Cinnamic acid, ethanol and temperature interaction on coumarate decarboxylase activity and the relative expression of the putative cd gene in D. bruxellensis
Provedor de dados: 69
Autores: Ganga,María Angélica; Salinas,Francisco; Ravanal,Cristina; García,Verónica; Carrasco,Carolina; Martínez,Claudio; Saavedra,Jorge.
Dekkera bruxellensis is one of the main contaminating yeasts in wine due to its ability to metabolize cinnamic acids into volatile phenols. This yeast metabolizes p-coumaric acid into 4-vinylphenol through a coumarate decarboxylase (CD) and then transforms it into to 4-ethylphenol (EF) through a vinylphenol reductase. In this work we investigated the influence of the interaction between the concentration of p-coumaric acid, ferulic acid and ethanol as well as growth temperature on the production of CD activity and the expression of a putative gene that codes for this enzymatic activity. For this, a Box Behnken experimental design was used. The concentration of p-coumaric acid (5-26 ppm) and ferulic acid (3-9 ppm) alone did not show any significant effect...

Production of Rhodotorula glutinis: a yeast that secretes alpha-L-arabinofuranosidase
Provedor de dados: 69
Autores: Martínez,Claudio; Gertosio,Cecilia; Labbe,Angelica; Pérez,Rafael; Ganga,Maria Angélica.
Rhodotorula glutinis is a yeast that secretes the enzyme alpha-L-arabinofuranosidase (E.C. 3.2.1.55) into the culture medium and thus has an interesting biotechnological potential. To determine improved culture conditions of this organism, different factors of the culture media were evaluated such as the use of peptone as nitrogen source, salts composition, pH and growth temperature. Likewise, beet molasses and beet cosette were tested as industrial carbon sources to induce the production of the enzyme and how they influence the yeast growth. Based on these studies a culture medium is proposed for growth of this yeast in a continuous system. By assaying different dilution rates an average specific activity for the enzyme of 82.4 U/mg of protein was obtained.

An experimental study of wine consumers’ willingness to pay for environmental characteristics
Provedor de dados: 31
Autores: Bazoche,   P.; Deola,   C.; Soler,   Louis-Georges.
The reduction of pesticides use is becoming a priority for the public authorities in many countries. We conducted an experiment with wine consumers to see whether end-consumers value the dissemination of information about environmentally-friendly production practices. The experiment was devised to (i) evaluate whether there is a premium for environmentally-friendly wines, (ii) determine whether or not consumers are sensitive to label owners who implement and guarantee the environmental actions, (iii) and assess the impact of public messages about the consequences of pesticide use. Some 139 participants were divided randomly into two groups. One group had no specific information about the current state of pesticide use in farming. The other group was given...

Does Knowledge-Based Economy Speaks to Consumers? A French Case Study with Respect to Food Products
Provedor de dados: 31
Autores: Giraud,   Georges; Lebecque,   Annick; Amblard,   Corinne; Bord,   Cecile; Sulmont-Rosse,   Claire; Lefur,   Yves.
The paradigm of knowledge-based economy states that information asymmetry between consumers and producers will be reduced thanks to information availability and dissemination through the Internet or other media channels. Conversely to this statement, some published articles shown that knowledge-based economy reinforces the information asymmetry between experts and novices among the consumers (Hogg et al., 2007; Gregan-Paxton &amp; Roedder-John, 1997; Alba &amp; Hutchinson, 1987). Accordingly, we will consider the non homogeneity of consumers and will try to identify and qualify the differences between several groups of respondents regarding two food items by means of a k-means clustering applied to a knowledge-oriented questionnaire.

