The invention discloses an SIMCA-based taro flavored pumpkin resource identification method. The method comprises the following steps: preparing a taro flavored pumpkin sample and a non-taro flavoredpumpkin sample; respectively obtaining initial smell data of the pumpkin sample with the taro flavor and the pumpkin sample with the non-taro flavor through an electronic nose system; the initial smell data at least comprises training data of the flavor of the taro; carrying out data preprocessing, obtaining maximum response value data corresponding to each sensor in the initial smell data of thepumpkin sample with the taro flavor, and rearranging the data into a two-dimensional data form; constructing an SIMCA recognition model according to the training data of the taro flavor, obtaining recognition smell data of the to-be-detected sample through an electronic nose system, inputting the recognition smell data into the recognition model for recognition, and outputting a recognition result. The method is based on t
