Olive oil is mainly constituted by
trygliceridies. They represent the most important
group of alimentary fats.
Acid fats are distinguish in saturated and non
saturated; Olive oil has a composition of non
saturated acid fats extremely balanced:
- oleic-acid
|
73%
|
- linoleic-acid
|
9%
|
- linolenic-acid
|
0,3%
|
Saturated acid fats are 15% (average
composition)
|
Compared to other mammals, oleic-acid is the fat
mainly presents in the human body.
The linoleic-acid is contained in the oil with
the same proportions of the maternal milk, this
makes the extravergine olive oil extremely suitable
for childrens.
In the oil there are then polynsaturated acid
fats, defined essential because they cannot be
synthetized from the human body and therefore, they
have to be introduced by means of the
nourishment.
Beyond to this particular composition, we do not
have to neglect the presence of minor but
interesting components, from the biological point
of view. All these elements (Vitamin A, D, E, and
K, phenolic elements and others) have anti-oxidant
properties with consequent protecting effects.
Also from the point of view of the
digestibility, olive oil is the best one between
all other oils: if we consider equal to 100 the
digestibility of the olive oil, the sunflower-seed
oil turns out to be 83, the peanuts oil comes down
to 81 and maize oil arrives only to 36.
Its caloric value is very high: 900 calories for
100 grams. Caloric value of olives is 142 calories
for 100 gr. of edible part of green olives and 234
for the black ones.