A Methodology for Evaluating How Product Characteristics Impact Choice in Retail Settings with Many Zero Observations: An Application to Restaurant Wine Purchase
Provedor de dados: 31
Autores: Durham,   Catherine A.; Pardoe,   Iain; Vega-H,   Esteban.
An approach is developed to examine the impact of product characteristics on choice using a quantity-dependent hedonic model with retail panel data. Since panel data for individual products from retail settings can include a large number of zero sales, a modification of the zero-inflated Poisson (ZIP) regression model is proposed for estimation. Results for this model compare favorably to results for alternative hurdle and negative binomial models. An application of this methodology to restaurant wine sales produces useful results regarding sensory characteristics, price, and origin/varietal information.

COMPETITIVENESS OF MILK AND WINE PRODUCTION AND PROCESSING IN ALBANIA
Provedor de dados: 31
Autores: Petrick,   Martin; Schreiber,   Catrin; Weingarten,   Peter.
This study provides an empirical assessment of the competitiveness of Albanian dairy and wine production, based on specifically collected survey data. For both product groups, the analysis is carried out on two levels: farm level production of raw material and processing and manufacturing of the final product in the food industry. In a third step, both levels are aggre-gated to analyse the competitiveness of the entire production chain for each product group. Overall, the wine sector appears in an economically more favourable situation than the milk sector. Although there is currently no relevant export of wine, there has been considerable in-vestment activity at the farm level and the harmonisation of quality standards with EU legislation is currently...

Solvency and Performance of French Wineries in Times of Declining Sales: Co‐operatives and Corporations
Provedor de dados: 31
Autores: Declerck,   Francis; Viviani,   Jean-Laurent.
The paper assesses the ability of French wineries to prevail over the crisis of French wine in the years 2000. Corporations are distinguished from co‐operatives: Over the 2000‐2006 period in spite of sales fluctuations, French wineries did not increase their financial debt level substantially. Such result supports the traditional static trade‐off theory (TOT). Co‐operatives were able to absorb part of the impact of the wine crisis at the expense of their members, in increasing account payables to member. Corporations have not increased trade account payables to vine growers. In the mid‐2000s, the French wine crisis has not been strong enough to shake the financial structure of cooperatives and corporations. But co‐operatives look more affected. However,...

CATCHING-UP TRAJECTORIES IN THE WINE SECTOR: A COMPARATIVE STUDY OF CHILE, ITALY AND SOUTH AFRICA
Provedor de dados: 31
Autores: Cusmano,   Lucia; Morrison,   Andrea; Rabellotti,   Roberta.
From a development perspective an investigation of the changes that have occurred in the wine industry is of particular interest because it provides evidence on how emerging economies have been able to acquire significant shares of the international market in a dynamic sector. Based on novel empirical evidence as well as secondary sources, this paper shows that emerging countries with diverse institutional models and innovation strategies, have been driving the process of technological modernization and product standardization. Newcomers in the wine sector have responded particularly effectively to changes in consumption habits, and in aligning emerging scientific approaches with institutional building efforts and successful marketing strategies.

Connecting Product Attributes with Emotional Benefits. Analysis of a Mediterranean product across consumer age segments
Provedor de dados: 31
Autores: Barrena Figueroa,   Ramo; Sanchez Garcia,   Mercedes.
Due to a high level of product substitution in the food market, it often proves difficult to strike a balance between supply and demand. This is especially true in sectors with a such high level of competition and product differentiation as the wine producing sector. Faced with the difficulty of differentiating the product in terms of its technical characteristics, quality and price, therefore, a useful alternative is to explore what consumers perceive to be its "emotional benefits", since these have been shown to have a decisive effect on consumer purchasing decisions. For marketing purposes, an understanding of how consumers' personality traits condition their choice of products can help manufacturers to improve their strategic positioning in the market....

Impact of the Administrative Regulations in the Wine Value Chain: The Spanish Case
Provedor de dados: 31
Autores: de Felipe,   Isabel; Briz,   Miguel; Briz,   Teresa.
The wine value chain is characterized by its traditional nature. The transformation of the raw material makes lasting products with a high added value, which entails large price differences between producers and consumers. Given the socioeconomic important of this sector, it has specially been taken into account by the administration, with a high level of intervention. There is an ample range of interventions, from a qualitative and from a quantitative point of view. The main objective of all these policies is the intention of controlling the supply and stimulating the demand. The impact of these measures is considered in the short term, to solve the surplus problems. However, at the long run, it has a negative impact. The new framework of the wine...

