Antioxidant capacity, color and total polyphenols in Nazareno and Giallo Muscat white wines produced in the São Francisco Valley, Brazil. Repositório Alice
SOUZA, J. F. de; NASCIMENTO, A. M. de S.; COSTA, A. O.; SANTOS, S. de. F.; DUTRA, M. da C. P.; PEREIRA, G. E..
One of the most produced and consumed wine from the São Francisco Valley (SFV) is the Muscat sparkling wines. The main varieties used are Italia and Canelli Muscats. Nazareno and Giallo muscat varieties are used in many regions to produce sparkling wines, presenting typical characteristics. In order to evaluate the adaptation potential of these two varieties to the VSF in the Northeast of Brazil, this work aimed to elaborate fine white dry wines by using both cultivars, and the effect of light and temperature on wine stability. Vines were planted in a partner winery in 2014 in Casa Nova city, Bahia state, Brazil. After harvested in March 2016, grapes were sent to Enology Laboratory of Embrapa in Petrolina, and wines were elaborated by traditional method of...

Enological potential of 'Pinot Noir' grape and wine from a tropical climate, in the Chapada Diamantina - BA, Brazil. Repositório Alice
COSTA, A. O.; NASCIMENTO, A. M. de S.; SOUZA, J. F. de; SANTOS, S. de F.; DUTRA, M. da C. P.; LINHARES, M. do S.; PEREIRA, G. E..
Tropical viticulture, although relatively new, has achieved significant technological developments in Brazil, making possible cultivation of vines in areas beyond standard traditional winegrowing areas worldwide. Techniques such as irrigation, the use of growth hormones in vines and production control at different times during the year, are being applied in other regions of Northeast Brazil for the production of wines. Some varieties express the best of their viticultural and enological potential in a given ecosystem, and Pinot Noir variety is very difficult to produce because presents a high susceptibility to fungal diseases (Reynier, 2007).

Evaluation of physicochemical characteristics of ?Chenin Blanc? wines in two vintages produced in the São Francisco Valley, Brazil. Repositório Alice
DUTRA, M. da C. P.; SOUZA, J. F.; COSTA, A. O.; SANTOS, S. de F.; NASCIMENTO, A. M. de S.; LINHARES, M. do S.; PEREIRA, G. E..
The predominant grapes in the São Francisco Valley (SFV) are from European origin (Vitis Vinífera L.). According to Pereira (2011) the tropical viticulture developed in this region differs from the traditional areas due to the capacity of a vine to produce more than one crop per year. Chenin Blanc is one of the main cultivar used to elaborate white wines, presenting a good adaptation to the soils and climatic conditions of the SFV area, and typical characteristics in the region. Climate changes according to the years and can influence wine characteristics (PEYNAUD, 1997). In this way, to evaluate effects of different vintages on physical-chemical characteristics of Chenin Blanc white tropical wines from SFV, this study was carried out. Wines used in this...

Evolution of Phenolic Compound Profiles and Antioxidant Activity of Syrah Red and Sparkling Moscatel Wines Stored in Bottles of Different Colors. Repositório Alice
SOUZA, J. F. de; NASCIMENTO, A. M. de S.; LINHARES, M. do S. S.; DUTRA, M. da C. P.; LIMA, M. dos S.; PEREIRA, G. E..
The objective of this study was to evaluate the effects of storage time and bottle color on the phenolic compound profiles of Syrah red and sparkling Moscatel wines stored for 12 months in green, amber, and clear bottles. The profile of the phenolic compounds and their antioxidant activity in vitro were determined. Commercial wines were bottled in an automatic filling machine and closed with natural cork. After the bottling process, the wines were stored vertically on shelves which received natural light indirectly (±8 h/day), at temperatures which varied from 24 to 30 ◦C and relative humidity 40?65%. The wines were analyzed every three months over one year. Several phenolic compound families were quantified through reversed-phase high...

Integrated analyses of phenolic compounds and minerals of Brazilian organic and conventional grape juices and wines: Validation of a method for determination of Cu, Fe and Mn. Repositório Alice
DUTRA, M. da C. P.; RODRIGUES, L. L.; OLIVEIRA, D. de; PEREIRA, G. E.; LIMA, M. dos S..
The phenolic profile and antioxidant activity (AOX) of ?organic vs. conventional? Brazilian wines and grape juices were analyzed. A simple method for the determination of minerals Cu, Fe and Mn by F-AAS was validated and used to characterize the samples studied. In the validation of the Cu, Fe and Mn determination method, the protocol for samples preparation by hot digestion with HNO3 + H2O2 proved to be more suitable for the grape juice and wine matrices. The validation parameters were considered satisfactory. Conventional products presented higher anthocyanins content, and no significant differences were observed on other phenolic compounds, AOX and Cu, Fe and Mn minerals. All the evaluated samples presented similar results between the same cultivars and...

Rapid determination of the aromatic compounds methyl-anthranilate, 2′-aminoacetophenone and furaneol by GC-MS: Method validation and characterization of grape derivatives. Repositório Alice
DUTRA, M. da C. P.; SOUZA, J. F. de; VIANA, A. C.; OLIVEIRA, D. de; PEREIRA, G. E.; LIMA, M. dos S..
A methodology for the rapid determination of the aromatic compounds methyl anthranilate (MA), 2&#8242;-aminoacetophenone (2-AAP) and furaneol by GC-MS was validated and used to characterize grape juice and wine elaborated with the new Brazilian grape varieties cultivated in northeastern Brazil, and Brazilian grape nectars. The method presented linearity (R2&#707;0.9952), good accuracy (CV< 12.9%), recovery (76.6% to 106.3%), limit of detection (23&#956;gL&#8722;1 to 94&#956;gL&#8722;1) and limit of quantification (96&#956;gL&#8722;1 to 277&#956;gL&#8722;1) acceptable in only 20 min of running. The methodology was considered satisfactory for the purpose, being a simple and rapid method for the determination of...
