Wine and Combined Electronic Nose and Tongue

Wine is a complex chemical matrix and for this reason, human panels are widely used in the industry for the global evaluation of wine samples. Chemical sensor arrays (electronic nose and electronic tongue) represent the instrumental alternative to this global analysis, since their working mechanism can reproduce the classification properties of sensorial analysis and also quantify both sensorial descriptors and chemical parameters of wine. The evidence that human senses cooperate in the sensory evaluation led to study the integration of these devices and, in some cases including also optical systems, to develop an electronic panel able to better mimic the human panel evaluations. In this chapter we reviewed the different applications of these integrated sensor systems for the analysis of wine. © 2016 Elsevier Inc. All rights reserved.
