No significant difference in moisture content was observed between
the S-loin group and SS-loin group (P > 0.05) during processing
(Fig. 1). Similar results were observed in dry-cured ham
salted with mixtures of NaCl, KCl and CaCl2 in Armenteros' work
(2012), who found that moisture content was not significantly
influenced by the type of salt substitution during manufacturing.
However, the Aw in SS-loin was 2.45% and 3.51% more than that in
S-loin (P < 0.05) at 13 days and 18 days of drying-ripening,
respectively. However, no significant difference in Aw was found
between SS-loin and S-loin until 8 days of drying-ripening
(P > 0.05). This could be explained by the reduction of the Na ion
in the SS-loin.Water molecules have a very strong interaction with
the Na ion and a weak interaction with the K ion, i. e. the hydration
level between NaCl and KCl was in the order of NaCl > KCl (Haard &
