On the other side, microorganisms do not
contribute to the desirable fl avor of cooked
ham as occurs in other meat products, such
as fermented sausages (Toldr á and Flores
2007b ). The contribution of microorganisms
to the fl avor of cooked ham is insignifi cant,
but they are responsible for acidifi cation and
formation of off - fl avors generally during
storage (Samelis et al. 1998 ). The refrigerated
storage of sliced cooked ham under
vacuum or modifi ed atmospheres leads to
alterations in the sensory characteristics of
the product, such as color defects, off - odors,
and slime formation. Therefore, the refrigerated
storage of cooked ham modifi es the
volatile composition due to the metabolism
of lactic acid bacteria that generates typical
fermentation products, such as methyl
branched alcohols and aldehydes (Leroy et
al. 2009 ). In addition, lipid oxidation is
another phenomenon that generates oxidation
products, such as unsaturated aldehydes
(De Winne and Dirinck 1997 ) that are not
present in fresh cooked ham.
