Five batches of salchichon, which is a dry fermented Spanish sausage, were manufactured using backfat and meat enriched in polyunsaturated n-3 fatty acids and alpha-tocopherol. Raw materials were obtained from animals fed on diets of the same ingredients with the exception of the oil source [sunflower oil (batch control, C), linseed oil (L and LE), 1/1 (w/w) linseed and olive oil (LO and LOE)] and alpha-tocopherol quantity [20 mg/kg diet of alpha-tocopherol (C, L and LO) or 200 mg/kg diet of a-tocopherol (LOE and LE)]. A final product with a healthier polyunsaturated fatty acid n-6:n-3 ratio ( < 4) was obtained from all linseed oil-enriched batches as compared with the control (12). The batches of sausages manufactured with backfat and meat from animals fed on diets enriched in alpha-tocopherol and linseed, or linseed and olive oil with or without alpha-tocopherol supplementation show a higher lipid oxidative stability than those of diets enriched in linseed oil without alpha-tocopherol supplementation. Sausages of dietary treatment C, LE, LO and LOE did not show differences in water, protein, fat and ash contents, a(w), pH, texture profile analysis and sensory features (odour, colour, texture, juiciness and taste quality). Sausages manufactured with material from animals fed on linseed oil-enriched diets and no added a-tocopherol (L) showed an unfavourable rancidity degree detected by both 2-thiobarbituric acid-reactive substances (TBARs) index and sensory panel.
