Olive oil is obtained from the fruit of the olive tree by manual or mechanical means.
The olive oil is a product, which is natural and
can be consumed as soon as the procedure of its collection has been
completed.
It is almost totally absorbed by the organism
(98%) and it gives the same number of calories as all the other natural
oils, which are 9.3 for each gram.
It comprises the basic source of fats in Mediterranean Nutrition.
The fats of vegetable origin contain more
polyunsaturated and monounsaturated fat acids and are considered healthy
since they do not contain any cholesterol.
Different types of olive oil can be found
with more or less processing such as green olive oil, organic olive oil,
and aromatic olive oil.
Here are a few tips on how to savor the bold and subtle differences among the Tunisian olive oils.
Examine the color. The two most important factors
influencing the color of the finished oil are the variety of olive and
its maturity at the time of harvest. Early-picked olives yield dark,
greener oil, while ripe olives produce an oil that is lighter and more
yellow in color.
Taste the oil either by dipping a piece of white
bread into it or by drawing a teaspoonful of oil quickly into the mouth,
mixing it with air to register the sensation of all the nuances of
flavor. Between sips, cleanse the palate with a piece of crisp apple,
fresh sliced fennel or unflavored sparkling water.
