Although there are some reports on the determination of burnt and sweet aroma components in mainstream cigarette smoke (Hong Huaqiao, Guo Ziming, Yi Ke, etc. Analysis of neutral aroma components in mainstream cigarette smoke[J]. Journal of Hunan Agricultural University: Natural Science Edition, 2008, 34(2): 164-167; Zou Peng, Shu Junsheng, Guo Dongfeng, et al. The effect of potassium carbonate on the production of neutral aroma components in flue-cured tobacco mainstream smoke[J]. Chinese Journal of Tobacco, 2014(3): 16-22.), but these determination methods usually select common furan components in cigarettes such as furfural, furfuryl alcohol and other substances as research objects, and many cyclopentenones, furanones, and pyrones Other components such as maltol, ethyl cyclopentenolone, etc. are not involved
There are few caramel-sweet aroma components detected simultaneously in the relevant literature. Therefore, it is necessary to develop a rapid and sensitive new method for the simultaneous determination of various caramel-sweet aroma components in cigarette smoke.

Embodiment 1

[0021] The method for simultaneously measuring 14 kinds of burnt-sweet aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0022] 1) Suck the balanced and screened brand 1 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the Cambridge filter Place the tablet in a 50 mL Erlenmeyer flask with a stopper and spread it flat on the bottom of the bottle, add 10 μL of internal standard solution, add 10 mL of isopropanol solution, shake at room temperature for 20 min, take 2 mL of supernatant, and obtain a smoke sample ;

[0023] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0024] The chromatographic conditions are: column: DB-5MS (60 m×0.25 mm×0.25 μm); carrier gas: He; column flow rate: 1 mL / min; inlet temperature: 250°C; temperature program: 50°C (1 mi...

Embodiment 2

[0028] The method for simultaneously measuring 14 kinds of burnt-sweet aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0029] 1) Suck the balanced and screened brand 2 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the Cambridge filter Place the tablet in a 50 mL Erlenmeyer flask with a stopper and lay it flat on the bottom of the bottle, add 20 μL of internal standard solution, add 20 mL of isopropanol solution, shake at room temperature for 25 min, take 2 mL of supernatant, and obtain a smoke sample ;

[0030] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0031] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Abstract

The invention discloses a method for determining 14 sweet aroma ingredients in mainstream smoke of cigarettes simultaneously. The method comprises steps as follows: 1) a Cambridge filter is used for capturing particle phase matter in the mainstream smoke of the cigarettes and then transferred into an extraction container, an internal standard solution and an isopropyl alcohol solution are added, the mixture is subjected to oscillation extraction, a liquid supernatant is taken, and a smoke sample is obtained; 2) the smoke sample is detected with a GC-MS (gas chromatography-mass spectrometry), and the content of the 14 sweet aroma ingredients is detected with an internal standard quantitative method. According to the method for determining 14 sweet aroma ingredients in the mainstream smoke of the cigarettes simultaneously, the content of the 14 sweet aroma ingredients in the mainstream smoke of the cigarettes can be determined simultaneously with a solvent extraction-GC-MS combined method; the method has the advantages of rapid detection, high sensitivity, good selectivity and high accuracy and is particularly applicable to determination of the content of sweet aroma ingredients in the smoke of the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of aroma component detection, and in particular relates to a method for simultaneously measuring 14 burnt-sweet aroma components in mainstream smoke of cigarettes. Background technique [0002] Burnt sweet aroma is one of the important benign aromas in cigarette smoke. It has a crucial impact on the sensory quality of cigarettes, and has received extensive attention from domestic and foreign tobacco companies. The quantitative analysis of the burnt-sweet aroma components in cigarette smoke can investigate the key components of the burnt-sweet aroma characteristics in the smoke and the key components in the smoke. The distribution differences in different types of cigarette smoke are conducive to refining the understanding of the relationship between the chemical components of smoke and sensory quality, and can provide basic support for improving the sensory quality of cigarettes and simulating the style of c...
