Problems solved by technology

Commonly used gas chromatography and liquid chromatography fingerprint analysis have a long inspection cycle and selective analysis, and cannot fully characterize the characteristic components of tobacco flavors and fragrances, and the analysis of the similarity of fingerprints mostly uses the cosine method of the included angle. When calculating the similarity of chromatographic fingerprints, the cosine method is not sensitive to the influence of equal proportion changes and small peaks, and has certain shortcomings, and cannot accurately reflect the differences of flavors and fragrances.

Abstract

The invention relates to an essence and flavor Fourier transform ion cyclotron resonance mass spectroscopy fingerprint analysis method. The method comprises diluting an essence and flavor sample to be detected through a solvent to obtain a solution of the sample to be detected, carrying out Fourier transform ion cyclotron resonance mass spectroscopy fingerprint analysis on the solution of the sample to be detected through a direct sample introduction method to obtain a fingerprint of the sample to be detected, building a Fourier transform ion cyclotron resonance mass spectroscopy standard spectral library of an essence and flavor standard sample, determining a common characteristic ion peak according to the fingerprint of the sample to be detected and the standard spectral library, calculating a similarity matching score of the essence and flavor sample to be detected and the essence and flavor standard sample according to the response of the common characteristic ion peak in the fingerprint of the sample to be detected and in the standard spectral library, and determining quality stability and difference of the essence and flavor sample to be detected so that essence and flavor Fourier transform ion cyclotron resonance mass spectroscopy fingerprint analysis is finished. The method is free of chromatographic column separation, realizes direct sample introduction and analysis, has a simple pre-treatment process, and realizes fast and accurate analysis.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of analysis of flavors and fragrances, in particular to a method for analyzing the fingerprints of flavors and fragrances by Fourier transform ion cyclotron resonance mass spectrometry. [0003] 【Background technique】 [0004] Tobacco flavors and fragrances can improve the smoking quality of cigarettes and impart characteristic aroma to cigarettes. They are an important factor in the style of cigarette brands and are closely related to the quality and stability of cigarette products. At present, the quality of flavors and fragrances is mainly determined by physical and chemical indicators (ethanol, 1,2-propanediol, glycerol, acid value, relative density, refractive index, total volatile components) and sensory indicators (appearance, miscibility, aroma and aroma) Quality) two links to control. The above method has the disadvantages of long inspection period, many types of instruments and equipment, large tole...
