Identification of degradation pathways and products of cyanidin-3-sophoroside exposed to pulsed electric field

► Cy-3-soph degrades into quinonoid benzoyloxyphenylacetic acid esters after PEF. ► The main degradation pathway of Cy-3-soph by PEF is different from heating. ► Cy-3-soph is degraded through Baeyer-Villiger oxidation during PEF treatment.
