Iberian pig production has become an important sector in the
Spanish economy, as their products, particularly dry-cured
hams, have acquired an extraordinary reputation at national and
international levels due to their high quality [1–3]. Traditional
production systems include a final fattening phase called
“montanera”, which is based on the consumption of natural
resources, mainly acorns, in extensive conditions. Different
studies have demonstrated that one of the most important factors
affecting the quality of Iberian pig products is the composition
of the diet during the above cited final feeding process [4].
Particularly, a conventional final feeding in extensive conditions
defines the composition and features of sub-cutaneous fat,
giving typical profiles for fatty acids and triglycerides
composition, as well as the delightful sensorial quality of
these products [5,6]
