The processing of the Iberian sausage “Chorizo” has been described by Broncano et al. (2011). The sausages (n ¼ 40) were divided into four pieces, each one assigned into one of the four sampling days. At 0 day, samples were taken at the end of processing (no storage). The rest of the samples were packaged under vacuum and were stored under illumination (600 lx) at 18 C (to simulate commercial conditions) and maintained up to 45 days (enough time to appreciate if this kind of “chorizo” develops lipid and colour oxidation).
