An electronic nose (PEN3) was used to characterize and classify three different treatment methods of the myrica rubra juice. This method firstly sampled aroma composition emanating from the myrica rubra juice by PEN3 systems and then obtained response values of PEN3. After this, data analysis was conducted by using principal component analysis(PCA) and linear diserimination analysis(LDA). The results of this study showed that electronic nose was able to identify the different treatment methods of the myrica rubra juice by PCA and LDA．The basic research data and approach was provided for the myrica rubra juice processing with the blend modified polysulfone membrane determinations using a portable electronic nose.
