Ninety green turkey hams were equally divided into 3 groups and cured with 3 g/100 g, 4 g/100 g or 5 g/
100 g salt. Cured hams were then dry-ripened by following the same procedure as dry-cured pig ham
with some modifications. The effect of curing salt on lipids’ oxidation and volatile compounds formation
by dry-cured turkey hams was studied. The TBARS values and the total content of volatile compounds in
ripened turkey hams decreased significantly as salt concentration increased (p < 0.05). The amount of
curing salt was positively correlated with total aldehydes content (r ¼ 0.982), but negatively correlated
with alcohols, ketones and alkanes contents (r ¼ 0.975, 0.649 and 0.807, respectively). Principal
component analysis results showed that the first principal component (PC1) was dominated by aldehydes,
alkanes and some alcohols, and explained 69% of total variance. These results indicated that
reduced curing salt level result in increased formation of flavour-active volatiles in dry-cured turkey
hams.
