Fig. 1. HPLC traces of benzyl esters of oxidised fatty acids (OFA) from enriched spaghetti after 12 months under light (upper trace) and at the beginning of storage (lower
trace). IS1: benzyl caproin; IS2: benzyl heptadecanoin. Peaks on the right of OFA are benzyl esters of non oxidised fatty acids. For analytical conditions, see Section 2.