The purpose of this paper is to contribute to a better understanding of the role of relationships between stakeholders in the supply chain as a potential source of competitive advantage. In the case study, we focus on the wine industry in the Lazio Region (Italy). We observe a significant loss of competitiveness in this industry and we suggest that a higher level of communication and different coordination mechanisms among stakeholders could help in recovering a better market position. We focus on the linkages between farmers and the other food chain stakeholders through the perspective of Institutional Economics and Economics of Organization, in order to identify the key factors that determine the competitiveness of the supply chain’s product.

MEASURING THE ECONOMIC EFFECT OF GLOBAL WARMING ON VITICULTURE USING AUCTION, RETAIL AND WHOLESALE PRICES
Provedor de dados: 31
Autores: Ashenfelter,   Orley; Storchmann,   Karl.
In this paper we measure the effect of year to year changes in the weather on wine prices and winery revenue in the Mosel Valley in Germany in order to determine the effect that climate change is likely to have on the income of wine growers. A novel aspect of our analysis is that we compare the estimates based on auction, retail, and wholesale prices. Although auction prices are based on actual transactions, they provide a thick market only for high quality, expensive wines and may overestimate climate’s effect on farmer revenues. Wholesale prices, on the other hand, do provide broad coverage of all wines sold and probably come closest to representing the revenues of farmers. Overall, we estimate a 1°C increase in temperature would yield an increase in...

Autores: Masset,   Philippe; Weisskopf,   Jean-Philippe.
This paper uses auction hammer prices over the period 1996-2009, with a special emphasis on periods of economic downturns, to examine risk, return and diversification benefits of fine wine. Our research shows evidence that the wine market is heterogeneous with wine regions and price categories evolving differently in terms of volume and turnover. We construct wine indices for various wine regions and prices using repeat-sales regressions and find out that fine wine yields higher returns and has a lower volatility compared to stocks especially in times of economic crises. Forming portfolios for typical investors and taking risk aversion, different financial assets and various wine indices into consideration we confirm that the addition of wine to a...

A Hedonic Pricing Model for German Wine
Provedor de dados: 31
Autores: Schamel,   Guenter.
We develop a hedonic pricing model for German quality wine. Quality indicators for 4,141 wines are sensory awards received at the annual German wine competition and the legally required quality category as well as a set of control variables including regional origin, color, style, and their age at the time of judging. The data confirms that sensory quality awards have a significant and positive price impact. Moreover, we estimate significant relative differences between quality categories, growing regions and most of the control variables.

In this paper we analyse wine demand in Italy using microdata. Instead of estimating a traditional parametric model (like AIDS) we employed artificial neural networks (ANN) and evaluate the elasticities using two different methods, specific for the non parametric framework. We compared the performances of the two methods to estimate elasticities and put in evidence the relevance of some demographic variables together with the usual economic ones, explaining the consumer's behaviour.

Overall wine consumption in Spain is decreasing while, at the same time, Designation of Origin (DO) wine consumption is increasing gradually. This study examines Spanish DO wine consumer behaviour through stated preferences (SP) and revealed preferences (RP) data. Part-worth utilities are calculated and results from both analyses are compared to look for similarities and differences between what respondents say on surveys and what they really do on real purchases. Consumer segmentation is undertaken based on purchase frequencies. In a second step, we try to pool the two data sources in order to get more meaningful and robust results. Results indicate similarities in the consumer choice process when comparing the two data sources, especially for the...

