| No Brasil, a produção e o consumo de suco de uva vem crescendo nos últimos anos, sendo realizada com o uso de uma matriz diversificada de cultivares de uvas do tipo americano. Esta base inclui variedades tradicionais e suas mutações precoces, além de novas cultivares brasileiras, criadas para contribuir para a solução de demandas do segmento de sucos de uva. A viticultura brasileira voltada para a produção de sucos é praticada em diferentes sistemas de cultivo e condições ambientais, que abrangem regiões de clima temperado, onde a uva é produzida sob o sistema tradicional, até regiões de clima subtropical e tropical, onde inovações no sistema de produção permitem a realização de duas ou mais colheitas anuais. A tecnologia de extração de sucos é baseada na... |

| The production and commercialization of Brazilian grape juice is increasing annually, mainly due to its typicality, quality, and nutritional value. The present research was carried out in view of the great significance of Brazilian grape juice for the grape and wine industry. The purpose of this study, therefore, was to assess its composition as well as the discrimination between grape juice and other beverages. Twenty four samples of whole, sweetened, and reprocessed grape juices, grape nectar, and grape beverage were evaluated. Classical variables were analyzed by means of physicochemical methods; tartaric and malic acids, by HPLC; methanol, by gas chromatography; minerals, by atomic absorption spectrophotometry. These products were discriminated by the... |

| Grape juice consumption may prevent several chronic diseases owing to the presence of phenolic compounds, which have an important role in the reduction of oxidative stress. This study investigated the polyphenol content and antioxidant activities of grape juices from two cultivars: BRS-Cora and Isabella. Total polyphenol content (TPC), anthocyanins, antioxidant capacity (oxygenradical absorbance capacity, ferric reducing antioxidantpower and1,1-diphenyl-2-picrylhydrazyl), and phenolic profile (high-performance liquid chromatography with diode array and fluorescence detection ? HPLC-DAD-FLD) were determined. |

| Abstract A fast method for the simultaneous quantitative determination of 16 phenolic compounds in grape juice by UPLC-MS was developed and validated. Run time was 4.5!min and the method proved to be specific, linear (r > 0.9961), precise (RSD < 5%), accurate (recovery range was under ± 5%) and sensitive with a limit of detection ranging from 0.45 to 35.34!"g L−1 and limit of quantification ranging from 1.35 to 107.08!"g L−1. The validated method was used to characterize 49 grape juice samples which were produced with different grape varieties. Anthocyanins were the compounds present in the highest amounts on the analyzed samples and BRS-Violeta was the cultivar that presented the highest quantity of phenolic compounds in its... |

| ABSTRACT Several studies have shown that a high consumption of vegetables and fruits is consistently associated with a low risk of oxidative stress-induced diseases, which includes some degenerative diseases such as amyotrophic lateral sclerosis, Alzheimer and Parkinson. Therefore, the objective of this study is to verify the effects of conventional and organic grape juice in the modulation of the neurotrophic factor (BDNF) and astrocytic markers protein (S100B) in hippocampus and frontal cortex of Wistar rats. In this study, 24 male Wistar rats were divided into three groups. To the first one, it was given organic purple grape juice; to the second, conventional grape juice, while the last one received only saline. After 30 days, all rats were sacrificed... |

| ABSTRACT In this work, the improvement on the concentrated grape juice physico-chemical characteristics by using an enzymatic treatment followed by Membrane Separation Process (MSP) has been investigated. By using Novozym 33095(r) and Ultrazym AFP L(r) enzymes varying three operating parameters, the best result on the grape pulp characteristics was attained for the Novozym 33095(r) performed at 35oC, 15 min. and 50 mgL-1. In micro/ultra filtration processes after enzymatic pretreatment, the best performance of the MSP with high permeate flux value and suitable grape juice characteristics was attained using 0.05 mm membrane pore size, 1 bar pressure and 40 oC treatment temperature. When reverse osmosis process is operated at 40 bar and 40oC, high soluble... |

| During the summer of 2005, a total of 101 samples of wines and grape juices purchased from supermarkets and retail stores in São Paulo city were analysed for the presence of Ochratoxin A (OTA). OTA was evaluated in 29 red wines and 38 grape juices produced in Brazil and in 34 imported red wines (from Argentina, Chile, Uruguay, France, Italy, Portugal, Spain and South Africa). OTA was extracted in an immunoaffinity column and detected by HPLC with fluorescence detection, according to EN 14133/2003. The detection and quantification limits established were 0.01 and 0.03 ng/mL, respectively. The recoveries for wine samples were 94.1, 82.5, 86.1% and the relative standard deviation were 6.10, 1.03, 4.11% at levels of 0.03, 2.0, 5.0 ng/mL, respectively. For... |

| A viticultura brasileira nasceu com a chegada dos colonizadores portugueses, tornando-se uma atividade comercial a partir do início do século XX. Houve absoluto predomínio do cultivo de uvas americanas até meados do século XX, quando se iniciou o plantio de videiras europeias. Até a década de 1960, a viticultura brasileira ficou limitada às regiões Sul e Sudeste. A partir daí, a uva alastrou-se como alternativa econômica em diversas regiões tropicais do País e ganhou nova dimensão nas zonas temperadas de cultivo. Atualmente, a área vitícola brasileira situa-se ao redor de 83.700 ha, com uma produção anual oscilando entre 1.300.000 e 1.400.000 toneladas. Destacam-se, pelo volume de produção, os Estados do Rio Grande do Sul, São Paulo, Pernambuco, Paraná,... |

| Este trabalho teve como objetivo caracterizar a qualidade de uvas ?BRS Magna? produzidas sob diferentes sistemas de condução (latada, lira e espaldeira) e porta-enxertos (?IAC 572? e ?IAC 766?), no segundo ciclo de produção, nas condições do Submédio do Vale do São Francisco. O delineamento experimental utilizado foi em blocos ao acaso, em parcelas subdivididas, com quatro repetições. Foram avaliados componentes de massa do cacho, massa da baga, teor de sólidos solúveis, acidez titulável e os parâmetros de cor L, a* e b*. Não se observou combinação específica do sistema de condução e porta-enxerto que favorecesse o conjunto de componentes de qualidade avaliados. Porém, os sistemas de condução latada e espaldeira favoreceram a massa das bagas da videira,... |

| The Submedium São Francisco Valley is renowned for its particular conditions for cultivating grapes for different uses. The production of grapes for juice is relatively recent, and thus, knowledge is still limited on components of the production system. The aim of this study was to characterize the quality and antioxidant activity of ?BRS Magna? grapes in irrigated crops of the Submedium São Francisco River Valley under the influence of training systems and rootstocks, in production cycles of the first half of the year. The experiment was conducted in the Experimental Field of Bebedouro/Embrapa Semiárido, in Petrolina, Pernambuco, Brazil. The following were studied: overhead trellis, lyre, and vertical shoot positioning (VSP) systems and rootstocks ?IAC... |

| Organic acids and sugars are related to the chemical balance of wines and grape juices, besides exerting a strong influence on the taste balance and sensorial acceptance by consumers. The aim of this study was to validate a method for the simultaneous determination of sugars and organic acids in wines and grape juices by highperformance liquid chromatography (HPLC) with refractive index detection (RID) and diode array detection (DAD) and to characterize commercial products from northeast Brazil. The method provided values for linearity (R > 0.9982), precision (CV% < 1.4), recovery (76–106%) and limits of detection (0.003–0.044 g L?1 ) and quantification (0.008–0.199 g L?1 ) which are considered acceptable for application in the characterization of... |
