Influence of temperature and storage time on anthocyanin stability of grape juice treated by hot filling.

The objective of this study was to analyze the storage temperatures on anthocyanins content of grape juices bottled hot, simulating inadequate cooling and storage conditions

Phenolic compounds and antioxidant activity of commercial tropical red wines (Vitis vinifera) from the São Francisco Valley, Brazil.

The sub-middle region of the São Francisco Valley (SFV), located in northeastern Brazil, is different from other Brazilian wine producing regions and major world wine producing areas, because this region has specific climatic conditions, since the SFV is situated between the southern hemisphere parallel of 8-9º and at 350 m altitude in a semi-arid tropical climate zone, with average temperatures of 26°C, high intensity sunlight (3,000 h/year) and low annual rainfall (about 500 mm) (Teixeira et al., 2013). These different weather conditions, coupled with the absence of a winter and application of water by irrigation, make it possible to obtain 2 crops in the SFV in the same year. In order to learn about tropical wines better, such as those produced in SFV, there is a need to characterize these products in order to show the specificities of the qualities related to their region of origin

Delayed luminescence in relation to the germination and vigour of coffee seeds: initial series with C. Arabica samples.

Ultra-weak delayed luminescence measurements on coffee seeds were run for samples submitted to different post-harvest treatments or in seed lots with different vigour levels obtained by accelerated aging, and both were induced to germinate afterwards. Parameters of hyperbolic decay fitting were correlated to the correspondent germination vigour, with a linear relation found for the initial value as well as for the decay velocity. These preliminary data point to further, broader validation for this non-invasive, non-destructive test for seed?s viability analyses

Phenolic profile and antioxidant activity of commercial grape juices from the São Francisco Valley, Northeastern of Brazil.

In recent years, The Sub-middle region of the São Francisco Valley (SFV), located in the Northeast of Brazil, has invested in the production of grape juice from new Brazilian varieties developed for preparation of high quality juices, such as Isabel Precoce (Vitis labrusca L.) and hybrids (Vitis labrusca L. x Vitis vinifera L.) BRS Violeta, BRS Cora and BRS Magna (Lima et al., 2014). Grape juice in this region have been highlighted by the good bioactive content, high antioxidant activity associated with phenolic compounds and to promote anti-inflammatory activity in consumers (Toscano et al., 2015)

Anthocyanin composition of young red wine cv. Ruby Cabernet and Syrah: effect of time and storage conditions.

The aim of this study was to evaluate the evolution of anthocyanins in red wines for 12 months of storage in bottles in two different conditions. The wine samples cv. Ruby Cabernet and cv. Syrah (Vitis vinifera L.) used for this study were produced in the Sub-middle São Francisco Valley, in the Northeast Region of Brazil, during the 2013 harvest
