Provedor de dados: 86
Autores: Telis,Vânia Regina Nicoletti; Lourençon,Vânia Araújo; Gabas,Ana Lúcia; Telis-Romero,Javier.
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...

Provedor de dados: 31
Autores: Sottomayor,   Miguel; Souza Monteiro,   Diogo M.; Teixeira,   Mario Sergio.
The Portuguese olive oil market had a remarkable development in recent years. Production is rising steadily is response to a EU program supporting a renewal of olive groves. Moreover there is a proliferation of national brands and private labels. These are often associated to regional collective labels or to organic production. The aim of our research is to determine how consumers value these nested names or co-brands. We conducted a pilot survey on a convenience sample of 103 consumers in the Oporto and Lisbon metropolitan areas as well in a rural area. Our results reveal some contradictions, for instance while origin is an important purchasing criteria, few PDO olive oils are recognized. Moreover, only 25% of respondents identify organic olive oils sold...

Explaining German imports of olive oil: evidence from a gravity model
Provedor de dados: 31
Autores: Kavallari,   Aikaterini; Maas,   Sarah; Schmitz,   P. Michael.
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...

Exploring Japanese olive oil consumer behavior
Provedor de dados: 31
Autores: Mtimet,   Nadhem; Kashiwagi,   Kenichi; Zaibet,   Lokman; Masakazu,   N.
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...

Olive oils protected by the EU geographical indications: creation and distribution of the value-adding within supply chains
Provedor de dados: 31
Autores: Roselli,   Luigi; Casieri,   Arturo; De Gennaro,   Bernardo; Medicamento,   Umberto.
The world olive oil market is characterized by a growing price competition on the supply side. Economy of scales and low production costs from both traditional and more recent producing Countries determine an increasing pressure on European Union (EU) olive farmers that suffer lower revenues. Product differentiation, driven by higher quality and consumer expectations, is one of the most powerful competitive strategies that EU farmers may adopt to face this challenge. Geographical indications established by the EU (PDO and PGI) can be successful marketing levers to ensure olive oil differentiation based on high quality standards and geographical origin of production. These EU quality certification schemes were designed to respond to consumer demand, to...

Evolution of olive oil import demand structures in nonproducing countries: the cases of Germany and the UK
Provedor de dados: 31
Autores: Kavallari,   Aikaterini; Maas,   Sarah; Schmitz,   P. Michael.
Consumption patterns of olive oil have changed over recent years influencing the supply chain. The consumption has increased in countries where olive oil is not part of the traditional diet as for example Germany and the UK, where the average consumption grew by 11 and 13% respectively during the period 1995-2003. The opening of new non-traditional markets has shifted exports and re-structured the supply chain. Mediterranean countries have been the traditional suppliers of olive oil with the EU Mediterranean Member States being the main exporters and with the non-EU Mediterranean countries trying to gain market shares in the EU markets in an attempt to benefit from the preferential access due to the Barcelona Agreement. This paper tries to identify which...

Autores: Clapan,   Carmen; Periklis,   Drakos; Gadanakis,   Yiorgos; Baourakis,   George.
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...

Provedor de dados: 31
Autores: Chan-Halbrendt,   Catherine; Zhllima,   Edvin; Sisior,   Gwendalyn; Imami,   Drini; Leonetti,   Luciano.
Increase in urban middle income consumers along with consolidation of the retail sector has created changes in olive oil consumption preferences in Albania. The objective of this study is to inform stakeholders in the olive oil industry about consumer preferences. A Conjoint Choice Experiment (CCE) was used to design the survey and latent class approach used to analyze the data. The results show a strong preference for domestic olive oil and small niche markets that cater to specific consumers. The study also shows a gap between preference and reality that needs to be addressed by the stakeholders in the olive oil industry.

The impact of the government policies and incentives to promote the export of agricultural products in Tunisia: case of olive oil
Provedor de dados: 31
Autores: Larbi,   Walid; Chymis,   Athanasios G.
The agricultural sector is very important for the Tunisian economy as it absorbs 10% of the total investment, generates 12% of the Gross Domestic Product (2002-2006) and employs 16% of the total labor force while the agro food exports represent 10% of the total export. The aim of this article is to review: a) the agreements related to the export of the olive oil between Tunisia and the European Union (EU) and b) the agricultural policies and incentives enforced by the government to increase the export of olive oil. For the above mentioned aims, we obtained and analyzed data from the Ministry of Agriculture in order to analyze them and find the policies and incentives that help to increase the export of olive oil.

The EU demand for imports of virgin olive oil
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria.
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...

Product Attribute Saliency and Region of Origin: Some Empirical Evidence from Portugal
Provedor de dados: 31
Autores: Santos,   J. Freitas; Ribeiro,   J. Cadima.
This paper empirically investigates the extent to which consumer preferences may act as promoters of regional products. Three products are studied in terms of the importance consumers attach to various product attributes with particular emphasis on region of origin information. The estimation of a hedonic price function, which relates the price of Portuguese regional products to its various attributes, provided empirical support to the hypothesis that region of origin matters to consumers. The study shows that wine, olive oil and cheese from some regions of origin have a significant impact on price. Particularly, some regions of origin are expected to have price premiums, while others are expected to have discounts.

3D front-face fluorescence spectroscopy for characterization of extra virgin olive oil and olive oil according to the spectral pattern
Provedor de dados: 111
Autores: Lleó, Lourdes; Hernández-Sánchez, Natalia; Ammari, Faten; Roger, Jean-Michel.
3D front-face fluorescence spectroscopy and principal component analysis (PCA) were used to differentiate between Extra Virgin Olive (EVOO) and Olive Oil (OO). The results show that 3D front-face fluorescence could be an effective tool to characterize EVOO and OO. Fourteen samples of olive oils were acquired directly from producers and from retail markets and their 3D fluorescence spectra were measured and analyzed. The first principal component of the PCA model retained the most important variability as a combination of freshness due to the presence of antioxidant compounds and chlorophyll; and of oxidation stage due to the presence of oxidation products. Olive oil samples presented different spectral pattern providing different scores for EVOO and OO in...

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...

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...

Monounsaturated fats and immune function
Provedor de dados: 56
Autores: Yaqoob,P.
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...

How does the added fat source affect sensory quality of sheep and goat pâtés?
Provedor de dados: 65
Autores: Rodrigues,Sandra; Almeida,Samanta; Pereira,Etelvina; Teixeira,Alfredo.
ABSTRACT:  Sensory quality of sheep and goat pâtés with different sources and percentage of fat (10% or 30%, and pork belly or olive oil) were evaluated. A trained taste panel performed sensory analysis and consumers were consulted to perceive their preferences. Generalised Procrustes Analysis was used to test the differences found by panellists. Panellists were able to find sensory differences between sheep and goat pâtés, and also fat percentages. Goat pâtés had higher values of juiciness and sheep pâtés had higher values of taste intensity. Ten percent pork belly fat pâtés had the highest values of colour and cohesiveness attributes and also aroma intensity, while 30% olive oil pâtés had the highest values of texture attributes, except cohesiveness....
