Tobacco true and false distinguishing method based on smoke

The invention discloses a smoke-based tobacco authenticity distinguishing method. The smoke-based tobacco authenticity distinguishing method comprises the following steps: S1, collecting smoke generated after a tobacco sample is burnt; carrying out absorption treatment on the flue gas to obtain a flue gas solution; s2, mixing the flue gas solution with nanoparticles according to a set proportion to form a mixed solution; s3, collecting Raman spectrum data of the mixed solution to form a sample data set; s4, training the classification learner model by using the sample data set to obtain a trained classification learner model; and S5, collecting Raman spectrum data corresponding to the to-be-detected tobacco according to the steps S1 to S3 and the like, inputting the Raman spectrum data corresponding to the to-be-detected tobacco into the trained classification learning device model, and outputting a true and false distinguishing result of the to-be-detected tobacco.
