Unfortunately, EVOO is also easy to falsify.
In fact owing to its
prominence, it has always been illegally mixed with cheaper and
low-quality oils,especially to obtain EVOO sold in supermarkets and discount stores
at low cost.
The so-called lampante low-quality olive oils cannot be
used as raw foodstuff for direct human consumption, as they have
an acidity level that is too high, and their volatile profile is characterized
by ‘soft’ off-flavours, derived from low-quality olives or
from inappropriate procedures during oil extraction or storage.
