- The effect of chestnuts inclusion on Celta pig diet was tested.
- Changes during ripening and vacuum-packed storage of Galician chorizo were studied.
- Physicochemical and oxidative parameters were affected by chestnut inclusion.
- Fatty acids from neutral and polar lipids were influenced by finishing diet.
The effect of the inclusion of chestnuts in the finishing diet of Celta pig breed on the characteristics of Galician chorizo, a traditional dry-cured sausage, along the ripening process and vacuum-packed storage was studied. In general, no significant differences between diets (chestnut, mixed and concentrate diet) were obtained for weight losses, chemical composition, physico-chemical characteristics, and lipolytic and oxidative parameters. A significant effect of the diet was observed on some fatty acids from total and neutral lipids, obtaining lower contents of C18:2n-6 and C20:2n-6 and higher contents of C18:1n-9, C18:3n-3 and C20:4n-6 when chestnuts where included in the diet. In polar lipids, after dry-ripening, lower contents of C18:2n-6 and total polyunsaturated fatty acids and higher contents of C18:1n-9 and the sum of monounsaturated fatty acids were found in sausages from chestnut diet. Free fatty acids profile during vacuum-packed storage changed to a larger content of C16:0. The distinction between sausages was procured when a discriminant canonical analysis was performed for fatty acid contents.
