Method for detecting cut stem content in cut tobacco based on activation energy

The invention relates to the field of quality detection of cigarettes and cigarette products, in particular to a method for detecting the content of cut stems in cut tobacco based on activation energy. The content of the cut stems in the cut tobaccos is determined by calculating the corresponding relation between the cut tobaccos with different cut stem contents and the activation energy (E) through the thermal analysis test. According to the method for detecting the cut stem content in the cut tobacco based on the activation energy, a series of cut tobacco samples with different cut stem contents are prepared, and various stages of tobacco pyrolysis are effectively represented by utilizing various thermal analysis technologies; establishing a corresponding relation between samples with different cut stem contents and activation energy by virtue of a thermal analysis technology, and establishing a method for determining the cut stem blending content in the cut tobacco; the activation energy of the sample in d
