This work presents a multiparametric system capable of characterizing and classifying white wines according to the grape variety geographical origin. Besides, it quantifies specific parameters interest for quality control in wine. The system, known as hybrid electronic tongue, consists an array electrochemical microsensors—six ISFET based sensors, conductivity sensor, redox potential sensor two amperometric electrodes, gold microelectrode sensing oxygen demand—and miniaturized optofluidic...
The main phenological stages (budburst, flowering, veraison, and ripeness) of 53 Spanish minority varieties were studied to determine their potential help winegrowers adapt climate change conditions. In total, 43 in the same location Spain (Alcalá de Henares, Madrid region) 10 5 other regions (Galicia, Navarre, Catalonia, Extremadura, Andalusia). Other traits agronomic oenological interest, such as yield acidity, also monitored. results allow for grouping into several clusters according time...
The legislation of food industry is becoming increasingly strict with regard to the quality products. Therefore, market demanding for automatic systems analysis that allow fast and accurate monitoring evolution parameters in agrofood products or permit obtaining information optimize production processes. In this context, sensors more specifically microsensors play an important role since they reproducible measurement a large number good reliability can be implemented portable systems. This...
Despite the large number of existing varieties Vitis vinifera L., only few occupy a niche in today’s highly globalized wine market. The increasing consumer demand for diversified products, as well changing climatic conditions, make establishing process varietal diversification essential to achieve both challenges. It is this reason that study minority varieties, which have higher level adaptation each area origin, particular interest. With main objective achieving an in-depth knowledge...
Downy mildew is one of the most destructive diseases affecting grapevines (Vitis vinifera L.). Caused by oomycete Plasmopara viticola (Berk. and Curt.) Berl. de Toni, it can appear anywhere where vines are cultivated. It habitually controlled application phytosanitary agents (copper-based or systemic) at different stages vine growth cycle. This, however, costly, lead to reduced yields, has a considerable environmental impact, its overuse close harvest cause fermentation problems. All...
In this work an hybrid electronic tongue for the analysis of wine is presented. Its main novelty joint use different kind sensors- potentiometric ISFETs, thin film metal microelectrodes as amperometric and conductivity sensors optofluidic system- thus allowing unprecedented measurement information a specific sample. Moreover, completed with data processing tools like Principal Component Analysis (PCA) Partial Least Square (PLS) Soft Independent Modeling Class Analogy (SIMCA). The so-called...
This study evaluates the organoleptic potential of 205 monovarietal wines made with 51 minority varieties found in Spain. The sensory analysis 90 white, 6 rosé and 109 red produced during 2019, 2020, 2021 harvests has been carried out by means an accredited tasting panel (UNE-EN ISO 10725:2017). These have characterized a total 67 descriptors (quantitative qualitative). goal work to oenological for production quality from small area cultivation, which could be more resistant drought certain...
