Cover Story: Rowan (Sorbus aucuparia L.) is a resilient, polyphenol-rich fruit that is still underutilized. This study investigated how pre-treatment and extraction strategy affected the recovery of health-promoting phenolics and antioxidant activity from its fruits. Convective drying was compared with freeze-drying, followed by rotor–stator homogenization, ultrasound-assisted extraction, and Soxhlet extraction in ethanol. Freeze-drying roughly doubled total phenolics, and freeze-dried samples treated with ultrasound showed the strongest antioxidant capacity and favorable greenness scores. Soxhlet maximized phenolic and flavonoid yields but at a higher environmental cost. The findings guided the design of sustainable processes to valorize rowan as a source of natural antioxidants. View this paper
