13. Melatonin treatment of pre-veraison grape berries modifies phenolic components and antioxidant activity of grapes and wine
Abstract A comprehensive investigation was conducted to determine the effects of exogenous melatonin treatment of pre-veraison grapes on phenolic components and antioxidants of grape berries and wine. The results showed an increase in the concentration of cyanin-3-O-glucoside, peonidin derivatives, and two flavanols [namely (+)-catechins and (−)-epicatechi

14. Process optimization, physicochemical characterization and antioxidant potential of novel wine from an underutilized fruit Carissa spinarum L. (Apocynaceae)
Abstract Carissa spinarum L., is a tropical underutilized fruit abundantly available during summer season, which is delicious to taste with an astringency flavor and fruity aroma. Hence, the present investigation was aimed at optimizing fermentation conditions for the production of wine and to assess its physiochemical composition and antioxidant activity. R

15. Identification of the potential inhibitors of malolactic fermentation in wines
Abstract This exploratory work aims to identify the potential inhibitors of lactic bacterial growth and to propose enological practices to guarantee the occurrence of spontaneous malolactic fermentation (MLF) in wines from traditional and double-pruning management harvests in southeast Brazil. One white wine from a summer harvest and one red wine from a wint

16. Anthocyanin characteristics of wines in Vitis germplasms cultivated in southern China
Abstract The anthocyanin profiles and CIELAB color values of nine wines in Vitis germplasms from southern China were compared. The results showed that the anthocyanin composition of wines from one hybrid between V. vinifera and V. labrusca (‘Moldova’), two V. labrusca varieties (‘Conquistador’ and ‘Saint-Croix’), one V. quinquangularis variety (�

17. Chemical composition of cold pressed Brazilian grape seed oil
Abstract Grape seed oil (GSO) is an important by-product of the wine-making industry which has received attention as an alternative source of vegetable oils; its chemical compounds can be influenced by agricultural practices and industrial processing. Knowledge of the composition of Brazilian GSO is scarce; thus, this study aimed to analyze the chemical char

18. Translucency and color stability of resin composite and dental adhesives as modeling liquids – A one-year evaluation
Abstract The aim of this study is to evaluate the influence of modeling liquids on the translucency and color shade of resin composites (RCs) after one year of storage. RC specimens were prepared using either a conventional insertion technique (control; without modeling liquid) or a restorative dental modeling insertion technique (RDMIT) with dental adhesive

19. Quality evaluation of red wines produced from the Isabella and Ives cultivar (Vitis labrusca): physicochemical parameters, phenolic composition and antioxidant activity
Abstract The objective of this study was to evaluate the quality of commercial red wines (Isabella and Ives [IsB]; Isabella, Ives, Seibel and Concord [IsSC]; and Isabella and Ives [IsBb]) produced from Isabella and Ives grapes grown in southern Brazil. The parameters required by Brazilian law were evaluated, and the chemical parameters of the phenolic compou

20. Rootstock on vine performance and wine quality of ‘Syrah’ under double pruning management
ABSTRACT In the Brazilian Southeast, the production of high quality wines is attained by a new management approach called double pruning. This management changes the harvesting of wine grape (Vitis vinifera L.) from wet summer to dry winter through a two pruning procedures carried out during the year. The first pruning is done during the winter to induce a v

21. Aromatic profiles of young wines from berries at different heights on grapevines
Abstract The differences among young wines from berries at 3 heights (fruit-zone 1 (FZ1): 140-200 cm above the ground; FZ2: 80-140 cm; FZ3: 20-80 cm) on Vitis vinifera L.cv Merlot and Chardonnay were assessed to evaluate the influence of berry-heights on the final wine quality.

22. Chemical and volatile composition of jujube wines fermented by Saccharomyces cerevisiae with and without pulp contact and protease treatment
Abstract This study evaluated the chemical and volatile composition of jujube wines fermented with Saccharomyces cerevisiae A1.25 with and without pulp contact and protease treatment during fermentation. Yeast cell population, total reducing sugar and methanol contents had significant differences between nonextracted and extracted wine. The nonextracted wine

24. Vinegar rice (Oryza sativa L.) produced by a submerged fermentation process from alcoholic fermented rice
Considering the limited availability of technology for the production of rice vinegar and also due to the potential consumer product market, this study aimed to use alcoholic fermented rice (rice wine (Oryza sativa L.)) for vinegar production. An alcoholic solution with 6.28% (w/v) ethanol was oxidized by a submerged fermentation process to produce vinegar.
