Problems solved by technology

Therefore, there are more interfering substances in the detection after flavoring, making the detection more difficult, which in turn affects the accuracy of its analysis
At present, there is no standard method established for the above-mentioned migration detection, and an analysis method with high accuracy and reliable detection quality can be realized.

Embodiment 1

[0053] Sample processing and instrument detection steps are as follows:

[0054] 1. Smoke the sampled cigarettes according to the ISO standard smoking conditions, smoke 4 cigarettes for each experiment, and the length of the cigarette butt is 33cm. A Ф44mm Cambridge filter was used to capture the particulate matter of mainstream cigarette smoke, and a Carbotrap349 thermal desorption sampling tube was connected in series behind the trap to capture the gas phase matter of mainstream cigarette smoke.

[0055] 2. Select D3-phenethyl acetate as the internal standard solution, the concentration is 0.02g / mL, and the solvent is dichloromethane. Add 3 μL of internal standard solution to each thermal desorption sampling tube, and then use ATD-GC / MS to inject and analyze.

[0056] 3. See Table 1 and Table 2 for the analysis and detection conditions of thermal desorption (ATD) instruments and gas chromatography-mass spectrometry (GC / MS) instruments.

[0057] Table 1 Thermal desorption c...

Embodiment 2

[0082] Taking the flavoring material A as an example, the analysis method of the transfer behavior of the flavoring material in the gas phase of mainstream cigarette smoke is introduced.

[0083] 1. Analysis of gas phase components of cigarette mainstream smoke before and after the addition of flavoring material A. For the composition analysis of flavoring material A, see figure 1 .

[0084] The composition analysis method of fragrance raw material A is as follows: take 10 μL of fragrance raw material A, dissolve it in ethanol / dichloromethane / dimethylformamide in an appropriate proportion, and perform detection according to the GC / MS conditions in Table 5. (A suitable solvent can be selected according to the dissolution situation. When the main component concentration in the analyte is low, the sampling amount of the fragrance raw material can be appropriately increased.), and its components are qualitatively analyzed with the NIST library and the AMDIS library, as listed in T...

Abstract

The invention provides a method used for detecting perfume component migration of main stream smoke gas phase composition of flavored cigarettes. The method comprises following steps: firstly, suction of flavored cigarette samples is carried out; Cambridge filter is used for collecting main stream smoke gas particle phase matters, series connection of a thermal desorption sampling pipe is carried out, and a thermal desorption device and a gas chromatograph-mass spectrometer are adopted for detection analysis, wherein sampling pipe desorption temperature is controlled to be 320 to 340 DEG C, desorption time is controlled to be 30 to 50min, desorption flow speed is controlled to be 50ml / min, inlet shunt rate is controlled to be 150ml / min, outlet shunt rate is controlled to be 100ml / min, temperature programming is performed as following: a temperature of 40 DEG C is maintained for 33min, the temperature is increased to 80 DEG C at a rate of 2 DEG C / min, the temperature of 80 DEG C is maintained for 10min, the temperature is increased to 250 DEG C at a rate of 10 DEG C / min, and the temperature of 250 DEG C is maintained for 30min. The method can be used for migration detection analysis of perfume components of flavored cigarettes, and controlling flavored cigarette quality and adjusting smoke flavor preferably.

Description

technical field [0001] The invention belongs to the technical field of detection of flavored cigarettes, and more particularly relates to a method for detecting the migration of spice components in the gaseous phase of mainstream smoke of flavored cigarettes. Background technique [0002] The aroma and taste of cigarettes are mainly derived from the natural aroma substances of tobacco, as well as the aroma substances formed through the process of modulation, rebaking, fermentation and aging. However, due to the influence of objective conditions, the quality of tobacco fluctuates. Therefore, in the production of cigarettes, there is often a certain gap between product quality and formula requirements, showing defects such as insufficient and bland aroma, poor taste, heavy miscellaneous gas, irritating and spicy taste, etc. On the one hand, these gaps can be remedied by selecting appropriate raw materials to adjust the formula of tobacco leaves. On the other hand, the limitati...
