A cyanidin-3-O-rutinoside dominant anthocyanin system from Osmanthus fragrans fruit peel: Composition, color behavior and thermal stability
This study evaluated Osmanthus fragrans fruit (OFF) peel as a potential source of anthocyanin-based natural colorants. Anthocyanins were extracted using acidified ethanol and purified by macroporous resin adsorption, yielding a pigment-rich extract with a recovery of 10.4 ± 0.2% from dried peel. HPLC–MS/MS analysis ind...
