Electronic tongue for flow-through analysis of beverages

The paper describes the application of the electronic tongue based on a sensor array of miniaturized solid-state potentiometric electrodes in the flow-through analysis of beverages. The system was tested in the brand recognition of various beverages: beer, juice and milk. The fusion of ion-selective and partially selective microelectrodes in the sensor array and the combination of PCA/BPNN techniques led to the recognition of beverages with high correctness.
