Abstract
A commercial aperitif containing E110 and E122 dyes is exposed to photo-irradiation in solar box under conditions chosen to simulate sun light irradiation. After 16 days of irradiation the red-coloured aperitif assumes a very pale yellow colour. HPLC–diode array–MS/MS analysis evidences the presence in the commercial aperitif of some impurities with naphthalene-based structures. The structures for the photodegradation products are proposed.
