Problems solved by technology

[0003] There are many types of alkaline components in cigarette smoke and the content varies greatly. Nicotine accounts for more than 90% of the alkaline components in smoke, but the content of other basic flavor components is very low, and some of them are very small, such as the content of pyrazine compounds. It is about 5-50μg / branch, and it is difficult to separate and prepare these fragrance components with a small content

Embodiment 1

[0051] Separation of basic aroma components in the particulate matter of high-quality cigarette smoke:

[0052] (1) Extraction:

[0053] On the RM200A rotary smoking machine (Borgwaldt KC company), the filter capture method is used to collect high-quality tobacco smoke particles with Cambridge filters (92mm in diameter, each Cambridge filter collects 20 cigarette smoke particles) phase, to obtain Cambridge filter captures; 30 pieces of Cambridge filter captures that capture high-quality cigarette smoke particulate matter were first soaked in 750mL ether for extraction, then ultrasonically extracted for 5 minutes, then shaken for 30 minutes, and placed for a period of time. Two days later, after the extract was obtained, the extraction was repeated to obtain a total of 1500 mL of extract. Concentrate the two extracts obtained under reduced pressure to obtain 200mL concentrate O of the dark brown crude extract, i.e. the diethyl ether solution of the dark brown crude extract; wh...

Embodiment 2

[0080] Separation of basic aroma components in the particulate matter of high-quality cigarette smoke:

[0081] In addition to concentrating the extract obtained in step (1) under reduced pressure to obtain the concentrated solution O of the dark brown crude extract, the vacuum degree of concentration under reduced pressure in O is 740 mbar, and the temperature of the water bath is 33 ° C, and in step (2.2) After decompression concentration, the vacuum degree of the decompression concentration of the organic phase extract O1 was 740mbar, and the water bath temperature was 33°C. Other separation steps were the same as in Example 1, and finally the target alkaline fragrance component SF4 was obtained.

[0082] The basic fragrance component SF4 obtained in this example is detected by GC-MS, and its main fragrance substance is dimethylpyrazine, and the main substance is specifically 2-ethylpyrazine, 2,5-dimethylpyrazine, 2 ,6-dimethylpyrazine and 2,3-dimethylpyrazine. Dissolve th...

Embodiment 3

[0085] Separation of basic aroma components in the particulate matter of high-quality cigarette smoke:

[0086] In addition to concentrating the extract obtained in step (1) under reduced pressure to obtain the concentrated solution O of the dark brown crude extract, the vacuum degree of concentration under reduced pressure in O is 900 mbar, and the temperature of the water bath is 39 ° C, and in step (2.2) After concentrating under reduced pressure to obtain the organic phase extract O1, the vacuum degree of concentrating under reduced pressure is 900 mbar, and the temperature of the water bath is 39 ° C. The other separation steps are the same as in Example 1, and finally the target alkaline fragrance component SF4 is obtained.

[0087] The basic fragrance component SF4 obtained in this example is detected by GC-MS, and its main fragrance substance is dimethylpyrazine, and the main substance is specifically 2-ethylpyrazine, 2,5-dimethylpyrazine, 2 ,6-dimethylpyrazine and 2,3...

Abstract

The invention relates to a method for separating alkaline scent ingredients from the main stream smoke of cigarettes, in particular to a method for separating trace alkaline scent ingredients from alkaline ingredients containing a large amount of alkaloids such as nicotine and the like. The method comprises the following steps of: extracting collected smoke particulate matters, namely unblended cigarettes with high-quality tobacco leaves serving as raw materials, performing acid washing, concentrating, distilling under vacuum and the like to obtain a cut fraction F2 with low alkaloid content;separating the cut fraction by a gas chromatography separation method to obtain 5 cut fractions SF1 to SF5; and performing the combination of gas chromatography-mass spectrometry and sensory evaluation on SF1 to SF5, and selecting a cut fraction SF4 with an obvious sensory effect. By the method, a large number of alkaloid ingredients which do not contribute to the scent ingredients of the cigarettes are removed, and low-content active alkaline scent ingredients are enriched; and the method is applied to the field of the perfuming of cut tobaccos of the cigarettes, and has an important significance for improving the smoking quality of the cigarettes in China.

Description

technical field [0001] The invention relates to the separation of key alkaline trace aroma components in mainstream smoke of cigarettes, in particular to a separation method for separating trace alkaline aroma components from alkaline components in mainstream smoke of cigarettes containing a large amount of alkaloids. Background technique [0002] There are 1735 kinds of alkaline components in cigarette smoke, of which 1246 are nitrogen heterocycles. The nitrogen heterocycles in cigarette smoke are mainly nicotine, containing mesmin, cotinine, nornicotine, neonicotinoid, pseudobasine, Harman, norharman, 2,3-linked Pyridine and other alkaloids and gas-phase amine compounds, as well as a small amount of pyridine, pyrazine, pyrrole and other components. Most of the alkaloids are mainly transformed from tobacco into smoke in the process of smoking cigarettes. A part of the amines is formed by the direct transfer of part of the fatty amines in the tobacco into the smoke when th...
