Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
(MDPI, 2019-01)Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ... -
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
(BMC, 2010-08)Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ... -
Physicochemical properties, degradation kinetics, and antioxidant capacity of aqueous anthocyanin-based extracts from purple carrots compared to synthetic and natural food colorants
(Elsevier, 2022-04)As a mans to evaluate the potential of carrot anthocyanins as food colorants and nutraceutical agents, we investigated the physicochemical stability and antioxidant capacity of purple carrot extracts under different pH ... -
Piranoantocianos : nuevos pigmentos en los vinos tintos. Aspectos científicos e implicancias tecnológicas.
(2006-08)El universo del color de los vinos tintos es complejo, dentro del mismo actúan diversos compuestos que provienen de la uva y otros que son formados durante los procesos de vinificación y añejamiento de los vinos. Las ... -
Pretreatments Effect in Drying Behaviour and Colour of Mature and Immature ‘Napolitana’ Sweet Cherries
(Springer, 2014-06)The effect of different treatments on drying behaviour and colour of mature and immature cherries (Napolitana var.) has been studied. Drying was carried out at 70 °C with air at 4 m/s speed and 8 % relative humidity, and ... -
Regulated Deficit Irrigation Alters Anthocyanins, Tannins and Sensory Properties of Cabernet Sauvignon Grapes and Wines
(2015-04)Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard ... -
Relationships among Gene Expression and Anthocyanin Composition of Malbec Grapevine Clones
(2014-07)Anthocyanin profiles are commonly used for grapevine cultivar identification because it is currently accepted that this trait is closely related to their genetic characteristics. Nevertheless, the extent of the variation ... -
Review: critical appraisal of methods to investigate the effect of temperature on grapevine berry composition
(Wiley, 2015-02)The grapevine is an economically important crop and a model species of long‐lived perennials widely used in bioclimatic studies. Ambient temperature modulates berry composition, hence the significant research effort in ... -
Soil water availability during spring modulates canopy growth and impacts the chemical and sensory composition of Shiraz fruit and wine
(Wiley, 2021-06)Background and Aim: Reduced rainfall during vine dormancy and supplementary irrigation during winter or at spring impact on vine growth partitioning. We assess the implications that induced changes on canopy growth due to ... -
Spray-dried Ancellotta red wine: natural colorant with potential for food applications
(Springer, 2019-10-04)Ancellotta red wine (Vitis vinifera L.) was encapsulated by spray-drying (inlet and outlet temperatures were 145 °C and 70 °C, respectively) to obtain a wine powder with a low water activity (aw) using maltodextrin DE10 ... -
Timing of nitrogen fertilization influences color and anthocyanin content of apple (Malus domestica Borkh. cv ‘Royal Gala’) fruits
(Taylor and Francis, 2011)Different timings and methods of N application modify N dynamics in the plant and could have differential effects on fruit color. To evaluate this possibility, an experiment was conducted during three seasons in a ‘Royal ... -
Transcriptional regulation of the anthocyanin biosynthesis pathway in developing grapevine berries in cultivar ‘Malbec’ by putative R2R3 MYB negative regulators
(Elsevier, 2019-11)In grapevine, proanthocyanins (PAs) and anthocyanins are obtained via the phenylpropanoid pathway. These metabolites are synthesized in specific tissues of the berry and accumulate in different developmental stages. The ...
