The objective of this study was to evaluate the capacity of electronic tongue (E-tongue) to analyze the quality of bottled water. The output signals of the electronic tongue for the samples were processed with pattern recognition methods. Three bands of bottled waters were successfully classified into three categories with principle component analysis (PCA) and hierarchical-cluster analysis (HCA). Discriminant factorial analysis (DFA) model was able to predict three bands of bottled waters with 100% accuracy. Soft independent modeling of class analogy (SIMCA) classification model was built up to identify the good quality bottled water and bad one (unsealed bottled water). The E-tongue may be a useful tool for rapid discriminating and monitoring quality of bottled water.
