OLIO di annata.

Scoperto olio di 8.000 anni fa, in Galilea.

Uno scavo ufficiale delle autorità Israeliane per l'archeologia ha portato alla scoperta di quello che  - per il momento, almeno - è il più antico olio d'oliva d'Israele e forse di tutto il Medio Oriente.
I lavori sono scavi di salvataggio nel corso della costruzione di un'autostrada, la 79. 
I rsti sono stati datati ed analizzati: risalgono al 6.000 a.C. (il Calcolitico, o Età del Rame).
Non è possibile stabilire se fino da allora l'olio fosse parte integrante della dieta (anche se frequenti citazioni della Bibbia lasciano intendere che l'olio, insieme al grano ed all'uva ne erano i fondamenti). Scientificamente, si sa che l'olio poteva essere usato per l'illuminazione e perfino per piccoli forni fusori.

8,000 year old olive oil discovered in Galilee

Remains of 8,000-year-old olive oil were uncovered in the lower Galilee during an Israel Antiquities Authority (IAA) excavation.

The rare findings, the IAA explained, are the oldest evidence of olive oil use in the land of Israel and perhaps even in the entire Middle East. 
An article in the Israel Journal of Plant Sciences presents research conducted by Dr. Yaniv Milevski and Nimrod Getzov in a salvage excavation the IAA conducted in Ein Zippori between 2011-2013, prior to the widening of Highway 79 by the National Roads Company.

The excavation found evidence of olive oil being used in the 6th millennium BC. The IAA researchers took systematically sampled the pottery found in the dig to find out what was stored in them and what uses inhabitants made of them. The IAA researchers, along with Dr. Dvory Namdar from the Institute of Earth Sciences at the Hebrew University in Jerusalem, took a small piece of the earthenware and used chemical methods of extraction and identification to examine attached organic remains, which were dated to the ancient Chalcolithic period, also known as the Copper Age.

A comparison of the extraction results from the ancient pottery with those of one-year-old modern-day olive oil showed great similarity between the two samples, which shows of particularly high level of preservation of the ancient oil that survived in a very similar composition to the original.

"Past underwater archaeological digs led by Dr. Ehud Galili off the coast of Kafr Samir south of Haifa found remnants of olive oil production from that period but now, in Zippori, we have found the first evidence of the oil being used," the researchers wrote. "Along with the discovery from Kafr Samir, this is the earliest evidence of olive oil manufacturing in Israel. "Olive oil was probably a part of the diet back then, and may have been used for lighting
Even though we can't determine this with certainty, this might be a kind of olives that were domesticated and added to other field crops like cereals and legumes. Since then and to this very day, the Mediterranean economy is based on oil, cereals and grapes, three crops mentioned frequently in the Bible."
