On January 30, the 2015 edi­tion of Enoliexpo Adriatica Fair was inau­gu­rated in Fermo. During the Fair the tech­no­log­i­cal devel­op­ments in the field of oenol­ogy and olive milling were dis­cussed.

During the open­ing con­fer­ence of the event, Prof. Maurizio Servili, from the University of Perugia, pre­sented the results of research con­ducted over the past five years on the chem­istry makeup of 5,000 sam­ples of Italian extra vir­gin olive oils.

The median per­cent­age of oleic acid com­pared to the total fatty acid com­po­si­tion was 75 per­cent; the con­tent of phe­no­lic com­pounds of the ana­lyzed oils was greater than 300 mg/Kg, with a median of 452 mg/Kg; the median value of α‑tocopherol was 209 mg/Kg.

From the results, the researchers said, we can deduce the strong link between the chem­i­cal com­pounds and the olive cul­ti­vars and pro­duc­tion areas. The sen­sory char­ac­ter­is­tics of some Italian EVOOs can be con­sid­ered unique and dif­fi­cult to repro­duce in other olive-grow­ing areas in the world,” Servili said, because of their high con­tent of oleic acid and the pres­ence of phe­no­lic com­pounds such as α toco­pherol and squalene.”

The Prof. Servili’s research was con­ducted with the col­lab­o­ra­tion of Unaprol (the National Union of Associations of olive pro­duc­ers) which is also help­ing to develop new meth­ods in oil extrac­tion tech­nol­ogy and sus­tain­abil­ity. (During milling only a small per­cent­age of olives are extracted and exploited — the oil never exceeds 20 per­cent of the total mass — while the rest of it is dis­posed off.)

The increase in the prof­itabil­ity of the Italian olive oil sec­tor,” said David Granieri, Unaprol President, said dur­ing the con­fer­ence, can improve thanks to the stud­ies sup­ported by Unaprol, through a more ratio­nal and com­plete use of the olives in milling, by gen­er­at­ing new eco­nomic oppor­tu­ni­ties in the sup­ply chain and related indus­tries con­nected to it.”

Unaprol invested over €1 mil­lion in sci­en­tific research in the last three years, Granieri stated.
