The invention discloses a method for measuring the release rate of a non-polar or low-polar flavor component in a smoke-free tobacco product, which is mainly used for determining the release rate of the non-polar or low-polar flavor component in the smoke-free tobacco product by performing preliminary treatment and apparatus analysis on the smoke-free tobacco product. The method specifically comprises the following steps: weighing two parts of equivalent smoke-free tobacco products, adding artificial saliva and a methylene dichloride standard substance solution respectively, sealing and oscillating the mixture, extracting saliva extract twice with the equivalent methylene dichloride standard substance solution, combining the extract liquors, drying the combined extract liquor for cold storage and then feeding a sample in a concentration way; performing separation and detection on an extracted component with GC and GC-MS, retrieving and determining the content of the non-polar or low-polar flavor component according to a retaining time and a mass spectrum database, and comparing the content of the extracted component in the saliva with the content of the directly extracted component of the methylene dichloride solution so as to obtain the release rate of the flavor extracted component of the smoke-free tobacco product. The method has the advantages of simple process, high analysis speed, good accuracy, unlimited sample physical state and the like.
