The average of the scores of 10 smokers was used as the score of the E-liquid for each of the examples and comparative examples, and the score was shown in Table 12 below.
TABLE 12 Overall evaluation results of E-liquid of examples and comparative examples
| Sample (I) | Evaluation of Whole mouthfeel | Evaluation of bulk fragrance |
| Example 1 | 8.5 | 9.2 |
| Example 2 | 9.3 | 9.5 |
| Example 3 | 9.6 | 9.7 |
| Example 4 | 9.8 | 9.9 |
| Example 5 | 8.8 | 9.4 |
| Example 6 | 8.3 | 9.1 |
| Example 7 | 7.9 | 8.9 |
| Comparative example 1 | 7.5 | 8.9 |
| Comparative example 2 | 8.4 | 8.9 |
| Comparative example 3 | 7.1 | 8.5 |

| Comparative example 11 | 7.9 | 9.0 |
| Comparative example 12 | 7.7 | 8.5 |
| Comparative example 13 | 7.0 | 8.6 |
| Comparative example 14 | 7.7 | 8.7 |
As can be seen from tables 9 to 12, the evaluation of the overall taste and the evaluation of the overall flavor of the electronic cigarette oils prepared in examples 1 to 6 are all 7.9 or more and 8.9 or more, and the evaluation of the overall taste and the evaluation of the overall flavor of the electronic cigarette oils prepared in examples 2 to 4 are better and are both 9.3 or more, which has the advantages of good taste and flavor.
As can be seen from comparison among comparative example 1, comparative example 2 and example 2, geranyl acetate is not added in the flavor composition, so that the fragrance reduction degree and fragrance richness of the prepared electronic cigarette oil are remarkably reduced, the stimulation feeling and the experience stability are also remarkably reduced, and the overall taste is poor. The addition of excessive geranyl acetate in the flavor composition has poor reduction degree, poor coordination and poor experience stability although the aroma is strong, so that the overall taste is poor.
As can be seen from comparison among comparative example 3, comparative example 4 and example 3, the flavor composition does not contain methyl anthranilate, the prepared electronic cigarette oil has poor reduction degree, naturalness and harmony, poor experience stability and a taste evaluation score of only 7.1; when the amount is excessive, the degree of flavor reduction and stability are improved, but the naturalness and harmony are still poor.
As can be seen from comparison of comparative examples 5 to 6 and example 4, although the ethyl propionate and the ethyl butyrate have similar structures, the effects are different, when one of the contents is reduced and the other content is increased, the total content of the two contents is still unchanged, but the reduction degree, the richness, the naturalness and the harmony of the correspondingly prepared electronic cigarette oil are poor, and the overall evaluation scores of the taste and the fragrance are reduced by 1-2 points.
As can be seen from comparison among comparative examples 7 to 8 and example 4, the contents of ethyl 2-methylbutyrate and methyl anthranilate are too high or too low, so that the reduction degree, naturalness, harmony, aftertaste feeling and the like of the correspondingly prepared electronic cigarette oil are not good enough, and the overall evaluation scores of the taste and the fragrance are reduced by about 1 point.
Therefore, in the flavor composition, the substances are mutually matched and have synergistic effect, so that when the flavor composition is used for preparing the electronic cigarette oil, the electronic cigarette oil has strong and natural grape fragrance, good taste and good stability.
In addition, as can be seen from comparison of comparative examples 9 to 14 with example 4, in the electronic cigarette liquid, too high or too low content of the flavor composition causes reduction in the aroma reduction degree, fineness, naturalness and the like of the electronic cigarette liquid, and the taste is poor. Too high nicotine content can also cause the reduction degree, coordination, stability and the like of the fragrance of the electronic cigarette oil to be obviously reduced, and the taste is poor. Too high or too low content of the essence also causes reduction of aroma reduction degree, fineness, naturalness and irritation of the electronic cigarette oil, and poor taste.
Therefore, in the electronic cigarette oil, the flavor composition, the tobacco essence, the cooling agent, the nicotine and the basic cigarette liquid are mutually matched and have synergistic effect, so that the electronic cigarette oil has strong, natural and fine grape fragrance, good taste and good stability.