How to Promote Quality Perception in Wine Markets: Brand Advertising or Geographical Indication?
Provedor de dados: 31
Autores: Yue,   Chengyan; Marette,   Stephan; Beghin,   John C.
In the context of the wine industry, we investigate producers' choice between geographical indications and brand advertising to convey information to consumers. Producers also decide whether or not to select an effort level for improving the quality of their products. We show that if this effort level is selected, a producer will prefer to rely on brand advertising for promoting its products and setting up its own reputation. Despite allowing the cost of promotion to be shared, a geographical indication does not sufficiently reward the effort to improve quality. Finally, the selection of both instruments by producers is examined.

The Contribution of the Grape and Wine Industry to Idaho’s Economy: Agribusiness and Tourism Impacts
Provedor de dados: 31
Autores: Foltz,   John C.; Woodall,   Stacie; Wandschneider,   Philip R.; Taylor,   R. Garth.
The impact of Idaho’s wine and grape industry was assessed as an agribusiness and as a tourist industry. Idaho’s grape and wine industry is in its infancy, with wine sales of $15 million from 15 wineries and growers cultivating about 1,000 acres, primarily in southwestern Idaho’s Canyon County. Synthesized output multipliers for wine tourism were virtually identical to the agribusiness output multipliers (1.86 and 2.10 for Canyon County and the state of Idaho, respectively). The wine and grape industry’s agribusiness impact is $15 million in sales and 120 jobs in Idaho, and $23 million and 140 jobs for Canyon County. In contrast, tourism expenditures stimulate other businesses in addition to the agribusiness linkages of grape and wine production. Thus,...

Wine tax reform: The impact of introducing a volumetric excise tax for wine
Provedor de dados: 31
Autores: Fogarty,   James Joseph; Jakeman,   Guy.
In addition to the GST, alcohol sold in Australia is subject to excise tax. Although both beer and spirits are subject to a volumetric excise tax, wine is subject to an additional value added tax known as the Wine Equalisation Tax (WET). The recent Henry tax review recommended substantial changes to Australian alcohol taxation policy. Here, the implications for the wine industry of the Henry tax review recommendations are explored using a computable general equilibrium model. The results show that: (i) replacement of the WET with a revenue neutral volumetric excise tax would have a small negative impact on the wine industry; (ii) removal of the WET rebate would have a substantial negative impact on small wineries; and (iii) applying a uniform alcohol tax...

WHEN DOES THE PRICE AFFECT THE TASTE? RESULTS FROM A WINE EXPERIMENT
Provedor de dados: 31
Autores: Almenberg,   Johan; Dreber,   Anna.
We designed an experiment that examines how knowledge about the price of a good, and the time at which the information is received, affects how the good is experienced. The good in question was wine, and the price was either high or low. Our results suggest that hosts offering wine to guests can safely reveal the price: much is gained if the wine is expensive, and little is lost if it is cheap. Disclosing the high price before tasting the wine produces considerably higher ratings, although only from women. Disclosing the low price, by contrast, does not result in lower ratings. Our finding indicates that price not only serves to clear markets, it also serves as a marketing tool; it influences expectations that in turn shape a consumer’s experience. In...

We examine British Columbia (BC) wine consumers’ valuation of wine imported from emerging suppliers (Argentina, Bulgaria, Chile, Croatia and Hungary) through the estimation of a hedonic price function. Retail sales data employed in this study comes from the BC Liquor Distribution Branch and covers weekly sales of table wine that was imported from all five countries into the province of British Columbia. The results indicate that the grape variety is an important factor influencing consumers’ willingness to pay. In particular, white and red wines from Chile are associated with larger price premia while wines from Argentina command a premium only among red wines. Wines from Bulgaria, Croatia and Hungary, although sold in large quantities in the BC market,...

