Qualitative and Quantitative Analysis of Selected Tonic Waters by Potentiometric Taste Sensor With All-Solid-State Electrodes
Taste sensor with five all-solid-state electrodes (ASSE) III (third version) was used for qualitative and quantitative analysis of selected tonic waters (J.Gasco, Kinley, Jurajski, Jurajski with citrus flavor, Carrefour, Schweppes Indian Tonic, and Schweppes Bitter Lemon). The results obtained by this taste sensor analyzed with principal component analysis, agglomerative hierarchical clustering methods show that this sensor can be applied for discrimination of tonic waters with respect to their composition. Based on sensor's results, two models for prediction of the content of quinine hydrochloride and total saccharides in selected tonic waters were developed using multivariate linear regression. The results obtained by this analysis in comparison to nominal data (experimentally determined and obtained from manufacturers') are consistent (range of 0.1%-1.8%). It means that taste sensor with five ASSE III may be a useful tool for the qualitative and quantitative analysis of selected tonic waters.
