Study on the Evaluation of Dairy Products Quality Properties Based on the Electronic Tongue

摘要

Applying instruments for rapid evaluation on dairy products quality are always the research focus of dairy products properties. Five brands of UHT sterilized milk and two brands of pasteurized milk were analyzed for the evaluation of quality properties by the electronic tongue. Principal Component Analysis (PCA) was used for data processing, the experiment showed that electronic tongue could discriminate not only between UHT sterilized milk and pasteurized milk, but also different brands of UHT sterilized milk or pasteurized milk. The application of electronic tongue in pasteurized milk products showed the similar results, too. As a kind of modern intelligent sensory instrument, the electronic tongue shows great potential in the evaluation of quality for dairy products.