Economic Hysteresis in Variety Selection
Provedor de dados: 31
Autores: Richards,   Timothy J.; Green,   Gareth P.
Investing in a new perennial crop variety involves an irreversible commitment of capital and generates an uncertain return stream.  As a result, the decision to adopt a new variety includes a significant real option value.  Waiting for returns to rise above this real option causes a delay in adoption because of economic hysteresis.  This study tests for hysteresis in the adoption of wine grape varieties using a sample of district-level data from the state of California.  The empirical results show a significant hysteretic effect in wine grape investment, which might be reduced by activities that smooth earnings over time.

Weather Insurance of Wine - How Quantity and Quality Regulations Affect Risks
Provedor de dados: 31
Autores: Phelippe-Guinvarc'h,   Martial.
To develop weather insurance, GROUPAMA builds a general model of agronomic crop yield density function. This approach is applied for cereal, industrial products, wine and fruits. From the density function, weather risk premium is computed. The wine-producing practices disturb our approach of risks. First, wine yields are limited by public regulations. Second, some cooperatives applied quality regulations. Then, observed crop yields are not agronomic crop yields needed by the model. The paper proposes a simulation process to estimate the agronomic parameters of areas crop yields from observed crop yields data. This process is tested on Champagne wine historical data. We measure too the impact of the quantity rules on our estimation of premium. Next, the...

Közvetlen értékesítés az egri borászatokban
Provedor de dados: 31
Autores: Gyore,   Daniel.
A tanulmány a magyar szőlő-bor ágazatban vizsgálja a közvetlen értékesítés elterjedtségét, valamint a borászok erre való hajlandóságát. A kérdőíves vizsgálat 2010-ben az Egri borvidéken zajlott, melynek eredményei azt mutatták, hogy jelentős eltérés figyelhető meg az egyes borászatok között abban, hogy milyen mértékben és milyen hatékonyan alkalmazzák a közvetlen értékesítés különböző formáit.1 A borok közvetlen értékesítésének legfontosabb eredménye az, hogy megszűnik a termelő feldolgozóval, illetve kiskereskedelemmel szemben fennálló kiszolgáltatottsága. A fogyasztónak közvetlenül értékesített borok nyereségesebbek, mint a közvetítőkön keresztül történő értékesítésnél. A vásárlókkal, borfogyasztókkal közvetlen kapcsolattal növelhető az értékesítés,...

The Financial Value of Champagne Houses in a Cobweb Economy
Provedor de dados: 31
Autores: Declerck,   Francis; Cloutier,   L. Martin.
The objective of the paper is to simulate the corporate value of Champagne makers by taking into account the Champagne market evolution. These measurements are conducted by linking financial debt, performance and valuation to a vertical coordination model of production-consumption within a cobweb economy. The overall model uses the dynamic structure that underlies the strategic interactions amongst grape producers and wine makers. These segments coordinate grape production and trade by forming expectations about final consumption, price and stock risks. The paper examines the dynamics of the financial cash flows and net worth of Champagne houses for the 1977 – 2003 period using system dynamics (SD) modeling principles. The results presented in this paper...

MODELING PERCEPTIONS OF LOCALLY PRODUCED WINE AMONG RESTAURATEURS IN NEW YORK CITY
Provedor de dados: 31
Autores: Preszler,   Trent L.; Schmit,   Todd M.
Poor perceived product quality, an inadequate sales force, and intense competition from wines produced elsewhere are common reasons cited for why New York wines have not achieved broad acceptance in the New York City (NYC) market. NYC restaurant owners, sommeliers, and chefs were surveyed regarding their perceptions and purchasing decisions of wines grown and bottled in New York State. Factor analysis was applied to examine the structure of interrelationships among key indicators of product perception, and an ordinal logistic regression model was used to identify the characteristics of restaurants that show a strong propensity to adopt local wines. The results indicate that a NYC restaurant’s type of cuisine does not affect its propensity to adopt local...

