The objective of this work was to determine the most appropriated chemical treatment to be used to dry grapes cv. Rubi for raisin production. Drying curves for convective drying with air at 50ºC, in a tray drier, were obtained for grapes submitted to chemical pretreatments with different concentrations of potassium carbonate and olive oil, and different dipping times, according to factorial designs. Convective drying curves were also obtained for grapes pretreated in aqueous suspensions of soybean lecithin, at varied lecithin concentrations and dipping times. Page model was adjusted to the experimental drying curves, and the calculated drying times showed that the best pretreatment consisted in dipping grapes for 2 minutes in a 5% olive oil and 6% K2CO3... |

In this study the case of olive oil imports of Germany is examined since olive oil is a traditional Mediterranean commodity and Germany is the biggest importer in the EU. A gravity model has been employed so as to analyse those factors that explain the German imports of olive oil that were identified in a preceding analysis of the German olive oil supply chain. The results of two random-effects models corrected for serial correlation and heteroskedasticity suggest that being a Mediterranean Partner country of the EU has the highest impact on trade flows to Germany, thus supporting further Euromediterranean trade integration. The level of trade to Germany is positively related to existence of direct marketing channels and to tourism implying that these... |

During the last two decades, olive oil consumption in Japan is showing an increasing trend due to dietary and health concerns. Traditional olive oil producer and exporter countries such as Italy, Spain and Tunisia have interest to reinforce and to increase their penetration in the Japanese market. This study examines Japanese olive oil consumer behaviour by the use of the conjoint analysis technique. Five attributes have been chosen to design the experiment: region of origin, price, olive oil type, taste and colour. Two models have been estimated where the price variable was introduced in its discrete form in the first model and in its linear and quadratic from in the second model. In a second step, consumer segmentation was undertaken based on consumption... |

Phenolic compounds have shown to inhibit LDL oxidation in vitro and ex vivo; however, they are hydrosoluble compounds while LDL is a lipoprotein. Analysis of phenolic compounds in LDLs by HPLC is necessary to demonstrate their binding capacity to lipoproteins. We developed and validated a solid phase extraction method (SPE) that allowed us the purification of LDL samples and their analysis by HPLC. This methodology allowed us to demonstrate the in vitro binding capacity of tyrosol, one of the main phenolic compounds in olive oil, to LDL. In the intervention dietary study with volunteers, food rich in phenolic compounds affected LDL composition. Changes in LDL phenolics composition are not observed after the short-term ingestion of food rich in phenolic... |

Animal studies suggest that olive oil is capable of modulating functions of cells of the immune system in a manner similar to, albeit weaker than, fish oils. There is some evidence that the effects of olive oil on immune function in animal studies are due to oleic acid rather than to trace elements or antioxidants. Importantly, several studies have demonstrated effects of oleic acid-containing diets on in vivo immune responses. In contrast, consumption of a monounsaturated fatty acid (MUFA)-rich diet by humans does not appear to bring about a general suppression of immune cell functions. The effects of this diet in humans are limited to decreasing aspects of adhesion of peripheral blood mononuclear cells, although there are trends towards decreases in... |

This paper has analysed the import demand for virgin olive oil in the EU and more precisely in the Italian market, as it concentrates more than 80% of EU imports, aiming to determine the relative position of Mediterranean EU and non-EU countries exports and their degree of substitutability or complementarity. The methodology used is based on the specification of a Threshold Almost Ideal Demand System in which special attention has been paid to the stochastic properties of the series involved. In an empirical context, the paper has aimed to provide a set of import demand elasticities that can be useful in trade models. Results point to Spain as the leader in the Italian virgin olive oil market. It is expected that this position will be maintained in the... |

Abstract: To date, most of studies have only focused on metabolic effects of dietary oils while recent evidence proposes that they can influence kidneys structure. Therefore, the aim of this study was to evaluate the impact of long-term consumption of olive, cottonseed and sesame oils on renal morphology in rats. 70 male Wistar rats randomly assigned into seven equal groups and treated with standard diet (control), the standard diet enriched with 10% or 20% (W/W) of either olive oil (OLI10%, OLI20%), cottonseed oil (COT10%, COT20%) or sesame oil (SES10%, SES20%) for 5 months. Quantitative features of the kidney including kidney and cortex volumes and the number of glomeruli were analyzed stereologically. Moreover, kidney sections histologically were... |

This paper examines and analyzes the impacts of the reformed CAP as well as the decisions of the new round of negotiations for the olive oil and cotton sectors in the European Union. The aim of this study is to estimate the changes in supply (agricultural supply plus intermediate demand and final production), demand (consumption), price and stock formation (import, export, beginning and ending stocks, national price formation) for both the olive oil and cotton sectors. The model designed for this purpose is partial equilibrium and policy oriented. The objectives of this model are to estimate changes in the production and consumption of the two products concerned, to determine how the reformed Common Agricultural Policy (CAP) and the new round of... |
