Tocopherol content, weight loss and instrumental color analysis of Iberian dry-cured ham as affected by rearing and feeding systems

Effect of Breed Purity and Rearing Systems on the Stability of Sliced Iberian Dry-Cured Ham Stored in Modified Atmosphere and Vacuum Packaging

The long-term storage stability of three quality categories of sliced Iberian dry-cured ham defined by the Spanish Iberian Quality Standard (Black, purebred Iberian reared outdoors in Montanera system; Red, Iberian × Duroc crossed (50%) pigs reared outdoors in Montanera system;, and White, Iberian × Duroc crossed (50%) pigs commercially fed) and packaged under vacuum and modified atmosphere packaging (MAP) was studied. Commercial category affected the shelf life, being Black and Red presented the highest lipid oxidation during storage, whereas the effect of packaging was not as clear as the effect of commercial category. MAP preserved more the colour and the antioxidants content than vacuum packaging, while this latter reduced lipid oxidation development and maintained better the brightness and flavour of slices than MAP.

Nutritional composition of dry-cured ham and its role in a healthy diet

Dry-cured ham is a traditional product with a strong presence in markets in the Mediterranean area. It is very popular with European consumers and is of enormous economic importance for the meat industry in the Mediterranean area. Although the great palatability of ham largely outweighs other considerations, aspects relating to health and wellbeing are increasingly important factors in consumer decisions. The potential role of ham in a context of healthy nutrition has not been clearly elucidated, especially considering that origins and production methods of dry-cured hams can induce differences in composition. The object of this review was on the one hand to provide an analysis of the components of dry-cured ham and their role in a healthy diet, and on the other hand to suggest possible strategies for improving its nutritional composition.