The Value of Good Neighbors: A Spatial Analysis of the California and Washington Wine Industries
Provedor de dados: 31
Autores: Yang,   Nan; McCluskey,   Jill J.; Brady,   Michael P.
The fact that wineries tend to cluster in certain sub-regions can be partially explained by the terroir of those areas.  However, a gap in our understanding of the spatial relationships among wineries remains.  In this article, winery-level data with geographic information system (GIS) coordinates are utilized to examine the spatial relationships among neighboring wineries.  Spatial effects for the California and Washington wine industries are assessed by performing clustering tests based on wine prices and tasting scores.  A spatial lag model is then estimated to test the hypothesis that there are positive effects from neighbors when analyzing the hedonic price equations.  The regression results indicate that there exists strong and positive neighbor...

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.

IMPORT DEMAND SYSTEM ANALYSIS OF THE SOUTH KOREAN WINE MARKET WITH THE SOURCE DIFFERENTATED AIDS MODEL
Provedor de dados: 31
Autores: Lee,   Young-Jae; Kennedy,   P. Lynn; Hilbun,   Brian M.
Under the assumption of block substitutability and partial aggregation, a source differentiated AIDS model was used to estimate South Korean wine import demand. Empirical results indicate that South Korean wine consumers have a strong preference for high quality French wines. French wines are shown to be substitutes for wines from other countries in the South Korean wine market. Since the implementation of a free trade agreement between South Korea and Chile, Chilean wines have steadily increased their market share exhibiting strong price competitiveness in the South Korean wine market.

BUBBLES IN PRICES OF EXHAUSTIBLE RESOURCES
Provedor de dados: 31
Autores: Jovanovic,   Boyan.
Aside from the equilibrium that Hotelling (1931) displayed, his model of non-renewable resources also contains a continuum of bubble equilibria. In all the equilibria the price of the resource rises at the rate of interest. In a bubble equilibrium, however, the consumption of the resource peters out, and a positive fraction of the original stock continues to be traded forever. And that may well be happening in the market for high-end Bordeaux wines.

Autores: Ciaschini,   Maurizio; Socci,   Claudio.
Wine is usually studied as a separate activity. Our attempt is to introduce it within the  industries  composing  output  that  react  to  disposable  income  changes.  We  first  harmonize the available data in a Social Accounting framework. From this data base  we get the parameters of a multi-industry multi-sectoral model. We apply on the model  a type of dispersion analysis based on singular value decompositions. The results show  the position held by wine with respect to the other activities in relation to changes in the  composition of disposable incomes. They confirm that wine, in a mediterranean country  as Italy, is linked to lower disposable incomes.

The Value of Terroir: Hedonic Estimation of Vineyard Sale Prices
Provedor de dados: 31
Autores: Cross,   Robin M.; Plantinga,   Andrew J.; Stavins,   Robert N.
We examine the value of terroir, which refers to the special characteristics of a place that impart unique qualities to the wine produced. We do this by conducting a hedonic analysis of vineyard sales in the Willamette Valley of Oregon to ascertain whether site attributes, such as slope, aspect, elevation, and soil types, or designated appellations are more important determinants of price. We find that prices are strongly determined by sub-AVA appellation designations, but not by specific site attributes. These results indicate that the concept of terroir matters economically, although the reality of terroir – as proxied for by locational  attributes – is not significant.

Autores: QUINA,FRANK H.; BASTOS,ERICK L.
ABSTRACT An overview is provided of the status of research at the frontiers of investigation of the chemistry and photochemistry of two classes of natural plant pigments, the anthocyanins and the betalains, as well as of the pyranoanthocyanin pigments formed from anthocyanins during the maturation of red wine. Together, anthocyanins and betalains are responsible for almost all of the red, purple and blue colors of fruits and flowers and anthocyanins and pyranoanthocyanins are major contributors to the color of red wines. All three types of pigments are cationic below about pH 3, highly colored, non-toxic, reasonably soluble in water or alcohol and fairly stable to light. They exhibit good antioxidant or antiradical activity and, as part of our diet, confer...

