Method for measuring transfer action index of 13C marked perfume monomer and normal perfume monomer in cigarette

Abstract

A determination method of transfer behavior indicators of a <13>C labeled spice monomer and a conventional spice monomer in a cigarette is characterized in that the method utilizes a simultaneous distillation and extraction device and the gas chromatography-mass spectrometry method to carry out the gas chromatography analysis of the distribution of the <13>C labeled spice monomer and the conventional spice monomer which are added in the cigarette by injection in the cigarette and the transfer behavior between the mainstream smoke gas particle phase and a filter tip after the cigarette is smoked, that is, the determination method firstly adopts the analysis method to carry out the analysis and the measurement of the amount of the <13>C labeled spice monomer and the amount of the conventional spice monomer in tobacco shreds, the filter tip and cigarette paper of a flavored cigarette and a blank cigarette before the smoking and the amount of the <13>C labeled spice monomer and the amount of the conventional spice monomer in the mainstream smoke gas particle phase and the filter tip of the flavored cigarette after the flavored cigarette is smoked, thus obtaining detection values, then adopts a calculation formula for indicators researched to carry out the calculation and further carries out the comparison and measurement of the transfer indicators of the <13>C labeled spice monomer and the conventional spice monomer which are added in the cigarette in the cigarette. The determination method has the advantages of simple and rapid operation, good repeatability and high sensitivity for the analysis and the measurement.

Description

technical field [0001] The present invention relates to the field of tobacco, especially a 13 A method for determining the transfer behavior indicators of C-labeled flavor monomers and conventional flavor monomers in cigarettes. This method can be used for chemical detection results. 13 The comparative determination of the transfer behavior of C-labeled fragrance monomers and conventional fragrance monomers in cigarettes, the measurement results show that 13 The transfer behavior of C-labeled flavor monomers and conventional flavor monomers in cigarettes is consistent, indicating that the method correctly expresses the transfer behavior of conventional flavor monomers in cigarettes. The present invention provides a new analytical test for the quantitative investigation of cigarette flavoring means. technical background [0002] Foreign countries began to study the transfer behavior of tobacco components and tobacco additives during burning and smoking in the 1960s, but the...

Problems solved by technology

[0002] Foreign countries began to study the transfer behavior of tobacco components and tobacco additives during burning and smoking in the 1960s, but there were fewer studies on the transfer behavior of flavor components and spice monomers; after the 1980s, 14 C. 13 The method of C marking has been applied in the research on the transfer behavior of tobacco components and tobacco additives. The research mainly focuses on individual components such as nicotine, menthol or alkanes, and the reports on the transfer behavior of spice monomers are relatively limited; At the end of the 1980s, the research on the transfer behavior of flavor monomers during cigarette smoking began, but the 13 There is no report on the comparative study of the transfer and loss behavior of C-labeled fragrance monomers and conventional fragrance monomers.
