Determination of the cultivar and aging of Sicilian olive oils using HPLC-MS and linear discriminant analysis

2010

A large number of certified samples (84) of Sicilian olive oils arising from the eight cultivars most represented in Sicily (Biancolilla, Cerasuola, Moresca, Nocellara del Belice, Nocellara Etnea, Oglialora Messinese, Brandofino and Tonda Iblea) have been collected and analyzed by HPLC/MS using an atmospheric pressure chemical ionization (APCI) source. The sample preparation is very simple; in fact, the oil samples are diluted without any chemical derivatization. A following statistical data treatment by general discriminant analysis (GDA) allows the determination of the olive oil cultivar. Furthermore, changes in the composition of glyceridic components of the olive oils lead to easy discr…

Fermentation profiles of Manzanilla-Aloreña cracked green table olives in different chloride salt mixtures.

2010

NaCl plays an important role in table olive processing affecting the flavour and microbiological stability of the final product. However, consumers demand foods low in sodium, which makes necessary to decrease levels of this mineral in fruits. In this work, the effects of diverse mixtures of NaCl, CaCl2 and KCl on the fermentation profiles of cracked directly brined Manzanilla-Aloreña olives, were studied by means of response surface methodology based in a simplex lattice mixture design with constrains. All salt combinations led to lactic acid processes. The growth of Enterobacteriaceae populations was always limited and partially inhibited by the presence of CaCl2. Only time to reach half …

Evaluation of different mechanical fruit harvesting systems and oil quality in very large size olive trees

2014

In 2006 and 2009, trials were carried out in the Apulia region in Southern Italy to evalu-ate the possibility of mechanizing olive harvesting in groves of old and very large trees. The trees belonged to the cultivars ‘Cellina di Nardò’ and ‘Ogliarola Salentina’. They were 60-100 years old and 7-9 m tall with a canopy volume of 140-360 m3. In the first half of November 2006, with a mechanical beater mounted on a tractor plus hand-held pneumatic combs, the harvesting yield was close to 90% of the total olives present in the canopy, and the harvesting working productivity was around 60 kg of harvested olives h-1 worker-1. With a self-propelled shaker attached to the main branches the harvestin…

Trasformare il Moderno. L’architettura della clinica Santa Barbara per la città ANIC ENI di Gela

2018

L’esperienza della trasformazione della clinica Santa Barbara ha messo in evidenza alcuni temi specifici che riguardano il senso del progetto contemporaneo entro le dinamiche divergenti e rizomatiche che caratterizzano il nostro tempo. Dinamiche che ci obbligano a guardare al progetto di architettura come una pratica curatoriale, estesa nel tempo e nello spazio, che può tendere all’unità (anche senza raggiungerla) attraverso azioni prolungate di manutenzione permanente. Pratiche che non hanno nulla a che fare con il facility management ma che riguardano, piuttosto, un paziente lavoro di accumulazione attraverso sfere di azione differenti.E’ possibile dunque, in conclusione enucleare alcuni …

Yeast biota of naturally fermented black olives in different brines made from cv. Gemlik grown in various districts of the Cukurova region of Turkey.

2015

In this study, the yeast microbiota of naturally fermented black olives made from cv. Gemlik, grown in three different districts of the Cukurova region of Turkey, were investigated. Fermentations were conducted for 180days in three different brines, including NaCl 10% w/v, NaCl 8% w/v and NaCl 8% w/v added with glucose 0.5%. In total, 223 yeasts were isolated and then identified by PCR-RFLP analysis of the 5.8S ITS rRNA region and sequence information for the D1/D2 domains of the 26S rRNA gene. A broad range of yeast biodiversity was identified, including eight genera and nine species. Candida boidinii (41%), Wickerhamomyces anomalus (32%) and Saccharomyces sp. (18%) were predominant yeasts…

Flora Ossette’s ‘feminist visibility’ in her translation of Olive Schreiner’s Woman and Labour

2011

The visibility of the translator has become a pervasive topic of discussion in translation studies ever since it was explicitly approached by Lawrence Venuti in his well known 1995 The Translator’s Invisibility. In Flora Ossette’s translation into Spanish of Woman and Labour by Olive Schreiner we cannot only appreciate the voice of the “implicit translator” (Hermans 1996) but also the “explicit” voice. Indeed, the translator actively participates in the text by adding, omitting, reorganizing or emphasizing Schreiner’s ideas. Moreover, led on by the feminist ideals shared by both writer and translator, no less than by her fervent admiration for the South African authoress, she actually becom…

Olive oil intake and cancer risk: A systematic review and meta-analysis

2022

Background Research evidence has established the beneficial effects of diet in cancer prevention; various epidemiological studies have suggested that olive oil component could play a role in decreasing cancer risk. This systematic review and meta-analysis aims to investigate the association between olive oil consumption, cancer risk and prognosis. Methods A systematic search was conducted in PubMed, EMBASE and Google Scholar databases (end-of-search: May 10, 2020). Pooled relative risk (RR) and 95% confidence intervals (95% CIs) were estimated with random-effects (DerSimonian-Laird) models. Subgroup analyses, sensitivity analyses and meta-regression analysis were also performed. Results 45…

Influence of Variety and Maturity Stage on Sterolic Composition of Virgin Olive Oil from Central-Western Sicily

Olive oil is one of the most important food products throughout the Mediterranean Basin due to its high nutritional and dietetic value. In recent years, there has been increased interest in the sterols of olive oil for their health benefts and their importance to virgin olive oil quality regulation. The impact of sterols on the human health is proved by several studies, showing that a suffcient quantity of β-sitosterol inhibits the intestinal absorption of LDL-cholesterol. In olive oil the phytosterol concentration ranges from 800 to 2600 mg kg-1. Sterol esters evaluation has been proposed as useful parameter in studies related to varietal and geographical discrimination. Cultivar and matur…

On the influences of vegetation biomass on COSMO-Skymed X-band

2011

The knowledge of spatial and temporal variability of land cover is important to manage water resources for yield forecasting, water stress prediction, irrigation water management and flood protection. Cloud cover dramatically reduces the temporal resolution of optical data thus limiting their operational use; in addition, the spatial resolution is often inadequate for applications in heterogeneous areas. On the other hand, algorithms based on Synthetic Aperture Radar (SAR) implemented to retrieve vegetation parameters are not yet fully validated. New SAR missions (COSMO-Skymed and Terrasar-X) may represent a suitable source of data for operational uses due to the high spatial and temporal r…
