Problems solved by technology

The sample pretreatment process in the prior art is often complicated and takes a long time, and most of the aroma substances are volatile and semi-volatile substances, which are easy to volatilize during the long-term sampling process. After the relative peak area percentage becomes smaller, it is likely to be The peak coverage of other non-volatile substances makes the measurement difficult and the accuracy of the existing measurement is not high

Embodiment 1

[0036] The assay method of flavor components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0037] 1) Preparation of sample solution: smoke 4 cigarettes according to the conditions stipulated in "GB / T 19609-2004 Cigarette Routine Analysis Smoking Machine Determination of Total Particulate Matter and Tar (ISO 4387︰2000, MOD)" and filter with Cambridge The sheet captures the particulate matter in mainstream cigarette smoke;

[0038] Put the filter piece that has captured the total particle phase of mainstream smoke into the container, add 40ml of acetone for ultrasonic extraction for 30 minutes and then filter, the obtained filtrate is the sample solution; the power of ultrasonic extraction is 500W;

[0039] 2) The sample solution obtained in step 1) is analyzed with a comprehensive two-dimensional gas chromatography-mass spectrometer; wherein, the comprehensive two-dimensional gas chromatography adopts a double-jet liquid nitrogen cold ...

experiment example 1

[0050] The two-dimensional profiles of the mainstream smoke of the A and B two kinds of cigarette samples obtained by the method described in Example 1 are respectively as follows: figure 2 and image 3 As shown, where the abscissa is the retention time of the first dimension, and the ordinate is the retention time of the second dimension. A total of nearly a thousand compounds were detected in the two samples, including hydrocarbons (alkanes, alkenes and alkynes, cycloaliphatics, monocyclic aromatic hydrocarbons and polycyclic aromatic hydrocarbons), oxygenates (monoalcohols, phytosterols and their derivatives , aldehydes, ketones, carboxylic acids, esters and lactones) and nitrogen-containing compounds (nitriles, amines, amides, imides, N-nitrosamines, nitroalkanes, aromatic bases and nitrophenols, nitrogen heterocyclic compounds, lactams, nitrogen heteroaromatics and their derivatives and N-heterocyclic amines), etc.

Abstract

The invention discloses a method for measuring aroma components in main stream smoke of cigarettes. The method comprises the following steps: (1) placing a filter disc gathered with total particular matters of the main stream smoke of the cigarettes in an extracting solution and extracting, and filtering to obtain filtrate which is a sample solution, wherein the extracting solution is any one of acetone, dichloromethane and hexamethylene; (2) analyzing the sample solution obtained in the step (1) with a comprehensive two-dimensional gas chromatography-gas chromatograph-mass spectrometer; and (3) qualitatively and semi-quantitatively analyzing smoke components by using GC Image software. By the method, a small amount of cigarettes can be directly collected by using a smoking machine standard method to prepare the sample solution, and a complicated sample pretreatment process is not required. The method has the advantages of quick and efficient analysis, small interference, high resolution ratio, large peak capacity, accurate identification and the like, is simple to operate, and can identify various aroma components. Problems of limited peak capacity, insufficient resolution ratio, severe peak overlapping and the like in the traditional chromatography are avoided, and reliability of mass spectrometric identification is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical detection, and in particular relates to a method for measuring aroma components in mainstream smoke of cigarettes. Background technique [0002] The components of cigarette mainstream smoke, especially flavor components, are jointly produced by tobacco itself and tobacco additives (such as flavors and fragrances), which have an important impact on the taste of cigarettes, the pleasure and satisfaction of smoking cigarettes, and are also used to evaluate the sensory properties of cigarettes. key indicator of quality. Therefore, analyzing the aroma components in the mainstream smoke of cigarettes can directly understand the quality of cigarettes, and then provide information support and technical guidance for the selection of tobacco leaves and flavoring and adding materials in the process of cigarette production. [0003] The content of most aroma substances is extremely low. To separate the arom...
