Abstract Grapevines can be grown in different soil classes and climatic conditions. However, the effect of these variables on grapevine and grape composition is complex. The aim of this study was to evaluate the effect of soil classes and climatic conditions on productive and physico-chemical characteristics and phenolic compounds of Cabernet Sauvignon grapes. The experiment was carried out in São Joaquim (SC), located on the Southern Plateau of Santa Catarina. Cabernet Sauvignon variety was analyzed in three soils (Dystrudepts, Humudepts and Rhodudalfs) and two harvests (2015 and 2016). The climatic variables analyzed were rainfall, insolation and average, maximum and minimum temperatures. Soil physical-chemical attributes, productive and physico-chemical characteristics and phenolic compounds of grapes were analyzed. Both soil class and harvests had significant effect on productive and physico-chemical characteristics and phenolic compounds of grapes. Soil was more important for productive characteristics and phenolic compounds, while meteorological conditions were more important for the physico-chemical characteristics of grapes. Productive characteristics and grape composition were more adequate to wine production in the 2016 harvest and in Rhodudalfs and Dystrudepts soil classes.

Os tratamentos aplicados foram: irrigação plena - irrigação realizada durante todo o ciclo de produção; irrigação com déficit controlado - onde a irrigação foi interrompida aos 49 dias após a poda, sendo realizadas eventuais irrigações após a interrupção, de acordo com o monitoramento da água no solo; e a irrigação com déficit, onde a aplicação de água foi interrompida desde os 49 dapp até a colheita. O potencial hídrico foliar foi medido utilizando a bomba de Scholander. Os índices de clorofila a, b e total foram mensurados utilizando o dispositivo portátil (ClorofiLOG - CFL 1030). As coletas de dados referentes a atividade fotossintética foram determinadas a partir do analisador portátil de gás por infravermelho (Modelo Li-6400). Os ácidos orgânicos e os compostos fenólicos foram quantificados utilizando a cromatografia líquida de alta eficiência. O déficit de irrigação reduziu o potencial hídrico, a fotossíntese, a produtividade, o ácido tartárico e aumentou a concentração de compostos fenólicos. Vinhos obtidos de uvas de plantas dos tratamentos com déficit podem ser destinados a elaboração de vinhos de guarda. Palavras-chave: Vitis vinifera L., Syrah, semiárido, clorofila, ácidos orgânicos.  NASCIMENTO, R.

O.GAS EXCHANGE AND PHYSICAL-CHEMICAL COMPOSITION OF WINES DUE TO IRRIGATION STRATEGIES  2 ABSTRACT The study aimed to evaluate changes in physiological variables and physicochemical composition of wines from vines subjected to different irrigation strategies. The treatments were: full irrigation – applying water throughout the whole crop season, regulated deficit irrigation – interrupting the irrigation at 49 days after pruning and applying water according to soil water monitoring, and deficit irrigation – interrupting the watering 49 days after pruning to harvest. The leaf water potential was measured with a Scholander pressure chamber. The chlorophyll a, b and total indexes were measured using a portable device (ClorofiLOG - CFL 1030). The photosynthetic activity data were determined with the portable infrared gas analyzer (LI-6400 Model). The organic acids and phenolic compounds were quantified using high-performance liquid chromatography. Deficit irrigation reduced the water potential, photosynthesis, productivity, tartaric acid and increased the concentration of phenolic compounds. Wines from vines grapes under deficit irrigation may be indicated for aged red wine production. Keywords: Vitis vinífera L., Syrah, chlorophyll, semi-aride, acids organic

The occurrence of 14 phenolic compounds (PCs) was assessed in the raw, treated wastewater, dewatered sludge and gas samples from a coking wastewater treatment plant (WWTP) in China. It was found that 3-cresol was the dominant compound in the raw coking wastewater with a concentration of 183 mg L−1, and that chlorophenols and nitrophenols were in the level of μg L−1. Phenol was the dominant compound in the gas samples, while 2,4,6-trichlorophenol predominated in the dewatered sludge sample. The anaerobic and aerobic tanks played key roles in the elimination of chlorophenols and phenols, respectively. Analysis of daily mass flows of PCs in WWTP showed that 89–98% of phenols and 83–89% of nitrophenols were biodegraded, and that 44–69% of chlorophenols were adsorbed to sludge, indicating that the fate of PCs was highly influenced by their biodegradability and physical–chemical property.

