| Özet |
| Purple onion (Allium cepa L.) peels, an abundant agro-industrial by-product, are particularly rich in flavonoids and anthocyanins with strong antioxidant potential. The effective recovery of these biologically active compounds enables the conversion of plant residues into high value-added products, supporting both clean-label ingredient development approaches and circular bioeconomy strategies. This study aimed to optimize ultrasound-assisted extraction (UAE) conditions to maximize the yield of total phenolic content (TPC) and total monomeric anthocyanins (TMAC) from purple onion peel s. A central composite design based on response surface methodology (RSM) was employed to systematically investigate the effects of four independent variables: ethanol concentration (0-100%), solvent-to-solid ratio (10-60 mL/g), extraction temperature (20-60 °C), and extraction time (30-120 min). The results indicated that solvent composition, temperature, and duration significantly influenced bioactive compound recovery. TPC ranged from 237.06 to 1230.96 mg GAE/100 g, while TMAC varied between 1645.84 and 12357.50 mg/kg. Multi-response optimization identified 95% ethanol, 55 mL/g solvent-to-solid ratio, 40 °C, and 105 min as optimal conditions, which were subsequently validated through confirmatory experiments. Extracts obtained under these optimized conditions exhibited desirable color parameters, low water activity values (0.20-0.52), indicating high stability and functional applicability in various formulations. Overall, the integration of UAE with RSM offers an efficient, scalable, and environmentally friendly approach for the extraction of … |
