To improve the objectivity, reliability, and repeatability of food sensory evaluation, and reduce human evaluation differences, electronic tongue is used to evaluate food taste.

SuperTongue is an electronic tongue (taste fingerprint analyzer) from the American brand ISENSO,Conduct taste perception index analysis on food, agricultural products, drugs, etc. Applied to various occasions that require taste evaluation, such as quality control of food, medicine and other products, new product development, complaint handling, product anti-counterfeiting, market forecasting, product evaluation, etc. At the same time, shelf life prediction and prediction of certain characteristic contents can also be carried out.

Definition of Electronic Tongue

Electronic tongue, also known as taste sensor or taste fingerprint analyzer, is a modern qualitative and quantitative analysis and detection instrument mainly composed of interactive sensitive sensor array, signal acquisition circuit, and pattern recognition based data processing method.

The basic principle of electronic tongue

The SuperTongue electronic tongue is a modern qualitative and quantitative analysis and detection instrument mainly composed of an interactive sensitive sensor array, a signal acquisition circuit, and a pattern recognition based data processing method. The stable sensor array of the electronic tongue is excited by the volt ampere electrochemical pulse technology to realize the original combination pulse relaxation spectrum idea, and then the overall information of the measured object is obtained through interactive induction analysis technology, which quickly, real-time, and online realizes the overall characteristic evaluation of the product and the rapid detection and analysis of several components qualitatively and quantitatively.
