Thedefinition of Smartongue
Also known as gustatory sensor or tastefingerprint analyzer ,it is a qualitative and quantitative analysis of moderninstrumentation major constituted by the interaction sensitive sensor display，signal acquisition circuit and thedata processing method with good Pattern Recognition。（The definition comes fromYu.Vlasov,et al,/ Pure and Applied Chemistry 77,1965-1983）
The basic structure of Smartongue
Sensor display
Non-specific sensors
Has some specificity , and interact with asensor excitation signal acquisition system
Related to the design of the sensor display
Associated with the nature of the objectunder test
Multivariate statistics system
The bureau of inspection on differencesbetween object overall qualities(PCA)
The identification on origin authenticityprotection products and brand products（SIMCA、
PLS-DA）
Product quality grading(DFA)
Samples sensory attributes and physical andchemical indicators of rapid response (PLS)
Evaluation of product shelf life (PCA, PLS)
Owning a verywide range of applications
Food:Alcohol, beverage,tea,aquatic products, livestock,poultry andegg products
Edible oil , fruits and vegetables plus attack , dairy products,cooking food, pharmaceutical, health food, tobacco
Rapid detection of pesticide residues , rapid detection ofpathogenic microorganisms
Fivedistinguished characteristics of smart tongue
Rapid:Without any pre-treatment,samplecan be tested directly at present.Meanwhile ,we can get the desired result in1~3 minutes.The machine which has a high sensitivity and vast information(severalorders of magnitude more than other electronic tongue’s original information)can be cleaned automatically.The operation is simple and reliable which hasprovided a realistic possibility to the intelligent processing.
Stable:A special screening of inertprecious metal sensor array according to the test objects with a highperformance stability and repeatability is the most stable commodity electronictongue system.The system can be used for many years without replacement.
Extensive:Corrosive samples or fats andoils samples can be detected easily.Such as liquor , edible oil and so on canbe directly detected.
Elastic:Smart tongue is a kind ofuniversal tongue broad spectrum of intelligence analysis instruments, withmaximum flexibility and scalability. It can be combined with the specific needsof users and sample data model libraries to define and expand its function andchange into dedicated electronic tongue models for different purposes anddifferent environments.
Autonomous:Smart tongue entirely basedon independent intellectual property rights has originality in the principlesand technique,including the application software which is completely designedto the Chinese people.The friendly background and targeted operation issuitable for the Chinese people’s thinking concepts and operating practices.Thewhole system performances cost-effective and is easy to maintenance .
Theidentification to the basic state substance:
Flavor substances in food are classified as fivebasic tastes like sour,sweet , bitter, salty, fresh.By identifying the sensor andprocessing computer software ,namely through the concept of " WANselective " to identify,evaluate the taste ,and then you can view andcount the taste of the tongue.
