E-tongue performs a global analysis (fingerprint) of complex mixtures of dissolved organic or inorganic compounds, with the advantages that can not be poisoned and does not suffer fatigue
The E-tongue has a similar or better detection threshold to the human tongue for all basic tastes, says Presearch.
The main applications for the Astree E-tongue are in the pharmaceutical and food and beverage industries.
In pharmaceutical development, the taste of oral formulations is important, but it is often difficult for humans to taste test new drugs as they are toxic - whereas the Astree E-tongue cannot be poisoned.
The overall quality of food and beverages depends on both aroma and taste.
This combination defines their global organoleptic quality.
The Astree E-tongue easily measures the non/low volatile molecules (responsible for taste) and dissolved organic compounds (responsible for flavours in liquids).
It gives fast answers, with a run time of three minutes, provides tests for toxic samples and compounds, and offers direct correlations with the human tongue and HPLC analysis.
It allows analysis of liquid samples or dissolved compounds, and does not fatigue like the human tongue (particularly for bitterness).
