Abstract: In this research,the detection of fermentation and enzyme uncoupling fermentation processing of Yunnan arabica coffee fruit and green bean was carried out by electronic tongue detection. Then the principal component analysis and cluster analysis it was used to analyzing the relationship among the natural civet coffee and other different processing methods and origins of the coffee beans. The result showed that the fermentation and enzyme uncoupling beans(MX simulation beans) and natural civet coffee beans were similar highest,which proved that the fermentation and enzyme uncoupling of coffee fruit could get the same natural civet coffee flavor of coffee beans,and provided a new idea for the production of artificial musk cat coffee beans.
