A new liquid sensor analyzer has been developed to evaluate both non-volatile compounds, inorganic and dissolved organic compounds (DOC). The "α-ASTREE" Liquid Taste Analyser (Electronic Tongue) focuses on liquid analysis relevant to the food and beverage industry for both qualitative and quantitative applications. This new technology will mainly compliment taste panels. In some specific cases, it can replace taste panel analysis for simple and very repetitive applications where difference from control or conform and nonconform answers are required. This instrument can significantly contribute to taste perception applications where they play a critical role in the development and the success of many beverage and food products. In this paper, the application of the electronic tongue to product conformity is presented. This paper presents results of the Electronic Tongue "α-Astree" measurements, which have been performed on commercially soft drink samples for quality control analysis. The system correctly identified the good samples (conforms) and the samples with defaults (non-conforms) of 4 different taste attributes ; sweet, sour, bitter and salty. These attributes were higher than in the normal conforming soft drink products.
