Valorization of Carrot Pomace: UVC Induced Accumulation of Antioxidant Phenolic Compounds

Carrot pomace is the main waste residue obtained during carrot juice extraction. Plant tissues respond to abiotic stresses (i.e., wounding stress and ultraviolet C (UVC) radiation) by accumulating bioactive compounds. Due mechanical damage occurring extraction, undergoes extreme stress. In this study, effects of UVC light (11.8 W m?2, 0–120 min) storage time (48 h, 25 °C) on accumulation phenolics compounds antioxidant activity (AOX) were evaluated. that was non-treated with (control) showed a 709.5% increase in total at 48 h. A high correlation AOX values against (R2 = 0.87) observed, indicating contributors tissue. After treatment, radiated for 120 min an (40.4%) chlorogenic acid (CHA) content. At 24 protocatechuic 3,5-dicaffeoylquinic acid, which not detected before storage, 166.5 mg/kg 169.4 mg/kg, respectively, treated pomace. Chlorogenic highest (143.6%) h control. Valorization achieved increasing its concentration through radiation.
