Mineral Water Taste Attributes Evaluated By Sensory Panel And Electronic Tongue

摘要

The objective of the current research was to determine relationships between sensory evaluation and measurement results obtained by electronic tongue for mineral waters. Furthermore, the purpose was to predict the sensory characteristics of the mineral waters measured by the electronic tongue and to determine taste differences that cannot be detected by the sensory evaluation. Two mineral waters were definitely different from the others according to the sensory attributes based on profile analysis. With the electronic tongue measurements the PCA and CDA analysis were found to be able to discriminate mineral waters having chemical composition similar to each other. Very good correlation was found between the sensory attributes and the electronic tongue measurements. However, the results of the measurements performed with the electronic tongue showed a more accurate discrimination of the different mineral waters than the sensory evaluation.
