Abstract:		"The effect of dietary supplementation with either vitamin E (300 ppm) or a red wine extract rich in polyphenols (900 ppm) in an omega-3 enriched concentrate on the volatile fraction of lamb meat was assessed. The effect of refrigerated storage (0 and 6 days) under high-oxygen atmospheres (70% O(2)/30% CO(2)) was also studied. Extraction and analysis of the volatile compounds was carried out by headspace solid-phase microextraction (HS-SPME) and GC-MS, respectively. Vitamin E supplementation led to lower levels of lipo-oxidation compounds, such as 2-heptanone and 1-penten-3-ol. The red wine extract was less efficient against lipid oxidation than vitamin E but more efficient than the control (no added antioxidants). The levels of numerous lipid-derived compounds were found to be lower after 6 days of storage which could be due to further interactions with protein-related compounds"
