From the cultivation of olives yields a drupe that, subject to crushing and separation from the vegetation water and pomace, oil produces only fat Food derived from a fruit . From what we understand as the quality of the plant and consequently affect the characteristics of the drupe of the finished product
In areas of our planet to warm-temperate climate, you can see a similar vegetation: plants belonging to the genus Olea are very common in these areas and of these, the most important species is the ' Olea europea, highly popular in the Mediterranean and beyond. This species over the centuries has played vital to humans.
The first written documents on the cultivation Olive, are the tablets with cuneiform writing of the mid-third millennium, found at Ebla, protosiriana center of civilization in northern Syria, an area in which there were vast expanses of forest type of this species, which is believed to have originated domestic varieties. But the stones were found in the remains of human settlements, evidence of the presence of an ancestor of the olive in the Paleolithic period.
The olive tree home from the Middle East would spread to all parts of the world where the climate has allowed its cultivation.
In Sardinia, the wild form is ancient, in fact there are olive trees that date back to Nuragic period, from which oil is extracted from the fruits with special equipment and environments, as found in the palace in Barumini and beyond. While the spread of the domesticated form was made by the peoples of Minoan origin.
From here onwards there has been an alternation of periods of exploitation and abandonment of this crop, which is closely linked to historical events.
In the Roman period witnessed the development of important areas, olive grove, especially in central and southern part of the island, it appears the first presses to extract oil. With the fall of Romano, stops the development of olive until the period of influence of Pisa, from which come several documents.
Then we have another period of stagnation until the first half of the seventeenth century with the spread of English law that defines the distribution areas of olive cultivation, is still present. During this period, spread new varieties, new mills for extracting oil and laws for the protection of olive trees.
The Piedmontese government is an improvement in the technique of cultivation and production.
During the early part of 1800 the first plants appear on the island for the industrial extraction of oil from pomace, and finally to technological improvements in the Second World War, accentuated after the '60s and '70s, with more attention to the whole production process, especially in the qualitative and quantitative aspects, in order to obtain a product more valuable.
oil has no known only important in terms of food, but its uses were many and is still present in many aspects of human life.