Many fruit species are still not well-studied, despite being rich in bioactive substances that have functional properties. The objective of this article was to evaluate the antioxidant potential and characterize the physical-chemical characteristics of unconventional brazilian fruits (cabeludinha - Myrciaria glazioviana, sapoti - Manilkara zapota, pitomba - Talisia esculenta, yellow gumixama - Eugenia brasiliensis var. Leucocarpus and seriguela - Spondias purpurea). Total soluble solids, pH, titratable acidity, sugars, pigments, phenolic compounds and antioxidant capacity were measured. Mature fruits were used in the analyses. Pitomba had high levels of soluble solids, 24.6 °Brix, while sapoti had 0.05 g malic acid 100 g-1 pulp. Yellow grumixama and seriguela had the highest concentrations of anthocyanins and carotenoids. Cabeludinha had a high concentration of phenolic compounds, 451.60 mg gallic acid 100 g-1 pulp. With the exception of sapoti, all fruits had a high antioxidant capacity (> 95%).

Disposal of the waste from wine production has long been a problem for wineries, mainly because of the presence of phenolic compounds. In this study, we analyzed the antimicrobial activities of 10 wine phenolic compounds against Lactobacillus plantarum strains. Inhibition increased in this order: catechin = gallic acid < epicatechin = salicylic acid < methyl gallate = caffeic acid < ferulic acid = tryptophol < p-coumaric acid. The obtained results indicated that L. plantarum is able to grow in the presence of high concentrations of some wine phenolic compounds. Of the 10 compounds analyzed, only the hydroxycinnamic acids, gallic acid, and methyl gallate were metabolized by the four L. plantarum strains studied. Results also revealed that 4-vinylphenol and 4-vinylguaiacol are originated from p-coumaric and ferulic acids. These phenolic compounds are valuable intermediates in the biotechnological production of new fragrances. In addition, gallic acid and its ester, methyl gallate, are metabolized to produce the powerful antioxidant pyrogallol. Therefore, it might be possible to use L. plantarum strains to obtain high-added-value antioxidants from the degradation of phenolic compounds found in wine wastes.

The aim of the study was to determine the technological stock of phenolic compounds in European technical grape varieties grown in the climatic conditions of Uzbekistan, used to produce white and red wines. UV-Vis spectrophotometric method determined the total content of phenolic compounds in localized wine-technical grape varieties. Using high performance liquid chromatography (HPLC), the qualitative and quantitative content of groups and subgroups of phenolic compounds was studied, biologically active components obtained in the process of their extraction were identified, and studies were carried out to analyze the types of phenolic compounds by chromatographic separation in certain wine-technical grape varieties. Chromatographic separation, identification and qualitative analysis of phenolic compounds revealed 2 groups of phenol-carboxylic acids, 9 groups of dihydroxy acids, 7 groups of flavan-3-ol, 12 groups of flavonols and 15 groups of anthocyanins, as well as, 2 tannins. Also revealed the presence of flavonoids, which have such advantages as the individual identification of their polymer products. Studies have shown that local grape varieties have a high degree of phenolic retention. This result opens up tremendous opportunities for future scientific improvement of wine production technology

There are many studies about the biological activities of Vitis vinifera grape seeds, which are rich in phenolic compounds, known by their several health beneficial effects. However, until now there is no data about biological activities of the seeds of V. labrusca, specie found in South and North America. Every year, the global wine production (around 260 million hL) generates about 19.5 million ton of wastes, which are usually discarded in the environment. The aim of this research was to evaluate the antioxidant and anti-inflammatory activities of aqueous extracts of seeds from wine wastes of Vitis labrusca (cv. 'Bordo' and 'Isabella'). Both extracts showed significant antioxidant and anti-inflammatory activities, which are positively correlated with total phenolic content, suggesting that these compounds might be the major contributors to the biological activity of these extracts. These results indicate that water extraction from winery wastes is an option to obtain phenolic compounds with antioxidant and anti-inflammatory activities helping to maintain environmental balance.
