Distinguish Flue-cured Tobacco from Different Countries with Electronic Nose

In order to find out an effective method to distinguish flue-cured tobacco samples from different countries,the volatile components in 35 flue-cured tobacco samples from China,Brazil and Zimbabwe were analyzed by electronic nose.The collected data were analyzed with principal component analysis and linear discrimination analysis(LDA).The results showed that all the samples were correctly distinguished by the model established with LDA.The electronic nose is an effective method of distinguishing flue-cured tobacco from different countries,it can be a reference in identification by skill.
