Background
The smoke composition of tobacco is complex and contains over 5000 chemical constituents, of which nicotine is considered to be the most important pharmacological component. When smoking, nicotine enters the lung along with the smoke and then enters the blood circulation after being absorbed by the capillaries in the alveoli. The taken nicotine can rapidly pass through blood brain barrier, combine with nicotinic acetylcholine receptors (nAChRs) on the surface of central neurons, and act on the midbrain marginal dopamine system, thereby generating reward effect.
In recent years, some new food raw materials with high technological content and high purity in the biological field can be directly added into tobacco essence, the quality of the original essence is not changed, the functionality of cigarettes can be enhanced, the sensory quality can be improved, and the new fashion is achieved.
Gamma-aminobutyric acid (GABA), also known as aminobutyric acid, molecular formula C 4 H 9 NO 2 Molecular weight 103.1. It is a four-carbon non-protein amino acid, widely exists in bacteria, plants and vertebrates, and has important physiological functions. Gamma-aminobutyric acid is one of new food raw materials which are newly discovered in the field of biology and are beneficial to human bodies in recent years.

Example 2 solubility verification of GABA and fragrance
Group A: according to the dosage shown in the table 2, the gamma-aminobutyric acid is added into the solvent shown in the table 2 while stirring, then the essence is added, the mixture is stirred and then stands for 5min, and the condition that whether the bottom of the mixture is precipitated or crystallized or not is observed.
Group B: adding the essence into the solvent shown in the table 2 according to the dosage shown in the table 2, stirring while adding, then adding gamma-aminobutyric acid, stirring, standing, and observing whether the bottom of the mixture is precipitated, crystallized and the like after 5min.
The essence comprises the following components: the tobacco fragrant plate essence comprises 10 parts of tobacco fragrant plate essence, 5 parts of sweet fragrant plate essence and 5 parts of fresh sweet fragrant plate essence.
The test results are shown in Table 2.
TABLE 2 experimental solubility test results for GABA and essence
The test results of the A group and the B group show that the adding sequence of the gamma-aminobutyric acid does not influence the solubility and the stability of the system. However, the test results show that the gamma-aminobutyric acid belongs to a water-soluble substance, is insoluble or slightly soluble in an organic solvent, the tobacco tar of the electronic cigarette is an oil-soluble substance, and the gamma-aminobutyric acid is not easily dissolved in the tobacco tar of the electronic cigarette, so that the gamma-aminobutyric acid has more advantages when being used for traditional cigarettes and preparing cut tobacco essence.

the results of analyzing the substance content in the flue gas by GC-MS are shown in tables 5 and 6, wherein the chromatographic conditions of GC-MS are as follows:
chromatographic conditions are as follows: and (3) chromatographic column: HP-5MS UI capillary column (30 m × 0.25mm × 0.25 μm); carrier gas: helium, constant flow mode, flow rate 1.2mL/min; sample inlet temperature: 250 ℃; sample introduction amount: 1.0 μ L; the split ratio is as follows: 20: 1; temperature rising procedure: from 80 ℃ at 6 ℃/min to 140 ℃, and then at 20 ℃/min to 280 ℃, for 5min.

The professional was invited to perform sensory rating of the cigarette products obtained in examples 3-1 to 3-10 and comparative example 2 and the electronic cigarettes obtained in comparative examples 3-6, the sensory rating criteria are shown in table 7, and the sensory rating results are shown in fig. 2.
TABLE 4 content of gamma-aminobutyric acid in various examples and comparative examples
| Content of gamma-aminobutyric acid (. Mu.g/g) | |
| Example 3-1 | 0.697±0.059 |
| Examples 3 to 2 | 0.759±0.053 |
| Examples 3 to 3 | 0.652±0.047 |
| Examples 3 to 4 | 0.476±0.043 |
| Examples 3 to 5 | 0.769±0.047 |
| Examples 3 to 6 | 0.729±0.040 |
| Examples 3 to 7 | 0.610±0.052 |
| Examples 3 to 8 | 0.276±0.043 |
| Examples 3 to 9 | 0.316±0.043 |
| Examples 3 to 10 | 0.819±0.047 |
| Comparative example 2 | 0 |
| Comparative example 3 | 0 |
| Comparative example 4 | 1.265±0.089 |
| Comparative example 5 | 0.916±0.062 |
| Comparative example 6 | 0.892±0.075 |
As can be seen from Table 4, when the gamma-aminobutyric acid is added into the tobacco essence in different proportions, the gamma-aminobutyric acid with different contents is detected in the smoke respectively, and the content of the gamma-aminobutyric acid detected in the smoke is relatively increased along with the increase of the gamma-aminobutyric acid added into the tobacco essence, but the content of the gamma-aminobutyric acid in the comparative example 4-6 is significantly higher than that in the examples 3-1 to 3-10, which is probably because the combustion temperature of the cigarette is as high as 700 ℃, the atomization temperature of the electronic cigarette is about 200 ℃, and GABA in the traditional cigarette is more decomposed by heat, so that the GABA content in the examples 3-1 to 3-10 is relatively lower. However, in the aspect of evaluating the quality of cigarettes, the GABA content in the smoke is only a reference factor, and the effect of the GABA content in the smoke needs to be comprehensively compared by combining other components, solubility, sensory data and the like of the smoke.
TABLE 5 content of phenols in examples and comparative examples (. Mu.g/g)
Note: a. b, c and d represent significance respectively, the representation with the same letter in the superscript has no significance difference, and the representation with the same letter in the superscript has significance difference.
As can be seen from table 5, in the example, the tobacco essence contains gamma-aminobutyric acid, so that the content of phenolic substances in the smoke is reduced, the tobacco essence plays an important role in balancing the smoke, and the taste and the smell of the cigarette are improved. In contrast, in comparative examples 4 to 6, although gamma-aminobutyric acid was added, since the tobacco tar of the electronic cigarette is generally an oil-soluble substance and gamma-aminobutyric acid is a water-soluble substance, it is not easily soluble in the tobacco tar of the electronic cigarette, so that there is no significant difference in the content of the phenolic substances in comparative examples 4 to 6. As can be seen from table 5, the phenolics of the e-cigarette smoke are significantly higher than the traditional cigarette smoke.
TABLE 6 cigarette sensory Scoring standards
From fig. 2-5, it can be seen that: in the aroma score, the example scores higher than the comparative example, compared to the comparative example. In the smoke score, the score of the example was significantly higher than the comparative example, compared to the comparative example. In the harmony score, the scores of the examples were significantly higher than the comparative examples compared to the comparative examples. In the total score, similar to the harmony score, the score of the example was significantly higher than the comparative example.
Also, comparative example 3, comparative example 4, comparative example 5 and comparative example 6 have no significant difference in the fragrance, smoke, harmony and total, and comparative example 3, comparative example 4, comparative example 5 and comparative example 6 are low in the fragrance, smoke, harmony and total.

However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the technical solution of the present application.