Alcohol and atherosclerosis
Provedor de dados: 42
Autores: DA LUZ,PROTASIO L.; COIMBRA,SILMARA R.
Atherosclerosis is manifested as coronary artery disease (CAD), ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is...

Studies have suggested that wine drinkers are at lower risk of death than beer or spirit drinkers. The aim of this study is to examine whether the risk of becoming a heavy drinker or developing alcoholic cirrhosis differs among individuals who prefer different types of alcoholic beverages. In a longitudinal setting we found that both the risk of becoming a heavy or excessive drinker (above 14 and 21 drinks per week for women and above 21 and 35 drinks per week for men) and the risk of developing alcoholic cirrhosis depended on the individuals preference of wine, beer or spirits. We conclude that moderate wine drinkers appear to be at lower risk of becoming heavy and excessive drinkers and that this may add to the explanation of the reported...

Alcohol, Wine and Platelet Function
Provedor de dados: 48
Autores: RUF,JEAN-CLAUDE.
Epidemiological studies have demonstrated an inverse correlation between moderate wine and alcohol consumption and morbidity and mortality from coronary heart disease. The protective effect has been associated with an increase in the plasma level of HDL cholesterol, as it is well recognized that plasma HDL is inversely correlated with CHD. In addition, it has become evident that blood platelets contribute to the rate of development of atherosclerosis and CHD through several mechanisms. In recent studies it has been shown that the level of HDL cholesterol can explain only 50 % of the protective effect of alcoholic beverages; the other 50 % may be partly related to a decrease in platelet activity. This anti-platelet activity of wine is explained by ethanol...

The type of diet consumed by individuals has been associated with the development of some chronic diseases, including cardiovascular disease (CVD), cancer, diabetes, and others. Populations that consume diets rich in fruits and vegetables and drink wine in moderation, as the Mediterranean, have a higher life expectancy and less chronic diseases than other occidental populations. We carried out an intervention study in humans to evaluate the effect of a Mediterranean diet (MD), an Occidental diet (OD) and their supplementation with red wine, on biochemical, physiological and clinical parameters related to atherosclerosis and other chronic diseases. For 3 months, two groups of 21 male volunteers each, received either a MD or an OD; during the second month,...

Risk of Dementia and Alcohol and Wine Consumption: a Review of Recent Results
Provedor de dados: 48
Autores: LETENNEUR,LUC.
The term dementia refers to a clinical syndrome of acquired intellectual disturbances produced by brain dysfunction. Dementia may result from a wide variety of disorders, including degenerative (e.g. Alzheimer's disease, AD), vascular (e.g. multi-infarct dementia), and traumatic (e.g. head injury). Long-term abuse of alcohol is related to the development of the Wernicke-Korsakoff's syndrome or alcohol dementia. However, light to moderate alcohol intake might also reduce the risk of dementia and AD. In Bordeaux (France), a population-based prospective study found that subjects drinking 3 to 4 standard glasses of wine per day (&gt; 250 and up to 500 ml), categorized as moderate drinkers, the crude odds ratio (OR) was 0.18 for incident dementia (p &lt; 0.01)...

The aim of this study was to compare the effects of Mediterranean-type diet (MD), high-fat diet (HFD), and red wine supplementation on plasma concentration of emergent haemostatic cardiovascular risk factors (HCVRF) and on variables of primary haemostasis (bleeding time, plasma von Willebrand factor and platelet aggregation/secretion). In a controlled prospective intervention study, two groups (21 healthy males each) received either MD or HFD during 90 days. Between days 30-60, both diets were supplemented with 240 ml/day of red wine. After adjusting by baseline values, MD was associated with: lower plasma fibrinogen (p =0.03), factor VIIc (p=0.034) and factor VIIIc (p=0.0057); higher levels of protein S (p=0.013); longer bleeding time (p=0.017); and...

