilization commercial exploitation.
