Abstract

The aim of this study was to investigate lipolysis and lipid oxidation in smoked dry-cured ham during the 12-month production period. The study was performed on the Biceps femoris (BF) and Semimembranosus (SM) muscles at 5 different production stages (raw ham, after salting, after smoking, after drying, after ripening). Analysis of total fat content were performed by Soxhlet method, free fatty acid composition (FFA) by gas chromatography and degree of fat oxidation by thiobarbituric acid test (TBARS test). The total fat content in both muscles increased after the drying stage, with significantly higher (p<0.05) values in SM during processing. Lipid oxidation increased progressively in both muscles during the production, although with greater intensity in SM. The FFA profiles of the studied muscles changed significantly (p<0.05) during processing. At the end of processing, BF and SM showed similar FFA profiles and contained 38.28 and 38.10 % SFA, 52.17 and 50.45 % MUFA, and 9.55 and 11.24 % PUFA, respectively. At the end of processing, a significantly (p<0.05) higher proportion of fat and a higher degree of fat oxidation were found in the SM muscle compared to the BF muscle of smoked drycured ham.