A large number of prospective studies have observed an inverse relationship between a moderate intake of alcohol and coronary heart disease morbidity and mortality. Concerning death from all-causes, results are not unanimous. Alcohol intake was associated with a protection of all-cause mortality in England and USA physicians and the large study of the American Cancer Society. None of these studies separated the effects of different alcoholic beverages. In our prospective studies in France on 35 000 middle-aged men, we observed that only wine at moderate intake, was associated with a protective effect on all-cause mortality. The reason was that in addition to the known effect on cardiovascular diseases, a very moderate intake of wine, protected also from...

An experiment was carried out from 2005 to 2008, to calibrated NIR-based instrumentation and explore within field grape quality variability and map potential grape quality descriptors along vineyards, as a subsidy for differential harvesting,. The quality indicators (anthocyanin content, pH, titratable acidity and soluble solids) were subject to geo-spatial modeling. Subsequently, the data set was utilized to delineate "within-field" grape quality zone and to determine the timing of the harvest. Differential machine harvesting was implemented and segregation of wine grapes was done "on-the-go". The approach for field prediction of grape quality parameters and zone delineation allowed for separated fermentation for at least two wine styles.

For commercial purposes, the winemaking industry is constantly searching for new yeast strains. Historically, this has been achieved by collecting wild strains and selecting the best for industrial use through an enological evaluation. Furthermore, the increasing consumer demands have forced the industry to incorporate new strategies such as genetic engineering to obtain improved strains. In response to the lack of public acceptance of this methodology, alternative strategies based on breeding have gained acceptance in recent years. Through the use of conjugation of individual spores without the support of genetic engineering methods we generated intraspecific hybrids from wild strains with outstanding enological characteristics and interdelta...

Extraction of Soluble Polysaccharides from Grape Skins
Provedor de dados: 118
Autores: Gil Cortiella,Mariona; Peña-Neira,Álvaro.
Obtaining polysaccharides from grape cell walls is an interesting topic for the wine industry given its implications with regards to wine treatments and potential sensory attributes. In the present work, several conditions (i.e., a chelating agent, pH, titratable acidity, extraction time, number of successive extractions, solid to liquid ratio and alcoholic fermentation) were tested to assess their effects on the yield of soluble polysaccharides obtained from grape skins. Among the four tested solvents (i.e., water, tartaric acid, ammonium oxalate, and ethylenediaminetetraacetic acid), aqueous ammonium oxalate was the most effective for polysaccharide extraction but also produced the highest amount of protein impurities. Increasing the number of successive...

Pesticide residue in primary products is an important issue for producers and consumers, even though little information is available on the effect of application conditions on residue persistence and the transfer to primary elaborated products. During the 2012 season, field and laboratory studies were conducted to determine the dissipation of lambda-cyhalothrin, buprofezin, pyrimethanil, tebuconazole, imidacloprid and acetamiprid in Sauvignon blanc and Pinot Noir cultivars and their residue dynamics during the winemaking process. Half-life values (DT50) for each pesticide applied alone and as a tank mix of all pesticides were similar and had averages of 6.4, 14.0, 19.7, 26.0, 14.5 and 13.4 days for lambda-cyhalothrin, buprofezin, pyrimethanil,...

Analysis of major metallic elements in Chilean wines by atomic absorption spectroscopy
Provedor de dados: 118
Autores: Laurie,V. Felipe; Villagra,Evelyn; Tapia,Jaime; Sarkis,Jorge E. S; Hortellani,Marcos A.
A set of 75 wine samples from seven of the major wine producing regions in Chile were analyzed with flame atomic absorption spectroscopy (AAS) to determine their content of major metallic elements (K, Mg, Ca, Na, Fe and Zn). The results obtained were further analyzed with principal component analysis (PCA) in an attempt to loosely discriminate these wines according to grape type and geographical origin. The metal concentrations measured were within normal ranges, according to previously published data from other wine producing countries. Multivariate statistics allowed the possibility to reasonably discriminate between red and white wines, and to show a distinctive pattern of Na concentration, with higher total contents for the wines produced in the...
