4. Conclusion
In summary, the present work showed that using a salt substitute
containing L-his and L-lys induced a decrease of 53.79% in Na
content of the dry-cured loins, delayed lipid oxidation and produced
a slightly higher lipolysis in the loins, resulting in larger
content of free fatty acids and higher phospholipase activity at the
end of the ripening stage. Furthermore, the activities of phospholipase
and acid lipase in porcine loin were activated by L-his and Llys.
It was demonstrated that the introduction of L-his and L-lys not only produced a reduction in sodium content but also promoted
physicochemical properties in dry-cured loin.
