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.
