ASTREE Electronic Tongue

Description

ASTREE is an electronic tongue dedicated to taste analysis. This technology is based on potentiometric measurement using sensing electrodes, in order to assess the overall taste profile and compare samples taste.

The system is composed of :

An autosampler for the automated analysis of a samples set in reproducible conditions (time & stirring)
A detection system composed on an array of 7 liquid sensors
A computer with AlphaSoft software for system monitoring, data acquisition and data processing

The remarkable benefits of ASTREE electronic tongue

The use of an instrument like the electronic tongue for the sensory analysis of taste allows our customers to:

Make sensory evaluation more reliable within their company thanks to an automated, objective and reproducible measurement
Control the sensory characteristics of their products thanks to a detailed knowledge on taste attributes
Assure assessors’ safety by avoiding exposing them to potentially dangerous or unpleasant substances.

ASTREE: unsurpassed technical performance

Based on a technology of ChemFET liquid sensors and a conductivity measurement, the electronic tongue evaluates the taste of products. This analytical instrument features unique technical characteristics to achieve unsurpassed performance in taste analysis globally and also for some taste attributes (salty, acid, umami):

Evaluation of taste fingerprint : the electronic tongue detects all organic and inorganic compounds responsible for taste in liquids. With hits specific data processing software based on multivariate statistics, the instrument can assess the overall taste profile, just as the human tongue does.
Quantitative analysis capabilities: with the electronic tongue sensors it is possible to simultaneously rank similar samples according to the intensity of salty, acid and umami attributes.
Objectivity of the measurement for taste analysis: the use of an instrument like the electronic tongue to assess the taste in controlled and automated conditions assures repeatable, reproducible and totally objective results
Rapidity and high throughput of analysis : ASTREE electronic tongue autosampler allows to automate an analysis sequence of a set of samples, with a sample analyzed every 3 minutes.
