in dry fermented sausages (Andrade et al., 2010) and in pork loins (Martín
et al., 2003). To the author's knowledge, little is known about the impact
of different yeast strains inoculated on the surface to the overall aroma
of long ripened dry cured hams.
The aim of this work was to evaluate the ability of selected, surfaceinoculated
yeast strains, isolated from dry-cured hams and previously
tested as biocontrol agents against toxigenic Penicillium nordicum, to
colonise hamsurface in dry-curing conditions, and influence the typical
volatile profile of dry-cured hams.
drying, first maturation, fat application and final maturation
(Simoncini et al., 2007). After the early cold processing steps (3–4
months at 0–3 °C for salting and resting), hams were twice yeastinoculated:
before drying (after the washing procedure) and at the
end of first maturation period (before fat mince application), to ensure
the permanence of the inoculated population throughout the production
process (Table 1). Nine hams/manufacturing plants were surface
sprayed with 10 ml of above mentioned yeast strains suspensions
(three hams/strain), while three hams/plant were not inoculated to
allow native mycetes to grow up (naturally contaminated control).
