Embodiment 1

[0028] The determination method steps are:

[0029] A. Use isopropanol as a solvent to prepare the sample. The steps are: randomly take a sample of popping bead cigarettes, put the popping beads in a headspace bottle, press the popping beads, add 10mL of isopropanol solution, shake and extract, extract The solution was passed through a 0.22 μm filter membrane. Then use gas chromatography high-resolution time-of-flight mass spectrometry (GC-TOF / MS) to perform full-scan analysis on the liquid in the popping beads to obtain a full-scan map;

[0030] B. Use the database (NIST standard spectrum library) to search to determine the unknown, and screen the key components according to the semi-quantitative results of the area normalization method;

[0031] C, for the key component screened out, with n-propyl benzoate as internal standard, determine the qualitative and quantitative parameters of the mass spectrometry of each component by gas chromatography-secondary mass spectrometry (...

Abstract

The invention discloses a method for qualitatively and quantitatively analyzing a key volatile component in cigarette bead blasting. The method comprises the following steps: (1) performing full-scanning analysis on a bead blasting isopropanol solution by a gas chromatography high-resolution time of flight mass spectrometry (GC-TOF/MS) to obtain a full-scanning atlas; (2) determining an unknown material and screening the key component by an area normalization method semiquantitative result; (3) determining the mass spectrometric qualitative and quantitative parameters of the key component by taking n-propyl benzoate as an internal standard substance and by combining gas chromatogram secondary mass spectrometry (GC-MS/MS); and (4) drawing a regression curve by a gas chromatogram secondary mass spectrometry combined multi-monitoring scanning mode, and analyzing the content of the key component accurately and quantitatively. The method is simple in operation, high in sensitivity, high inaccuracy degree, short in analysis time and suitable for performing qualitative and quantitative analysis on various volatile and semi-volatile organic compounds in bead blasting simultaneously.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for determining key volatile components in cigarette popping beads. Background technique [0002] Cigarette flavoring can endow tobacco products with a characteristic aroma and make the smoke fuller, which has an important impact on improving and stabilizing the quality of cigarettes and shaping the style of cigarettes. Therefore, cigarette flavoring technology is one of the important core technologies of the tobacco industry, and the detection and analysis method of volatile components is the most important auxiliary tool in the development of flavoring technology. [0003] Flavored with popcorn is favored by domestic consumers because of its novel flavoring method, and flavored with popcorn is more and more widely used in Chinese-style cigarettes. At present, some qualitative and quantitative studies on the volatile components of cigarettes have been repor...
