The invention discloses an electronic nose based paraffin taste and odor grade assessment method. The electronic nose based paraffin taste and odor grade assessment method comprises the following steps: S1, acquiring related data of taste and odor of paraffin through an electronic nose; S2, reducing the dimension of the related data of the taste and odor of the paraffin by means of principle component analysis and partial least squares; S3, using a support vector machine to construct a model for characteristic data sets of the #PCA, #PLS and #universal set, and classifying and accessing the grade of paraffin samples at different taste and odor grades. The method achieved data acquisition and data analysis, the data of the well prepared to-be-inspected paraffin samples are directly acquired, and the grade of the paraffin is rapidly efficiently identified according to the ingredient characteristic of the paraffin at different grades. 本发明公开了种基于电子鼻的石蜡嗅味等级评定方法，包括如下步骤：S1、通过电子鼻进行石蜡嗅味相关数据的采集；S2、采用主成分分析、偏最小二乘对石蜡嗅味相关数据
