1. What is the electronic tongue?

The electronic tongues simulate the human taste receptor mechanism, detect the sample information by sensor array, and analyze the overall quality of the sample with pattern recognition. Different from the chemical method, the output of the sensor detection is not the result of sample-composition analysis, but a signal pattern related to some characteristics of the sample, which can obtain the overall evaluation of the taste characteristics of the sample through the pattern recognition and analysis.

 

2. Shanghai Bosin C-tongue electronic tongue

A stable sensor array with 7 metal electrodes is mainly used in the C-tongue electronic tongue. The original idea of combined pulse relaxation spectrum is realized through voltammetry electrochemical pulse technology excitation. Through interactive induction analysis technology, the overall information of the measured object is obtained.

 

3. C-tongue application range

At present, electronic tongue has long been used in doing experiments and applied researches on the identification of true and false liquid food, such as wine, beverage, tea, etc., product quality control and shelf life, rapid detection of pesticide residues, rapid detection of pathogenic microorganisms, etc., and has shown obvious technical advantages and there have been a lot of application examples. As a new testing technology, it not only provides relevant research departments and testing departments as conventional scientific research instruments, but also provides rapid real-time means of on-site testing intelligent quality control for large-scale products.

 

C-tongue mainly used for:

Quality stability of brand industrial products and identification of true and false

Qualitative and semi-quantitative determination of certain trace components

Rapid qualitative and quantitative detection of pathogenic microorganisms

Measurement of correlation of taste sense attributes

Generalized multi-component rapid intelligent analysis
