The basic principle of Smartongue
Sensor display
Non-specific sensors
Has some specificity , and interact with a sensor excitation signal acquisition system
Related to the design of the sensor display
Associated with the nature of the object under test
Multivariate statistics system
The bureau of inspection on differences between object overall qualities(PCA)
The identification on origin authenticity protection products and brand products（SIMCA、PLS-DA）
Product quality grading(DFA)
Samples sensory attributes and physical and chemical indicators of rapid response (PLS)
Evaluation of product shelf life (PCA, PLS
Owning a very wide range of applications
The division and detection of five basic taste substances——sour, weet,bitter,salty and delicate taste.
Food:Alcohol, beverage,tea,aquatic products, livestock,poultry and egg products
Edible oil , fruits and vegetables plus attack , dairy products, cooking food, pharmaceutical, health food, tobacco
Rapid detection of pesticide residues , rapid detection of pathogenic microorganisms
Five distinguished characteristics of smart tongue
Rapid:Without any pre-treatment,sample can be tested directly at present.Meanwhile ,we can get the desired result in 1~3 minutes.The machine which has a high sensitivity and vast information(several orders of magnitude more than other electronic tongue’s original information) can be cleaned automatically.The operation is simple and reliable which has provided a realistic possibility to the intelligent processing.
Stable:A special screening of inert precious metal sensor array according to the test objects with a high performance stability and repeatability is the most stable commodity electronic tongue system.The system can be used for many years without replacement.
Extensive:Corrosive samples or fats and oils samples can be detected easily.Such as liquor , edible oil and so on can be directly detected.
Elastic:Smart tongue is a kind of universal tongue broad spectrum of intelligence analysis instruments, with maximum flexibility and scalability. It can be combined with the specific needs of users and sample data model libraries to define and expand its function and change into dedicated electronic tongue models for different purposes and different environments.
Autonomous:Smart tongue entirely based on independent intellectual property rights has originality in the principles and technique,including the application software which is completely designed to the Chinese people.The friendly background and targeted operation is suitable for the Chinese people’s thinking concepts and operating practices.The whole system performances cost-effective and is easy to maintenance .
The identification to the basic state substance:
Flavor substances in food are classified as five basic tastes like sour,sweet , bitter, salty, fresh.By identifying the sensor and processing computer software ,namely through the concept of " WAN selective " to identify,evaluate the taste ,and then you can view and count the taste of the tongue
