"Electronic tongue" in the Food Industry
Tanya Titova, Veselin Nachev
Abstract
“Electronic tongue” (e-tongue) is instrumental system are designed to crudely mimic human taste sensory organs and are composed of an array of sensors. Complex data sets from „e- tongue“ signals combined with multivariate statistics represent rapid and efficient tools for classification, recognition and identification of samples, also for the prediction of concentrations of different compounds. A wide variety of sensors can be employed into the design of these instrumental systems, especially that of „e-tongues“, offering numerous practical applications. In this study are review, characteristics of sensors and possibilities „e-tongue“ applications in the food industry.Practical applications: The “e-tongue” can be used in various applications, including on quality control in the food industry and pharmacy.
