The label authentication of monovarietal extra virgin olives is great relevance from a socio-economical point view. This work aims to gain insights into the prediction varietal origin olive oil (EVOO) samples obtained single cultivars, French cultivars Olivière, Salonenque, and Tanche Portuguese Blanqueta, Carrasquenha, Galega Vulgar, collected in 2016–2017 2017–2018 harvest seasons. To pursue ...

opening frontiers has led in the last two decades to a massive migration of romanians to spain and italy, two countries known to have large areas planted with olives. romania owns large areas planted with ash forests. because of cross-reactivity between these two trees belonging to the oleaceae family and the big allergenic potential of olive pollens, after a number of years of residence in the...

Coratina cultivar-based olives are very common among 100% Italian extra virgin olive oils (EVOOs). Often, the very spicy character of this cultivar, mostly due to the high polyphenols concentration, requires blending with other "sweetener" oils. In this work, monovarietal EVOO samples from the Coratina cultivar (Apulia, Italy) were investigated and compared with monovarietal EVOO from native or...

Maslinic acid (MA) is a natural triterpene present in high concentrations in the waxy skin of olives. We have previously reported that MA induces apoptotic cell death via the mitochondrial apoptotic pathway in HT29 colon cancer cells. Here, we show that MA induces apoptosis in Caco-2 colon cancer cells via the extrinsic apoptotic pathway in a dose-dependent manner. MA triggered a series of effe...

Plant lipoxygenases (LOXs) are a class of widespread dioxygenases catalysing the hydroperoxidation of polyunsaturated fatty acids. Although multiple isoforms of LOX have been detected in a wide range of plants, their physiological roles remain to be clarified. With the aim to clarify the occurrence of LOXs in olives and their contribution to the elaboration of the olive oil aroma, we cloned and...

Olives come in a number of external and internal varieties. The Shengeh kind, which is available three colours—green, brown, black—was chosen at random by the researchers to ensure that sample was diverse. To avoid discoloration throughout experiment, 150 healthy olives were harvested stored correctly. These had not been subjected any harm, such as crushing or milling. particular kind kept chil...

In this work, in experimental phase, the digital elevations models (DEMs) appear as a fundamental tool for studying erosion of the land in a concrete zone of agricultural production, olives production. Collected data from the zone of study in different campaigns are used to determine possible variations in the orography of the land. GPS is the used tool to measuring coordinates of points in the...

In the present work the use of treated wastewater (TWW) to irrigate olive plants was monitored. This type of water is characterized by high salinity and retains a substantial amount of trace elements, organic and metallic compounds that can be transferred into the soil and into the plants and fruits. In order to evaluate the impact of TWW on the overall quality of the oils, the time of contact ...

During the extraction, a portion of oil remains trapped inside the cells and its release requires the degradation of the walls and cell membranes, especially when the fruits have not reached a maximum maturity which is likely to cause an optimal embrittlement of the parietal structures and cell membrane. This can be done by specific enzymes necessary for the degradation of various cellular barr...
