The last message on the adulteration of extra virgin olive oil mixed with deodorized comes ARPA of Ascoli Piceno, who analyzed 68 samples of extra-virgin (33 mills levied in the Marche and 35 bottles purchased at retail). The final verdict is striking:approximately one third of the extra-virgin bought in supermarkets can be considered outside the norm for the excessive presence of alkyl esters.
The anomalous presence of this substance leaves assume a fraud against the consumer because it means that the olives are crushed before being pressed, fermented, or dented.When the olives are spoiled little extra-virgin olive oil has a content of alkyl esters of less than 75 milligrams per kilogram, when many (as the olives have been amassed for days before being pressed, it is collected from the ground, because they are preserved in closed containers or in plastic bags …) the presence of alkyl esters greatly increases, the oil begins to smell bad and can not be sold as extra virgin. Now it deodorize clever producers in a “mild” (so as to leave no visible signs of treatment) and add extra-virgin true. The magical effect has worked for years, up to when the controllers have established that the excessive presence of alkyl esters can be considered an index of fraud.
“The average concentration in oil samples coming directly from the mill was 15 milligrams per kilogram – says Ernesto Corradetti dell’Arpam of Ascoli Piceno – while in bottles bought at the supermarket level is ten times higher.” These figures are exaggerated, because in February should be in place new EU standards, and the oil can not contain more than 75 milligrams per kilogram of alkyl esters as proposed by the International Oleic Council.
The element that should generate some suspicion on the genuineness of the oil is price. When on the shelves of some supermarkets are bottles of extra-virgin at the price of 2.5-3.0 € / l is natural to ask how you can get to these levels.The price is amazing considering that the wholesale price list for November indicate a minimum amount of 2.05 € / l for oil Spanish, Tunisian and Greek. To this figure must be added the costs of transportation, processing and bottling over the edge of the vendor and the end rsulta difficult to make ends meet.
“It’s worth remembering – reminds Uploaded Director Louis website Natural theater - that just over a year ago has sold DìperDì GS-extra-virgin Nature Company Portaro in a glass bottle at the incredible price of 1.99 € / l ‘. Perhaps it is not to say that the oils with random values out of the norm in Ascoli Piceno analyzed fall within a range which these price ranges.
