Electronic Tongue (E-Tongue)

Electrochemical cell, sensor array and appropriate pattern recognition system capable of recognizing simple or complex soluble non-volatile molecules that forms a taste of a sample.

Electrochemical cell consists of working electrodes, reference electrode and counter electrode.

The sensor array consists of broadly tuned (non-specific) potentiometric metal-based electrodes.

Applications:

E-Tongue for taste characterization.

E-Tongue for monitoring of aging of tea.

Use Cases

• Regular assessment of tea quality during tea production by the Tea Industry.
• Quality testing of tea sample during Tea Auction.
• Testing of quality of tea samples during tea blending.

• Distinguishes tea samples having different astringency values with an accuracy of more than 85%.
• Complete tea testing operation in a single mouse click.
• Mimicking Tea Taster Scores by electronic means.
• Auto cleaning of electrodes by clean water.
• User-friendly software.
• Voltammetric technique is used for sample analysis.
• GUI for ease of operability.
• PC based acquisition & control for sample handling.
• Display of Tea Tasters’ like Scores.
• Flexibility for customizing the S/W as per User’s requirement.
