Embodiment 1

[0043] Sample processing and instrument detection steps are as follows:

[0044] 1. Put the scented filter stick in a sealed container and heat it to the target temperature.

[0045] 2. After the temperature in the container rises to the target temperature, balance for about 5 minutes.

[0046] 3. After the balance is over, absorb and balance the volatiles emitted after heating. The absorbent used for absorption is glycerol triacetate. When absorbing the volatile matter emitted after heating, the absorption equilibrium time is 30 minutes.

[0047] 4. Add the absorbent after absorption balance to the detection instrument for analysis.

[0048] (1) Instruments and reagents: Agilent 7697A headspace autosampler, Agilent 7890B gas chromatograph and 5977A mass spectrometer.

[0049] (2) Adopt headspace-gas chromatography / mass spectrometry to measure triacetin content:

[0050] Headspace operations include:

[0051] S1. Accurately pipette 1mL of the absorbed absorbent into the h...

Embodiment 2

[0082] Using the processing method of Example 1, the detection conditions are basically the same as in Example 1, except that the equilibrium temperature of the sample bottle is set to 132°C, and the temperature of the sample loop is set to 165, 175, and 185°C, respectively. Detect the volatile fragrance components of the collected filter sticks, figure 1 , Figure 4 and Figure 5 GC-MS spectrograms obtained when the method provided by the present invention and the temperature of the sample loop are respectively 175, 165 and 185°C.

[0083] Will Figure 4 and figure 1 By comparison, it can be found that Figure 4 The number of peaks in the total ion map is small, and the amount of material information is insufficient. That is, when the sample ring temperature is 165 ° C, some components with higher boiling points are not fully vaporized. For example, peak No. 41 α-amylcinnamyl acetate Cannot be separated, such a situation will lead to inaccurate test results.

Embodiment 3

[0086] The detection conditions are the same as in Example 1. The present invention sets target temperatures of 80°C, 90°C, 100°C, 110°C, 120°C and 130°C respectively to simulate the cigarette burning process, and detects the volatiles in the above process. After the synthesis of the fragrance components released by temperature, the analysis of aroma and taste is carried out.

[0087] According to the detection method in Example 1, the scented filter stick and the non-fragranced filter stick are detected respectively, and the results are shown in Table 2 and Table 3:

Abstract

The invention provides a detection method of volatile perfume components in a perfumed filter stick, comprising the following steps: S1, heating the perfumed filter stick, then absorbing volatile matters from the perfumed filter stick with an absorbent to obtain the absorbent with the volatile matters absorbed, wherein the absorbent is glyceryl triacetate; S2, detecting the absorbent with the volatile matters absorbed in the S1 with an instrument; detection with the instrument in the step S2 comprises the following steps: S21, performing headspace treatment on the absorbent with the volatile matters absorbed to obtain a detecting sample; and S22, performing GC-MS detection on the detecting sample in the S21. The detection method concentrates on heating evaluation of the perfumed filter stick, solves the problem that correlated evaluation of the filter stick by using a cigarette sample is easy to be interfered, has precise detection parameters and high accuracy of results, and can provide a technical assurance for perfuming treatment of filter sticks and evaluation on perfume absorption of the filter sticks.

Description

technical field [0001] The invention belongs to the technical field of cigarette smoking detection technology, and more particularly relates to a method for detecting volatile fragrance components in flavored filter sticks. Background technique [0002] In order to enrich the smoking taste of cigarettes, it is an effective way to flavor the filter rod. The volatilization of the volatile fragrance components in the filter stick after being scented is one of the direct ways to evaluate the aromatization effect, so an effective detection method is needed to assist the research and development personnel to carry out the volatilization of the volatile fragrance components in the fragrance filter stick. evaluate. [0003] At present, one of the methods commonly used in the tobacco industry is to use the flavored filter rod sample to be tested to roll the smoke sample, and then detect the particle phase components in the mainstream smoke together with the smoke sample rolled using...
