Meat was processed into Soppressata salami according to traditional protocol. Meat and Soppressata salami were analyzed for nutritional, textural and color parameters. Meat and Soppressata salami showed significantly higher proportion of unsaturated fatty acids in OUT than that in IND group. Ameliorated nutritional indexes in terms of n-6/n-3 ratio, and thrombogenic index were found both in meat and Soppressata salami in OUT group. Texture Profile Analysis showed lower values in the tested samples from OUT thanINDgroup. Lightness, redness, and chroma parameters were higher both in meat and Soppressata salami in OUT group;whereas hue parameter was lower in Soppressata salami from OUT pigs. Outdoor rearing improved fatty acid profile, nutritional indexes, color and mechanical properties of pork meat thanks to natural pasture, greater space allowance and physical exercise of animal during the fattening phase. Meat features strictly affected the quality of the Soppressata salami produced by using traditional protocol.展开更多
