“…In addition, some authors (Lin and Yen, 1999a;Lin and Yen, 1999b;Saide and Gilliland, 2005) have demonstrated MDA-scavenging abilities or even inhibition of linoleic acid peroxidation by starter cultures, although these antioxidant activities originated from cellular lysis and release of intracellular metabolites. However, in some cases such as iron-fortified yogurt (Hekmat and McMahon, 1997) or yogurt from unsaturated fatty acids-enriched milkbase (Barrantes et al, 1996;Boylston and Beitz, 2002;Let et al, 2007;Xu et al, 2006), lipid oxidation products have been detected in greater amounts.…”
