Summary of "A preliminary study on the authentication and traceability of extra virgin olive oil made from Taggiasca olives by means of trace and ultra-trace elements distribution."

Extra virgin olive oil (EVO) is among the most counterfeit foodstuffs in the present market. The Italian production is with no doubt one of the most valuable and therefore mostly counterfeit, due to the difficulty in checking the geographic provenance of olives. In order to provide a way for verifying the provenance of EVO, the role of microelements and, in particular, of lanthanides in the oil production chain has been studied. The distribution of lanthanides as determined by means of ICP-MS analysis appeared to provide a good tool for tracing the EVO production chain. Lanthanides and other microelements were then used for distinguishing a particularly prised EVO production from Liguria (northwestern Italy) made from Taggiasca olive variety, verifying that this production can be easily authenticated on the base of these chemical descriptors.

Medical and Biotech [MESH] Definitions

A group of islands in the Lesser Antilles in the West Indies, the three main islands being St. Croix, St. Thomas, and St. John. The capital is Charlotte Amalie. The Virgin Islands were discovered by Columbus in 1493. Before 1917 the U.S. Virgin Islands were held by the Danish and called the Danish West Indies but the name was changed when the United States acquired them by purchase. Virgin refers to the fact that Columbus made his discovery on St. Ursula's day - virgins being her legendary companions - or to the resemblance of the chain of islands to a procession of nuns or virgins. (From Webster's New Geographical Dictionary, 1988, p1305 & Room, Brewer's Dictionary of Names, 1992, p577)
