Problems solved by technology

At present, there are many reports on the determination of phenolic compounds in mainstream smoke of cigarettes (Mao Duobin, Ma Yuping, Zhang Junsong, etc., Analysis of phenolic compounds in mainstream smoke of mixed cigarettes at home and abroad, Tobacco Science and Technology, 2002 (4): 17-20; Chinese authorized patents CN 102313782A, CN103558319A, etc.), but these determination methods usually only select harmful classified components in cigarettes such as phenol and diphenols as research objects, and many phenols that contribute greatly to the aroma of mainstream smoke Components such as 4-vinylguaiacol, 2,6-dimethoxyphenol, etc. are often not involved at the same time

Embodiment 1

[0030] The method for simultaneously measuring 19 kinds of smoked aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0031] 1) Suck the balanced and screened brand 1 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filters to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the The slices were placed in a 50 mL conical flask with a stopper and laid flat on the bottom of the bottle, 10 mL of ethanol solution and 10 μL of internal standard solution were added, shaken at room temperature for 20 min, and 2 mL of supernatant was taken to obtain a smoke sample;

[0032] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0033] The chromatographic conditions were as follows: column: DB-WAXetr (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 min ), ...

Embodiment 2

[0037] The method for simultaneously measuring 19 kinds of smoked aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0038] 1) Suck the balanced and screened brand 2 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filters to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the The slices were placed in a 50 mL conical flask with a stopper and laid flat on the bottom of the bottle, 20 mL of ethanol solution and 20 μL of internal standard solution were added, shaken at room temperature for 25 min, and 2 mL of supernatant was taken to obtain a smoke sample;

[0039] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0040] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Embodiment 3

[0043] The method for simultaneously measuring 19 kinds of smoked aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:

[0044] 1) Smoke the balanced and screened brand 3 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filters to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the The slices were placed in a 50 mL conical flask with a stopper and laid flat on the bottom of the bottle, 30 mL of ethanol solution and 30 μL of internal standard solution were added, shaken at room temperature for 30 min, and 2 mL of supernatant was taken to obtain a smoke sample;

[0045] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0046] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Abstract

The invention discloses a method for simultaneously measuring 19 smoke incense ingredients in the main stream smoke of a cigarette. The method comprises the following steps of 1) after using a Cambridge filter to gather a total particulate matter in the main stream smoke of the cigarette, transferring the Cambridge filter into an extraction container, adding an internal standard solution, then adding ethyl alcohol to extract through vibration, and taking a liquid supernatant to obtain a smoke sample; and 2) detecting the smoke sample through GC-MS (Gas Chromatography-Mass Spectrometer), and detecting the contents of 19 smoke incense ingredients through an internal standard quantitative method. According to the method, a solvent extraction-gas chromatograph mass selective detector is adopted to simultaneously measure the contents of 19 smoke incense ingredients in the main stream smoke of the cigarette, and the method has the advantages of rapidness, high sensitivity, high selectivity and high accuracy, and is particularly suitable for measuring the contents of the smoke incense ingredients in the smoke of the cigarette.

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 19 types of smoke aroma components in mainstream smoke of cigarettes. Background technique [0002] Smoky aroma is one of the important aromas of cigarettes. Quantitative analysis of smoky aroma components in cigarette smoke can investigate the key components of smoky aroma characteristics in smoke and the distribution differences of each key component in different types of cigarette smoke, which is conducive to refine the analysis of chemical components and The understanding of the relationship between sensory qualities can provide basic support for improving the sensory quality of cigarettes and simulating the style of cigarettes for new tobacco products. [0003] The main components of the smoky aroma in cigarettes are some phenolic compounds. At present, there are many reports on the determination of phenol...
